Modified Best-Practice Algorithm to Reduce the Number of Postoperative Videofluoroscopic Swallow Studies in Patients With Type 1 Laryngeal Cleft Repair.

Abstract

There is no consensus as to the timing of videofluoroscopic swallow studies (VFSSs) in determining resolving aspiration after laryngeal cleft repair. There is a growing literature on the effect of radiation exposure in children. To modify a previously published best-practice algorithm based on a literature review and our clinical experience to maintain the quality of care provided after successful type 1 laryngeal cleft repair, while reducing the total number of postoperative VFSSs by 10% or greater. The previously published algorithm was modified by a multidisciplinary group at a tertiary care academic medical center (Massachusetts Eye and Ear) and was prospectively applied to 31 children who underwent type 1 laryngeal cleft repair from January 1, 2013, to February 28, 2015. The number of VFSSs obtained in the first 7 months after surgery was compared with the peer-reviewed literature and with a retrospective cohort of 27 patients who underwent type 1 laryngeal cleft repair from January 1, 2008, to December 31, 2012. The study cohort comprised 31 patients. Their ages ranged from 10 to 48 months, with a mean (SD) age of 23.94 (9.93) months, and 19% (6 of 31) were female. The mean (SD) number of postoperative VFSSs per patient before and after implementation of the algorithm was 1.22 (0.42) and 1.03 (0.55), respectively. The use of the algorithm reduced the number of VFSSs by 0.19 (95% CI, -0.07 to 0.45). This reduction in radiation exposure is equivalent to 1.47 chest radiographs per child per course of care. Surgical success was 87% (27 of 31) compared with our group's previously published success rate of 78% (21 of 27) (absolute difference, 0.09; 95% CI, -0.17 to 0.34). This modified algorithm to help guide decisions on when and how often to obtain VFSSs after type 1 laryngeal cleft repair can limit patients' radiation exposure, while maintaining high surgical success rates.
