説明

In order to evaluate surgery on patients with Reinke's edema, polyp, and nodule, phonatory functions were measured pre- and post-operatively. Three indices were measured in this study: perceptual, acoustic, and aerodynamic. A total of 43 cases of Reinke's edema, 49 cases of polyp, and 16 cases of nodule underwent endolaryngeal microsurgery. The treatment given to the patients consisted of the surgery alone.<BR>Generally, the severity of impairment was greatest with Reinke's edema, then polyp, and finally, nodule. Phonatory functions were most impaired in the same order: in other words, the greater the lesion, the more severe the impairment.<BR>For all the diseases, the mean values of the G, R, B, S scales, APQ, and MPT improved after surgery. In the G, R, and B scales and NNEb for the three disceases, slightly under 50 percent of the patients returned to normal.<BR>The perceptual features of Reinke's edema and polyp seemed to be effectad by the mass of the lesion. In addition, in cases of nodule, hyperfunctional vocal habit remained after surgery, and this is thought to be a causative factor of this disease.<BR>These results demonstrated both the efficacy and limitations of surgery. Further developments in surgical technique and establishment of adequate surgical indications are required.
