Children Undergoing Laryngeal Surgery for Obstructive Sleep Apnea: NSQIP Analysis of Length of Stay, Readmissions, and Reoperations

Laryngeal surgery for congenital laryngomalacia: NSQIP-P analysis of complications

OBJECTIVE

To evaluate predictors of complications in children with congenital laryngomalacia who underwent laryngeal surgery.

METHODS

Multi-institutional retrospective analysis using the American College of Surgeons-NSQIP-P database (2014-2019). CPT code 31541 and ICD-10 code Q35.1 (congenital laryngomalacia) were used to select patients <18 years. Variable predictors included demographics and medical co-morbidities. Main outcomes assessed included total length of hospital stay (LOS), reintubation, reoperation and readmission.

RESULTS

1092 children were identified, 450 (41.1%) females and 642 (58.6%) males, with a mean age of 1.1 years (95% CI 1.0-1.2). Mean LOS was 3.9 days (95% CI 3.3-4.6). Sixteen (1.5%) were reintubated, 30 (2.7%) were readmitted, and 18 (1.6%) were reoperated within 30 days. Thirty-one (2.8%) were still in hospital at 30 days. Regression analysis revealed an increase in LOS for several groups; the largest effect was seen for patients with preoperative ventilator dependence, admission within the first 28 days of life, and those who were discharged to other healthcare facilities (p < .001). Preoperative co-morbidities significantly associated with a higher frequency of reintubation included ventilator dependence (p = .003), history of prematurity (p = .016) and chronic lung disease (p = .041). Children undergoing surgery in the first 28 days of life were 10.16 times as likely to return to the OR for a related reason within 30 days than older children (p = .038).

CONCLUSION

Complications were rare after laryngeal surgery with a postop diagnosis of laryngomalacia. Recognizing pertinent clinical factors can help with risk assessment and management.
