Background and objective: Tumor extension is the factor that usually determines the choice of radiotherapy or surgery for head and neck cancers. The choice of surgery carries with it certain specific risks that must be assessed jointly by the maxillofacial surgeon and the anesthetist so that they can agree on the best course of action to choose. We aimed to identify risk factors for complications after major head and neck surgery.
Patients and methods: Retrospective descriptive analysis of data for patients who underwent oncologic head and neck surgery with graft reconstruction. The main candidate predictors gathered from records were age, sex, ASA physical status classification, time under anesthesia, and intra- and postoperative events. The main dependent variables were records of early and delayed complications, time until extubation, and related mortality.
Results: We identified 61 interventions in 56 patients (mean duration of surgery, 9 hours). Early complications developed in 57.4% while they were in the critical care area. Age > or =60 years was associated with longer hospital stays. Short-term mortality was higher in current smokers (P= .01). Survival was significantly higher in patients classified ASA 1 or 2 in comparison with those classified as ASA 3 or 4, in whom long-term mortality was higher (P < .05).
Conclusions: The incidence of postoperative complications was associated with comorbidity and risk behaviors found in this type of patient. We feel that a multidisciplinary medical team should assess the surgical and postoperative care of these patients.
