Foramen tympanicum (FT), or foramen of Huschke, describes an uncommon anatomicvariant of a persistent bony defect connecting the external acoustic meatus to the temporomandibular joint (TMJ). Although rare, it can be associated with significant complications, such as TMJ herniation, salivary gland fistula, infectious or tumoral spread between the external acoustic meatus and the TMJ, or result in inadvertent ear injury during TMJ arthroscopy. To the best of our knowledge, this is the first case report of a symptomatic FT with a full description of computed tomography and magnetic resonance imaging findings. Surgical exploration confirmed the presence of FT with TMJ herniation with subsequent successful closure of the defect obtained.
鼓室孔（FT），即胡施克孔，描述的是一种罕见的解剖变异，为连接外耳道与颞下颌关节（TMJ）的持续性骨缺损。尽管罕见，但它可能伴有严重并发症，如颞下颌关节疝、涎腺瘘、外耳道与颞下颌关节之间的感染或肿瘤扩散，或在颞下颌关节镜检查期间导致意外耳部损伤。据我们所知，这是首例对有症状的鼓室孔进行计算机断层扫描和磁共振成像结果全面描述的病例报告。手术探查证实存在鼓室孔伴颞下颌关节疝，随后成功闭合了缺损。
