“…7) Abducens nerve palsy is mostly associated with severe head/facial injuries and/or cervical spine fracture. The nerve is thought to be more prone to injury at two sites—dural entry point (during upward displacement) and petrous apex (during downward displacement).…”

“…To our knowledge, there has been only one earlier imaging study reporting bilateral abducens nerve avulsion after head trauma. 7) FIESTA is a heavily T 2 -weighted MR sequence capable of acquiring very thin slices. As it allows reformatting in all three planes, FIESTA is optimal for analyzing the morphologic features of structures next to cerebrospinal fluid-containing spaces like the basal cisterns.…”

Traumatic injuries of the abducens nerve as a consequence of facial and/or head trauma occur with or without associated cervical or skull base fracture. This is the first report on unilateral avulsion of the abducens nerve in a 29-year-old man with severe right facial trauma. In addition, he exhibited mild left facial palsy, and moderate left hearing disturbance. Magnetic resonance imaging (MRI) using fast imaging employing steady-state acquisition (FIESTA) revealed avulsion of left sixth cranial nerve. We recommend thin-slice MR examination in patients with abducens palsy after severe facial and/or head trauma.

Dorsum sellae and bilateral temporal bone fracture associated with bilateral abducens and facial nerve palsy: letter to the editor

Dear Editor:Cranial base fractures are common after head injuries, yet fractures involving the dorsum sellae and both sides of the temporal bone are scarcely seen [4,8]. Cranial base fractures are usually complicated by cranial nerve injuries. However, bilateral traumatic abducens nerve palsy is a very rare clinical condition [7]; bilateral abducens nerve palsy associated with bilateral facial nerve palsy is even rarer and has not been well described in the literature. We recently treated a case of bilateral abducens and facial nerve palsy in a head trauma patient with fractures of the dorsum sellae and bilateral temporal bones.The patient is a 22-year-old male whose head was crushed by an iron pipe while working. He was alert with a GCS score of 15 points when emergency services arrived minutes later. Then he was admitted to the local hospital, and an ordinary head CT scan was performed, which showed pneumocephalus on the left side of the brain. A complete neurologic examination was performed 3 days later by the neurosurgeon, confirming bilateral abducens and facial nerve palsy (Fig. 1). No signs of other types of injuries were seen. A course of steroids and antibiotics was given to minimize the neurologic edema and avoid intracranial infection. Twenty days later the patient was transferred to our hospital since there was no functional improvement of the injured nerves. We performed a high-resolution head CT scan, which demonstrated a fracture of the dorsum sellae. This fracture allowed the dorsum sellae to rotate anticlockwise by approximately 30°from the bottom view. Also a longitudinal fracture of the left temporal bone and oblique fracture of the right one were confirmed (Fig.
