complex sinus tract parrallel to the long axis of the RT post auricular sulcus with 2 points of entry

The neck area was prepped and draped in standard
sterile technique. A 15 blade was used to make a skin incision. There was full dissection surrounding the sinus tract and cyst down to the superficial fascia overlying the
sternocleidomastoid muscle as it inserted into the mastoid tip, then onto
the temporalis fascia. The auricle was retracted anteriorly. Dissection
proceeded surrounding the perichondrium on the posterior aspect of auricle, dissection continued down perichondrium, the entire lesion was excised

thank you in advance
