A Rare Case of Idiopathic Bilateral Medial Canal Fibrosis

Medial canal fibrosis usually occurs as sequelae of known conditions such as trauma, infection, or surgery. Rarely, it occurs without an identifiable cause, hence the term idiopathic medial canal fibrosis. Regardless of the etiology, the reportedly most successful treatment is surgery. A 52-year-old lady presented to us with bilateral reduced hearing and left ear tinnitus. There was no significant history to suggest the possible cause of the symptoms. Clinically, there is the presence of thick solid fibrous in the bilateral ear canal. Audiological examination revealed a conductive hearing loss bilaterally with tympanometry of type B, and imaging was done. She successfully underwent canalplasty following that and is doing well to date. In this paper, we reported a rare case of bilateral idiopathic medical canal fibrosis, and we discuss the causes, diagnosis, and best treatment for this disease.
