Abstract :

Introduction:–The ability to hear is an important sensory function for communication and better quality of life. One of the leading cause of heå loss is acquired disorders like chronic otitis media with cholesteatoma. This study is to know the audiological outcomes with respect to cholesteatoma surgeries at our institute.This will be an objective guide for pre–operative counseling of the patients and also will act as insight into our institute outcomes.

Aim:– To evaluate the Pure Tone audiometry(PTA) outcomes in cholesteatoma surgeries and to observe improvement in pre and post–operative air–bone gap(ABG).

Materials &Methods:– A retrospective study of 50 patients who underwent ear surgeries for cholesteatoma at the Department of Otorhinolaryngology, VIMS, Ballariduring the period Dec 2015 to May 2017.

Result:–Audiological evaluation of patients revealed 86% of the study population to have conductive heå loss and 14% patients had mixed heå loss. The preoperative pure tone average for air conduction of the study population was 35.18dB and and the mean postoperative ABG was 19.5dB with an improvement in mean ABG of 13.39dB with p value of <0.000 suggestive of highly significant association.

The mean improvement in ABG in Intact Canal Wall (ICW)mastoidectomy was 11.78dB whereas It was 14.08dB in Canal Wall Down (CWD)mastoidectomy showing a no statistical significant

Conclusion:– In cholesteatoma there is definitely an improvement of conductive heå loss with surgery, though the primary aim is eradication of disease.
