Abstract
Laryngotracheal separation surgery is a minimally invasive procedure among surgical treatments for intractable aspiration. Postoperative laryngocutaneous fistula is the most frequent complication of this surgery. However, to date there have been few reports of useful treatment for the fistula. Here we report a case in which a laryngocutaneous fistula was reconstructed to compensate for suture failure after laryngotracheal separation surgery, and partial resection of the cricoid cartilage by the Kano method was performed to close it. A 59-year-old man with dysphasia caused by cerebral infarction was referred to our hospital. Laryngotracheal separation surgery was performed to prevent aspiration. At the 14th day after surgery, anastomotic leakage and bleeding occurred and surgical treatment for these complications was performed. The laryngocutaneous fistula was reconstructed because it was difficult to suture the anastomotic leakage at the time. After the wound healed, surgical closure of the fistula by the Kano method was performed and the patient had a good postoperative course. Surgical closure of the larynx by the Kano method is a useful procedure to close a fistula complication after laryngotracheal separation surgery.
