This module reviews the anatomy and physiology of the middle ear, mastoid, and Eustachian tube.  Understanding the embryology, anatomy, and physiology allows for improved management of Eustachian tube dysfunction and middle ear disease. In depth knowledge of bony middle ear anatomy is necessary when performing surgery in chronic ears because common landmarks may be eroded by disease or absent from previous surgery. Eustachian tube dysfunction can be difficult to diagnose and manage.  Familiarity with clinical and manometric testing may aid in the assessment. 

This module is designed for the study of temporal bone anatomy.

The anatomically complex temporal bone holds many minute and intricately related structures in its small dimensions. The difficult-to-understand three-dimensional topography of the bone mandates the detailed study of this bone before any surgical endeavours. And knowledge of the embryology of such a complex bone makes it easier to understand the inner intricacies.

Otologic surgery is associated with many unique considerations, one of which is anesthesia principles and technique. Whether implementing general anesthesia, local anesthesia, or a combination of both, a knowledge of the fundamental principles as they relate to surgery of the ear is paramount. The application of these principles allows otologic surgery to be adapted to a variety of indications and surgical settings.
