会厌在梨状窝癌切除喉咽及喉功能重建术中的应用

The Application of Epiglottis in The Reconstruction of Laryngopharyngeal and Laryngeal Function After The Resection of Pyrifrom Recess Carcinoma

采用会厌为梨状窝癌切除以后行梨状窝或喉所遗留缺损成形１１例。均为鳞状细胞癌。Ｔ２５例，Ｔ３６例，Ｎ１７侧。观察３年以上者６例，３例存活良好。文中详细介绍了采用会厌成形一侧梨状窝或半喉的操作方法和适应症。作者认为会厌位于喉之前上方，不易为梨状窝癌侵犯，会厌高约３６～３９ｍｍ，宽约２４～２７ｍｍ，并与周围软组织相延续，所以具有利用的可行性。但应当指出：此不能作为首选材料，只能用于颈部皮肌瓣或肌筋膜瓣不能应用时。它比用肩胸皮瓣和胸大肌皮瓣省时省力。

he defect of pyriform recess and larynx after the resection of pyriform recess carcinoma was repairedwith epiglottis in 11 cases. All the patients were squamous carcinoma.6 cases were observed for more than3 years and 3 cases survlved. The technique and the indications were describedin details. The authors belivedthat epiglottis lied Superianterion to the larynx and was not likely to be involved by the carcinoma of pyriform reces The epiglottis was about 36～39mm in height,24 ～27mm in width and linked to soft tissuIt could be used to repair the defects.It was not the material of first choice and was used only after the cervical myocutanous flap or myofascial flap not utilized.Using epiglottis was easier than using pectoralis majormyocutaneous flap.
