Assessment of depth of jugular bulb From various middle ear structures and Its significance in middle ear surgeriesa Cadaveric morphometric study

Abstract

Objectives: 1. Assessing the depth and distance of the vertical segment of the facial nerve from the jugular bulb. 2. Assessing the depth and distance between the jugular bulb and posterior end of round window niche. Methods: · A one-year study was undertaken and cadaveric dissection was performed on 30 wet mount, formalin-fixed temporal bones. · Evaluation of distance of the jugular bulb apex was recorded from posterior end of the round window niche and vertical segment of the facial nerve. · The results are gathered and assessed based on difficulty of approach and depth of the jugular bulb from these structures.
