Objective: It was aimed to investigate the role of tonsil ultrasonography(USG) in the diagnosis of pediatric OSAS.
Methods: Before tonsillectomy (±adenoidectomy) for OSAS, all patients tonsil USG and polysomnography (PSG) tests were performed. Tonsil volume was measured preoperatively with the Brodsky tonsil grading scale and by postoperative water displacement test.
Results: In total, 47 patients were included in the study. We observed a positive correlation between tonsil volumes measured by preoperative USG and water displacement test postoperatively. There was a statistically significant correlation between tonsil sizes measured by tonsil USG, PSG AHI and questionnaire scores(p < .05).
Conclusion: Preoperative tonsil USG may be helpful test in children with suspected OSAS.
