Effect of orbitotomy on surgical freedom in Endoscopic Transorbital Approach (ETOA) to the skull base: An anatomical study.

ABSTRACT:

Introduction

To investigate the angle of attacks and surgical freedom in different extents of orbitotomy for Endoscopic Transorbital Approach to the skull base.

Background

Endoscopic Transorbital Approach is gaining popularity among skull base surgeons over the last decade.The surgery can be performed with or without orbitotomy to increase surgical freedom for deeply seated intracranial lesion.

Study design

This is an anatomical and radiological study in which DICOM data of CT Brain is retrieved and analyzed for 4 types of orbitotomies (Group 1: supraorbital rim with lateral orbital rim resection; Group 2: limited supraorbital rim with lateral orbital rim resection; Group 3: lateral orbital rim resection; Group 4: No orbitotomy) on both sides of 19 patients.
