By examination, 56 patients were found congestion and tumefaction in epiglottis lingual surface, 26 patients were found high ball-like swelling in epiglottis, 6 patients had epiglottic vallecula mucosa aryepiglottic plicae, arytenoid cartilage swelling, 14 patients had epiglottic tumefaction, 1 case had laryngeal abscess.

检查见会厌舌面明显充血肿胀56例，会厌高度肿胀似球形26例；伴有会厌谷黏膜、杓会厌皱襞、杓状软骨红肿6例；

Invasion of intralaryngeal muscles and the upper and outer aspects of arytenoid cartilage via paraglottic space was found to be the main cause of hemilaryngeal fixation in these cases.

指出梨状窝癌产生半喉固定的主要原因是癌组织通过声门旁间隙侵犯喉内肌和杓状软骨外上方。

The dynamic follow-up of the movement of the arytenoid cartilage, the reconstruction of the glottis rimae and the changes of the voice were analyzed.

并且对术后声带的活动、声门裂的形态及嗓音变化作了动态观察随访，并应用Dr。

Method: Seven cases with laryngeal carcinoma ( T 3N 0M 0) were treated with secondary total laryngectomy. The arytenoid cartilage of the healthy side and interarytenoid fold were remained. A laryngeal phonatory tube with sphincteral function was constructed with arytenoid cartilage and hypopharyngeal mucosa.

方法：7例喉癌病变范围T3N0M0行次全喉切除术，术中保留健侧的披裂软骨及杓间区粘膜，用披裂软骨与下咽粘膜制作具有括约功能的喉发声管。

Conclusion Subtotal laryngectomy with preservation of arytenoid cartilage is recommended for T 3 laryngeal cancer.

手术的关键是不能损伤杓状软骨及喉返神经,设计好环咽吻合方案.
