摘要
目的提高特殊类型先天性耳前瘘管的诊断与治愈水平。方法对3例特殊耳前瘘管患者的病历资料进行回顾性分析。结果 1例合并先天性颞骨胆脂瘤同期手术;1例瘘管口隐蔽,术中找到瘘管口彻底切除;1例瘘管长,自耳轮脚伸入外耳道深部,后达乳突表面,行双切口彻底切除。结论先天性耳前瘘管伴有听力下降,术前有必要行颞骨CT检查;手术后是否复发取决于瘘管切除是否彻底、被波及的耳郭软骨及感染灶内的肉芽和瘢痕组织。
Objective To improve the diagnosis and treatment of particular congenital preauricular fistula.Methods A retrospective analysis was made on the clinical data of 3 cases.Results One case,combined with cholesteatoma of the middle ear,was surgically resected at the same time,one case of hidden orificium fistulae was completely removed,and one case in which the fistula arose from the foot of the helix to the deep external auditory canal and the surface of the mastoid process,was completely removed by dual-incision operation.Conclusion Preoperative CT scanning of the temporal bone is required for congenital preauricular fistula accompanied with hearing loss.Recurrence depends on whether the fistula,infected auricular cartilage,granulation and scar tissue are thoroughly removed during the operation.
