Posterior dislocation of the mandibular condyle into the external ear canal

Tympanic Plate Fractures in Temporal Bone Trauma: Prevalence and Associated Injuries

“…8 Temporal bone fractures involving the tympanic plate (Figs 1 and 2), however, are under-recognized and have received little attention beyond isolated case reports involving mandibular trauma. [8][9][10][11][12][13][14][15] The tympanic plate of the temporal bone is a U-shaped structure forming the anterior wall, floor, and part of the posterior wall of the external auditory canal. The limited literature concerning tympanic plate fracture (TPF) suggests that these types of fractures are uncommon.…”

Management of Bilateral Tympanic Bone Fracture: A Simple Venting Method

“…Bleeding from the external auditory canal is a usual feature. Posterior dislocation of the mandibular condyle can be associated with a fracture of the thin tympanic bone, which forms the anterior wall of the bony EAC wall posterior to the temporomandibular joint (TMJ) 4 . Thus, such injuries may or may not be associated with mandibular fracture or TMJ fracture dislocation 5…”

Maxillofacial trauma patterns associated with external auditory canal fractures: Cone beam computed tomography analysis

“…3 Condylar dislocation is related to the force and direction of trauma, and if the condyle is forced against the tympanic plate of the canal unsupported by bone, then fracture of the plate can occur. [13][14][15][16] Traditionally, multislice computed tomography (MSCT) is used in cases of maxillofacial trauma involving multiple facial bones. [13][14][15][16] Traditionally, multislice computed tomography (MSCT) is used in cases of maxillofacial trauma involving multiple facial bones.…”

“…[8][9][10][11][12] Bleeding from the external auditory meatus due to laceration of the skin and stenosis of the external auditory canal are some clinical findings associated with fracture of the EAC. [13][14][15][16] Traditionally, multislice computed tomography (MSCT) is used in cases of maxillofacial trauma involving multiple facial bones. However, MSCT involves a high dose of ionizing radiation.…”
