Abstract
We examined the voice quality of patients with laryngeal carcinoma after oral laser surgery on the basis of the classification proposed by the European Laryngological Society. The classification is defined from Type I to Type V according to the extent of laser resection. The present study included Type I-Type III cases. The parameters of voice function were MPT, PPQ, APQ, and NHR. At the time of this review, the number of cases is still small, but the overall voice function gradually improved. The voice function of Type I and Type II patients improved for almost 3 months after the operation, but Type III cases tended to take a longer time after the operation for the voice to improve.
