| Summary: | Introduction: 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. It is a potentially malignant lesion and can transform
into oral cancer.
Aim: To assess the functional impairment of eustachian tube
by audiogram and tympanometry in both ears in stage IV and
stage III OSMF cases.
Materials and Methods: This was a case-control study in
which 30 cases of OSMF, which included 15 stage IV (30 ears),
15 stage III (30 ears) were compared with 15 normal controls.
Results: 1) Stage IV cases showed 76.3% positive audiogram
with 63.3% of cases having Sclerosis of tympanic membrane i.e.
As curve in Tympanogram; 2) 43.3% of Stage III cases showed
positive audiogram with 46.7% of cases having Sclerosis of
tympanic membrane i.e. As curve in tympanogram; 3) 100%
negative audiogram with 100% normal A curve was seen in all
controls.
Conclusion: From this study, it is evident that functions of
Eustachian tube were affected as fibrosis of oral mucosa
progressed. |
