Herniation of the temporomandibular joint (TMJ) into the external auditory canal (EAC) is rare. The TMJ and EAC are separated by the anterior bony wall of the EAC. Such a defect can be caused by trauma, infection, neoplasm, inflammation, and in rare cases, congenital bony defects. If asymptomatic or mildly symptomatic, supplemental treatment is primarily given, but if the symptoms are severe enough that the patient regularly feels discomfort, surgical procedure is considered. To our knowledge there are no reports about surgery-related complications and recurrence during the postoperative follow-up period for TMJ herniation in English literature. Here, the authors report the first case of implant protrusion after TMJ herniation surgery along with a literature review.
颞下颌关节（TMJ）疝入外耳道（EAC）的情况较为罕见。颞下颌关节和外耳道由外耳道的前骨壁分隔。这种缺损可能由创伤、感染、肿瘤、炎症引起，在极少数情况下，也可由先天性骨缺损导致。如果无症状或症状轻微，主要给予补充治疗，但如果症状严重到患者经常感到不适，则考虑进行手术。据我们所知，英文文献中尚无关于颞下颌关节疝手术后随访期间手术相关并发症及复发情况的报道。在此，作者报告了颞下颌关节疝手术后植入物突出的首例病例，并进行文献综述。
