The bone between the external auditory meatus and temporomandibular joint may be destroyed as a result of canaloplasty or malignant otitis externa. This may lead to herniation of the joint capsule into the external auditory canal. Spontaneous herniation through a foramen of Huschke (bony dehiscence in the anterior wall of the tympanic bone) is rare. We present a case of spontaneous herniation with otorrhea.
