The treatment of congenital pyriform sinus fistula: a single-center experience

Retrospective study of 56 congenital pyriform sinus fistula cases comparing open resection (33% recurrence) versus hypothermia plasma cauterization with suspension laryngoscopy (100% success, no complications). 3D imaging improved diagnostic accuracy, with authors proposing minimally invasive cauterization as potential first-line treatment for this rare congenital neck anomaly.
