Surgical Strategy for Dermoid and Epidermoid Tumors of the Posterior Fossa - Experience with 21 Patients
Abstract Objective The aim of this paper is to describe our surgical strategy and technique and to identify the best management for posterior fossa dermoid and epidermoid tumors (PFDETs). Methods We retrospectively identified 21 consecutive patients (11 males and 10 females...
