Objective: To demonstrate similar improvement in pediatric sleep-disordered breathing (SDB) as determined by polysomnography (PSG) with microdebrider-assisted partial intracapsular tonsillectomy and adenoidectomy (PITA) versus Bovie electrocautery complete tonsillectomy and adenoidectomy (T&A). Methods: In this retrospective cohort study, 30 children found to have SDB by PSG who have undergone either PITA (15 participants) or T&A (15 participants) as treatment were evaluated with standardized history and physical examination and unattended home overnight PSG. Results: Median change in apnea-hypopnea index (AHI) was 1.7 (-4.9 to 29.8) for the PITA group and 2.3 (-10.9 to 64.1) for the T&A group, although there was substantially more variability in the T&A group. A mixed linear model evaluating the relation of surgical group with change in AHI demonstrated no significant differences in group means (F[1,13]. = 0.31, P= .590) but the variances differed significantly (residual likelihood ratio chi-square. = 5.24, df. = 1, P= .022). Five of 15 (33%) PITA patients and 4 of 15 (27%) T&A patients had postoperative AHI scores of ≤5; this difference was not statistically significant (Fisher exact test P= 1.000). There was no significant interaction or substantial confounding effect of age, sex, race, preoperative tonsil size, preoperative AHI, or body mass index in the model relating surgery type to reduction of postoperative AHI to ≤5. Conclusions: Our study demonstrates no clinically or statistically significant differences in PSG and clinical outcomes between PITA and T&A for treatment of pediatric SDB in otherwise healthy children.
