The Le Fort III fracture (transverse fracture) occurs at the level of the skull base, resulting in complete craniofacial separation of the midface from the base of the skull. [ 2 ] [ 3 ] The fracture line extends through the zygomatic arch , the pterygoid plates , the lateral and medial orbital walls , the nasal bones , and the nasal septum .
For example, fractures of the orbital floor or medial orbital wall of the eye can entrap the medial rectus or inferior rectus muscles. [29] In facial wounds, tear ducts and nerves of the face may be damaged. [3] Fractures of the frontal bone can interfere with the drainage of the frontal sinus and can cause sinusitis. [30]
Pneumocephalus and comminuted fracture of the frontal sinus Pneumocephalus is the presence of air or gas within the cranial cavity . It is usually associated with disruption of the skull : after head and facial trauma , tumors of the skull base, after neurosurgery or otorhinolaryngology , and rarely, spontaneously.
A basilar skull fracture typically requires a significant degree of trauma to occur. [1] It is defined as a fracture of one or more of the temporal, occipital, sphenoid, frontal or ethmoid bone. [1] Basilar skull fractures are divided into anterior fossa, middle fossa and posterior fossa fractures. [1] Facial fractures often also occur. [1]
A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma.If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to the underlying structures within the skull such as the membranes, blood vessels, and brain.
The middle cranial foassa technique is most commonly used for the decompression of the facial nerve in Bell's palsy and longitudinal temporal bone fracture. This approach may be useful in the management of patient with schwannomas of cranial nerve 7 and 8, as well as with patient with melkersson-rosenthal syndrome.
The frontonasal duct is a duct through which either frontal sinus drains into the nasal cavity. [2] [3] Each frontal sinus opens into the frontonasal duct by an opening (the opening of frontal sinus or frontal sinus aperture [4]) on the inferomedial part [3] of the floor of the sinus. [4]
When the primary survey is completed, resuscitation efforts are well established, and the vital signs are normalizing, the secondary survey can begin. The secondary survey is a head-to-toe evaluation of the trauma patient, including a complete history and physical examination, including the reassessment of all vital signs. Each region of the ...
