The mean age was 57\u2009years, and 13 patients were female. Mean follow\u2010up time was 442\u2009days. Seven patients had posterior glottic stenosis, and 13 had bilateral vocal fold paralysis. Twelve patients developed postoperative complications including granuloma formation (four patients), hospital readmission for dyspnea due to glottic edema (five patients), need for revision surgery (nine patients), or failure to decannulate tracheotomy (five patients). Eight patients had an uncomplicated recovery with improved dyspnea, with two patients with tracheotomies decannulated. Patients with a history of smoking tobacco were more likely to experience complications (\n                      <jats:italic>P<\/jats:italic>\n                      = .035). There were no significant differences in outcomes with respect to history of head and neck radiation or gastroesophageal reflux disease. Steroid injection at the surgical site and postoperative medications did not significantly impact outcomes. With respect to granuloma formation, none of the variables analyzed reached significance.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>History of tobacco use increases complication rates after TPC.
