Hearing outcome after surgical intervention in fibrous dysplasia of temporal bone

Abstract

Fibrous dysplasia is a benign disease where all components of normal bone are present, but they fail to differentiate into mature structures. Management of temporal bone fi brous dysplasia is conservative. Surgery usually in the form of canaloplasty is performed in cases of complication like hearing loss, canal cholesteatoma, etc., In this report we would like to give emphasis on the role of mastoid exploration in the treatment of fi brous dysplasia of temporal bone especially in context of hearing results. 2 cases of temporal bone fi brous dysplasia underwent surgical treatment in a tertiary hospital. Hearing of the patient improved signifi cantly in one case whereas there was no auditory benefi t in the other case with inner ear involvement.

Translabyrinthine approach to internal auditory meatus: A retrospective study

“…IAM stenosis may occur primarily without any associated abnormalities (congenital) or it may be secondary to osseous lesions such as osteoma, exostosis, otosclerosis, fibrous dysplasia, Paget's disease or osteopetrosis. [16][17][18][19][20] The present case underwent a translabyrithine approach to IAM with decompression of facial nerve because of the progressive nature of facial nerve paresis. Surgery is indicated when IAM stenosis is associated with symptoms such as hearing loss and facial asymmetry.…”

Fibrous Dysplasia of the Temporal Bone

“…Patients may present with complications such as cholesteatoma (15%) (2,12,14,16,20,28,33), otorrhea (8.8%) (16,22,24), and facial paralysis (5%) (1,18). Patients may present with complications such as cholesteatoma (15%) (2,12,14,16,20,28,33), otorrhea (8.8%) (16,22,24), and facial paralysis (5%) (1,18).…”

“…The middle ear is often secondarily involved after a prolonged period of EAC stenosis, with such patients presenting with complications such as cholesteatoma (15%) (2,12,14,16,20,28,33), otorrhea (8.8%) (16,22,24), and facial paralysis (5%) (1,18). Given reported success rates, it is reasonable to offer surgery (canaloplasty) to restore hearing and prevent complications, such as external ear canal cholesteatoma, in this group of patients.…”
