  • Title: Resection of pontine cavernous malformation through the pontomedullary sulcus.
    Author: Abla AA, Clark AJ, Lawton ML.
    Journal: Neurosurg Focus; 2014 Jan; 36(1 Suppl):1. PubMed ID: 24380516.
    Abstract:
    In this video, we illustrate a right far-lateral craniotomy for resection of a 13-mm cavernous malformation of the pons in a healthy 53-year-old female patient presenting with diplopia and right 6th nerve palsy. The cavernous malformation was surrounded by normal pons, but was within 1 mm of the pontomedullary sulcus. The lesion was exposed from below through a far lateral craniotomy and accessed through the vasoaccessory triangle, superior to olivary nucleus and 12th cranial nerve. The alternative retrosigmoid craniotomy would have involved significant transgression of the middle cerebellar peduncle. The patient had gross-total resection and some temporary increase in her abducens nerve palsy without any complication. The video can be found here: http://youtu.be/8nOnrnTk3Tg .
