The foramen of Huschke (FH) is an uncommon anatomical variation of the tympanic portion of the temporal bone. It is located on the anteroinferior aspect of the external auditory canal; extremely rarely, the soft tissues around the temporomandibular joint (TMJ) can herniate through it.
We report two cases of TMJ herniation through the FH presenting with clicking tinnitus that were treated differently.
The treatment of TMJ herniation depends on the presenting symptoms and the patient's willingness to undergo surgical correction. If surgical management is chosen, the bone can be obliterated using tragal cartilage and temporalis fascia.
Huschke 孔（FH）是颞骨鼓部的一种罕见解剖变异。它位于外耳道的前下侧；极罕见的情况下，颞下颌关节（TMJ）周围的软组织可通过它疝出。
我们报告了两例通过 FH 出现 TMJ 疝出并伴有弹响耳鸣的病例，它们的治疗方法不同。
TMJ 疝出的治疗取决于表现症状和患者接受手术矫正的意愿。如果选择手术治疗，可以使用耳屏软骨和颞肌筋膜来破坏骨。
