The study objectiveis analysis of surgical treatment results of adult patients with tumors of the fourth ventricle and determination of predictors of unsuccessful outcomes.Materials and methods.In the present study we review results of treatment of 33 adult patients with tumors of the fourth ventricle, which were operated via telovelar approach in Federal Neurosurgical Center (Novosibirsk). The most common symptoms included hydrocephalus (54.5 %), cerebellar dysfunction (33.3 %), cranial nerve deficits (30.3 %). The tumor size was more than 40 mm in 22 cases (66.7 %). The brain stem invasion was occurred in 21 cases (63.6 %).Results.23 tumors were removed totally (69.7 %). Hydrocephalus was regressed in 17 cases (94.5 %). Cerebellar mutism did not occur in any patient. Conclusion.Predictors of poor result may be brain stem invasion, non-radical resection of tumor and preoperative hydrocephalus. We suggest, that the preoperative hydrocephalus should not been operated in the most cases of the fourth ventricular tumors.

Fourth ventricular tumors have traditionally been removed via transvermian approaches, which can result in potential dysequilibrium and mutism. The telovelar approach is an excellent alternative to widely expose fourth ventricular tumors without transgressing the cerebellar vermis. This is achieved by opening the cerebellomedullary fissure and incising the tela choroidea and inferior medullary velum, which form the lower half of the roof of the fourth ventricle. In this operative video manuscript, the authors demonstrate microsurgical resection of a fourth ventricular subependymoma arising from the rhomboid fossa via the telovelar approach. The key technical nuance in this video is to demonstrate a gentle and safe technique to identify a dissectable plane to peel the tumor off of the rhomboid fossa using a microspreading technique with fine micro-bayonetted forceps. A gross-total resection was achieved, and the patient was neurologically intact.The video can be found here: https://youtu.be/ZEHHbUGb9zk.

ObjectThe trans lamina terminalis approach (TLTA) has been described as a way to remove third ventricular tumors. The aim of this paper was to analyze the feasible outcomes of TLTA applied to tumors extending into the third ventricle in our institute.MethodsSuprasellar tumors (n = 149) were treated by the extended endonasal approach from September 2019 to December 2020 in Beijing Tiantan Hospital. Eleven of the tumors were treated by TLTA or TLTA via the trans-chiasm-pituitary corridor (TCPC). The surgical technique notes of TLTA were described and indications and outcomes of the approach were analyzed.ResultsThere were 11 patients enrolled in the study, six with papillary craniopharyngiomas, two with adamantinomatous craniopharyngiomas, one with a germinal cell tumor (GCT), one with cavernous malformation and one with chordoid glioma. Four of the patients received a radical resection by TLTA alone, while seven of them received TLTA via the TCPC. Gross total resection was achieved in eight patients (72.7%), and partial resection in three patients (27.3%). Visual function was improved in four of the 11 patients (36.4%), was unchanged in five patients (45.5%), and deteriorated in two patients (18.2%). New-onset hypopituitarism occurred in seven patients (63.3%) and new-onset diabetes insipidus occurred in two patients (18.2%). Electrocyte imbalance were observed in six patients (54.5%) at post-operative week 2. There were no surgery-related deaths or cerebrospinal fluid leaks. Postoperative intracranial infection was observed in one patient (9.1%), and during the follow-up period, tumor recurrence occurred in one patient (9.1%).ConclusionThe expanded TLTA provides a feasible suprachiasm corridor to remove tumors extending into the third ventricle, especially for craniopharyngiomas. Sound understanding of the major strengths and limitations of this approach, as well as strategies for complication avoidance, is necessary for its safe and effective application.
