Pharyngocutaneous fistulae following total laryngectomy

Postoperative pharyngocutaneous fistula formation is a troublesome complication in head and neck surgery and occurred in 8 out of 53 patients following a total laryngectomy (15%). The incidence falls within the lower range of that reported in the literature (6-66%). Different factors which may influence the formation of fistulae were analysed. Factors which seem to increase fistula formation are previous full dose radiotherapy (Co60), residual carcinoma and surgical technique.
