This is a prospective cohort study. A total of 30 consecutive subjects diagnosed with otosclerosis and presenting to the otology clinic of Dr. George Zaytoun and Dr. Marc Bassim at the American University of Beirut – Medical Center will be invited to participate in this study. Dr. Maher Kasty will ask his patients, who are diagnosed with otosclerosis, at Rafik Hariri Hospital to come to the otology clinic at AUBMC and participate in the study. While the sample size might seem small, this study is the first of its kind and is intended to be a pilot study.

participate in this study.
While being examined in the pre-admission unit, patients will be offered enrollment in the study where they will undergo an acoustic voice analysis through the OperaVox® application for mobile operating systems. OperaVOX is a validated iOS application that provides objective analysis of voice quality using acoustic parameters (Mat Baki et al., 2015). It also offers user-friendly interface, and novel acoustic voice analysis algorithms (Hughes et al., 2012). The tested parameters are: Habitual pitch, fundamental frequency, Voice Turbulence Index, Noise-to-Harmonic Ratio, shimmer, jitter and formant frequencies. They will then be offered another acoustic analysis simultaneously with their follow-up postoperative audiogram after 1 month using the same method.
