OTO: Risk Factors for Posttracheostomy Tracheal Stenosis

This podcast highlights original research published in the October 2018 issue of Otolaryngology–Head and Neck Surgery, the official journal of the American Academy of Otolaryngology—Head and Neck Surgery (AAO-HNS) Foundation. The purpose of this study was to determine the incidence of posttracheostomy tracheal stenosis and to investigate variables related to the patient, hospitalization, or operation that may affect stenosis rates. In conclusion, greater than 10 days of orotracheal intubation prior to tracheostomy and endotracheal tube cuff pressure ≥30 mm H2O were associated with greater rates of subsequent tracheal stenosis. The only patient-related factor associated with tracheal stenosis was obesity. Surgical variables associated with increased rates of subsequent stenosis included placement of a tracheostomy tube size >6, use of percutaneous technique, and failure to create a Bjork flap.   Click here to read the full article.
