There was no sex predilection. The majority of patients presented with a left\u2010sided neck lesion (89.7%). Ten patients presented following prior attempts at the surgery of the PSF at another institution; 8 via open surgery and 2 following endoscopic CO<jats:sub>2<\/jats:sub> laser cauterization; other patients only had a history of repeat incision and drainage\u00a0or antibiotic treatment. The success rate of obliteration of the internal opening was 96.83% after a single treatment without complications. Following reoperation, a successful outcome was achieved in the remaining 4 patients. Length of stay ranged from 10 to 14 days.
