A variation of first branchial cleft anomalies.

First branchial cleft anomalies are considered to be duplications of the external auditory meatus (EAM) and pinna with a sinus that runs parallel to the EAM (Type 1) or with a sinus that runs from an opening in the neck and ends blindly near the cartilaginous EAM (Type 2). In this paper we discuss a young patient that presented with an infected sinus that did not resemble either of the two known types of first branchial cleft anomalies.
