구개편도 및 아데노이드 크기와 코골이 소리의 연관성: 음성학적 연구 = Relationship Between Adenotonsillar Size and Snoring Sound: Acoustic Analysis

다국어 초록 (Multilingual Abstract)

Background and Objectives The most common cause of snoring in children is enlargedtonsils and adenoids. However, there is insufficient evidence to determine whether the subjectivemeasurement of tonsil hypertrophy, the most common prevailing method, reflects the actualtonsil size and volume. Therefore, we tried to determine whether the subjective gradingof tonsil size and actual tonsil volume is related, and whether tonsil volume, weight, and adenoidindex are correlated with the acoustic analysis of snoring.
Subjects and Method The study was conducted on 21 children between the ages of 4 and15 who came for tonsillectomy and adenoidectomy due to snoring symptoms. The degree ofadenotonsillar hypertrophy was measured using the Brodsky grading scale and adenoid index.
After tonsillectomy, the volume and weight of resected tonsil were measured. For acousticanalysis, the Praat software was used to determine formant frequency and sound intensity. Alinear regression model and a dummy variable were used to determine the correlation betweenthe quantitative values of tonsil, adenoid and the result of acoustic analysis.
Results The Brodsky tonsil grade tended to match the actual tonsil volume, but it was notstatistically significant (p=0.073). There was no correlation between snoring intensity and actualtonsil volume, weight, and adenoid index. Formant frequency 1 and 2 were statisticallynegatively correlated with the actual tonsil volume (p=0.011, 0.002).
Conclusion The study confirmed that the acoustic analysis of pediatric snoring could be ascreening test to predict tonsil volume and changes in the vocal tract due to tonsil hypertrophy.
