Technologic advances have enabled timely acquisition of thin-section images and multiplanar reconstructions such that temporal bone anatomy can be evaluated in great detail, with excellent delineation of fractures. Temporal bone fractures can occur after severe blunt trauma to the head and sometimes involve structures of the ear, causing hearing loss, vertigo, balance disturbance, or facial paralysis. Head Neck Surg. Clinical signs of trauma to the middle cranial skull base include hemotympanum, otorrhea, postauricular hemorrhage (Battle sign), facial palsy, vertigo, and tinnitus. 2004;114 (10): 1734-41.

Temporal bone fracture is suggested by Battle sign (post-auricular ecchymosis) and bleeding from the external auditory canal. Temporal bone fracture is described relative to the long axis of the petrous temporal bone, which runs obliquely from the petrous apex posterolaterally through the mastoid air cells. Blunt trauma to the mastoid or temporal area produces a force that results in a longitudinal fracture. Most fractures are of the mixed type. Br Med J. Betz BW, Wiener MD. Holland BA, Brant-zawadzki M. High-resolution CT of temporal bone trauma. should Figure 2: Battle’s sign that appeared four days after the temporal bone fracture … Temporal bone fracture is usually a sequela of significant blunt head injury. Injuries include rupture of the eardrum and damage to the ossicles (the chain of small bones that connects the eardrum to the inner ear), the cochlea (the organ of hearing), the vestibular apparatus (the organ of balance in the inner ear), or the nerve that controls muscles of the face (facial nerve). Basilar skull fractures most commonly involve the temporal bones but may involve the occipital, sphenoid, ethmoid, and the orbital plate of the frontal bone as well. Temporal bone fracture: evaluation and management in the modern era. The temporal (pink) and sphenoid bones (yellow) make up the major structures of the middle fossa of the basal skull. Fracture of the temporal bone is, by definition, a fracture of the skull base. Sir Prescott G Hewett (1812–1891), an English surgeon, had written a description of this very association previously 2.

Radiographic classification of temporal bone fractures: clinical predictability using a new system. Facial nerve function was normal. As the fracture can sometimes involve the ossicles, inner ear and facial nerve, symptoms such as hearing loss, vertigo, balance disturbance, or facial paralysis may be present. A longitudinal fracture courses along the long axis of the temporal bone, often spar-ing the otic capsule. 6. The anterior fossa consists primarily of the frontal bone (shown in brown), however, most of the frontal bone is covered in Diagram 2 by the maxilla (roof of the mouth, identified by blue).

It is important to note whether fractures involve the otic capsule or brain parenchyma By reference to the long axis of the petrous temporal bone (ie in the plane of the ear canal), 80% of temporal bone fractures are longitudinal (from lateral blows) and 20% transverse (from fronto-occipital trauma) Temporal bone trauma and the role of multidetector CT in the emergency department. 2. 112 (1): 186-8. Ø However there are some clinical and radiological signs which must make us think about temporal bone fracture: • CLINIC SIGNS: Otoliquorrhea, hemotympanum, facial nerve paralysis, Battle's sign 1. A Battle sign, or Battle’s sign, is a bruise that indicates a fracture at the bottom of the skull. Fracture of the petrous temporal bone is usually classified according to the main direction of the fracture plane and/or involvement of the otic capsule. “Battle’s sign” refers to bruising that may appear over the mastoid process four helping to prevent contamination of the or more days after a fracture of the temporal bone has occurred (Figure 2). (1991) Radiology. Battle sign may also be associated with rhinorrhea and bruising over the eyes (raccoon eyes). Temporal bone fractures are classified relative to the long axis of the petrous pyramid. Or it may relate to the pulsations of the underlying superficial temporal artery, marking the time we have left here. She had decreased hearing in the left ear and vertigo. Tubbs RS, Shoja MM, Loukas M, et al. Aside from the fracture lucency itself, which may be subtle on thicker slices or some planes, there may be secondary imaging features that, while less specific, raise concern in the setting of trauma for temporal bone fracture 7: Treatment is based on managing facial nerve injury, hearing loss, vestibular dysfunction, and CSF leakage. Battle’s sign causes Battle sign is prominent when there is a fracture of the petrous temporal bone. 2004;114 (10): 1734-41. Signs and symptoms of a temporal bone fracture include bleeding from the ear canal, tympanic membrane perforation, hearing loss, vertigo, facial paralysis. Other signs of temporal bone fracture include: Post-auricular ecchymosis (termed Battle’s sign”), usually resulting from rupture of the posterior auricular artery secondary to the basal skull fracture Haemotymanum, or other otoscopy signs, including an irregular step in the canal, canal laceration, or tympanic membrane perforation The clinical signs of trauma in temporal bone include: fracture along the roof of the external auditory canal, rupture of the tympanic membrane with otorrhea and otorrhagia, hemotympanum, cerebrospinal fluid leak, hearing loss, facial paralysis, Battle's sign (bruising of the mastoid tip). 4. Otolaryngol. Temporal bone fractures can occur after severe blunt trauma to the head and sometimes involve structures of the ear, causing hearing loss, vertigo, balance disturbance, or facial paralysis. 180 (2): 463-6. fractures involving a single facial buttress, Meyers and McKeevers classification (anterior cruciate ligament avulsion fracture), Watson-Jones classification (tibial tuberosity avulsion fracture), Nunley-Vertullo classification (Lisfranc injury), pelvis and lower limb fractures by region. Temporal bone trauma is frequently encountered in the emergency department. Laryngoscope. Clin. Authors; Librarians; Editors; Societies Battle sign and raccoon eye both typically may appear within 6 to 12 hours to 3 days after the fracture is sustained, and hence are not commonly found during initial ED presentation 11.

The correlation with the gravitational unit, the external and internal auditory tube, and consequently its damage leads to loss of coordination, and acuity of hearing. The skull base fractures more easily when struck from the side, on the thin temporal squamosa, than posteriorly on the thick occipital bone. thoracic, abdominal), so temporal bone fractures become into the background of urgency.

This is largely due to difficulties in assessment and the frequent delays in referral, often as a result of other injuries demanding more immediate attention. Delayed-onset or incomplete facial paralysis almost always resolves with conservative management, including the use of tapered-dose corticosteroids.

Air in the temporomandibular joint fossa: CT sign of temporal bone fracture. In addition to potentially damage to hearing and the facial nerve, associated intracranial injuries, such as extra-axial hemorrhage, diffuse axonal injury and cerebral contusions are common. Battle sign (base of skull fracture) Battle sign is an eponymous term given to mastoid ecchymosis (bruising of the scalp overlying the mastoid process) and is strongly suggestive of a base of skull fracture, most commonly a petrous temporal bone fracture .
