Evaluation of Residual Disease Following Transcanal Totally Endoscopic vs Postauricular Surgery Among Children With Middle Ear and Attic Cholesteatoma.

JAMA Otolaryngology - Head and Neck Surgery, 2020
Importance Transcanal totally endoscopic ear surgery (TEES) improves tympanic cavity visibility during cholesteatoma resection but does not readily permit 2-handed surgery, which is possible with a postauricular approach and use of an operating ...

L1CAM-ILK-YAP mechanotransduction drives proliferative activity of epithelial cells in middle ear cholesteatoma.

American Journal of Pathology, 2020
Middle ear cholesteatoma (cholesteatoma) is a chronic otitis media with an enhanced proliferation of epithelial cells. Negative pressure in the middle ear is thought to be an important factor related to the etiology of cholesteatoma.
