We conducted a study to compare the voice quality after transoral endolaryngeal laser surgery versus anterolateral partial laryngectomy in terms of ability to communicate effectively.
Two groups each of 8 patients were reexamined at least 6 months after either a laser surgical or a partial anterolateral laryngectomy for a T1b or T2 vocal chord carcinoma was performed by the same surgeon. The following examinations were conducted: video-laryngoscopy, video-stroboscopy, phonetogram when reading a standard text or when speaking and shouting, voice load test, respiratory flow measurement, auditive voice rating following the RBH model, and auditive rating of the voice by the patients according to a questionnaire.
A voice disorder with a medium-grade dysphony and an essential limitation of the speaking and shouting voice function and voice quality was detected in both groups of patients. No significant differences were observed in any of the parameters evaluation in both groups of patients.
Both surgical techniques appear to be equivalent in terms of postoperative voice function. However, the tracheotomy was avoided in the patients undergoing laser surgery.
我们开展了一项研究，旨在比较经口喉内激光手术与前外侧部分喉切除术后的语音质量，评估其有效沟通能力。
两组各8例患者，均由同一位外科医生对T1b或T2期声带癌患者进行激光手术或前外侧部分喉切除术后至少6个月进行复查。进行了以下检查：电子喉镜检查、频闪喉镜检查、阅读标准文本或说话及呼喊时的语音图、嗓音负荷测试、呼吸流量测量、根据RBH模型进行的听觉嗓音评级，以及患者根据问卷对嗓音进行的听觉评级。
两组患者均检测出中度发音障碍，说话及呼喊嗓音功能和语音质量存在实质性限制。两组患者在任何参数评估中均未观察到显著差异。
就术后嗓音功能而言，两种手术技术似乎相当。然而，接受激光手术的患者避免了气管切开术。
