Temporal bone fracture is a relatively rare but significant complication of traumatic head injury. We present a rare and unique case of traumatic temporal bone fracture with middle ear effusion, in a 76-year-old woman, following a fall. Physical examination on presentation was remarkable for a superficial scalp hematoma in the occipital region, without any focal neurological deficits. An initial non-contrast head CT revealed a large posterior scalp hematoma and subtle changes suggestive of artifact vs. hemorrhage within the right temporal lobe. Over two days, she developed a worsening headache, with new hearing impairment and reduced right sided bone-conduction on auditory testing. A repeat head CT confirmed a right hemorrhagic temporal lobe contusion as well as a right mastoid and middle ear effusion. A dedicated temporal bone CT scan was performed, which revealed an acute longitudinal fracture through the right mastoid bone without extension into the middle ear cavity. She was evaluated by neurosurgery, managed symptomatically, and observed closely. Her neurological status remained stable, and she was discharged with planned outpatient follow-up with her primary care provider and the consulting neurosurgeon. This case illustrates sequalae of traumatic temporal bone fracture, as well as the value of clinical history and heightened clinical concern for an occult, easily overlooked region during imaging. 相似文献

Acute head trauma in the emergency room is managed primarily by the trauma surgeon or neurosurgeon. Temporal bone fractures
with the complications of hearing loss and facial nerve paralysis may not be promptly evaluated. The otolaryngologist may
not be consulted until late in the hospitalization. Traditionally, longitudinal fractures have been associated with conductive
hearing loss and transverse fractures with sensorineural hearing loss. The purpose of this study was to correlate the type
of fracture with audiometric findings of hearing loss. We also studied the incidence of facial nerve paralysis and its associated
fracture types.
A total of 2906 head trauma patients admitted to the emergency room from March 1994 to May 1996 were reviewed. All patients
had a head computed tomographic (CT) examination. High-resolution CT of the temporal bones was performed in patients suspected
of having a temporal bone fracture. Temporal bone fractures were found in 48 patients (2%) and were classified as longitudinal,
transverse, or mixed. Audiometry was performed by the Department of Otolaryngology in 23 of the patients with temporal bone
fractures. Patients with longitudinal fractures had conductive hearing loss in 43% and sensorineural loss in 23%. Of patients
with transverse fractures, 57% had conductive hearing loss, and 29% had sensorineural loss. Facial nerve paralysis was found
in 11% of patients. Patients with transverse fractures were found to have facial paralysis in 2 of 11 (18%), whereas those
with longitudinal fractures had paralysis in 3 of 36 (8%).
Our study found conductive hearing loss to be more frequent than sensorineural loss in patients with longitudinal and transverse
fractures. This finding differs from traditional associations. We found the fracture orientation as defined by high-resolution
CT scanning of the temporal bones to be a poor predictor of associated hearing loss. Facial nerve paralysis can occur with
both transverse and longitudinal fractures, and extension of fractures to the geniculate ganglion should be sought on high-resolution
CT scans of the temporal bone. The emergency room physicians should be notified of this potential complication.

Temporal bone fractures and their complications 总被引:5,自引:0,他引:5
Summary A total of 84 patients with 89 fractures of the temporal bone were examined with high resolution CT (HRCT) a few hours to 21 months after the initial trauma. Axial HRCT disclosed 63 longitudinal, 13 transverse, 10 complex and 3 atypical fractures. The diagnosis of a temporal bone fracture was established by axial HRCT in almost every case. However, for the precise topographic analysis of the course of the fracture, additional coronal HRCT proved helpful. The most common, surgically treatable complication of temporal bone fracture is disruption of the ossicular chain. Twenty-three such lesions were demonstrated by combined axial and coronal HRCT; 22 lesions of the facial canal could be demonstrated in 27 patients presenting with facial nerve palsy. The most common site of injury to the facial canal was the region of the geniculate ganglion. The only life-threatening complication of a temporal fracture may be otorhinoliquorrhea. This was present in 9 cases. The most common site of leakage identified was the tegmen tympani. With Metrizamide-HRCT precise localisation of the dural laceration was possible in 7 of these 9 cases. 相似文献

Out of 2,888 blunt head injuries that were treated at the Hermann Hospital Trauma Center of the University of Texas at Houston, only 123 temporal bone fractures were diagnosed in 110 patients. The clinical diagnosis was confirmed with high resolution computerized tomography of the temporal bones. Three main categories of fractures were identified: oblique in 74%, longitudinal in 13% and transverse in 13%. The clinical manifestations included hemotympanum in 83%, cerebrospinal fluid otorrhea in 21% and Battle's sign in 10.6%. One third of the patients had conductive hearing loss, 1/2 had mixed hearing loss and the rest sensorineural loss. On exploration, the most frequent middle ear pathology was incudostapedial joint dislocation. Immediate facial paralysis was observed in 64 patients. Only 11 patients needed facial nerve exploration following signs of denervation, the rest recovered spontaneously. Thirteen patients who had delayed facial paralysis also recovered spontaneously. One third of the patients had persistent unsteadiness 6 weeks following the injury. Other unusual complications encountered include 6 cases of abducent paralysis, 2 cases of trigeminal paralysis and 2 cases of aseptic sigmoid sinus thrombosis. 相似文献

Evaluation of CSF leaks: high-resolution CT compared with contrast-enhanced CT and radionuclide cisternography. 总被引:3,自引:0,他引:3

BACKGROUND AND PURPOSE: Radiologic evaluation of CSF leaks is a diagnostic challenge that often involves multiple imaging studies with the associated expense and patient discomfort. We evaluated the use of screening noncontrast high-resolution CT in identifying the presence and site of CSF rhinorrhea and otorrhea and compared it with contrast-enhanced CT cisternography and radionuclide cisternography. METHODS: We retrospectively reviewed the imaging studies and medical records of all patients who were evaluated for CSF leak during a 7-year period. Forty-two patients with rhinorrhea and/or otorrhea underwent high-resolution CT of the face or temporal bone and then had CT cisternography and radionuclide cisternography via lumbar puncture. The results of the three studies were compared and correlated with the surgical findings in 21 patients. RESULTS: High-resolution CT showed bone defects in 30 of 42 patients (71%) with CSF leak. High-resolution, radionuclide cisternography and CT cisternography did not show bone defects or CSF leak for 12 patients (29%) who had clinical evidence of CSF leak. Among the 30 patients with bone defects, 20 (66%) had positive results of their radionuclide cisternography and/or CT cisternography. For the 21 patients who underwent surgical exploration and repair, intraoperative findings correlated with the defects revealed by high-resolution CT in all cases. High-resolution CT identified significantly more patients with CSF leak than did radionuclide cisternography and CT cisternography, with a moderate degree of agreement. CONCLUSION: Noncontrast high-resolution CT showed a defect in 70% of the patients with CSF leak. No radionuclide cisternography or CT cisternography study produced positive results without previous visualization of a defect on high-resolution CT. CT cisternography and radionuclide cisternography may be reserved for patients in whom initial high-resolution CT does not identify a bone defect or for patients with multiple fractures or postoperative defects. 相似文献

High-resolution CT of temporal bone trauma 总被引:2,自引:0,他引:2
Computed tomographic (CT) findings in 18 patients with temporal bone trauma were reviewed. Eight patients suffered longitudinal fractures of the petrous bone, which were associated with ossicular dislocation in two patients. Transverse fractures were detected in six patients, with a contralateral mastoid fracture in one patient. In four patients, the fractures were restricted to the mastoid region. Of the 14 patients in whom adequate neurologic evaluation was available, seven had a permanent facial nerve or hearing deficit while five suffered at least a transient neurologic deficit related to the temporal bone trauma. Routine head CT (10 mm sections) demonstrated only eight of 19 petrous bone injuries. Clues to such injury included opacification of the mastoid air cells (10 patients), sphenoid sinus (11 patients), external canal and middle ear air space (10 patients), and local pneumocephalus (five patients). Evidence of brain trauma or extraaxial hematoma was seen in 12 patients. In 13 cases, high-resolution CT was also performed, demonstrating temporal bone injuries in all. This latter technique allows rapid and detailed evaluation of temporal bone trauma. Reports of radiographic evaluation of temporal bone trauma tend to deal with a somewhat skewed population, selected on the basis of clinical symptomatology. In a major trauma center equipped with high-resolution CT, it was found that temporal bone fractures may be seen incidentally, or in patients in whom symptomatology related to temporal fracture is obscured by much more serious neurologic compromise. 相似文献
