A rare case of abnormal epithelial migration in the external auditory canal secondary to cotton bud abuse

The outer third of external auditory canal is cartilaginous and contains pilosebaceous glands and hair follicles. The medial two third is bony, and the skin is devoid of these skin appendages and its secretions. It also has outward migratory property which makes the ear self-cleansing. Here we prese...

Sumario:The outer third of external auditory canal is cartilaginous and contains pilosebaceous glands and hair follicles. The medial two third is bony, and the skin is devoid of these skin appendages and its secretions. It also has outward migratory property which makes the ear self-cleansing. Here we present an exceeding rare case of hair in the tympanic membrane causing distressing symptom of scratchy sensation, tinnitus, and otalgia. We hypothesize, it is the distortion of migratory pattern medially due to repeated otitis externa caused by abuse of cotton bud that led to presence of hair in the tympanic membrane.
