UNASSIGNED: Twenty children diagnosed with CFBCAs who underwent surgery between December 2018 and June 2022 at our hospital were retrospectively analyzed and classified according to their Work lesion type. The guiding significance of the inferior wall cartilage in the surgical treatment of CFBCAs was summarized by investigating the adjacent relationships of the surgical lesions with the external auditory canal and facial nerve.
UNASSIGNED: Of the 20 patients, 16 were classified as Work type I and 4 as Work type II. The lesions were adjacent to the inferior wall cartilage of the auditory meatus in all children. Work type I lesions were located in the upper lateral aspect and were not adjacent to the facial nerve. Work type II lesions were located in the inferior-medial region of the facial nerve. The lesions were completely resected in all children. One patient experienced recurrence 3 months postoperatively because of a residual endochondral fistula. No patients developed facial paralysis or other complications.
UNASSIGNED: The inferior wall cartilage of the auditory meatus may help to the identify the initial lesion of the CFBCAs and can be regarded as a guiding anatomical structure. These lesions can be completely resected. For resection of Work type II first branchial cleft lesions, the surgical incision can be narrower, and can be precisely positioned with the assistance of endoscope.
■对2018年12月至2022年6月期间在我院接受手术的20名被诊断为CFBCA的儿童进行回顾性分析,并根据其工作病变类型进行分类。通过研究手术病灶与外耳道和面神经的毗邻关系,总结下壁软骨在CFBCAs手术治疗中的指导意义。
■在20名患者中,16个被归类为I型工作,4个被归类为II型工作。所有儿童的病变均与耳道下壁软骨相邻。工作类型I的病变位于上外侧,与面神经不相邻。工作II型病变位于面神经的下内侧区域。所有患儿的病灶均完全切除。一名患者术后3个月复发,原因是软骨内瘘残留。无患者出现面瘫或其他并发症。
■耳道下壁软骨可能有助于识别CFBCA的初始病变,可视为指导解剖结构。这些病变可以完全切除。用于切除II型工作型第一分支裂隙病变,手术切口可以更窄,并且可以在内窥镜的帮助下精确定位。
