  • Ictal swearing network confirmed by stereoencephalography: a case report
    • Abstract: Ictal swearing, characterized by episodic utterance of deistic, visceral and other taboo words and phrases, is a rare manifestation of epilepsy. Limited manifestation of that elucidate neural network about manifestation of. Here we report a 43-year-old right-handed man who has suffered from refractory epilepsy manifestation of ictal swearing. The stereoencephalography(SEEG) investigation located the seizure onset zone in left orbito-frontal cortex and the involvement of left orbito-frontal and right hippocampus in the propagation of epileptic activities. Surgical resection has made the patient seizure-free. The present case gives us better understanding of these ictal phenomena and helps to optimize the placement of SEEG electrodes in refractory epilepsy patient with ictal swearing.

  • Intracranial WHO grade I meningioma: a competing risk analysis of
           progression and disease-specific survival
    • Abstract: Background Studies on meningioma are reported with inadequate allowance for competing causes of progression or death. The aim of this study was to describe the outcome of patients with intracranial WHO grade I meningioma and identify factors that may influence disease progression and cause-specific survival. Methods Pathology reports and clinical data of 505 WHO grade I meningiomas treated between January 2003 and December 2017 were retrospectively reviewed at a single institution. We estimated a cumulative incidence function for progression and cause-specific mortality. A competing risk analysis was conducted on clinical and histological criteria. Median follow-up was 6.2 years. Results A total of 530 surgical resections were performed on 505 cases. Forty-one patients received radiotherapy (RT). At data collection, 84 patients had died of their meningioma disease or demonstrated a recurrence eventually treated by redo surgery or RT. The risks of recurrence or meningioma-related death at 5 years were 16.2%, 95%CI[12.5, 20], whereas 5-year overall survival was 86.1%, 95%CI[82.8, 89.6]. In the multivariable Fine-Gray regression for a competing risk model, venous sinus invasion (SHR = 1.8, 95%CI[1.1, 2.9], p0.028), extent of resection (SHR = 0.2, 95%CI[0.1, 0.3], p < 0.001), and progressing meningioma (SHR = 7, 95%CI[3.3, 14.8], p < 0.001) were established as independent prognostic factors of cause-specific death or meningioma progression. In contrast, age at diagnosis < 65 years (HR = 1.1, 95%CI[1, 1.1], p < 0.001) and redo surgery for meningioma recurrence (HR = 2.6, 95%CI[1.4, 5], p = 0.00252) were predictors of the overall survival. Conclusions In this large series, WHO grade I meningioma treatment failure correlated with venous sinus invasion, incomplete resection, and progressing tumour; shorter survival correlated with increased age and redo surgery for recurrence. We recommend the cumulative incidence competing risk approach in WHO grade I meningioma studies where unrelated mortality may be substantial, as this approach results in more accurate estimates of disease risk and associated predictors.

  • How I do it: tapered rod placement across the cervicothoracic junction for
           augmented posterior constructs
    • Abstract: Background Posterior instrumentation techniques are commonly employed for cervicothoracic fixation. The pedicles of the upper thoracic vertebrae can typically accommodate larger diameter screws than the subaxial cervical vertebrae. In many construct systems, this requires the use of a tapered rod, which can be technically challenging to place. Method Using a three-dimensionally printed biomimetic spine simulator, we illustrate the stepwise process of instrumentation and tapered rod placement across the cervicothoracic junction (CTJ). Conclusion Tapered rod systems can augment the biomechanical stability of cervicothoracic constructs. Ease of rod placement across the CTJ hinges upon a systematic method of instrumentation.

  • Correlations between the trigeminal nerve microstructural changes and the
           trigeminal-pontine angle features
    • Abstract: Background Morphological and microstructural changes of the trigeminal nerve due to neurovascular compression (NVC) have been reported in primary trigeminal neuralgia (PTN) patients. This investigation was to examine the relationship between the trigeminal-pontine angle and nerve microstructural changes. Methods Twenty-five patients underwent microvascular decompression (MVD) for trigeminal neuralgia, and 25 age- and sex-matched controls were studied. The two groups underwent high-resolution three-dimensional MRI and diffusion tensor imaging (DTI). Bilateral trigeminal-pontine angle, cross-sectional area of cerebellopontine angle (CPA) cistern, and the length of trigeminal nerve were evaluated. The mean values of fractional anisotropy and apparent diffusion coefficient at the site of NVC were also measured. Correlation analyses were performed for the trigeminal-pontine angle and the diffusion metrics (FA and ADC) in PTN patients. Results The mean trigeminal-pontine angle and FA value on the affected side was significantly smaller than the unaffected side and the control group (p < 0.001), while the mean ADC value was significantly increased (p < 0.01). When taking the conflicting vessel types into consideration, the angle affected by the superior cerebellar artery (SCA) was statistically sharper than when affected by other vessels (p < 0.01). However, there were no significant changes in the area of the CPA cistern or the length of the trigeminal nerve between the groups. Correlation analyses showed that the trigeminal-pontine angle was positively correlated with FA and negatively correlated with ADC. Conclusions A sharp trigeminal-pontine angle may increase the chance of NVC and exacerbate nerve degeneration, which may be one of the supplementary factors that contribute to the pathogenesis of trigeminal neuralgia.

  • Extracapsular dissection in peripheral nerve schwannoma surgery using
           bright light and fluorescein sodium visualization: case series
    • Abstract: Background Schwannomas are the most frequent peripheral nerve sheath tumors and are treated by surgical resection when symptomatic. Tumor removal is performed by intraneural dissection and enucleation. In order to safely remove the tumor from the nerve, the use of sodium fluorescein has recently been proposed to distinguish the tumor from the adjacent normal nerve fibers, before incision of the tumor pseudocapsule and during intraneural tumor dissection. Methods We report a consecutive case series of 5 peripheral nerve schwannomas operated in 4 patients, in which we evaluate the usefulness of sodium fluorescein compared to usual visual landmarks, at each step of the surgical procedure. Results After exposition of the schwannoma, sodium fluorescein helped with the localization of intracapsular en passant nerve fascicles in only one case. Hence, the definition of a safe entry zone for capsular incision relied mainly on nerve monitoring and direct visualization of en passant nerve fascicles under microscope. During intraneural dissection, there was a sharp contrast between the fluorescent tumor and the non-fluorescent adjacent pseudocapsule in most cases but the colorimetric variation between tumor and normal tissue induced by fluorescence did not outperform the natural contrast between the yellow true capsule and the gray-red layers of the pseudocapsule. Conclusion Based on these results, we consider that the limited additional value of sodium fluorescein in primary peripheral nerve schwannoma surgery does not warrant its use in daily clinical practice. Additional studies are needed to assess its usefulness during the surgery of recurrences and tumors which are intertwined with several fascicles of origin such as neurofibromas.

  • Minimally invasive resection of a lumbar extradural schwannoma: how I do
           it
    • Abstract: Background Complete surgical resection of a foraminal lumbar schwannoma may require an extended surgical exposure and facetectomy and thus secondary instrumentation. The minimally invasive technique through the use of tubular retractors may represent a valid surgical alternative. Method We describe the resection of a foraminal lumbar schwannoma through the use of tubular retractors, along with its advantages and limitations. A limited medial facetectomy was performed and no stabilization was needed. Conclusion Minimally invasive surgery is suitable for an efficient and safe resection of foraminal schwannomas and may help in avoiding stabilization when a limited facetectomy is performed.

  • The transcallosal transchoroidal approach to the
           diencephalic-mesencephalic junction: how I do it
    • Abstract: Background Different approaches have to be considered for lesions of the diencephalic-mesencephalic junction based on the localization, extension of the lesion, and relationship to the ventricular system. Method We present the case of a young lady who presented with a cavernoma of the junction of midbrain and diencephalon after an episode of hemorrhage. The microsurgical anatomy of the trans-callosal trans-choroidal approach for this lesion is described along with its advantages and limitations. Conclusion The trans-choroidal approach allows adequate access to lesions of the diencephalic-mesencephalic junction that project into the third ventricle.

  • A new technique of endoscopic decompression of suprasellar
           craniopharyngioma cyst
    • Abstract: Introduction Craniopharyngiomas represent a unique management challenge. Aggressive surgical management has traditionally been associated with high rates of morbidity. Modern surgical techniques, and increasing practice of subtotal resection followed by radiosurgery, have reduced morbidity and mortality rates. One cause of postoperative morbidity, and indeed mortality, is aseptic meningitis from spill-out of craniopharyngioma cyst contents. We have developed a surgical technique for the management of large craniopharygngioma cysts extending into the third ventricle, to reduce this risk. Methods We describe a technique of using an epidural catheter, inserted into the working channel of a neuroendoscope, to decompress the cystic portion of a craniopharyngioma cyst before opening the cyst wall widely, preventing spill-out of large volumes of cyst content into the ventricular system. Results We have had no cases of aseptic meningitis, nor any complications, from use of the described technique. Discussion We believe that this is a safe and effective technique of decompression and fenestration of large suprasellar craniopharyngioma cysts that reduces rates of aseptic meningitis and the associated morbidity and mortality from this.

  • How I do it: combined petrosectomy
    • Abstract: Background Petroclival lesions are among the most complex to address in skull base surgery, being closely related to critical neurovascular structures and brainstem. The combined petrosectomy allows a wide exposure of large petroclival lesions with short working distance and provides multiple angles of attack, while limiting brain retraction. Method We describe in a step-wise fashion the surgical steps of the combined petrosectomy. Conclusion Combined petrosectomy with posterior transposition of the transverse-sigmoid sinus provides a wide surgical corridor to the ventral brainstem, middle and upper clivus, and infra-retrochiasmatic region.

  • Extra-intradural extracavernous subtemporal approach for chondrosarcomas:
           technical note and case report
    • Abstract: Background Skull base chondrosarcomas are rare tumors often invading the petrous apex and cavernous sinus, and many surgical approaches have been described. For most of them, these tumors grow slowly and their partial removal can be a first option before complementary radiotherapy. We described herein a minimally invasive approach that could be useful for soft non-calcified chondrosarcomas. Method and results We report a case of right parasellar chondrosarcoma, for which an extra-intradural extracavernous subtemporal approach allowed a safe effective partial removal. Conclusion This surgical approach is indicated in selected cases to obtain good decompression or partial removal of lesions involving the parasellar space and the petrous apex.

  • Hearing preservation in vestibular schwannoma surgery via retrosigmoid
           transmeatal approach
    • Abstract: Background Advances in various diagnostic and/or treatment modalities, including radiological imaging, neuromonitoring, and microsurgical techniques, have resulted in treatments of vestibular schwannomas being aimed at preserving facial and hearing functions while achieving optimal tumor control. Method We describe our surgical technique for hearing preservation in vestibular schwannoma surgery. Conclusion The retrosigmoid transmeatal approach under continuous neuromonitoring (auditory brainstem response, cochlear nerve action potentials, and continuous facial nerve monitoring) enables gross-total resection of vestibular schwannomas, while preserving hearing and facial functions. Radiological assessment and microsurgical techniques, such as meticulous tumor dissection, are also essential for functional preservation with sufficient tumor removal.

  • How I do it' Endoscopic discectomy using a new trocar “Endospine
           Plus” for lumbar prolapsed intervertebral disc
    • Abstract: Background Endoscopic spine surgery is a promising minimally invasive technique and use of trocars like Metrx (Neurosurgery 51(5):S129–36, 2002), Destandau (Neurol Res 21:39–42, 1999), and Easy go (Acta Neurochir (Wien) 151:1027‑33, 2009) has revolutionized this field. However, the steep learning curve makes this procedure elusive to many parts of the world. Methods The authors describe the technique of pure endoscopic discectomy using a specialized trocar devised by the senior author “Endospine Plus” which makes the technique easy to learn along with the advantages and complications of the procedure. Conclusions Endoscopic lumbar discectomy is a safe and effective technique for the treatment of prolapsed intervertebral disc.
