Endoscopic transcanal ear anatomy and dissection.

The authors present a manual of transcanal ear dissection, a completely clinically focused discussion of the goals, steps, and outcomes of endoscopic dissection of the middle ear. From operating station setup through instrumentation and tasks, the reader is presented with detailed technique steps interspersed with observe notes that provide anatomic and technique pearls, such as "by removing the skin of the canal and the epithelial layer of the tympanic membrane (TM), you have largely eliminated the bleeding elements of the external ear and TM".
