The tympanic plate is a small part of the temporal bone that separates the mandibular condyle from the external auditory canal. Fracture of this small plate is rare and usually associated with other bony fractures, mainly temporal and mandibular bone. There is a limited amount of literature on this subject, which increases the chance of cases being overlooked by physicians and radiologists. This is further supported by purely isolated cases of tympanic plate fracture without evidence of other… Expand

Insight in to the Awareness of CBCT as an Imaging Modality in the Diagnosis and Management of ENT Disorders: A Cross Sectional Study
The study aims to evaluate the awareness of CBCT as an imaging modality among Ear, nose and Throat (ENT) practitioners and finds that continuing medical education and inclusion in the medical curriculum will increase the scope and awareness about CBCT among ENT fraternity. Expand

Hypocycloida1 tomography demonstrated that longitudinal fractures can involve the anterior and the posterior portions of the petrous bone; an associated fracture of the tympanic part of the temporal bone occurs in two-thirds of all petrous fractures; and combined fractures result in distractive fragmentation of petrousBone.

The frequency of isolated tympanic plate fractures in maxillofacial trauma is low, but it is an important anatomic location and the presence of these injuries should raise suspicion of a concomitant isolated tyMPanic plate fracture. Expand
Tympanic Plate Fractures in Temporal Bone Trauma: Prevalence and Associated Injuries
Tympanic plate fractures are commonly seen on high-resolution CT performed for evaluation of temporal bone trauma and it is important to recognize these fractures to avoid the preventable complication of external auditory canal stenosis and the potential for conductive hearing loss due to a fracture involving the scutum or ossicular chain.

Traumatic Fractures of the Tympanic Plate: A Literature Review and Case Report
Fracture of the tympanic plate resulting from posterior dislocation of the mandibular condyle is an uncommon diagnosis and computerized tomography was used as a diagnostic resource in a conservative therapeutic and clinical controlled one-year study. Expand
Tympanic plate fracture following mandibular trauma.
This work reports four cases of tympanic plate fracture and presents CT images demonstrating the range of injuries seen, with a focus on the posterior dislocation of the mandibular condyle. Expand
Fracture of the tympanic plate with soft tissue extension into the auditory canal resulting from an unfavorable chewing experience.

Mandibular condyle fracture and dislocation into the middle cranial fossa.
In the present case, the dura was covered with temporalis muscle and the glenoid fossa was covered using the fragments of the fractured condyle as an autogenous free bone graft. Expand
Temporal bone trauma and the role of multidetector CT in the emergency department.
Although classifying temporal bone fractures helps physicians understand and predict trauma-associated complications and guide treatment, identifying injury to critical structures is more important for guiding management and determining prognosis than is simply classifyingporal bone fractures into a general category.
