Abstract
Head and neck surgeons are moving away from routine tracheostomy in free-flap reconstruction. We reviewed prophylactic tracheostomy use in patients undergoing oral cavity or oropharynx free-flap reconstruction to identify patient groups who avoided tracheostomy. Secondary aims were to describe complications associated with and without tracheostomy. A retrospective cohort study was undertaken, using a prospectively maintained database. Inclusion criteria was free-flap reconstruction for an oral cavity or oropharyngeal defect, excluding partial or total laryngectomy. Variables collected included demographics, comorbidity, American Society of Anesthesiologists grade, Charlson Comorbidity Index, tumour site and subsite, extent of resection, surgery duration, tracheostomy, complications, return to theatre and re-intubation. A total of 344 head and neck free-flap reconstructions were performed between January 2017 and July 2019. A total of 164 (87.7%) oral cavity and 23 (12.3%) oropharyngeal reconstructions were included totalling 187 free flaps. A total of 107 (57.2%) were males and 80 (42.8%) females, mean age 62.4 years (range 21-89). Of 187 patients, 100 (53.5%) underwent prophylactic tracheostomy at time of reconstruction. Longer operative time (P < 0.001), resection site (P < 0.001), number of subsites resected (P=0.007), segmental mandibulectomy (P=0.04), lip-split (P=0.05), floor of mouth resection (P < 0.001), lingual release (P=0.007), glossectomy (P < 0.001), extent of tongue resection (P < 0.001), extent of hard palate resection (P=0.04), soft palate resection (P < 0.001) and double free-flap reconstruction (P=0.04) were associated with tracheostomy use. A personalized approach to postoperative airway management allowed almost half of our cohort to avoid tracheostomy. In high-volume institutions with the necessary expertise and support, appropriately selected patients may be safely managed without routine tracheostomy.
