The Endoscopic Resection of Sellar and Suprasellar Epidermoid Cyst in a Pediatric Patient: A Case Report and Review of the Literature.

Epidermoid cysts are benign congenital tumors that originate from the ectodermal tissue. The sellar/suprasellar region is an infrequent location for epidermoid cysts and such cases are rarely reported in pediatric patients, as these become symptomatic only when they reach 30 years of age. Surgical intervention is considered the ideal treatment option in patients with suprasellar epidermoid cysts, either via open or endonasal approach.

Large skull osteoblastoma presented as aneurysmal bone cyst (ABC).

Aneurysmal bone cysts (ABCs) are rare benign vascular bony lesions mostly encountered in young patients. These cysts can occur as primary lesions or, less frequently, secondary to other pathologies such as osteoblastomas. Skull ABCs are rare and can extend intracranially, presenting with hydrocephalus and bleeding.

Innovative real CSF leak simulation model for rhinology training: human cadaveric design.

Objective: To study the feasibility of designing a human cadaveric simulation model of real CSF leak for rhinology training.

Method: The laboratory investigation took place at the surgical academic center of Prince Sultan Military Medical City between 2016 and 2017. Five heads of human cadaveric specimens were cannulated into the intradural space through two frontal bone holes.
