Minimally invasive surgery for pyriform sinus fistula by transoral videolaryngoscopic surgery.
Pyriform sinus fistula is a rare branchial anomaly that manifests as recurrent cervical infection resulting from contamination of the fistula internal orifice in the pyriform sinus. Although open neck surgery to resect the fistula has been recommended as a definitive treatment, identifying the fistula within the scar is difficult and occasionally results in recurrence. Here, we describe a novel transoral surgical technique for pyriform sinus fistula using transoral videolaryngoscopic surgery (TOVS) as a definitive treatment to resect and close the fistula without skin incision. Needle cautery enables fine excision and delicate dissection of the fistula tract. TOVS is a safe, easy, and reliable treatment and is a suitable first line treatment.
