  • Title: Herniation of the temporomandibular joint into the external auditory canal: a complication of otologic surgery.
    Author: Selesnick SH, Carew JF, DiBartolomeo JR.
    Journal: Am J Otol; 1995 Nov; 16(6):751-7. PubMed ID: 8572137.
    Abstract:
    Herniation of the temporomandibular joint into the external auditory canal has been reported as a result of trauma, neoplasia, infection, inflammatory processes, or developmental malformations. This paper reviews the intimate relation of the temporomandibular joint to the temporal bone as well as the literature describing temporomandibular joint herniation into the external auditory canal. Four cases of temporomandibular joint herniation into the external auditory canal resulting from otologic surgery are presented. Their characteristic location, clinical and radiographic findings are described and contrasted to previously reported cases. Despite striking displacement of the temporomandibular joint into the external auditory canal, there were no clinical symptoms referable to this finding. The absence of symptoms distinguished this postoperative etiology of temporomandibular joint herniation from other etiologies mentioned above.
