Twenty-five patients underwent type 1 thyroplasty (external medialization of abducted true vocal cord) during a 2-year period 1986 to 1988) at the University of Iowa. The most common indication for thyroplasty was post-thyroidectomy vocal cord paralysis. Eighteen patients (72%) had either a good or an excellent initial result. Five patients were revised. Postrevision, 21 patients (84%) had achieved either a good or an excellent result. Complications were limited to one case of significant vocal cord edema and another instance of vocal cord hemorrhage. No patient required a tracheotomy. No prosthesis extruded. We feel that phonosurgery has the advantages over traditional Teflon injection of allowing the patient's head to be in a neutral position during the operation; of allowing local anesthesia; of permitting a predictable, graduated end point of the procedure; and of being infinitely adjustable, with preservation of the vocal cord mucosal wave.
1986年至1988年期间，爱荷华大学有25例患者接受了1型甲状成形术（外展真声带的外侧内移术）。甲状成形术最常见的指征是甲状腺切除术后声带麻痹。18例患者（72%）术后初期效果良好或极佳。5例患者进行了翻修手术。翻修术后，21例患者（84%）取得了良好或极佳的效果。并发症仅限于1例严重声带水肿和1例声带出血。无一例患者需要行气管切开术。无假体脱出。我们认为，与传统的聚四氟乙烯注射相比，嗓音外科手术具有以下优势：手术过程中患者头部可保持中立位；可采用局部麻醉；手术终点可预测、逐步调整；可无限调节，同时保留声带黏膜波。
