| Summary: | Background and Objective This study aimed to assess the effectiveness of acoustic pharyngometry by examining the data before and after adenotonsillectomy in children with sleep-disordered breathing (SDB). Methods This prospective, observational study included 29 children (M/F = 17/12, age = 8.69 ± 2.52 years) with SDB who underwent acoustic pharyngometry before and after adenotonsillectomy. Pre- and postoperative acoustic pharyngometry data, such as the oropharyngeal junction area (OPJ), pharyngeal volume (Vp), glottic area (GL), maximal pharyngeal cross-sectional area (Apmax), minimal pharyngeal cross-sectional area (Apmin), and mean pharyngeal cross-sectional area (Apmean), were compared. Results Before surgery, Apmean was measured at 1.75 ± 0.81 cm2 and increased to 2.24 ± 0.89 cm2 after surgery (p < 0.001); this difference was statistically significant. Moreover, OPJ demonstrated statistically significant changes from 1.03 ± 0.62 cm2 to 1.53 ± 0.77 cm2 (p < 0.001); Apmin measured from 0.99 ± 0.51 cm2 to 1.38 ± 0.69 cm2 (p = 0.003); and Vp increased from 14.45 ± 7.05 cm3 to 18.89 ± 7.72 cm3 (p < 0.001) after surgical treatment. Conclusions Acoustic pharyngometry, a non-invasive and reproducible method, effectively reflects upper airway changes before and after adenotonsillectomy in children with SDB and ATH. This underscores its potential as a valuable tool for objectively evaluating upper airway obstruction caused by ATH in children. |
