“…Group D was significantly associated with mild conductive hearing loss, and normal hearing was significantly associated with the control group as compared with any other group in both the right and left ears (P < 0.01; highly significant). These results were in accordance with those of Chaudhary et al (5). Dysfunction of the eustachian tube in OSMF may be due to fibrosis of the palatal muscles, leading to loss of conductive hearing.…”

“…Usually the eustachian tube is closed, but it opens during actions such as swallowing, yawning, or sneezing, thereby permitting the equalization of middle ear and atmospheric pressures (9). The patency and ventilatory function of the eustachian tube may be impaired if any of these muscles is affected by OSMF (5).…”

“…OSMF also leads to difficulty in speech and swallowing, pain in the throat and ears, and a relative loss of auditory acuity (5). Many studies of OSMF have demonstrated progressive degeneration of the underlying musculature, causing impairment of function.…”

Oral submucous fibrosis (OSMF) is a wellrecognized premalignant condition predominantly affecting the oral cavity, but sometimes extending to the pharynx, esophagus or even the larynx. OSMF may lead to stiffness of the oral cavity, resulting in trismus and inability to eat, difficulty with speech or swallowing, pain in the throat and ears, and a relative loss of auditory acuity. To evaluate the hearing deficit in patients with OSMF, we examined a study group comprising 40 patients, and also 10 age-and sex-matched healthy subjects as controls. All of the subjects were evaluated for hearing loss by pure tone audiometry. The OSMF group showed a significant degree of hearing loss relative to the control group. OSMF in advanced stages was significantly associated with mild conductive hearing loss (P < 0.01). The present study revealed a significant association between OSMF and hearing deficit. Involvement of the palatal muscles with OSMF may decrease the patency of the Eustachian tube, leading to conductive hearing loss. Therefore, all patients with OSMF should be evaluated for hearing deficit and advised about appropriate treatment. (J Oral Sci 57, 109-113, 2015)

Objective: To evaluate the hearing efficiency of Oral Submucous Fibrosis (OSF) patients using Pure Tone Audiometry (PTA) and to correlate between the hearing efficiency and clinical stage of OSF. Material and Methods: Twenty-five patients clinically diagnosed as OSF were evaluated for hearing loss using 'PTA'. Patients were grouped as mild cases and severe cases. Mild cases comprised of Group A and B, and severe cases comprised of Group C and D. Patients suffering from the previous hearing were excluded from the study. The data were submitted to statistical evaluation using the Chi-square test. The level of significance was set at 5%. Results: Out of the total patients, 52.4% were diagnosed as mild cases (Group M) OSF and 47.6% as severe cases (Group S). The analysis of the data of mild cases and severe cases revealed a significant association between advancing stages of OSF and hearing loss (p = 0.026). The cases in Group M after otoscopic evaluation demonstrated no visible ear defect. However, 30% of cases in Group S showed retraction of the tympanic membrane. Conclusion: The results indicate an association between stages of OSF and hearing loss. With advancing stages of OSF, there may be involvement of muscles of soft palate namely the levator veli palatine or tensor veli palatine, which may lead to the narrowing of the Eustachian tube leading to a decrease in air conduction demonstrating it as hearing loss of varying degrees depending upon the involvement.

Oral Submucous fibrosis (OSMF) is a chronic insidious disease of oral mucosa that occurs due to areca-nut chewing, consumption of chillies, autoimmunity and genetic predisposition. The disease starts with burning sensation and inability to tolerate spicy foods with gradual reduction in mouth opening due to fibrosis of the oral mucosa. The extension of fibrosis into the naso pharynx leads to reduction in hearing efficiency. As very few studies had been done to evaluate the hearing disability in OSMF patients, this study had been undertaken to prove the same. To evaluate hearing efficiency in patients with Oral Submucous Fibrosis of various grades of severity. Presentation includes 30 patients of osmf with various grades and evaluated for hearing efficacy by audiometry. Hearing threshold was compared in different grades of osmf. The present study revealed a significant association between OSMF and hearing deficit. Involvement of the palatal muscles with OSMF may decrease the patency of the Eustachian tube, leading to conductive hearing loss. Therefore, the protocol for managing OSMF patients should include ENT consultation and treatment for hearing deficit in order to increase the success rate of treatment.
