Voice Analysis in Post Tonsillectomy Patients.

The main aim of this study was to analyse the change in voice in terms of acoustic parameters and its perceptual impact in patients who have undergone tonsillectomy. A prospective study was conducted in our institution-JSS Hospital and JSS institute of speech and hearing, Mysore for a duration of 1 year (December 2015-December 2016). 50 post tonsillectomy cases were selected randomly and subjected to acoustic analysis. It was inferred that situation of vocal analysis and assessment for the vowels 'a', 'i' and 'u' under the categories hoarse, harsh and breathy remain more or less the same during preoperative stages, first preoperative follow up and the second post operative follow up. It was concluded that tonsillectomy did not appear to change the acoustic features of vowels remarkably. It was assumed that the subject may adjust the shape of the vocal tract to produce consistent speech sound after surgery using auditory feedback.
