Abstract
In medialization laryngoplasty such as thyroplasty type I and arytenoid adduction etc, for intraoperative assessment of vacal cord medialization and voice quality, it is required patient to phonate and surgeon to observe glottis with fiberscope at the appropriate time during the procedure. We performed medialization laryngoplasty under general anesthesia with propofol by target controlled infusion (TCI). Patients were allowed to breath spontaneously. We performed difficult parts and painful parts of surgical procedure under hypnosis. When we discontinued anaesthetizing prior to medialization of the vocal cord, the patient could awake and phonate promptly. We compered laryngeal mask with nasal airway for maintenance of airway. When we observed glottis with fiberscope, in the laryngeal mask cases, a positional adjustment was necessary and mask pushed arytenoid to the median so that there was a possibility that the glottis was not suitable for assessment in those cases. In nasal airway cases, a positional adjustment was unnecessary and the observation of the glottis was easy.
