Abstract
Endoscopic demonstration of the temporal bone and its related structures is a better tool specially for understanding the complex intricacies of the middle ear. In this study we aim to understand the anatomy of the epitympanum/attic with the aid of Otoendoscopy using transmastoid and transattic approaches. Fifty four adult cadaveric temporal bones were dissected at our centre. Transcanal and transmastoid approaches were performed to visualize the middle ear spaces. We could demonstrate Cog, a ridge of bone that extends inferiorly from the tegmen plate just anterior to the head of malleus, epitympanic diaphragm by exploring the three malleal ligamental folds, Prussak's space and its boundaries, pathways of ventilation. Better understanding of the ventilation pathways of the middle ear, restoration of adequate air access in the attic help in better healing and prevent recurrences of diseases. Thus having a three dimentional orientation of the attic and its contents aid the surgeon in performing better surgery and thus provide disease free ear.
