Voice Change Following Adenotonsillectomy in Pediatric Population: Myth or Reality?—A Pilot Study

Abstract

Modifications in the structure of pharynx following adenotonsillectomy are presumed to cause changes in the voice characteristics of patients. Data on effect of tonsillectomy/adenotonsillectomy on changes in voice among Indian children are sparse. This study was thus conducted to study the effect of adenotonsillectomy/tonsillectomy on childrens' voice. It was a prospective observational study of children aged 4–15 years undergoing tonsillectomy with or without adenoidectomy. Measures of voice were noted preoperatively, 1 and 3 months post-operatively. Subjective evaluation was done using Paediatric Voice Outcome Survey (PVOS) questionnaire administered to participants' parents. Objective evaluation was done by recording and analyzing using PRAAT voice analysis software which is an open-software tool. Statistical analysis was done using the statistical software SPSS 17.0 version. There were 31 children between 4 and 14 years of age 65% being male. Adenotonsillectomy was done in 83.5%. There was statistically significant difference in the subjective scores (PVOS) pre-operatively and 3 month postoperative score (p value = 0.001). However, there was no statistically significant difference between any other pre op and post op parameters. Though the only significant post tonsillectomy voice changes noted was subjective by parents 3 months later, it does raise concern whether this could be a reality and not a myth. Further studies with larger number of patients, including involving the subjective evaluation (PVOS) by another person in addition to patients' parent need to be undertaken to address this issue.
