“…It was observed that hearing efficiency reduces as the stage of OSMF advances. This was in accordance with studies by Devi P et al, 16 Chandran A et al, 17 Swarup N et al, 18 Chaudhary MS et al 19 and Shah M et al 8 In Siddiqui et al study, 14 there was no significant difference (p=0.088) found in hearing loss between OSMF and control group on comparison between both the groups. 14 On correlating different stages of OSMF with types of tympanograms, it was found significant (P value = 0.001) in both and left ears.…”

“…In the present study, Oral Submucous fibrosis predominantly affected males of 3rd and 4th decade of life. According to Siddiqui et al 14 and Shah et al, 8 OSMF mainly affected second and third decades of life with a male predominance. In the present study, Audiometric evaluation of 242 ears in 121 OSMF patients revealed that hearing was normal in 168 ears (69.42%), minimal conductive hearing loss was present 20 ears (8.26%), mild conductive hearing loss was present in 26 ears (10.74%), and moderate conductive hearing loss was evident in 28 ears (11.58%).…”

“…Further, there is always a probability that the biopsy may act as an irritant in a form of mechanical trauma and the biopsy site may heal with scar formation due to decreased vascularity and impaired collagen synthesis in the mucosa, which may worsen the disease condition by further limiting the mouth opening. 7 Although many studies 3,[8][9][10] have been conducted, reporting the fibrosis and hyalinization in the epithelium of oral cavity and pharynx, only few studies 4.5 have been reported regarding its effect on Eustachian tube function and hearing status. Aim of the study was to evaluate hearing status and Eustachian tube function in patients of Oral Submucous Fibrosis and to correlate them with various Groups of the disease.…”

Introduction Oral Submucous Fibrosis (OSMF) in severe cases involves palatal and paratubal muscles of Eustachian tube leading to Eustachian tube dysfunction and hearing disabilities. This study aims to evaluate to evaluate hearing status and Eustachian tube function in patients of Oral Submucous Fibrosis and to correlate them with various groups of the disease. Materials and Methods A Cross Sectional study was carried out in a Tertiary Care Hospital on diagnosed patients of OSMF. Patients with hearing loss due to other middle ear pathologies or previous ear surgeries were excluded. Patients were classified into various Groups depending on the severityof the disease. They were subjected to Pure Tone Audiometry and Impedance Audiometry. Results obtained were statistically analysed. Results A total of 121 patients (242 ears) were included in the study. On Pure Tone Audiometry, minimal hearing loss was found in 20(8.26%) ears while mild and moderate hearing loss was seen in 26(10.74%) and 28(11.58%) ears respectively. On tympanometry, Type B and Type C tympanograms(abnormal) were seen in 36(14.88) and 26(10.74%) ears, respectively. On Eustachian Tube Function Test, out of 242 ears, 67 ears (27.68%) showed Eustachian tube dysfunction. On using Pearson’s chi square test, significant association was found between degree of hearing loss, type of tympanograms and eustachian tube function with various groups of OSMF (p value < 0.05). Conclusion OSMF may affect hearing efficiency and Eustachian tube function as the disease progresses.

Evaluation of hearing deficit in patients with oral submucous fibrosis

et al. 2015

View full text Add to dashboard Cite

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)
