Prevention of airway complications in thyroplasty patients requiring endotracheal intubation.
Patients who have undergone silicone vocal cord medialization and require additional surgery are at risk for airway complications. There is a narrowed glottic aperture that may be prone to develop postoperative laryngeal edema and prosthesis extrusion. This study was designed to assess the management of this difficult airway and to determine the frequency of postintubation complications. We identified 82 patients who had undergone vocal cord medialization with silicone implants between 1991 and 1995. Seventeen of these patients underwent additional surgical procedures requiring general anesthesia. A retrospective review of these patients' charts was performed to determine the management of the airway and the incidence of postintubation complications. There were no postintubation complications in the 17 patients who were studied. The duration of surgery ranged from 40 minutes to 4 hours 15 minutes. Two patients were ventilated via bronchoscope, and 15 patients were intubated orally. The endotracheal tubes ranged from size 6 to size 9 (median size 8). None of the patients required perioperative steroids. All patients were successfully extubated in the recovery room. No patients required intubation or tracheotomy, and there were no implant extrusions. In this study, the incidence of postintubation airway complications in patients who had undergone previous thyroplasty was minimal. Nevertheless, the potential for airway compromise exists. We recommend preoperative discussion with the anesthesiologist, atraumatic intubation with a small endotracheal tube, and diligent observation for airway compromise.
