  • Transpalatal advancement pharyngoplasty for obstructive sleep apnea: a
           systematic review and meta-analysis
    • Authors: Keith Volner; Brandyn Dunn; Edward T. Chang; Sungjin A. Song; Stanley Yung-Chuan Liu; Scott E. Brietzke; Peter O’Connor; Macario Camacho
      Pages: 1197 - 1203
      Abstract: Abstract The objective is to determine if apnea-hypopnea index (AHI) and lowest oxygen saturation (LSAT) improve after transpalatal advancement pharyngoplasty (TPAP) with obstructive sleep apnea (OSA) in adults, using a systematic review and meta-analysis. Nine databases, including PubMed/MEDLINE, were searched through April 1, 2016. All studies that included patients who underwent TPAP alone were included in this analysis. Fifty-six studies were potentially relevant, 37 were downloaded and five studies met criteria with 199 patients (age: 42.5 ± 9.7 years and body mass index: 29.0 ± 4.0 kg/m2). The grand mean (M) and standard deviation (SD) for AHI (199 patients) pre and post-TPAP decreased from 54.6 ± 23.0 [95 % CI 51.4, 57.8] to 19.2 ± 16.8 [95 % CI 16.9, 21.5] events/h (relative reduction: 64.8 %). Random effects modeling demonstrated a mean difference (MD) of −36.3 [95 % CI −48.5, −24.1], overall effect Z = 5.8 (p < 0.00001), and I 2 = 85 % (significant inconsistency). The standardized mean difference (SMD) for TPAP demonstrated a large magnitude of effect for AHI −1.76 [95 % CI −2.4, −1.1]. For LSAT (70 patients), the pre and post-TPAP M ± SD improved from 81.9 ± 8.1 [95 % CI 80.0, 83.8] to 85.4 ± 6.9 [95 % CI 83.8, 87.0], with a MD of 3.55, overall effect Z = 1.79 (p = 0.07). Thus far, few studies have evaluated transpalatal advancement pharyngoplasty; therefore, we recommend additional studies, especially prospective studies. Research comparing TPAP to pharyngoplasty procedures without palatal advancement would help determine the optimal role for this procedure.

      Abstract: Abstract Congenital nasal anomalies are rare malformations with a broad spectrum of defects. The only existing classification strictly relating to nasal anomalies was presented by Losee et al. (Plast Reconstr Surg 113(2):676–689, 2004). The aim of this paper is to propose some suggestions, based on our current knowledge and experience gained by treating our patients in the clinic, in creating a specification of patients with congenital nasal anomalies. All patients with congenital nose defects treated in our health center were selected for this study. The research was retrospective and included years from 1995 to 2015. Nasal anomaly associated with cleft lip and palate was excluded. Patients were classified into four categories of congenital nasal anomalies, according to Losee et al. classification. In the period of 20 years, 191 patients with congenital nasal anomalies were treated in our health center. Type 1 defects were found in 124 patients, type 2 in 15, type 3 in 32 and type 4 in 20 patients. The nasal defect accompanying craniofacial syndrome is the most common type of nose malformation. The nose cleft is not always a part of craniofacial clefts; isolated forms of such malformations can occur. Vascular anomalies, due to different etiology, categorization and treatment, should not be recognized as nasal malformation.

      Abstract: Abstract Dizziness is a common medical condition that has been related to falls in the elderly, and it is, therefore, considered a severe social health problem. Particularly in the elderly, the impact of dizziness may be relevant, as it has been linked to several conditions, such as isolation, depression, reduced self autonomy, and self control. The social, functional, and psychological well-being of those affected can be hampered significantly, thus reducing the quality-of-life (QoL) perception. In addition, due to the aging of the population in the developed world, dizziness is becoming a growing public health problem; an optimal management of this condition includes, nowadays, the improvement of rehabilitative programs, as well as the evaluation of QoL status and its management. The aim of this paper is to evaluate the impact of dizziness on the QoL in the elderly, also analyzing the instruments available, nowadays, to evaluate QoL of dizzy patients.

  • Associations between the probabilities of frequency-specific hearing loss
           and unaided APHAB scores
    • Authors: J. Löhler; B. Wollenberg; P. Schlattmann; N. Hoang; R. Schönweiler
      Pages: 1345 - 1349
      Abstract: Abstract The Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire reports subjective hearing impairments in four typical conditions. We investigated the association between the frequency-specific probability of hearing loss and scores from the unaided APHAB (APHABu) to determine whether the APHABu could be useful in primary diagnoses of hearing loss, in addition to pure tone and speech audiometry. This retrospective study included database records from 6558 patients (average age 69.0 years). We employed a multivariate generalised linear mixed model to analyse the probabilities of hearing losses (severity range 20–75 dB, evaluated in 5-dB steps), measured at different frequencies (0.5, 1.0, 2.0, 4.0, and 8.0 kHz), for nearly all combinations of APHABu subscale scores (subscale scores from 20 to 80%, evaluated in steps of 5%). We calculated the probability of hearing loss for 28,561 different combinations of APHABu subscale scores (results available online). In general, the probability of hearing loss was positively associated with the combined APHABu score (i.e. increasing probability with increasing scores). However, this association was negative at one frequency (8 kHz). The highest probabilities were for a hearing loss of 45 dB at test frequency 2.0 kHz, but with a wide spreading. We showed that the APHABu subscale scores were associated with the probability of hearing loss measured with audiometry. This information could enrich the expert’s evaluation of the subject’s hearing loss, and it might help resolve suspicious cases of aggravation. The 0.5 and 8.0 kHz frequencies influenced hearing loss less than the frequencies in-between, and 2.0 kHz was most influential on intermediate degree hearing loss (around 45 dB), which corresponded to the frequency-dependence of speech intelligibility measured with speech audiometry.

      Pages: 1375 - 1381
      Abstract: Abstract Microbial infection is one of the most significant causes of ear diseases, but microbial profiles are very diverse according to the diseases and change over time. The purpose of the study was to clarify differences and chronological changes in causative pathogens among infectious ear diseases over the last 20 years, and to identify antibiotic resistance. In total, 1191 isolates were included from patients diagnosed with chronic otitis media without cholesteatoma (COM), cholesteatomatous otitis media (Chole), middle ear effusion (MEE), including acute otitis media and otitis media with effusion, and external otitis (EO). Data were collected periodically for the years 1995, 2000, 2004, 2009, and 2013. Culture results and antibiotic resistance were assessed. The most common microorganism identified was S. aureus. The microbial profiles differed significant among the COM, Chole, and MEE groups (p < 0.001). In contrast, there was no distinct difference between COM and EO (p = 0.332). COM, Chole, and MEE also showed significant chronological changes in microbial profiles over time. The frequency of CNS increased markedly in COM and Chole (p = 0.029 and 0.028, respectively); however, S. pneumoniae infection decreased significantly in MEE (p = 0.016). Methicillin-resistant S. aureus (MRSA) demonstrated a constant trend (p = 0.564), whereas ciprofloxacin-resistant P. aeruginosa increased over time (p < 0.001). Microbial profiles have changed over a 20-year period. Increases in the frequency of coagulase-negative Staphylococcus (CNS) and bacterial resistance to ciprofloxacin, used widely in treating ear infections, are noteworthy.

  • Olfaction in chronic rhinosinusitis: comparing two different endonasal
           steroid application methods
    • Authors: Sophia C. Poletti; Islam Batashev; Jens Reden; Thomas Hummel
      Pages: 1431 - 1435
      Abstract: Abstract Limited olfactory improvement after topical steroid therapy in chronic rhinosinusitis (CRS) patients might result from restricted drug access to the olfactory cleft. The aim of our study was to investigate the difference between two methods to topically administer steroids with respect to olfaction: (1) conventional nasal spray and (2) a device using pressure and vibration to distribute steroid aerosol endonasally. A prospective study was performed in patients with olfactory impairment due to chronic rhinosinusitis with and without nasal polyps. While the first group used the conventional dexamethasone nasal spray, the second group used the device over a period of 12 days. Olfactory testing was done at 0, 2, and 8 weeks using Sniffin’ Sticks test. A significant olfactory improvement was found after 2 weeks of treatment with either steroid (p = 0.005). However, there was no significant difference between the different methods of steroid application. There is a significant olfactory improvement in CRS patients following topical dexamethasone therapy, but no obvious superiority of one of the two ways to administer the steroid.

      Abstract: Abstract The true incidence of inverted papilloma (IP) is not yet known. From hospital-based studies, its incidence has been estimated to approximately 0.5/100,000 person years. Earlier hospital case studies have shown that IP can undergo a malignant transformation in 1–53 %. The frequency of its malignant transformation on a population basis is unknown. To our knowledge, no standardised incidence ratio (SIR) has been reported for malignancies among IPs. This study aims to investigate these incidences on a population basis. Using the data from the Swedish Cancer Registry (SCR), we have identified patients with IP and patients with Squamous Cell Carcinoma (SCC) diagnosed between 1960 and 2010 in Sweden. Incidence of IP and incidence of SCC among patients with IP and SIR were analyzed. Eight hundred and fourteen patients with IP were identified. The incidence of IPs reported to the SCR increased from 1960 to 2010. In this cohort, SCC was overrepresented, as compared with the general population. The incidence of IP in the Swedish population seems to have increased.

      Abstract: Abstract Chronic rhinosinusitis (CRS) and chronic otitis media (COM) are common diseases in the otorhinolaryngology field. Although clinicians frequently encounter patients presenting both diseases simultaneously, a few studies have shown relationships between them. We examined whether CRS was associated with COM in adults who participated in the Korea National Health and Nutrition Examination Survey from 2009 to 2012. A total of 27,492 participants were examined in this cross-sectional epidemiological study. Regression analyses was performed and adjusted for socio-demographics, general health behavior, and other comorbidities. All analyses used complex sampling designs; subgroup analyses were performed according to age, hearing loss, and the presence of cholesteatoma or nasal polyps. The weighted prevalence of COM and CRS was 3.6 ± 0.2 and 6.0 ± 0.2%, respectively. COM prevalence was significantly higher in subjects with CRS (5.1%) than in those without (3.5%). In the multivariate analysis, COM was more prevalent in subjects with CRS (adjusted odds ratio = 1.738; P = 0.038) after adjusting for other factors. The subgroup analysis showed that this association was significant only in older subjects (≥50 years) with nasal polyps. Non-serviceable hearing and cholesteatoma were not significantly associated with CRS. Our findings demonstrated that CRS with nasal polyps might be associated with COM in older patients.

      Pages: 1501 - 1505
      Abstract: Abstract The aim of this study is to present our management protocol of sphenopalatine artery bleeding, demonstrating that nasoendoscopic cautery (NC) was a more effective method than the nasal packing, in terms of shorter inpatient stay and reduced complications rate. We present ten posterior epistaxis not resolved by nasal packing. Tabotamp® was placed in the area of sphenopalatine foramen and/or in those parts of the posterior nasal cavity, where it was suspected that bleeding origins. In two cases, the bleeding was resolved in this way, instead eight cases needed of subperiosteal cauterization of sphenopalatine artery by Dessi bipolar forceps (MicroFrance®). 4 of these 8 patients evidenced a remarkable bleeding removing nasal packing (Hb before-nasal packing = 15 ± 0.69 versus Hb after-nasal packing = 13.3 ± 0.81; t student = 2.94; p value = 0.025). These four patients showed a deviation of the nasal septum ipsilateral to epistaxis, and according our experience, a traumatism of sphenopalatine area can be caused by Merocel® nasal packing in this condition. During follow-up, no recurrences of nasal bleeding have been observed in such patients. Nasal packing must be considered if posterior epistaxis is severe, but always taking into account the specific anatomy of patient and in particular septal spurs that can further compromise sphenopalatine artery. In our experience, the endoscopic endonasal cauterization of the sphenopalatine branches represented a safe and effective procedure.

      Abstract: Abstract Infection is a serious complication after nasal packing that otolaryngologists seek to avoid. The aim of this study is to investigate the use of silver (Ag) nanoparticle, which serves as antimicrobial agents, with nasal tampons. The study design is an experimental animal model and the setting is tertiary referral center. Twenty-four rats were randomized into the following four groups: (1) control group (n = 6); (2) silicone nasal splint (SNS) group (n  =  6); (3) polypropylene-grafted polyethylene glycol (PP-g-PEG) amphiphilic graft copolymer-coated SNS group (n  =  6); and (4) Ag nanoparticle-embedded PP-g-PEG (Ag-PP-g-PEG) amphiphilic graft copolymer-coated SNS group (n  =  6). These tampons were applied to rats for 48 h, after which they were removed in a sterile manner, and the rats were sacrificed. The nasal septa of the rats were excised, and assessments of tissue changes in the nasal mucosa were compared among the groups. The removed tampons were microbiologically examined, and quantitative analyses were made. When the groups were compared microbiologically, there were no significant differences in bacterial colonization rates of coagulase-negative Staphylococcus spp. among the three groups (p = 0.519), but there was a statistically significant difference among bacterial colonization rates of Heamophilus parainfluenzae and Corynebacterium spp. (p = 0.018, p = 0.004). We found that H. parainfluenzae grew less robustly in the Ag-PP-g-PEG than the PP-g-PEG group (p = 0.017). However, we found no significant difference between the Ag-PP-g-PEG and SNS groups, or between the SNS and PP-g-PEG groups. The growth of Corynebacterium spp. did not differ significantly between the Ag-PP-g-PEG and SNS groups (p = 1.000). When Group 4 was compared with Group 2, the former showed less inflammation. Compared with other tampons, Ag-PP-g-PEG amphiphilic graft copolymer-coated silicone nasal tampons caused less microbiological colonization and inflammation. Therefore, the use of these tampons may prevent secondary infections and reduce the risk of developing complications by minimizing tissue damage.

      Abstract: Abstract Previous published results have revealed that Rhinolight® intranasal phototherapy is safe and effective in intermittent allergic rhinitis. The present objective was to assess whether phototherapy is also safe and effective in persistent allergic rhinitis. Thirty-four patients with persistent allergic rhinitis were randomized into two groups; twenty-five subjects completed the study. The Rhinolight® group was treated with a combination of UV-B, UV-A, and high-intensity visible light, while the placebo group received low-intensity visible white light intranasal phototherapy on a total of 13 occasions in 6 weeks. The assessment was based on the diary of symptoms, nasal inspiratory peak flow, quantitative smell threshold, mucociliary transport function, and ICAM-1 expression of the epithelial cells. All nasal symptom scores and nasal inspiratory peak flow measurements improved significantly in the Rhinolight® group relative to the placebo group and this finding persisted after 4 weeks of follow-up. The smell and mucociliary functions did not change significantly in either group. The number of ICAM-1 positive cells decreased non-significantly in the Rhinolight® group. No severe side-effects were reported during the treatment period. These results suggest that Rhinolight® treatment is safe and effective in persistent allergic rhinitis.

  • Types of laryngomalacia in children: interrelationship between clinical
           course and comorbid conditions
    • Authors: Beata Kusak; Ewa Cichocka-Jarosz; Urszula Jedynak-Wasowicz; Grzegorz Lis
      Pages: 1577 - 1583
      Abstract: Abstract The aim of this study was to: (1) find out whether laryngomalacia (LM) types are related to clinical course; (2) which patients with LM are at higher risk of other airway malacia [tracheomalacia (TM) and/or bronchomalacia (BM)]; and (3) evaluate the prevalence of LM in our region. Patients with established LM diagnosis and complete clinical and endoscopy records were enrolled. They were classified into different LM types according to classification based on the side of supraglottic obstruction. One hundred ten children were included. The most common LM appearance was type I—58 children, followed by combine types (I + II and I + III)—38. The other airway malacia were found in 47 patients: TM in 31, BM in 10, and TM with BM in 6. Other comorbidities (cardiac, neurological, and genetic disorders) were identified in 30 children. Patients with combine types of LM differ from those with single type of LM in terms of prematurity (13 vs 31 %, p = 0.04) and higher weight on the examination day (p = 0.006). Patients with other airway malacia differ from children with isolated LM in terms of prematurity (40 vs 13 %, p = 0.008), comorbidities (38 vs 19 %, p = 0.024), and lower weight on the examination day (p = 0.014). The prevalence of clinically relevant LM was one in 2600–3100 newborns. Clinical course of LM cannot be anticipated on the basis of solely endoscopic evaluation of the larynx. Comorbidities and prematurity increase the risk of other airway malacia. The prevalence of LM is relatively high in the middle-south part of Poland.

      Abstract: Abstract Vagus nerve stimulation (VNS) is a useful tool for drug-resistant epilepsy, but it induces known laryngeal side effects, with a significant role on patients’ quality of life. VNS patients may show persistent left vocal fold (LVF) palsy at rest and/or recurrent LVF adduction during stimulation. This study aims at electromyographically evaluating laryngeal muscles abnormalities in VNS patients. We compared endoscopic laryngeal evaluation data in six VNS patients with laryngeal muscle electromyography (LMEMG) carried out on the thyroarytenoid, cricothyroid, posterior cricoarytenoid, and cricopharyngeal muscles. Endoscopy showed LVF palsy at rest in 3/6 patients in whom LMEMG documented a tonic spastic activity with reduced phasic modulation. In four out of six patients with recurrent LVF adduction during VNS activation, LMEMG showed a compound muscle action potential persisting for the whole stimulation. This is the first LMEMG report of VNS-induced motor unit activation via recurrent laryngeal nerve and upper laryngeal nerve stimulation. LMEMG data were could, therefore, be considered consistent with the endoscopic laryngeal examination in all patient.

  • Laser tracheobronchoplasty: a novel technique for the treatment of
           symptomatic tracheobronchomalacia

      Pages: 1601 - 1607
      Abstract: Abstract The management of tracheobronchomalacia is a very challenging problem with few treatment options. This study aims to evaluate the outcomes of a novel surgical treatment for membranous tracheobronchomalacia. A consecutive series of patients with tracheobronchomalacia were treated with two to three holmium laser scarring surgeries of the hyperdynamic tracheal and bronchial walls for the purpose of stiffening them through fibrosis. Patients filled out a Dyspnea Index questionnaire before and after treatment. Ten patients were treated for their tracheobronchomalacia with a mean age of 54 years. Symptoms included severe dyspnea, dry cough, recurrent pulmonary infections, and respiratory failure. Fifty percent of patients presented with wheezing refractory to traditional treatment. Tracheobronchomalacia was associated with gastroesophageal reflux disease (n = 8), obstructive sleep apnea (n = 5), and tracheal stenosis (n = 3). Only 50 % of patients presented with morbid obesity. All cases showed significant improvement of their respiratory symptoms with a mean postoperative difference of 22.3 out of a maximum impairment score of 40 (P < 0.01) on the Dyspnea Index. The mean number of procedures was 2.3 per patient with the average laser energy delivered per procedure of 1600 J. Laser tracheobronchoplasty is a safe, easy to adopt, and effective technique for the treatment of membranous tracheobronchomalacia. It presents a simple alternative to the commonly used procedures like endoluminal stenting and open tracheobronchoplasty.

      Pages: 1643 - 1650
      Abstract: Abstract Few studies have analyzed the survival of patients with untreated head and neck cancer. The objective of this study is to assess the survival rates of untreated head and neck cancer patients and to determine why the patients were not treated. Using data from a national patient sample cohort (1,025,340 cases) from the Korean Health Insurance Review and Assessment Service, 605 patients with diagnoses of head and neck cancer (lip and oral cavity, oropharynx, hypopharynx, and laryngeal cancer) between 2003 and 2013 were evaluated. Cox proportional hazards modeling and multiple logistic regression analysis were performed. Of the considered cases of head and neck cancer, 32.2% were untreated. The median survival rate of untreated groups was 9 months. The untreated group showed poorer survival than the treatment groups. Old age [adjusted odds ratio (AOR) = 1.37, 95% confidence internal (CI) 1.25–1.49, P < 0.001] and low income (AOR = 0.94, 95% CI 0.89–1.00, P = 0.028) were related to not receiving treatment. Many head and neck cancers go untreated. Clinicians should focus on untreated patients and seek to understand the reasons for their lack of treatment.

  • Thyroid autoimmunity: is really associated with papillary thyroid
    • Authors: Alev Selek; Berrin Cetinarslan; Ilhan Tarkun; Zeynep Canturk; Berna Ustuner; Zeynep Akyay
      Pages: 1677 - 1681
      Abstract: Abstract The incidence of thyroid cancer has been greatly increasing. Several studies aimed to investigate biomarkers for prediction of thyroid cancer. Some of these studies have suggested that thyroid autoantibodies (TAb) could be used as predictors of thyroid cancer risk, but the correlation between TAb and PTC is still a matter of debate. The aim of this study is to evaluate thyroid autoimmunity and TAbs in patients with PTC and benign multinodular goiter (MNG) to investigate if TAbs and autoimmune thyroid disease (ATD) could predict thyroid malignancy. A total of 577 patients with thyroid papillary carcinoma (PTC) and 293 patients with benign MNG disease were enrolled postoperatively. Demographic features, thyroglobulin (TgAb) and thyroid peroxidase antibodies (TPOAb) and histologic outcome of the patients were evaluated. The prevalence of ATD and TgAb or TPOAb measurements was not statistically different in PTC and MNG groups. However, tumors were significantly smaller and tumor capsule invasion was seen less frequently in patients with PTC and ATD than without ATD. Patients without ATD had more advanced stage (TNM stage III/IV) tumors than with ATD. Only one of the 11 patients with distant organ metastasis had ATD. The present study demonstrated that the prevalence of ATD diagnosed even with histology or TAb positivity was not different in patients with PTC and MNG. However, having ATD might be associated with a better prognosis in PTC patients.

  • An evaluation on novel application of cone-beam CT imaging with

      Abstract: Abstract Due to the high risk of vascular and nerve damage during surgery, precise pre-operative evaluation of carotid body tumor (CBT) is important. We aim to apply intra-operative contrast-enhanced cone-beam CT (CBCT) with multi-volume technique in CBT evaluation, where the tumor, patent carotid arteries, and skull are demonstrated in three different colors, and to compare this novel technique with traditional computed tomography angiography (CTA). Seven CBT patients scheduled for traditional surgical removal were enrolled in this study between October 2013 and March 2016. For each patient, two CBCT scans were performed on the carotid region both pre- and post-operatively, with contrast injected into the common carotid artery directly. CT-like cross-sectional slices were then reconstructed with a dedicated workstation, and a novel multi-volume technique was further applied for advanced image post-processing. For all seven patients, the anatomic relationship between tumor and surrounding vessels was clearly demonstrated by reconstructed CBCT images with multiple fused volumes. Carotid was either completely or partially incarcerated by tumors. Interestingly, two sets of draining vein systems of CBT were found feeding into the internal jugular vein and the anterior vertebral venous plexus, respectively, which have not been revealed in pre-operative CTA. Post-operative CBCT confirmed the thorough removal of the tumor with an intact preservation of the internal carotid artery. CBCT with multi-volume technique outperforms CTA in discovering fine structures and revealing tumor–vessel relationship for CBT. This emerging imaging technique would offer more accurate diagnosis of CBT and assist in the decision of surgical plan.
