Abstract
A study was undertaken to determine the voice prognosis in 51 of the 408 patients with unilateral recurrent laryngeal nerve paralysis who had visited the Department of Ear, Nose and Throat at Keio University between 1977 and 1984. The 51 patients were divided into three groups: 18 patients without silicone injection, 15 with a silicone liquid implant, and 18 with a silicone solid implant. Data are provided to show that (1) both types of silicone implant are tolerated by the body and effective in improving voice and that (2) the liquid implant is ultimately absorbed and therefore useful for temporary voice improvement in patients in whom the prognosis for vocal fold paralysis is not known, whereas the solid implant is not absorbed and is therefore effective in long term when recovery can be ruled out.
