“…We analyzed 21 cases, dating from 2000 until the present, of surgical reconstruction of the TMJ herniation into the EAC. 4,10 These cases mainly reconstructed the bone defect area by placing the implant between the anterior wall of the EAC and the rear of the temporomandibular joint. 4 The surgical approaches could be broken down as follows: 14 preauricular cases (66.7%), 4 transcanal cases (19%), and 3 postauricular cases (14.3%).…”

: 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.

“…However, owing to its rarity, most case reports are confined to delineating one or two cases with successful treatment results upon short-term follow-up. None of the previous studies examined surgical complications or postoperative symptom recurrence, and the average follow-up period was merely 12.7 months (3).…”

Objectives: Although rare in etiology, anterior bony wall defects of the external auditory canal (EAC) accompanied by temporomandibular joint herniation may cause various otologic symptoms. Surgical treatment can be considered based on symptom severity because many previous case reports have highlighted its efficacy. This study aimed to review the long-term results of surgical treatment of EAC anterior wall defect and to suggest a stepwise approach when creating a treatment plan. Methods: We performed a retrospective review of 10 patients who underwent surgical management to address the EAC anterior wall defect and its associated symptoms. Medical records, temporal bone computed tomography scans, audiometry, and endoscopic examination findings were analyzed. Results: The primary repair of the EAC defect was the first to be surgically addressed in most cases, excluding one case with a se-vere combined infection. Of the 10 cases, 3 patients exhibited either postoperative complications or symptom recurrence. Six patients had resolved symptoms consequent to primary surgical repair, and four patients underwent revision surgery undergoing a more invasive procedure, such as canalplasty or mastoidectomy. Conclusion: Primary repair of the anterior wall defect of the EAC seems to be overpromoted for lasting results but is not as promising as previously noted. We therefore propose to create a novel treatment flowchart regarding the surgical treatment of anterior wall defects of the EAC based on clinical experience. Level of Evidence: IV.

Herniation of the temporomandibular joint (TMJ) into the external auditory canal is rare as TMJ and external auditory canal are separated by an anterior bony wall of external auditory canal. The bony defect of the anterior external auditory canal can be caused by trauma, otologic procedure, neoplasm, inflammation and a rare congenital bony defect. Conservative treatment is available if the severity of the symptom is mild or asymptomatic. However, surgical procedure is considered if the patient experiences severe distress. There have been no reported cases of surgical-related complications and recurrence during postoperative follow-up period. Herein we report the very first case of foreign body prolapse involving herniation from TMJ extending into the external auditory canal.
