Medical complications in total laryngectomy: incidence and risk factors.

The prevention and management of medical complications are important components in the surgical treatment of head and neck malignancies. We retrospectively evaluated the postoperative medical complications in 414 patients who underwent total laryngectomy between 1973 and 1987. The mortality rate was 1.2% (five deaths); while major, nonfatal medical complications occurred in 6.3% (24 of 384 patients)--seven strokes, three myocardial infarctions, two pulmonary emboli, and 12 respiratory failures requiring mechanical ventilation. Elderly patients did not experience more frequent or more severe medical complications, and the overall pattern of complications was different from that of other surgical specialties. Only specific cardiovascular and pulmonary risk factors were associated with these complications. We conclude that medical complications are a significant cause of morbidity in total laryngectomy; a focused preanesthetic risk factor analysis by a medical team familiar with head and neck cancer patients assures prompt identification and management of these complications.
