This study aimed to evaluate the prevalence of dysphonia in patients with adenotonsillar problems and to demonstrate the impact of tonsillectomy and adenoidectomy (T &amp; A) on their voice postoperatively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Single\u2010institution retrospective study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Subjects were recruited from those children admitted for the purpose of T &amp; A, and all underwent the auditory\u2010perceptual assessment by speech therapists preoperatively. If children demonstrated scores &gt;2 in the G parameter, we performed subjective (pediatric voice handicap index [pVHI], severity, talkativeness scale) and objective (Multi\u2010Dimensional Voice Program) voice analyses preoperatively and 1 and 3 months postoperatively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among the 1,197 patients, 91 (7.6%) patients showed dysphonia with a score &gt;2 in the G parameter preoperatively. The follow\u2010up voice analysis was completed in 51 and 22 patients after 1 and 3 months, respectively. Although there were no significant differences in the amount of speech preoperatively and postoperatively, the average visual analog scale score for dysphonia severity was significantly decreased at postoperative 1 month and postoperative 3 months. The average total pVHI score, jitter, shimmer, noise\u2010to\u2010harmonic ratio, and soft phonation index were significantly decreased at 1 and 3 months postoperatively. Subjective scores given by parents did not correlate with the acoustic parameters; however, the postoperative subjective parameters were significantly correlated with objective parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Voice problems were significantly improved after T &amp; A in the short term and long term.
