P112: RETROSIGMOID TRANS-SUPRAMEATAL APPROACH FOR RESECTION OF TRIGEMINAL SCHWANNOMA WITH MECKEL'S CAVE EXTENSION - PERSPECTIVE FROM A NEW SKULL BASE FACULTY
M. Salman Ali, MD; Fernando Vale, MD; Medical College of Georgia at Augusta University
Linear incision was made for retrosigmoid craniotomy. Cerebrospinal fluid was drained from cerebellomedullary cistern. Using dynamic retraction, tumor was identified in trigeminal nerve with normal fibers spread circumferentially. Cisternal portion removed. Supra-meatal tubercle was drilled, and Meckel’s cave exposed. Gross total resection performed. Patient discharged day after surgery with moderate hypoesthesia in trigeminal distribution which is improving gradually.
