|
External auditory canal (EAC) wall defect may occur due to cholesteatoma, and surgeries forchronic ear diseases, trauma, neoplasm or idiopathic. Conservative treatment is available if theseverity of the symptom is mild or asymptomatic. However, these defects require repairmentnot only to attain relief from intermittent otologic symptoms but also to prevent retractionpockets and sequential cholesteatoma. There have been no reported cases of reconstruction ofEAC wall defect by cartilage with perichondrium and groove of wall defect by drilling. Wemanipulated the conchal cartilage so that it could effectively provide robust reconstruction ofthe canal wall defect. Herein we report a case of EAC reconstruction with mastoidectomy withno further complications.
