Temporomandibular joint herniation through the foramen of Huschke with clicking tinnitus

초록

Introduction: The foramen of Huschke (FH) is an uncommon anatomical variation of the tympanic portion of the temporal bone. It is located on the anteroinferior aspect of the external auditory canal; extremely rarely, the soft tissues around the temporomandibular joint (TMJ) can herniate through it. Case summary: We report two cases of TMJ herniation through the FH presenting with clicking tinnitus that were treated differently. Discussion: The treatment of TMJ herniation depends on the presenting symptoms and the patient's willingness to undergo surgical correction. If surgical management is chosen, the bone can be obliterated using tragal cartilage and temporalis fascia. (C) 2019 Elsevier Masson SAS. All rights reserved.
