OBJECTIVES: The telovelar approach is a surgical method performed through natural corridors of the brain to access the fourth ventricle. The aim of this study is to assess the results of this approach as well as the role of neuroendoscopy in surgical management of fourth ventricle tumors. MATERIAL AND METHODS: A retrospective study was designed, and a series of 52 consecutive patients (32 male, 20 female) with fourth ventricle tumor undergoing telovelar approach was undertaken. In 10 patients (19 %) with a tumor invading the rostral fourth ventricle, an adjustable angle endoscope was also used to ensure total resection of the tumor. RESULTS: Complete resection was obtained in majority of patients (94 %). 30 patients (57 %) required insertion of an external ventricular drain which was discontinued in all patients after 72 h. 2 patients (4 %) underwent permanent ventriculoperitoneal shunt. The postoperative complications included meningitis (8 %), transient facial nerve paralysis (8 %), transient sixth cranial nerve paralysis (6 %) and transient unilateral absence of the gag reflex (4 %). No patient experienced mutism and there was a mortality rate of 2 % (1 case) in current study. CONCLUSION: In our experience, a high rate of total resection of the fourth ventricle tumors could be achieved with the telovelar approach associated with a low risk of surgical morbidity and mortality. Moreover, the use of an adjustable angle endoscope could be useful in patients with a tumor involving the rostral fourth ventricle to ensure total resection of the tumor and also to minimize the extent of telovelar dissection.
