Abstract

Middle ear tumors are relatively rare, and among them, the diagnoses of middle ear lesions originating from cartilage-like tissue are even rarer. Use of transcanal endoscopic ear surgery (TEES) has increased in recent years because of its advantages, such as clear visual field and minimally invasive procedure. Here, we report a middle ear mass originating from cartilage-like tissue treated with TEES. A 62-year-old woman presented with progressive right-sided hearing loss. A white mass was revealed through the tympanic membrane, and pure-tone audiometry detected a mean 50.0 dB conductive hearing loss. Computed tomography showed a mass in the tympanic cavity. TEES was performed for diagnosis and treatment. A white translucent tumor was observed intraoperatively, and it was completely resected. Histopathological examination confirmed the diagnosis of a mass originating from degenerated cartilage-like tissue. To the best of our knowledge, this is the first study of a middle ear mass originating from cartilage-like tissue treated with TEES. TEES with its clear visual field and precise techniques was beneficial in treating the middle ear lesions circumscribed in the tympanic cavity.

经颅内窥镜耳部手术治疗软骨样组织引起的中耳肿块的病例报告。

中耳肿瘤较为罕见，其中源于软骨样组织的中耳病变更为罕见。近年来，经耳道内窥镜耳部手术（TEES）因其视野清晰、手术微创等优点而得到越来越多的应用。在此，我们报告了一例采用 TEES 治疗的软骨样组织中耳肿块。一名 62 岁的妇女出现了进行性右侧听力损失。通过鼓膜发现一个白色肿块，纯音测听检测出平均 50.0 dB 的传导性听力损失。计算机断层扫描显示鼓室内有肿块。为诊断和治疗进行了 TEES 检查。术中观察到一个白色半透明肿瘤，并将其完全切除。组织病理学检查确诊该肿块源于变性软骨样组织。据我们所知，这是第一例用 TEES 治疗软骨样组织中耳肿块的研究。TEES 具有清晰的视野和精确的技术，有利于治疗鼓室周围的中耳病变。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
