Spontaneous Herniation of Temporomandibular Joint through the External Auditory Canal

The first case was a 56-year-old female patient, and she applied to our clinic because of itching at the EAC. On physical examination, herniation of the TMJ to the left EAC was detected. On computerized tomography, there was a bony defect at the anterior portion of the left EAC. The second case was a 52-year-old female, and she attended our clinic with sore throat. On routine physical examination, herniation of the TMJ through the left EAC was detected. Both patients were asymptomatic; none of them underwent surgery and follow-up visits were recommended.
