This study aims to determine the effect of adenotonsillectomy (AT) surgery on the progression of spinal curvature in children with mild sleep-disordered breathing (SDB) and concurrent scoliosis, as well as its potential role in preventing the de novo development of scoliosis in children with SDB.
Age between 6 and 15 years.
Diagnosed with mild SDB, defined as: Obstructive Apnea-Hypopnea Index (OAHI) ≤5 events/hour on a laboratory-based PSG performed within the past 6 months, AND parental report of habitual obstructive breathing symptoms (e.g., snoring, mouth-breathing, witnessed apneas) occurring >3 nights per week on average.
Tonsillar hypertrophy grade ≥2 (on a scale of 0-4) and deemed an appropriate candidate for AT upon ENT evaluation (i.e., no absolute contraindications such as submucous cleft palate).
Has undergone radiographic screening for idiopathic scoliosis at the first clinic visit.
Unwillingness or inability to comply with study procedures.
Plans to relocate outside the study area within 24 months.
Previous tonsillectomy or adenoidectomy.
Recurrent tonsillitis meeting guideline criteria for immediate AT.
