“…4 While HRCT is the standard for evaluating temporal bone fractures, MRI is useful for revealing temporal lobe injuries. 5 The facial nerve is affected in up to 7% of patients with temporal bone fracture. Most injuries of the facial nerve occur in the labyrinthine portion, in the region of the geniculate ganglion, and manifest as nerve contusion, edema and hematoma of the neural sheath and partial or complete nerve transection.…”

<p>Bilateral temporal bone fractures are rare; accounting for 9% to 20% of cases of temporal bone fractures. Clinical manifestations include hearing loss, facial paralysis, CSF otorhinorrhea and dizziness. This is a case report of a patient who presented with bilateral temporal bone fractures. This is a report of a 23-yr-old male who sustained bilateral temporal bone fractures and presented 18 days later with complaints of watery discharge from left ear and nose, bilateral profound hearing loss and facial weakness on the right side. Pure tone audiometry revealed bilateral profound sensori-neural hearing loss. CT temporal bones & MRI scans of brain were done to assess the extent of injuries. The patient underwent left CSF otorrhea repair, as the CSF leak was active and not responding to conservative management. One week later, the patient underwent right facial nerve decompression. The patient could not afford a cochlear implant (CI) in the right ear at the same sitting, however, implantation was advised as soon as possible because of the risk of cochlear ossification. The transcochlear approach was used to seal the CSF leak from the oval and round windows on the left side. The facial nerve was decompressed on the right side. The House-Brackmann grade improved from Grade V to grade III at last follow-up. Patients with bilateral temporal bone fractures require prompt assessment and management to decrease the risk of complications such as meningitis, permanent facial paralysis or hearing loss. </p>

“…Severe fracture and penetration of condyle into the MCF may cause sudden death and is probably not so rare as in the past (Kallal et al, 1977;Pepper and Zide, 1985;Engevall and Fischer, 1992). The presence of this eminence may predispose to brain damage in cases of facial trauma (Jones et al, 2000).…”

Bony eminence on the middle cranial fossa corresponding to the temporomandibular joint

We report a nameless bony eminence over the temporomandibular joint (TMJ) and its possible clinical significance. Forty-two half heads of 21 UK Caucasian cadavers (61-95 years old, mean 84.3 +/- 8.2 years, male:female = 11:10) were used to investigate the surface of the middle cranial fossa (MCF) over the TMJ. The thickness of the bony roof of the glenoid fossa was also measured. A bony eminence over the glenoid fossa was observed in half of the specimens. Some showed a complete oval bulge, which completely reflected the contour of the glenoid fossa. The others showed a bony bulge, which partially reflected that contour. The mean (+/-SD) thickness of the bone in the roof of glenoid fossa was 1.5 +/- 1.2 mm. The mean bony thickness of specimens showing the eminence was 0.8 +/- 0.5 mm, whereas it was 2.3 +/- 1.2 mm in specimens without an eminence. These differences were statistically significant (P < 0.01). The osteological features we describe may be relevant to certain clinical problems. Traumatic dislocation of mandibular condyle, for example, might relate to a weakness of the glenoid fossa.

“…MRI is more useful than CT for diagnosing 95 brain injury following temporal bone fracture. In a recent study, temporal lobe contusion was a frequent finding, seen in 46% of patients who had sustained a fracture of the temporal bone (JONES et al 2000). The authors found MRI was more sensitive than unenhanced CT for demonstrating brain injury and suggest it is useful for pre-operative assessment of temporal lobe damage in patients who require surgical treatment following injury.…”

“…It is impractical to perform MRI in the acute situation. When intracranial injury is suspected, MRI is more useful than CT, and it may have a role to document pre-existing temporal lobe injury and potential morbidity if operative treatment is required (JONES et al 2000). Temporal bone fractures have been classified as longitudinal or transverse with respect to the long axis of the petrous bone (PROCTOR et al 1956).…”
