Endoscopic-Assisted Repair of Spontaneous Temporomandibular Joint Herniation Through a Transcanal Approach.

OBJECTIVE

To report of the presentation, diagnosis, and management of a spontaneous temporomandibular joint (TMJ) herniation.

PATIENTS: A 69-year-old man with a spontaneous TMJ herniation.

INTERVENTIONS: Diagnostic evaluation and surgical approaches.

MAIN OUTCOME MEASURES: Imaging, and medical and surgical treatment outcomes.

RESULTS

At 14 months follow-up, the patient reported improved tinnitus and on examination there was no evidence of a hypertrophic scar or canal stenosis, no recurrence of TMJ herniation, no signs of otorrhea, otalgia; and with normal TMJ function.

CONCLUSIONS

The advantages of repairing spontaneous TMJ herniation through a transcanal approach using oto-endoscopy include a high definition video of surgical field, minimal invasiveness, and good postoperative cosmetic outcome.
