小儿声带沟的研究

Pediatric sulcus vocalis

目的:探讨小儿先天性声带沟的临床特征、诊断、治疗方法。方法:对56例声带沟患儿术前行电子喉镜检查,应用声带沟切开整复术治疗,不附加缝合及用组织或其他外物充填。结果:声带沟占同期嗓音障碍患儿的5.09%(56/1100),5岁以前占80.04%。总有效率96.40%。结论:声带沟在小儿嗓音障碍中不罕见;出生时即有嗓音异常;多呈裂隙型和凹陷型,常有声带表皮样囊肿或息肉共存;声带沟切开整复术不失为一安全、有效、简捷的手术方式。

Objective：To observe the clinic features of the sulcus vocalis in children. Method：From Jan 1995 to April 2005,56 cases of pediatric sulcus vocalis were found by video-laryngoscopy. All received an operation called sulcus vocalis microdissection and vocal cordplasty with four steps： an incision along the superlateral edge of the sulcus; freeing of the mucosa adhering to the vocal ligament ; detachment of the ligamentous fibers; redraping of the mucosa. Result：The total effective rate was 96.4% after surgical treatment. Conclusion： There are 5 % sulcus vocalis among children referred for voice disorders. The sulci are frequently found in association with other laryngeal abnormalities. Sulcus vocalis microdissection and vocal cordplasty might be a rational and effective surgical modality.
