Bilateral keratin horns arising from the tympanic membranes: A case report

February 2, 2015  |  Chu Qin Phua, MRCS, DOHNS; Vikas Malik, FRCS(ORL-HNS); Patrick Zaid Sheehan, FRCS(ORL)

Abstract

A keratin horn is a horn-like projection composed of dense keratotic material. It usually arises in sun-exposed areas of the body. It can be derived from a variety of underlying benign, premalignant, or malignant epidermal lesions. Risk factors associated with malignant change...

Tympanic membrane perforation with squamous epithelial ingrowth

August 28, 2014  |  Danielle M. Blake, BA; Alejandro Vazquez, MD; Senja Tomovic, MD; Robert W. Jyung, MD

The squamous epithelium of the tympanic membrane and external auditory canal exhibits an inherent migration pattern to facilitate the exfoliation of keratinizing squamous cells as part of a natural cleansing mechanism.

Patients classically present with pulsatile tinnitus and a red mass medial to the tympanic membrane. Some patients may have findings of a red mass that blanches with pneumatic otoscopy, called Brown's sign.

February 25, 2013  |  Willis S.S. Tsang, FRCSEd(ORL); Michael C.F. Tong, MD(CUHK); C. Andrew van Hasselt, M Med(Otol)

Extrusion of ossicular prostheses results from postoperative tympanic membrane medialization. The incorporation of cartilage grafting material is recommended to minimize extrusion.
