Lateral plating of the temporal bone: Hemostatic technique for complex transverse fractures of the petrous temporal bone April 2016 DOI: 10.1016/j.tcr.2016.03.009 The fracture also traverses the anterior genu and tympanic segment of the facial nerve bony canal and involves the jugular foramen and the carotid canal. Using this plane, fractures may be classified as follows: longitudinal fractures transverse fractures mixed fractures Otic capsule involvement The mouse open femur fracture model produces typical transverse fracture with normal progression of fracture healing. The average time for bone healing is about 6-8 weeks, but can varies depending upon many factors; Local Factors. Analytical, Diagnostic and Therapeutic Techniques and Equipment 24. . Temporal bone fractures have been classified by orientation with respect to the long axis of the petrous portion of the temporal bone. Complications 13. it is designed to reduce transverse bone fractures; and it holds the bone with sharp, opposing points like a towel clip. The most common complications of temporal bone fractures are facial nerve injury, cerebrospinal fluid (CSF) leak, and hearing loss. Trial reduction was performed. Caused by a lateral force over the mastoid or temporal squama, usually produced by temporal or parietal blows. Minor fractures cause just a crack in the bone while major fractures can completely shatter the bone. Dynamic Compression Bone Clamp for Transverse Fractures Canadian Journal of Plastic Surgery .

They may also be the result of a stress fracture where many microscopic breaks form in the bone from repetitive stress, such as running. The fast component beats away from the fracture site in all directions of the gaze; the intensity of the spontaneous nystagmus is represented by the different lengths of black arrows. Attempt to classify temporal bone fractures for prognostic purposes was made by Ishman [4] based on petrous apex involvement. 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. development of complications for an extended period of time after discharge. Fracture Fixation, Internal Bone Nails Fracture Fixation, Intramedullary Bone Screws Fracture Fixation Bone Plates Traction Treatment Outcome Prospective Studies Retrospective Studies Internal Fixators Casts, Surgical Hip Prosthesis Arthroplasty, Replacement, Hip Prosthesis Failure Bone Wires Reoperation Range of Motion . Cited By ~ 1. . The temporal bone provides structural support for the skull, while protecting the cerebrum of the brain and surrounding membranes. Longitudinal fractures make up 70 to 90% of temporal bone fractures, and transverse fractures make up 10 to 30%. Produces sensorineural hearing loss and vertigo due to involvement of the otic capsule and/or transaction/concussion of 8th cranial nerve. However, numerous studies demonstrated no prognostic value in this classification, with the incidence of true longitudinal fractures rarely occurring, rather an oblique fracture with features of both. Temporal bone fractures are best classified as either otic capsule sparing or otic capsule disrupting-type fractures, as such classification correlates well with risk of concomitant functional complications. Some fractures may have characteristics of both patterns. These fractures normally cross the fallopian canal (of the facial nerve) and otic capsule. good health until three days before death when he fell and fractured the left hip. The temporal bone is the thickest bone in the body, requiring significant force to fracture. According to this concept, most temporal bone fractures are actually oblique, and true longitudinal fractures are rare. Recent publications have emphasized the importance of describing fractures in terms of planes rather than lines. They can happen to any bone in your body, but usually affect longer bones after a trauma like a fall or accident. Examples of occipital condyle fractures.

Mixed fractures have both longitudinal and transverse components. Transverse type Second most common (10% to 20%) type of temporal bone fracture (some authors believe that mixed or complex fractures are more common than either). A transverse temporal bone fracture is much less likely to cause a disruption of the ossicular chain since the fracture line is most commonly medial to the middle ear structures, running from the front to the back. Temporal bone fractures constitute a significant bulk of basilar skull fractures which in-turn are the commonest skull fractures following head injury . The temporal bone is composed of a myriad of tiny structures, including many fissures and canals, that must be distinguished from true fractures.

METHODS: The study design was a retrospective review of eight patients who underwent late decompression of acute facial nerve paralysis due to temporal bone fracture involving the geniculate region. Such high-velocity head injuries carry the risk of significant morbidity or mortality due to injury of the cranial nerves or important vascular structures traversing the temporal bone but also associated traumatic brain injury or poly-trauma. Some fractures may have characteristics of both patterns. In addition, this bone surrounds the middle and inner portions . Three mice at each time point (n = 21) were killed exclusively for RNA isolation and qPCR experiments. Three of the six cases were involved in delayed posttraumatic fatal meningitis. Since many of the clinically observed features could not be simply explained by these frcture types terms like oblique and mixed types have been added. https://doi.org/10.1016/S0385-8146 (74)80017-9 Get rights and content Six cases of transverse temporal bone fracture were studied histologically. Roughly 80% of fractures are classified as longitudinal while 20% are transverse. Quite the opposite: slavery built the. Traditionally, temporal bone fractures are classified as either longitudinal or transverse, depending on their course relative to the long axis of the petrous pyramid. In addition, injury to im- portant structures may result in serious complications such as hear- ing loss, dizziness, imbalance, perilymphatic fistula, cerebrospinal While in high resolution CT of temporal bones of 28 patients, it was visualized line fracture in 20 cases, being 64% (n=18) longitudinal and 7% (n=2) transverse, other findings were: opacification of mastoid 25% (n=7), air in glenoid cavity 14% (n=4), ossicular chains luxation 7% (n=2) and middle ear opacification 4% (n=1).
