Free-flap reconstruction for laryngeal preservation after partial laryngectomy in patients with extended tumors of the oropharynx and hypopharynx

Abstract

Partial laryngeal resection often results in major aspiration problems, making larynx preservation during surgical removal of tumors of the oropharynx and hypopharynx impossible. However, free flaps can be used to reconstruct perilaryngeal tissue, thus preserving the larynx and ensuring a better quality of life for patients. We present the results of forearm free-flap reconstruction of the supraglottis in 22 patients who underwent resections of extended squamous cell carcinomas of the oropharynx and hypopharynx. A total of 9 patients had T3 lesions and 13 had T4 lesions. All patients were additionally treated with radiation therapy alone (to 70 Gy) or in combination with chemotherapy (Cisplatin; 5-fluorouracil). The mean follow-up was 2.4 years. In four patients, tracheostomy could be closed. Five patients suffered from severe aspiration, one of whom had to undergo a laryngectomy. Six patients had mild aspiration and 7 patients had no aspiration, but extensive edema made decanulation impossible. A total of 13 patients were free of disease, 4 patients died of disease, 1 patient died as the result of a second primary cancer and 1 patient died of other causes. Three patients are alive with persistent tumor. Although the majority of patients experienced a better quality of life as a result of larynx preservation, aspiration has remained a problem following treatment.
