RESUMO
Tracheostomy is an efficient and widely used method to secure a patent airway in patients undergoing major oral and maxillofacial oncology operations. The inferiorly based Björk flap technique, through a limited incision, followed by early primary skin closure, has been the preferred method in our unit. Patients who underwent tracheostomy for major oral and maxillofacial oncology operations during the period June 2005 to December 2012 were reviewed. Age, gender, preoperative diagnosis, duration the tracheostomy tube was in situ, tracheostomy-associated complications, and long-term sequelae were evaluated. A total 158 tracheostomies were performed using the same surgical approach in patients aged 18-84 years (median 59, mean 58.2, standard deviation 14.24 years). The time the tracheostomy tube was in situ ranged from 3 to 40 days (median 7, mean 9.0, standard deviation 6.52 days). The complication rate was 5.06% (8/158 patients). A major concern highlighted in previous publications is the risk of surgical emphysema with early closure. In this study, no patients developed surgical emphysema, tracheal fistula, clinical tracheal stenosis, or cosmetically unacceptable scarring of the neck. No patient died of a tracheostomy-related cause. In summary, the Björk flap with early primary closure of the skin by simple sutures provides a safe and easily managed approach, causing minimal postoperative morbidity.
