-Abstract-
Background and Objectives : Tonsillar and adenoid hypertrophy is one of the common causes of nasal
Obstruction, mouth breathing, snoring and sleep apnea in children. Tonsillectomy and adenoidectomy (T &
A) could relieve these symptoms but may also cause voice changes after the operation. The aim of this
study was to evaluate the voice changes objectively by nasometric and acoustic rhinometric analyses.
Materials and Methods : Thirty-eight patients who underwent T & A and twenty-two control children
who had no sinonasal or tonsillar hypertrophy problems were selected. A visual analogue scale was used
for determining the subjective nasality changes and nasometric analyses were selected. A visual analogue
scale was used for determining the subjective nasality changes and nasometric analyses were used to
determine the objective nasalance differences. Acoustic rhinometry was used to measure the
nasopharyngeal volume changes and the removed adenoid tissue were directly measured. Data were
collected prior to the operation, and on the second, 7th and 14th days after the operation. Data were
compared and analyzed statistically. Results : The volume of removed adenoid tissue was not statistically
related with the subjective nasality changes which increased significantly after T & A. Nasalance in the
patient group increased significantly after the operation compared to that in the control group. The volume
of nasopharynx increased significantly after adenoidectomy, but it had a minimal statistical correlation
with the removed adenoid tissue. Conclusion : Nasometric and acoustic rhinometric tests can serve as
objective tools for evaluating the subjective nasality changes after T & A.
