First branchial cleft anomalies (FBCAs) are the most infrequent malformations that occur during the development of the branchial apparatus, appearing in less than 8% of all branchial anomalies. Traditionally, they are classified into Work type I and II, depending on their origin. We present a pair of rare FBCAs: a case of a preauricular Work type I cyst with twin fistulae coursing toward the parotid gland and a Work type II cyst of significant dimensions.
