目的：评价CO2激光声带切除术治疗早期声门癌患者的嗓音效果。方法：对15例声门型Tis和T1喉鳞癌行CO2激光治疗。评估包括声音感知分析、客观声音评估和视频喉频闪检查，患者对自己的声音进行评价，并完成声音相关生活质量（VR-QOL）问卷。结果与在匹配的对照组中获得的那些进行了比较。结果：大多数患者在感知嗓音分析中表现出不同程度的声音嘶哑，主要是粗糙和呼吸声。与对照组相比，他们的声学评价显示基频略有增加，但无统计学差异，抖动，闪烁和噪声谐波比的值更差，具有统计学意义。至于视频喉频闪镜检查结果，较小范围切除组的结果更好。患者在声音方面对生活质量的影响最小。结论：尽管接受CO2激光声带切除术的患者的声音发生了变化，但功能结果是可以接受的，对生活质量的影响最小。Avaliação da voz em pacientes submetidos à cordectomia com laser de CO2.
AIM: To evaluate voice outcomes in patients with early glottic carcinoma treated by CO2 laser cordectomy. METHOD: 15 patients with glottic Tis and T1 squamous cell carcinoma treated with CO2 laser were analyzed. The assessment consisted of perceptual voice analysis, objective voice evaluation and video-laryngo-stroboscopic exam. In addition, patients rated their voices and completed the Voice related Quality of Life (VR-QOL) questionnaire. The results were compared with those obtained in a matched control group. RESULTS: Most of the patients presented some degree of hoarseness on perceptual voice analysis, mainly rough and breathy voices. Their acoustic evaluation compared with the control group showed a small increase in fundamental frequency, but with no statistically significant difference, and the values of jitter, shimmer and noise to harmonic ratio were worse and statistically significant. As regards to videolaryngo- stroboscopic findings, better results were achieved in the less extensive resection group. Patients have had minimal repercussion in their life quality in respect to voice. CONCLUSIONS: In spite of voice alterations in patients submitted to cordectomy by CO2 laser, functional results are acceptable, with minimal repercussion in their quality of life.
