Abstract
STUDY OBJECTIVES: Postoperative respiratory complications (PORCs) can occur following supraglottoplasty (SGP) for obstructive sleep apnea. However, there are very limited data on risk factors associated with these complications. This study aims to evaluate the occurrence of PORC in children undergoing SGP and to assess clinical factors and polysomnographic parameters predicting these complications. METHODS: A retrospective study was performed in children with laryngomalacia who underwent SGP with preoperative polysomnography. RESULTS: 400 children who underwent SGP met the criteria for entry into the analysis with a total of 416 surgeries with corresponding preoperative polysomnography. The median age (interquartile range) at the time of polysomnography was 0.4 (0.2, 1.5) years. A total of 96 (23.1%) PORCs were noted. Compared with those without complications, children with PORCs had a higher proportion of congenital heart disease (P < .05), higher median obstructive apnea-hypopnea index (obstructive AHI; median 16.0 vs 11.4 events/h; P < .01), and lower median oxygen saturation (SpO2) (P < .001). The unadjusted odd ratio indicated an increased risk of PORCs in children with congenital heart disease (odds ratio 1.66; P < .05) and those with an obstructive AHI > 10 events/h (odds ratio 2.06; P < .01). Multiple regression analysis demonstrated that an obstructive AHI > 10 events/h was the only independent risk factor for PORCs (P < .05). CONCLUSIONS: In our cohort of children with laryngomalacia undergoing SGP, those with underlying congenital heart disease, higher obstructive AHI, and lower SpO2 were more likely to develop PORCs. Only children with an obstructive AHI > 10 events/h were at significantly increased risk for PORCs following SGP. Preoperative polysomnography is useful in preoperative planning in children undergoing SGP. CITATION: Kanavitoon S, Ngamprasertwong P, Gurbani N, et al.
