Ear-Canal Cholesteatoma

Ear-canal cholesteatoma is a keratinizing squamous epithelial collection in the external auditory canal, causing canal erosion, conductive hearing loss, and otalgia/otorrhea. It may be congenital or acquired. Treatment: thorough cleaning/removal of keratin debris; topical antibiotics for secondary infection; surgical removal (canalplasty/mastoidectomy) for extensive bone erosion; long-term follow-up to prevent recurrence.

Common Symptoms

Otalagia/otorrhea; conductive hearing loss; canal keratin debris; bone erosion

Causes and Pathogenesis

Accumulation of keratinizing squamous epithelium erodes canal bone.

Treatment

Clean/remove keratin; topical antibiotics; surgery for extensive erosion; follow-up

Preventive Measures
