Vocal cord fixation from posterior glottic stenosis may produce progressive airway obstruction. Treatment involves scar excision with adjunctive procedures on healthy tissue, including arytenoidopexy, arytenoidectomy, cordectomy, and cordotomy. Twenty-five children with posterior glottic stenosis were studied; 6 had vocal cord fixation in the midline and 6 had limited vocal cord abduction. All were tracheotomy-dependent because of posterior glottic stenosis and secondary impairment of vocal cord mobility. All children were decannulated after scar incision and widening of the laryngeal framework with posterior cricoid split and stenting. Cartilage grafting was used in 11 patients to maintain an adequate glottic lumen. Ten regained full vocal cord mobility. One had limited adduction, while another's cords were refixed in the midline. A second procedure in the latter patient resulted in limited abduction. Aspiration did not occur in any of the patients, and the voice results were good. Scar incision with cricoid split, cartilage grafting, and stenting is an excellent method for treating posterior glottic fixation without destroying healthy tissue.
后声门狭窄导致的声带固定可能会引起进行性气道梗阻。治疗方法包括在健康组织上进行瘢痕切除及辅助手术,如杓状软骨固定术、杓状软骨切除术、声带切除术和声带切开术。对25例后声门狭窄患儿进行了研究;其中6例声带中线固定,6例声带外展受限。由于后声门狭窄及继发的声带活动障碍,所有患儿均依赖气管切开。所有患儿在瘢痕切开及通过后环状软骨劈开和支架置入扩大喉框架后均拔除了气管套管。11例患者使用了软骨移植以维持足够的声门腔。10例患者恢复了完全的声带活动度。1例内收受限,另1例患者的声带再次固定于中线。后1例患者再次手术后外展受限。所有患者均未发生误吸,嗓音结果良好。环状软骨劈开、软骨移植和支架置入的瘢痕切开术是一种治疗后声门固定而不破坏健康组织的极佳方法。
