摘要

目的:本研究旨在探讨儿童外耳道胆脂瘤(EACC)的特征,并描述其在颞骨高分辨率计算机断层扫描(CT)上的影像学表现,以提高原发性EACC的诊断准确性:回顾性分析2017年1月至2022年5月期间在深圳市儿童医院确诊的44例EACC患者的临床病历和CT成像特征。分析临床特征,包括外耳道壁发现、听力损伤、症状和体格检查结果,并与病灶受累程度进行对比。分析了不同类型的 EACC 与不同临床症状发生率之间的相关性,并使用 CT 检查了听力受损程度和骨壁破坏率:EACC的平均发病年龄为(9.02 ± 3.15)岁,右耳EACC的平均发病年龄大于左耳EACC(P 0.05)。出现耳痛和听力损失以及在耳镜检查中发现肉芽组织表明需要进行颞骨 CT 扫描。这种成像模式有助于早期发现 EACC 并对其进行准确分类,从而指导选择适当的手术干预措施,并大大有助于防止听力损伤进一步恶化。

External auditory canal cholesteatoma in children: clinical manifestations.

External auditory canal cholesteatoma in children: clinical manifestations.

Purpose: The purpose of this study was to explore the characteristics of external auditory canal cholesteatoma (EACC) among children and to describe its radiological findings on high-resolution computed tomography (CT) of the temporal bone in order to improve the diagnostic accuracy of primary EACC.

Methods: The clinical records and CT imaging features of 44 patients who were diagnosed with EACC between January 2017 and May 2022 at Shenzhen Children's Hospital were retrospectively reviewed. Clinical features, including external auditory canal wall findings, hearing damage, symptoms and physical examination findings, were analysed against the level of lesion involvement. The correlation between different types of EACC and the incidence of different clinical symptoms was analysed, and the degree of hearing impairment and the rate of bone wall destruction were examined using CT.

Results: The mean age at EACC onset was 9.02 ± 3.15 years, and the mean age at onset for EACC involving the right ear was older than that of EACC involving the left ear (P < 0.05). There were 44 patients (46 ears), including 10 ears with type I EACC, 23 ears with type II EACC, and 13 ears with type III EACC. Conductive hearing loss was the main type of hearing impairment observed among EACC patients. There were differences in types I, II and III EACC in terms of hearing impairment; specifically, there was a significant difference in moderate hearing impairment between type II and type III EACC patients (P < 0.05). The four most common symptoms were otorrhea, otalgia, itching and bleeding. The incidence of itching symptoms was greater in type I EACC than the incidence of otorrhea, and the incidence of otorrhea symptoms in type II and type III EACC was significantly greater than that in type I EACC(P < 0.05). There were no significant differences in the fracture rates of the anterior, posterior, superior or inferior walls of the external auditory canal within or between type II and type III EACC patients (P > 0.05). The failure rate of scute damage was significantly higher in type III EACC patients than in type II EACC patients (P < 0.05).

Conclusion: The presence of otorrhea and hearing loss as well as the identification of granulation tissue during otoscopy suggest the need for a temporal bone CT scan. This imaging modality can aid in the early detection and accurate classification of EACC, thereby guiding the selection of appropriate surgical interventions and greatly assisting in preventing further progression of hearing impairment.
