Swallowing Outcomes Following Supraglottoplasty: A Retrospective Review

xlomafota13 shared this article with you from Inoreader Swallowing Outcomes Following Supraglottoplasty: A Retrospective Review Via The Laryngoscope Objectives/Hypothesis Determine the incidence of short- and long-term dysphagia in pediatric patients with and without syndromes/neurodevelopmental delay following supraglottoplasty (SGP) at our institution. Study Design Retrospective cohort study. Methods A retrospective cohort study of children ≤18 years old who underwent SGP from 2014 to 2019 was undertaken. Age at surgery, sex, race, insurance, underlying syndromes/neurodevelopmental delay, concurrent surgical procedures, and clinical swallowing assessments were reviewed. Logistic regression was performed to identify factors associated with postoperative feeding difficulties. Time-to-event analysis was performed to assess time to resolution of dysphagia. Results A total of 231 patients were identified. Average age at time of SGP was 13.7 months. Of 231 patients, 88 (38.1%) had a syndrome/neurodevelopmental delay. Of these 231 patients, 112 had a preoperative videofluoroscopic swallow study or fiberoptic endoscopic evaluation of swallowing, of whom 53/112 (47.3%) had dysphagia. After SGP, 138/231 (59.7%) underwent clinical/instrumental swallowing assessments, of whom 95/138 (68.8%) had immediate postsurgical dysphagia. At last follow-up (1 month to 45 months), 15/95 (15.8%) had persistent dysphagia on instrumental assessment, 14/15 of whom had syndromes/neurodevelopmental delay. Time-to-event analysis revealed that for the nonsyndromic cohort, 25% had resolution of dysphagia by 4 months, 50% by 10 months, and 75% by 14 months. Cox proportional hazards regression revealed that the presence of underlying syndromes/neurodevelopmental delay was the only factor predictive of long-term postoperative dysphagia (hazard ratio of resolut ion 0.21 [95% confidence interval 0.096–0.48]). Conclusions While short-term feeding difficulties following SGP in pediatric patients are not uncommon, long-term dysphagia is rare in patients without syndromes/neurodevelopmental delay. These data can be used when counseling caregivers about the risks and benefits of SGP. Level of Evidence 4 Laryngoscope, 2021 View on the web Inoreader. Take back control of your news feed.
