Adenoid HypertrophyTonsillar HypertrophyVoice Disorders in Children
Study summary
This prospective study aims to evaluate the effects of adenoidectomy and adenotonsillectomy on voice and speech functions in children. Changes in voice quality and resonance may occur after the removal of adenoid and tonsillar tissues, particularly in pediatric patients with enlarged adenoids or tonsils.
Objective voice assessments, including acoustic, aerodynamic, and nasalance measurements, as well as subjective voice-related quality of life questionnaires, will be performed before surgery and at the first and third months after surgery. The results of this study are expected to help clinicians better inform families about possible voice changes following adenoidectomy and adenotonsillectomy procedures.

Primary outcome measure(s)
Change in Fundamental Frequency (F0) — Preoperative, 1 month postoperative, and 3 months postoperative Fundamental frequency (F0), expressed in Hertz (Hz), will be measured using objective acoustic voice analysis with Praat software. Measurements will be obtained from sustained vowel /a/ recordings and compared between preoperative and postoperative evaluations.
Change in Jitter Percentage — Preoperative, 1 month postoperative, and 3 months postoperative Jitter, expressed as a percentage (%), will be measured from sustained vowel /a/ recordings using Praat software. Preoperative jitter values will be compared with postoperative measurements at the 1st and 3rd months to assess changes in frequency stability after surgery.
Change in Shimmer Percentage — Preoperative, 1 month postoperative, and 3 months postoperative Shimmer, expressed as a percentage (%), will be measured from sustained vowel /a/ recordings using Praat software. Measurements obtained preoperatively will be compared with postoperative values at the 1st and 3rd months to evaluate changes in amplitude stability following surgery.
Change in Harmonics-to-Noise Ratio (HNR) — Preoperative, 1 month postoperative, and 3 months postoperative Harmonics-to-noise ratio (HNR), measured in decibels (dB), will be obtained from sustained vowel /a/ recordings using Praat software. Preoperative and postoperative (1st and 3rd months) values will be compared to assess changes in voice signal quality after surgery.
