Persistent foramen of Huschke: possible risk factor for otologic complications after arthroscopy of the temporomandibular joint

Oral Surg Oral Med Oral Pathol. 1989 Sep;68(3):267-70. doi: 10.1016/0030-4220(89)90208-9.


Several cases of otologic injury after arthroscopy of the TMJ have been reported. This study describes the persistent foramen of Huschke, an area of incomplete ossification of the tympanic plate of the temporal bone present in some persons. The presence of this foramen may render middle and inner ear structures vulnerable to injury during arthroscopy of the TMJ.
