OBJECTIVE The objective of the study was to evaluate the outcomes of central neurocytoma treatments. METHODS Between 2003 and 2019, 23 post-operative patients with central neurocytoma were included in the study. According to the World Health Organization (WHO) 2021 classification, 14 patients were classified as atypical neurocytoma. Gross total resection was performed in 12 patients whereas subtotal resection (STR) was performed in ten patients and eight patients had residual disease. In total, 13 patients received radiotherapy (RT), nine of whom were irradiated postoperatively, and four patients were irradiated after relapse. Recurrence and progression-free survival (PFS) of each subgroup were presented. RESULTS The median follow-up was 59 months (15-262 months). The 5-year overall survival (OS) was 89.3% and PFS was 83.4%. During follow-up in total three patients died; two patients had disease progressionrelated death, and one patient died because of his comorbidities. Comparing the outcome of RT group and the observation group; there was no recurrence in the radiotherapy group, but three recurrences or progression were detected in the observation arm. There was no statistical significance (p=0.257) due to the low number of patients in this subgroup. Patients with extraventricular tumors received postoperative radiotherapy; however, patients had recurrences and died due to disease progression. Furthermore, there was no statistical significance (p=1.00) when the operation type was evaluated. In terms of histopathology, recurrence or progression was observed in two patients with typical CN and one patient with atypical histology, which was not statistically significant (p=0.247). CONCLUSION All treatment modalities were applied in our cohort, but due to the small number of patients, the significance of any modality could not be demonstrated. However, the prognosis of the patients with extraventricular pathology was very poor and two patients died due to the disease. [ABSTRACT FROM AUTHOR]

The objective of this study is to define the endoscopic anatomy of the oculomotor nerve (CN III) and its neurovascular relations in order to facilitate surgical procedures and avoid injury to this nerve during endoscopic endonasal approach to the skull base. Endoscopic anatomy of the cavernous sinus was studied in seven fresh adult cadavers bilaterally and the basal cisterns in five fresh adult cadavers. Extended endoscopic endonasal suprasellar approach was performed to expose the oculomotor nerve in the interpeduncular cistern and the endoscopic endonasal transethmoidopterygoidosphenoidal approach to expose the oculomotor nerve within the cavernous sinus. The extraorbital part of the oculomotor nerve can be divided into three segments in regard to the cisterns and venous spaces that are being transected: the interpeduncular segment, the cisternal segment, and the intercavernous segment. Of these segments, only the cisternal segment could not be exposed since this segment was located at the initial part of the roof of the cavernous sinus, anterolateral to the posterior clinoid, and posteroinferior to the anterior clinoid processes. Thus, cisternal segment of the oculomotor nerve was considered a blind spot during endoscopic approaches to the skull base. We defined the endoscopic anatomy of the CN III and the related neurovascular structures and proposed a new segmental classification of extraorbital oculomotor nerve. Awareness of the endoscopic anatomy and the new segmental classification of the CN III may prove helpful in avoiding the risk of nerve injury during endoscopic endonasal surgery for skull base pathologies.

Spinal or paraspinal retained surgical sponges (gossybipoma or textiloma) are rare incidents and mostly asymptomatic in chronic cases, but can be confused with other masses such as a hematoma, an abscess or a tumor. In chronic cases, the presentation can be as late as decades after the initial surgery; however, some gossybipomas cause infection or abscess formation in the early stages. The authors report a 40-year-old woman with a history of operation for lumbar disk herniation before 8 months, and got admitted with a complaint of serous fluid leakage from the operation wound. In this report, the authors discuss the clinical presentation, the radiologic findings and the differential diagnosis of gossybipoma. [ABSTRACT FROM AUTHOR]

The clinical study consisted of 27 patients and 30 hands that were operated on with the biportal endoscopic carpal tunnel release technique between 2000 and 2002, The mean follow-up time was 28 months. The time to return to work or complete recovery was found to average 12 days. The rate of functional recovery was 93% (27 hands), and 90% of hands (26 hands) were free of symptoms at the time of publication. According to our study, we conclude that the biportal endoscopic technique is an effective method to attain patient comfort; it is a minimally invasive method with a low complication rate in experienced hands for surgical treatment of carpal tunnel syndrome. Military persons can return to work quickly, without deficits in hand skills, with the use of this technique. [ABSTRACT FROM AUTHOR]
