“…Psimopoulou et al 15 and Chong and Fan 1 reported TPF following mandibular trauma. The studies conducted by Altay et al 17 and Wood et al 10 reported a similar prevalence of 58% of TPF following mandibular and temporal bone fractures. These studies also insinuate that the presence of condylar fracture should increase suspicion of TPF and be detected using high resolution CT of the temporal bone 10 17 .…”

Although TPF is usually associated with high intensity trauma, its relationship to low intensity trauma cannot be ruled out.…”

“…Second, studies on the frequency of TPF are performed either in cases of temporal bone trauma or mandibular bone fracture, which, again, restrict the trauma population only to such cases. Therefore, the majority of TPF has been reported in association with mandibular fractures or temporal bone fractures or other mid-face fractures 1 2 3 6 10 15 17 . Additional studies, with consideration of all maxillofacial trauma patients, are required in order to prevent overlooking isolated cases of TPF.…”

“…In the literature, TPF has been usually diagnosed using CT 1 2 3 10 17 . However, similar to CT, CBCT allows 3D evaluation of the facial bony structures, with the additional advantages of high spatial resolution, minimum radiation exposure, and minimum slice thickness of 0.2 mm, enabling fine structure and fracture detection 19 .…”

Isolated tympanic plate fracture detected by cone-beam computed tomography: report of four cases with review of literature

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 bony fractures. Cone-beam computed tomography is an investigative three-dimensional imaging modality that can be used to detect fine structures and fractures in maxillofacial trauma. This article presents four cases of isolated tympanic plate fracture diagnosed by cone-beam computed tomography with no evidence of fracture involving other bones and review of the literature.

“…Tympanal bone fracture (TBF) is an uncommon complication of blunt head trauma and is mostly associated with a mandibular or petrous bone fracture [1][2][3][4][5][6][7][8][9][10]. It can lead to several complications, including external auditory canal (EAC) stenosis [2,5,11,12] with conductive hearing loss [8,11].…”

A tympanal bone fracture is an uncommon complication of head trauma and is mostly associated with a mandibular or petrous bone fracture. Upon reviewing the medicolegal literature, we could not find any publications on this topic. Tympanal bone fracture may lead to chronic complications (including external auditory canal stenosis and conductive hearing loss), with an important impact in both the medical and judiciary fields (e.g., chronic disabilities with loss of income). We decided to investigate the prevalence and mechanisms of tympanal bone fractures by means of a retrospective observational study on living victims who underwent head computed tomography after blunt head trauma and clinical forensic investigation at our center. We selected 159 cases of living victims with blunt head trauma (following an assault, traffic accident, or work accident) between January 2016 and December 2020. Re-examination of head imaging revealed 12 cases of tympanal bone fracture. Seven individuals showed cranial fractures involving the petrous bone (on the same side as the tympanal bone fracture). Three individuals had a temporomandibular fracture after a fall with chin impact. Only two victims exhibited an isolated tympanal bone fracture.
