Conclusion:The modificated epiglottic laryngoplasty was effective surgical method for the patients with glottic carcinoma (T3 category).

改良成形术是治疗声门癌T3病变有效的手术法。

Results All cases did not have radiotherapy, and the voice became clear after about 6 weeks, none had tope-recidivated or lymphaden displaced.

结果所有病例术后未作放射治疗，6周左右嗓音开始清晰，声门区结构保存良好。

14 cases were transglottic carcinoma showing extension of mass across ventriculus larynges, narrowing cavity anterior to throat, and damaging cricoid cartilage and spooncartilage.

跨声门癌14例,表现为较大组织肿物跨越生长,前皮腔受压变窄,环状软骨、勺状软骨破坏。

BACKGROUND: Various investigative tools, including direct visualization with stroboscopy and indirect observation with glottography, have been widely used for the observation of vocal fold vibration.

许多观声带振动的工具，包括影像观的频闪镜以及间接观的声门图仪，均已被广泛地运用于声带振动的观。

Methods Video-stroboscopy was used to reveal the laryngeal cavity and dynamic changes of the vocal fold, and sound spectrograph was used to examine audio frequency, pitch and width.

法用频闪镜显示患者腔全貌和声带的动态变化，用声门分析仪检测并记录患者发声的频率、音调和音域。
