Perioperative Outcomes of Branchial Cleft Sinus Tract Excision in Pediatric Patients Without the Use of Intraoperative Dye

Branchial cleft cysts are pediatric congenital anomalies that can present as sinus tracts to the neck. Intraoperative methylene blue dye with fibrin glue has been suggested as an effective tool for tracking the tract's depth to help definitively excise. In this large retrospective study of 118 patients spanning a decade, we aim to elucidate outcomes of branchial cleft anomaly excision without methylene blue dye. A retrospective review was conducted with patients who received branchial cleft anomaly (BCA) with sinus tract excision at Monroe Carrell Jr. Children's Hospital from June 2012 to June 2022. We collected demographic variables, BCA characteristics, perioperative care variables (ie, prior drainage, imaging, and concurrent procedure), and perioperative outcomes (ie, intra- and post-operative complications). Median and interquartile range (IQR) were calculated for continuous demographic variables, and average and standard deviation (SD) were calculated for sinus tract length. Two-tailed Chi-square or Fisher's exact tests were performed to compare categorical samples where applicable with a statistical significance threshold set a priori at
