Second Branchial Anomalies: A Study of 94 Cases.

Ninety-four patients with second branchial anomalies were retrospectively analysed at a tertiary care centre from January 2006 to September 2016 to determine the demographical data and management. Branchial sinus and fistula presented earlier as compared to branchial cyst. The mean age at presentation in case of branchial sinuses, fistulae and cysts was 5.07, 5.79 and 7.31 years respectively. There was preponderance in males as compared to females, more so in bilateral cases. Male to female sex ratio was 2.91:1. The branchial fistulae were the most common type of lesions, followed by the branchial sinuses. The branchial anomalies were more on the right side (65.96%) probably due to right handedness of the population. Only eight patients (8.51%) had bilateral anomalies. Four patients had familial association, it was seen in bilateral cases and they presented earlier than unilateral cases. Early and complete surgical excision is the treatment of choice. Preoperative sinogram/fistulogram and intraoperative methylene blue dye injection is not mandatory for excision of a branchial sinus/fistula. Post-operative wound infection was the most common complication (4.25%).
