[Free flap reconstruction in the head and neck. Indications, technical aspects and outcomes].

INTRODUCTION AND OBJECTIVES The use of microvascular free flaps (MFF) has become a common method of head and neck reconstruction because of its high success rates and better functional results. We report our experience in reconstructing complex defects with MFF. METHODS We analysed a series of 246 patients that underwent reconstruction using MFF in our Department from 1991 to 2013. RESULTS There were 259 interventions performed in 246 patients. The most common reason for surgery was tumour recurrence (46%), followed by primary tumour resection (25%). The hypopharynx (52%) and the craniofacial region (22%) were the most frequently reconstructed sites. The free flaps most commonly used were the radial forearm free flap (41%) and the anterolateral thigh free flap (35%). Overall success and complication rates of 92% and 20% respectively were reported. CONCLUSIONS The microvascular free flap is a reliable and useful tool for reconstructing complex head and neck defects and continues to be the reconstructive modality of choice for these defects.
