Oral submucous fibrosis (OSMF) is a chronic insidious disease of the oral cavity mucosa which often occurs due to areca nut chewing, consumption of spicy foods, autoimmunity and genetic predisposition. Burning sensation in the mouth, intolerance to spicy foods, and increasing restriction of mouth opening owing to oral mucosa fibrosis are all clinical signs of OSMF. Advanced cases of OSMF cause hearing loss by blocking of eustachian tube. The extension of the fibrosis towards nasopharynx results in blockage of the eustachian tube opening at the nasopharynx and cause hearing loss. OSMF reduce the eustachian tube patency and cause conductive hearing loss. Involvement of the palatal muscles in OSMF patient may reduce the patency of the eustachian tube, resulting in conductive hearing loss. OSMF patients need audiological early assessment and tympanogram to detect involvement of eustachian tube and middle ear. Pure tone audiometry is a common audiological test which determines the types, degree and configuration of the hearing impairment. As these audiological tests is non-invasive and less time consuming, so useful to help early detection of hearing loss and appropriate therapeutic intervention. There are very few literatures are available related to OSMF and hearing loss. This review article discusses about the etiopathology, epidemiology, clinical manifestations and management of the OSMF and hearing loss.
