CO2激光在喉部手术后并发声带粘连的相关因素分析及预防

目的　探讨CO2激光喉显微手术后发生声带粘连的影响因素。方法　选择2012年10月～2016年12月我科采用CO2激光治疗219例喉部病变患者作为研究对象，就性别、年龄、病变性质、病变部位、激光功率和术后肉芽增生等相关因素，分析其与声带粘连的关系，并进行统计学分析。结果　219例患者中发生声带粘连31例，发生率为14.16%。术后声带粘连与病变性质、病变部位、激光功率、术后是否有肉芽增生等因素有关。结论　喉部病变CO2激光应根据不同的病变性质及病变部位，采取适当的手术方式和切割功率，术中、术后采取必要的综合措施，有助于减少术后声带粘连的发生。

Analysis of related factors in vocal cord adhesion after CO2 laser laryngeal surgery and prevention

OBJECTIVE To investigate the related factors of vocal cord adhesion after CO2 laser assisted laryngeal surgery.METHODS Clinical data of 219 patients who received CO2 laser assisted laryngeal surgery in our department from October 2012 to December 2016 were analyzed retrospectively.Correlation analysis of the vocal cord adhesion with patient's gender, age, lesion nature, lesion location,type of operation,laser power, and postoperative granulation hyperplasia were carried out. RESULTS Of the 219 cases, vocal cord adhesion occurred in 31 cases, accounted for 14.16%. The vocal cord adhesion were associated with the lesion nature, lesion location, the laser power, postoperative granulation hyperplasia (P<0.05). CONCLUSION According to the related factors, the appropriate surgical procedure and cutting power, perioperative measures can help to reduce the occurrence of postoperative vocal cord adhesion.
