Prediction of pharyngocutaneous fistula and survival after salvage laryngectomy for laryngohypopharyngeal carcinoma.

This study examined the risk factors of pharyngocutaneous fistula development and survival in 103 patients who underwent salvage laryngectomy. Previous radiotherapy and tracheostomy were the independent variables predictive of post-salvage fistula development, and nodal positivity at salvage was the independent factor predictive of both disease-free survival and overall survival.
