Effects of Oral Submucous Fibrosis on Auditory Tube Function: A Case–control Study

  • Ambrish Kumar Bhagwan Mahavir Medica Superspecialty Hospital, Ranchi, Jharkhand, India
Keywords: Impedance audiometry, Middle ear pressure, Oral submucous fibrosis


Background: Oral submucous fibrosis (OSMF) is a precancerous condition, recognized as collagen disease with resemblance
to localized scleroderma. The study is to analyze the middle ear pressure of OSMF patients of various grades of disease.
Materials and Methods: A total of 40 OSMF patients (80 ears) and 40 healthy controls (80 ears) were analyzed for middle ear
pressure by the use of impedance audiometry.
Results: The impedance audiometry test shows statistically significant difference in middle ear pressure of OSMF patients
and control.
Conclusion: The study suggests that the middle ear pressure may be affected by disease and its progression.
