Objective. To demonstrate our experience in treating pyriform fossa sinus tracts (PFST) using a novel technique of endoscopic cauterisation of the pyriform fossa sinus opening combined with injection of sodium carboxymethylcellulose gel (VoiceGel) lateral to the tract to encourage tight closure. Methods. Over a 48-month period, we used this technique on 11 patients who were diagnosed with PFST at BC Children’s Hospital, a tertiary paediatric centre in Vancouver, BC, Canada. Results. The 11 patients included 8 males and 3 females, and mean age at presentation was 69 months (range 22-108 months). Mean time from beginning of symptoms till diagnosis was 15 months (range 12-22 months). Ten PFST were on the left side of the neck and one on the right. Nine patients presented with recurrent neck infections and two had suppurative thyroiditis. All patients had endoscopic cauterisation of their PFST opening combined with injection of carboxymethylcellulose lateral to the sinus tract to cause tract collapse. Mean follow up was 15.8 months (range 8-24). All patients are asymptomatic without recurrence at the last follow-up visit. No post-operative complications were reported. Conclusions. Endoscopic management of paediatric PFST combined with the injection of sodium carboxymethylcellulose gel lateral to the sinus tract appears to be a safe and effec-tive treatment option for PFST.
