  • Template-guided implantation of the Bonebridge: clinical experience
    • Abstract: Abstract The surgical procedure for Bonebridge implantation cannot be done in some cases without exposing the dura mater or sigmoid sinus. Surgical simulation technol ogy can help to identify such difficulties prior to surgery and be used to clarify the optimal location and orientation of the device to be implanted. However, there has not been a simple strategy to drill the temporal bone at exactly the same location as that simulated on the computer. Based on our previous development of the surface template-assisted marker positioning (STAMP) method for performing image-guided otologic surgery, we recently developed a noninvasive guiding method, the BB-STAMP method, for performing image-guided Bonebridge implantation. Three patients underwent Bonebridge implantation at our surgical center during the years of 2013–2014. The authors in the simulation center supported the surgery using the BB-STAMP method. The time and effort required to prepare for the surgery were evaluated. In addition, a postoperative analysis was performed to assess the accuracy of placing the device in the planned location. The BB-STAMP method enabled the surgeon to precisely replicate the computer simulation in the real patient with submillimetric accuracy without complexity. Thus, the use of experienced and elaborative simulation coupled with the creation of a tailor-made three-dimensional template (BB-STAMP) enables surgeons to perform quick, precise and safe surgical procedures at distant institutions.

  • Endonasal dilatation of the Eustachian tube (EET) in children: feasibility
           and the role of tubomanometry (Estève) in outcomes measurement
    • Abstract: Abstract Studies on endonasal dilatation of the Eustachian tube (EET) utilizing a balloon catheter have shown encouraging results over the last years. This retrospective analysis presents our outcomes with EET in children with chronic obstructive dysfunction of the Eustachian tube, as well as the role of tubomanometry (TMM, Estève) as a diagnostic tool in the pre- and postoperative assessment of the Eustachian tube (ET) dysfunction. The data of 33 children, having undergone EET between September 2010 and March 2014, were retrospectively evaluated. They were assessed using tubomanometry before and after the EET. The R-data as the rate of Eustachian tube function in tubomanometry (TMM) were pre- and postoperatively matched with the clinical outcomes. Moreover, the patients’ complaints before and after the procedure were analyzed. We did not see any EET-related complications in children. Most patients noticed a relief of their complaints. In the same time, tubomanometry was not able to show improved tube function or favorable postoperative changes in the R-data. Ear-related symptoms (e.g. otorrhea, otalgia, hearing loss) have been improved. EET is a feasible method in adults as well as in children to treat chronic tube dysfunction. However, tubomanometry does not seem to be the adequate tool to evaluate the tube function and thus the success rate of EET in children with chronic dysfunction of the Eustachian tube.

  • The efficacy of honey for ameliorating pain after tonsillectomy: a
           meta-analysis
    • Abstract: Abstract Postoperative pain and wound healing following tonsillectomy can result in dissatisfaction for the patient. However, there is no consensus on whether postoperatively administered honey effectively reduces morbidity after tonsillectomy. Therefore, a systematic review with a meta-analysis of the efficacy of honey as a treatment for postoperative pain and wound healing was performed. Two authors independently searched the database records (MEDLINE, SCOPUS, and Cochrane databases) dating from inception to June 2014. Studies comparing postoperative oral administration of honey with administration of placebo where the outcomes of interest were pain and wound healing on postoperative days were included. Baseline study characteristics, study quality, numbers of patients in steroid-treated and control groups, and treatment outcomes were extracted. Sufficient data for meta-analysis were retrieved from 4 trials with a total of 264 patients. We analyzed patient-reported pain scores and quantities of administered analgesics during the first 5 postoperative days. The pain score was significantly decreased in the honey-treated patients in comparison with the placebo-treated patients on postoperative day 1 only, but the analgesic intake of the honey-treated patients on the first 5 postoperative days was significantly less than that of the placebo-treated patients. In addition, honey significantly increased tonsillectomy bed wound healing in comparison with placebo during the first 2 weeks after surgery. This meta-analysis shows that postoperative administration of honey after tonsillectomy significantly reduces pain and promotes wound healing. Further trials comparing honey with good research methodology should be conducted to confirm these results.

  • Consideration of vocal fold position in unilateral vocal fold paralyses
    • Abstract: Abstract The objective of this study was to improve the evaluation of unilateral vocal fold paralyses (uVFP) by means of an area measurement of the glottic plane, which describes the position of the paralysed vocal fold. The area measurements were related to electromyographic findings and clinical outcome (recovery, voice quality). In 56 patients (33 women and 23 men), uVFP were confirmed by endolaryngeal electromyography (EMG) of the paralysed vocal fold and cricothyroid muscles (CT). The EMG response was classified on a 4-point scale (from 0 to 3). Vocal fold position was divided into ‘paramedian’ and ‘intermediate’ and additionally quantified by measurement of the glottic area. An ‘area quotient’ (AQ) was calculated and related to the EMG findings and clinical outcome. Voice qualities were objectified regarding their additive noise (breathiness) and irregularity (roughness) using the ‘Göttingen Hoarseness Diagram’. The majority of uVFP was due to iatrogenic lesions. The AQ of classically graduated ‘paramedian’ and ‘intermediate’ vocal fold positions was significantly different but did not correlate with objective voice quality values. There were no significant correlations regarding EMG findings, duration or recovery from paralyses. Laryngeal EMG remains the gold standard for verifying uVFP. But EMG did not correlate significantly with AQ or functional outcome of uVFP. The measurement of an AQ is suitable for obtaining continuous data describing the position of paralysed vocal folds beyond the terms ‘paramedian’ or ‘intermediate’ and provides the basis for clinical evaluations of diagnostic tools and therapeutic interventions.

  • Patients with long-lasting dizziness: a follow-up after neurotological and
           psychotherapeutic inpatient treatment after a period of at least
           1 year
    • Abstract: Abstract Patients who experience chronic dizziness are considered to be difficult to treat. Persisting symptoms of vertigo can be caused by recurrent organic as well as a variety of psychogenic factors, the latter usually being part of anxiety and depression disorders. Psychotherapeutic interventions can achieve improvements, the effects, however, in general do not persist over a longer time. The purpose of this study is to investigate the long-term effects of a symptom-related indoor treatment including neurotological and psychotherapeutic approaches as well as vestibular and balance rehabilitation. 23 indoor patients 16 male patients and 7 female., mean age 56.6 years (SD 12) with chronic vestibular symptoms (longer than six months), who were treated with neurotological counseling, psychotherapy, vestibular and balance rehabilitation and—if necessary—antidepressant drugs during a lengthy hospital stay [average 40 days (SD 14)], were re-examined. After a time period of at least one year (average 32 months; SD 15) they were asked to answer a questionnaire concerning post-therapeutic status of dizziness, symptoms and coping strategies as well as the Hospital Anxiety and Depression Score (HADS D). 18 of 23 patients (78%) reported a sustained reduction in their vertiginous symptoms. Four patients did not report a persistent improvement and one even got worse. Patients with a chronic form of dizziness can improve through a coordinated neurotologic and psychotherapeutic approach including vestibular and balance rehabilitation.

  • Efficacy of sublingual immunotherapy for house dust mite allergic rhinitis
    • Abstract: Abstract In the present study, we investigated the outcomes of sublingual immunotherapy (SLIT) in house dust mite-induced allergic rhinitis (HDM-AR) patients. In this prospective, multicentric study, 186 patients with AR who had positive skin prick test results for HDMs were included. The patients were administered SLIT using Staloral 300 for 1 year. Evaluation of the patients regarding symptom scores, clinical findings and Rhinitis Quality of Life Questionnaire (RQLQ) scores was performed at baseline, and then at 6 and 12 months of therapy. Our results showed that, for all of the evaluated items (symptom scores, clinical findings and RQLQ scores), 12-month values were significantly lower than those at 6 months and baseline. Similarly, 6-month values were significantly lower than those at baseline. There were no complications in any of our patients. SLIT for HDM-AR is a treatment modality that can be used safely. We obtained better results than expected, and the treatment showed a positive psychological effect; the patients believed that SLIT was the final step of treatment and, which made them feel better.

  • Association between XRCC3 Thr241Met polymorphism and laryngeal cancer
           susceptibility in Turkish population
    • Abstract: Abstract DNA repair systems are essential for normal cell function. Genetic alterations in the DNA repair genes such as X-ray repair cross-complementing group 3 (XRCC3), can cause a change in protein activity which results in cancer susceptibility. The aim of this study was to investigate the association of XRCC3 Thr241Met single nucleotide polymorphism (SNP), smoking and alcohol consumption with the risk of laryngeal cancer in Turkish population. The frequencies of Thr241Met SNP were studied in 58 laryngeal cancer cases (SSC) and 67 healthy individuals. Genomic DNA was isolated from peripheral blood samples of both controls and laryngeal cancer cases. Thr241Met SNP was genotyped by polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) method. The genotype and allele frequencies of Thr241Met polymorphism were not statistically significant between the laryngeal cancer and control groups. Carrying mutant allele was not associated with the risk of laryngeal cancer. On the other hand, smoking and chronic alcohol consumption were associated with the risk of laryngeal cancer but there is no association between Thr241Met, smoking and alcohol consumption in laryngeal cancer cases. These results indicate that Thr241Met polymorphism was not associated with the development of laryngeal cancer in Turkish population. However, it should be kept in mind that the association of a polymorphism with cancer susceptibility can differ due to several factors such as cancer type, selection criteria, ethnic differences and size of the studied population.

  • TransOral endoscopic UltraSonic Surgery (TOUSS): a preliminary report of a
           novel robotless alternative to TORS
    • Abstract: Abstract The objective of this study is to describe and evaluate the feasibility of TransOral UltraSonic Surgery (TOUSS), a new endoscopic alternative to transoral robotic surgery for approaching pharyngeal and laryngeal tumours based on ultrasonic scalpel as a resection tool. This is a prospective study on 11 consecutive patients with pharyngeal and supraglottic carcinomas between December 2013 and August 2014. All tumours were resected transorally with 35 cm ThunderbeatTM. Exposure was achieved using GyrusTM FK-retractor and Olympus ENDOEYE Flex 5 mm 2D/10 mm 3D deflecting tip video laparoscopes. We evaluated tumour staging, surgical margins, surgical time, blood transfusions, tracheostomy, enteral feeding, postoperative pain and hospital stay. The operating room setup and procedure are described. This series comprised seven early and four locally advanced carcinomas. The mean setup for TOUSS and resection time were 16 and 70.9 minutes. No major intraoperative complications were identified. The average time of nasogastric feeding tube dependence (n = 9) was 13 days. Gastrostomy was performed in one patient. The average hospital stay was 14.3 days. Postoperative pain was satisfactory treated with nonsteroidal anti-inflammatory drugs. We have described TOUSS as a new feasible and intuitive procedure to approach endoscopically pharyngeal and supraglottic tumours, with good intraoperative conditions and functional outcomes.

  • Cross-cultural adaptation and validation of the sino-nasal outcome test
           (SNOT-22) for Spanish-speaking patients
    • Abstract: Abstract Our objective was to perform translation, cross-cultural adaptation and validation of the sino-nasal outcome test 22 (SNOT-22) to Spanish language. SNOT-22 was translated, back translated, and a pretest trial was performed. The study included 119 individuals divided into 60 cases, who met diagnostic criteria for chronic rhinosinusitis according to the European Position Paper on Rhinosinusitis 2012; and 59 controls, who reported no sino-nasal disease. Internal consistency was evaluated with Cronbach’s alpha test, reproducibility with Kappa coefficient, reliability with intraclass correlation coefficient (ICC), validity with Mann–Whitney U test and responsiveness with Wilcoxon test. In cases, Cronbach’s alpha was 0.91 both before and after treatment, as for controls, it was 0.90 at their first test assessment and 0.88 at 3 weeks. Kappa coefficient was calculated for each item, with an average score of 0.69. ICC was also performed for each item, with a score of 0.87 in the overall score and an average among all items of 0.71. Median score for cases was 47, and 2 for controls, finding the difference to be highly significant (Mann–Whitney U test, p < 0.001). Clinical changes were observed among treated patients, with a median score of 47 and 13.5 before and after treatment, respectively (Wilcoxon test, p < 0.001). The effect size resulted in 0.14 in treated patients whose status at 3 weeks was unvarying; 1.03 in those who were better and 1.89 for much better group. All controls were unvarying with an effect size of 0.05. The Spanish version of the SNOT-22 has the internal consistency, reliability, reproducibility, validity and responsiveness necessary to be a valid instrument to be used in clinical practice.

  • Effect of antibiotic use on bacterial flora of tonsil core in patients
           with recurrent tonsillitis
    • Abstract: Abstract The aim of this study was to investigate the effects of commonly used antibiotics on bacterial flora of the tonsil core. Patients who underwent tonsillectomy for recurrent chronic tonsillitis were included in the study. Three groups were formed: group 1 was treated for 10 days preoperatively with amoxicillin/clavulanic acid; group 2 was treated for 10 days preoperatively with clarithromycin; and group 3 included patients who underwent tonsillectomy without preoperative antibiotic use. The removed palatine tonsils were sent to our microbiology department in sterile tubes for bacteriological analysis. Seventy-three patients (group 1 = 19, group 2 = 20, group 3 = 34 patients) aged 3–18 years (mean 7 years) were included in the study. At least one bacterium was isolated from all tonsils, except for two cases in group 1; the difference in single bacterial growth among groups was not significant (p = 0.06). On the other hand, the numbers of patients with pathogenic bacterial growth was significantly lower in group 2 (n = 2) compared with group 1 (n = 10) and group 3 (n = 27) (p < 0.001). The bacterium isolated most frequently from the tonsils was Streptococcus viridans. Pseudomonas aeruginosa was the only pathogenic bacterium that grew in all three groups. Clarithromycin was more effective than amoxicillin/clavulanic acid in eradicating pathogenic bacteria in the tonsil core. Pseudomonas aeruginosa might be responsible for resistant or recurrent tonsil infections. To prevent endocarditis, antibiotic prophylaxis toward S. viridians, which is the most prevalent bacterium in the tonsil core, should be kept in mind for patients with heart valve damage.

  • Surgery of isolated malleus fixation due to tympanosclerosis
    • Abstract: Abstract The aim of the present study was to describe our surgical approach for isolated malleus fixation in patients with tympanosclerosis and to analyze the postoperative results. A total of 30 patients presented with isolated malleus fixation were operated. The fixation was reached via canalplasty. Fixated areas were cleaned without damaging the ossicle. Pre- and postoperative audiometric results were evaluated for each patient. Improvement of the pure-tone average (PTA) by at least 10 dB and an air-bone gap (ABG) of less than 20 dB after 12 months of follow-up was accepted to indicate success. The recovery of the postoperative PTA and ABG measurements was significant. Pre- and postoperative PTA was 48.00 ± 11.86 and 24.90 ± 12.45 dB, respectively (p < 0.001). According to PTA measurements, 40–50 dB recovery was achieved in four (13.3 %) patients, 31–40 dB in six (20 %) patients, 21–30 dB in ten (33.3 %) patients, and 11–20 dB in five (16.6 %) patients, with a total success rate of 25/30 (83.2 %). Pre- and postoperative ABG levels were 38.95 ± 9.92 and 16.10 ± 7.79 dB (p < 0.001), respectively. The ABG level was between 0 and 10 dB for 8 (26.6 %) patients, and 11–20 dB for 16 (53.3 %), with a total success rate of 24/30 (80 %). In cases of isolated malleus fixation with tympanosclerosis, performing a canalplasty to clean the sclerotic plaques without damaging the normal anatomy of the ossicle system using a diamond burr is a safe surgical option that provides significant recovery in hearing levels.

  • Interesting association of squamous cell carcinoma of soft palate and
           tuberculous lymphadenitis
    • Abstract: Abstract Squamous cell carcinoma is the most common malignancy of the soft palate. In some cases, it mimics mycobacterial infections and in others it can develop against the background of a previous tuberculosis infection. Here we report a case of a 68-year-old male who presented with squamous cell carcinoma of the soft palate. He had metastatic lymphadenopathy on the right side and, simultaneously, two caseating granulomatous lymphadenopathies without metastatic lymph nodes on the left side. The patient was treated with soft palate excision and bilateral functional neck dissection. Standard antitubercular therapy and radiotherapy were added postoperatively. To our knowledge this is the first case in the English-language medical literature of a head and neck cancer in the setting of tuberculosis. Tuberculosis may mimic head and neck cancers and vice versa, and both conditions may have atypical clinical and radiological presentations. Our case points out the need to consider tuberculosis in the differential diagnosis of squamous cell carcinoma of the head and neck.

  • A systematic review on skin complications of bone-anchored hearing aids in
           relation to surgical techniques
    • Abstract: Abstract A systematic review to study the skin complications associated with the bone-anchored hearing aid in relation to surgical techniques. The following databases have been searched: MEDLINE, EMBASE, the Cochrane Library , Google scholar and the PubMed. The literature search date was from January 1977 until November 2013. Randomised controlled trials and retrospective studies were included. Initial search identified 420 publications. Thirty articles met the inclusion criteria of this review. The most common surgical techniques identified were full-thickness skin graft, Dermatome and linear incision techniques. The result shows that dermatome technique is associated with higher rate of skin complications when compared to linear incision and skin graft techniques. Based on the available literature, the use of a linear incision technique appears to be associated with lower skin complications; however, there is limited data available supporting this. Higher quality studies would allow a more reliable comparison between the surgical techniques.

  • Effects of nasal septum perforation repair surgery on three-dimensional
           airflow: an evaluation using computational fluid dynamics
    • Abstract: Abstract The purpose of this research is to determine the cause of nasal perforation symptoms and to predict post-operative function after nasal perforation repair surgery. A realistic three-dimensional (3D) model of the nose with a septal perforation was reconstructed using a computed tomography (CT) scan from a patient with nasal septal defect. The numerical simulation was carried out using ANSYS CFX V13.0. Pre- and post-operative models were compared by their velocity, pressure gradient (PG), wall shear (WS), shear strain rate (SSR) and turbulence kinetic energy in three plains. In the post-operative state, the crossflows had disappeared, and stream lines bound to the olfactory cleft area had appeared. After surgery, almost all of high-shear stress areas were disappeared comparing pre-operative model. In conclusion, the effects of surgery to correct nasal septal perforation were evaluated using a three-dimensional airflow evaluation. Following the surgery, crossflows disappeared, and WS, PG and SSR rate were decreased. A high WS.PG and SSR were suspected as causes of nasal perforation symptoms.

  • The prognostic value of cyclin D1 expression in head and neck squamous
           cell carcinoma
    • Abstract: Abstract The correlation between cyclin D1 overexpression and the clinical outcome of head and neck cancer is not defined. The aim of this meta-analysis was to evaluate the prognostic value of cyclin D1 in patients with head and neck cancer. A search thorough Ovid MEDLINE was performed to enroll all eligible articles. Twenty-two studies comprising a total of 1,929 patients with different head and neck cancers were included. Cyclin D1 overexpression was significantly associated with lymph node metastasis [OR 2.25; 95 % confidence interval (CI) 1.76–2.87] and worse disease-free survival (OR 3.06; 95 % CI 2.42–3.87]. Subgroup analysis revealed that cyclin D1 overexpression correlated significantly with nodal metastasis for laryngeal cancer (OR 2.26; 95 % CI 1.61–3.16) and was a significant poor predictor for nasopharyngeal cancer (OR 4.44; 95 % CI 1.89–10.42). Our meta-analysis suggests that cyclin D1 overexpression could represent an important prognostic indicator for patients with head and neck cancer.

  • Laser-Doppler microvascular measurements in the peri-implant areas of
           different osseointegrated bone conductor implant systems
    • Abstract: Abstract The objective of this study was to evaluate the impact of hydroxyapatite coating of newly designed osseointegrated fixtures’ abutments on the postoperative complication rates. The integrity of peri-implant microcirculation was used as a marker to compare tissue viability after different surgical techniques. Laser-Doppler Flowmetry (LDF) measures alone, and coupled with heat provocation tests were applied to test the different microcircular patterns. Measures for 17 consecutively implanted patients (8 women, 9 men, ages ranged from 18 to 77 years) were recruited; seven with soft tissue reduction (STR); and 10 with soft tissue preservation (STP).Thirteen non-operated retro-auricular areas were examined as naive controls. In isotherm conditions the baseline blood flow remained stable in all groups. The naive control patients demonstrated significant changes of blood flux in the intact skin. The non-implanted yet previously operated contralateral sides of the patients demonstrated marginally lower (p = 0.09) blood flux index. The STR sides however, showed significantly lower (average 217 %) provoked blood flux compared to controls (p < 0.001). At the STP sides a maladaptation could be observed (average 316 %) compared to the contralateral sides (p = 0.53). STP sides demonstrated a significantly better blood flow improvement compared to the STR sides (p = 0.02). These results suggest a favorable postoperative condition of vascular microcirculation after STP, than after STR surgery. The possibly faster wound healing and lower potential complication rate may widen the inclusion criteria and maybe beneficial for the patient compliance with a better quality-of-life.

  • Long-term vocal outcomes of refined nerve-muscle pedicle flap implantation
           combined with arytenoid adduction
    • Abstract: Abstract The objective of this study is to evaluate long-term efficacy of refined nerve-muscle pedicle (NMP) flap implantation combined with arytenoid adduction (AA) for treatment of unilateral vocal fold paralysis (UVFP). The authors retrospectively reviewed 33 patients with UVFP who received refined NMP flap implantation with AA and were followed up over a 1-year period. Evaluation of vocal fold vibration (regularity, amplitude, and glottal gap), aerodynamic analysis (maximum phonation time [MPT] and mean airflow rate [MFR]), and perceptual evaluation (Grade and Breathiness) were performed preoperatively and at five different time points (1, 3, 6, 12, and 24 months) postoperatively. All voice parameters improved significantly postoperatively. All parameters except MFR also continued to improve over the course of 24 months. In the videostroboscopic analysis, the parameter for regularity 24 months after surgery was significantly improved compared with that at 1, 3, and 6 months after surgery. There were also significant improvements in amplitude and the glottal gap 24 months after surgery in comparison with values at 3 and 6 months after surgery and 3 months after surgery, respectively. Significant improvement in aerodynamic and perceptual measurements during the follow-up period together with near-normal vocal fold vibration was achieved by delayed reinnervation with refined NMP flap implantation and AA. The combined surgical technique is effective in the treatment of severe breathy dysphonia due to UVFP. Level of evidence 4.

  • Correlation between hippocampal sulcus width and severity of obstructive
           sleep apnea syndrome
    • Abstract: Abstract The aim of the present study was to evaluate the relationship between obstructive sleep apnea syndrome (OSAS) severity and the hippocampal sulcus width in a cohort of subjects with OSAS and controls. A total of 149 OSAS patients and 60 nonapneic controls were included in the study. Overnight polysomnograpy was performed in all patients. Hippocampal sulcus width of the patients was measured by a radiologist blinded to the diagnosis of the patients. Other variables noted for each patient were as follows: gender, age, body mass index, apnea hypopnea index, Epworth sleepiness scale, sleep efficacy, mean saturation, lowest O2 saturation, longest apnea duration, neck circumference, waist circumference, hip circumference. A total of 149 OSAS patients were divided into three groups: mild OSAS (n = 54), moderate OSAS (n = 40), severe OSAS (n = 55) groups. The control group consisted of patients with AHI <5 (n = 60). Hippocampal sulcus width was 1.6 ± 0.83 mm in the control group; while 1.9 ± 0.81 mm in mild OSAS, 2.1 ± 0.60 mm in moderate OSAS, and 2.9 ± 0.58 mm in severe OSAS groups (p < 0.001). Correlation analysis of variables revealed that apnea hypopnea index (rs = 0.483, p < 0.001) was positively correlated with hippocampal sulcus width. Our findings demonstrated that severity of OSAS might be associated with various pathologic mechanisms including increased hippocampal sulcus width.
