AbstractOBJECTIVE: Radiotherapy of the Head and Neck region has adverse effects on normal tissues and causes both acute and long-term complications. Mandibular reconstruction after radiation is technically challenging. The purpose of this study was to investigate the morbidity and mortality of microsurgical reconstruction for mandibular defects after radiotherapy. PATIENTS AND METHODS: We retrospectively reviewed our cases of free flap reconstruction for mandibular defects after radiation. The most common reason for mandibular defects was osteoradionecrosis, followed by tumor recurrence. Major and minor complications after surgery were reviewed and analyzed. RESULTS: The major complications included common carotid artery rupture, aspiration pneumonia, lung infection, arterial and venous thrombosis of the flap, flap loss, chyle leak, and acute respiratory failure. The minor complications were also documented, such as wound infection, delayed healing, and wound dehiscence. One patient died of lung infection three months after successful resuscitation from common carotid artery rupture. The other patient died of acute respiratory failure and cardiac arrest at postoperative day one. CONCLUSIONS: Mandibular reconstruction with free flap after radiotherapy has a considerable morbidity, which may lead to mortality. Careful surgical planning and perioperative care are critical to reduce the morbidity and mortality.
