Branchial apparatus consists of six pairs of mesodermal arches. Invagination of endoderm from inside and ectoderm from outside are known as pharyngeal pouch and branchial clefts respectively. Incomplete fusion of these structure lead to formation of branchial sinus/ fistula. Anomoly of second arch is commonest and manifests as Branchial sinus. We present such a case in a 18 years old boy.
