Free flap reconstructions in the management of oral and pharyngeal cancer.

Abstract

Fifty patients who had undergone microvascular free flap reconstruction of the oral cavity or pharynx for malignancy between 1989 and 1995 were retrospectively analysed to find factors predicting postoperative complications and outcomes. The mean follow-up time was 2.6 years. More than half (26/50) of the patients had a stage IV malignancy and 10 patients had a recurrent tumour. The overall flap success rate, with 2 flap losses, was 96%. Postoperative medical complications occurred in 29/50 (58%) cases. The recipient site of 10/50 (20%) flaps required re-exploration. Mortality was 2%, with 1 death occurring within 30 days. The mean survival rate after the microvascular operation was 1.6 years, and the 3- and 5-year survival rates were 42% and 23%, respectively. Patients with an oropharyngeal tumour seemed to have the best prognosis and those with a hypopharyngeal tumour the poorest. Men had a threefold greater risk of dying within < 1 year postoperatively compared with women. Tumour stage was the strongest attribute influencing survival. The risk of death after the microvascular procedure increased 2.8-fold when the stage advanced from II to III or from II to IV. None of the tested variables alone could predict complications.
