Abstract

Eustachian tube (ET) dysfunction is known to be a cause for various middle ear diseases. Dynamic slow motion videoendoscopy (DSVE) and impedance audiometry (IA) can both be employed to evaluate ET dysfunction. To assess the role of DSVE and IA for diagnosing ET dysfunction in cases of middle ear disorders. It is a prospective case control study. 102 ears with chronic otitis media were taken as cases and 102 healthy ears as controls. IA and DSVE were performed to assess ET function in both the groups. Sensitivity/ specificity of both the diagnostic tests were evaluated in case and control groups. Out of 102 ET of case group exposed to both tests, 87 were found to have ET dysfunction by DSVE and 80 by IA. Among 102 ET of control group 78 were identified as normal by DSVE while 87 by IA. On applying chi square test in both these groups, the associations were significant. (p value < 0.0001). Patients with grade 2B or higher on DSVE endoscopy had abnormal IA findings, indicating that higher the grade on DSVE, higher the chance of abnormal IA. DSVE and IA are potentially useful tools in evaluation of cases of COM and which provide information regarding functional and pathological factors responsible for ET dysfunction.
