Traumatic injury to the abducens, or sixth, cranial nerve. Injury to this nerve results in lateral rectus muscle weakness or paralysis. The nerve may be damaged by closed or penetrating CRANIOCEREBRAL TRAUMA or by facial trauma involving the orbit.
The 6th cranial nerve which originates in the ABDUCENS NUCLEUS of the PONS and sends motor fibers to the lateral rectus muscles of the EYE. Damage to the nerve or its nucleus disrupts horizontal eye movement control.
Diseases of the sixth cranial (abducens) nerve or its nucleus in the pons. The nerve may be injured along its course in the pons, intracranially as it travels along the base of the brain, in the cavernous sinus, or at the level of superior orbital fissure or orbit. Dysfunction of the nerve causes lateral rectus muscle weakness, resulting in horizontal diplopia that is maximal when the affected eye is abducted and ESOTROPIA. Common conditions associated with nerve injury include INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; ISCHEMIA; and INFRATENTORIAL NEOPLASMS.
Injuries to the PERIPHERAL NERVES.
A syndrome associated with defective sympathetic innervation to one side of the face, including the eye. Clinical features include MIOSIS; mild BLEPHAROPTOSIS; and hemifacial ANHIDROSIS (decreased sweating)(see HYPOHIDROSIS). Lesions of the BRAIN STEM; cervical SPINAL CORD; first thoracic nerve root; apex of the LUNG; CAROTID ARTERY; CAVERNOUS SINUS; and apex of the ORBIT may cause this condition. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp500-11)
An irregularly shaped venous space in the dura mater at either side of the sphenoid bone.
A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.
The dense rock-like part of temporal bone that contains the INNER EAR. Petrous bone is located at the base of the skull. Sometimes it is combined with the MASTOID PROCESS and called petromastoid part of temporal bone.
Disorders of one or more of the twelve cranial nerves. With the exception of the optic and olfactory nerves, this includes disorders of the brain stem nuclei from which the cranial nerves originate or terminate.
The 4th cranial nerve. The trochlear nerve carries the motor innervation of the superior oblique muscles of the eye.
A dull or sharp painful sensation associated with the outer or inner structures of the eyeball, having different causes.
Paralysis of one or more of the ocular muscles due to disorders of the eye muscles, neuromuscular junction, supporting soft tissue, tendons, or innervation to the muscles.
The 3d cranial nerve. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation. The motor fibers originate in the oculomotor nuclei of the midbrain.
A nerve which originates in the lumbar and sacral spinal cord (L4 to S3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the TIBIAL NERVE and the PERONEAL NERVE.
The muscles that move the eye. Included in this group are the medial rectus, lateral rectus, superior rectus, inferior rectus, inferior oblique, superior oblique, musculus orbitalis, and levator palpebrae superioris.
Benign and malignant neoplasms that arise from one or more of the twelve cranial nerves.
Dysfunction of one or more cranial nerves causally related to a traumatic injury. Penetrating and nonpenetrating CRANIOCEREBRAL TRAUMA; NECK INJURIES; and trauma to the facial region are conditions associated with cranial nerve injuries.
Fractures which extend through the base of the SKULL, usually involving the PETROUS BONE. Battle's sign (characterized by skin discoloration due to extravasation of blood into the subcutaneous tissue behind the ear and over the mastoid process), CRANIAL NEUROPATHIES, TRAUMATIC; CAROTID-CAVERNOUS SINUS FISTULA; and CEREBROSPINAL FLUID OTORRHEA are relatively frequent sequelae of this condition. (Adams et al., Principles of Neurology, 6th ed, p876)
The 5th and largest cranial nerve. The trigeminal nerve is a mixed motor and sensory nerve. The larger sensory part forms the ophthalmic, mandibular, and maxillary nerves which carry afferents sensitive to external or internal stimuli from the skin, muscles, and joints of the face and mouth and from the teeth. Most of these fibers originate from cells of the TRIGEMINAL GANGLION and project to the TRIGEMINAL NUCLEUS of the brain stem. The smaller motor part arises from the brain stem trigeminal motor nucleus and innervates the muscles of mastication.
A general term most often used to describe severe or complete loss of muscle strength due to motor system disease from the level of the cerebral cortex to the muscle fiber. This term may also occasionally refer to a loss of sensory function. (From Adams et al., Principles of Neurology, 6th ed, p45)
Diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. With a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. Commonly associated conditions include neoplasms, CRANIOCEREBRAL TRAUMA, ischemia (especially in association with DIABETES MELLITUS), and aneurysmal compression. (From Adams et al., Principles of Neurology, 6th ed, p270)
A syndrome characterized by marked limitation of abduction of the eye, variable limitation of adduction and retraction of the globe, and narrowing of the palpebral fissure on attempted adduction. The condition is caused by aberrant innervation of the lateral rectus by fibers of the OCULOMOTOR NERVE.
Traumatic injuries to the HYPOGLOSSAL NERVE.
Injuries to the optic nerve induced by a trauma to the face or head. These may occur with closed or penetrating injuries. Relatively minor compression of the superior aspect of orbit may also result in trauma to the optic nerve. Clinical manifestations may include visual loss, PAPILLEDEMA, and an afferent pupillary defect.
Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.
A retention cyst of the salivary gland, lacrimal sac, paranasal sinuses, appendix, or gallbladder. (Stedman, 26th ed)
Damage inflicted on the body as the direct or indirect result of an external force, with or without disruption of structural continuity.
Traumatic injuries to the facial nerve. This may result in FACIAL PARALYSIS, decreased lacrimation and salivation, and loss of taste sensation in the anterior tongue. The nerve may regenerate and reform its original pattern of innervation, or regenerate aberrantly, resulting in inappropriate lacrimation in response to gustatory stimuli (e.g., "crocodile tears") and other syndromes.
Voluntary or reflex-controlled movements of the eye.
Recording of nystagmus based on changes in the electrical field surrounding the eye produced by the difference in potential between the cornea and the retina.

It is formed by the posterior third of the superior surface of the body of the sphenoid (SPHENOID BONE), by the occipital, the petrous, and mastoid portions of the TEMPORAL BONE, and the posterior inferior angle of the PARIETAL BONE.
Treatment of muscles and nerves under pressure as a result of crush injuries.
Renewal or physiological repair of damaged nerve tissue.
Disease or damage involving the SCIATIC NERVE, which divides into the PERONEAL NERVE and TIBIAL NERVE (see also PERONEAL NEUROPATHIES and TIBIAL NEUROPATHY). Clinical manifestations may include SCIATICA or pain localized to the hip, PARESIS or PARALYSIS of posterior thigh muscles and muscles innervated by the peroneal and tibial nerves, and sensory loss involving the lateral and posterior thigh, posterior and lateral leg, and sole of the foot. The sciatic nerve may be affected by trauma; ISCHEMIA; COLLAGEN DISEASES; and other conditions. (From Adams et al., Principles of Neurology, 6th ed, p1363)
The inferior region of the skull consisting of an internal (cerebral), and an external (basilar) surface.
Intense or aching pain that occurs along the course or distribution of a peripheral or cranial nerve.

Traumatic injuries to the LINGUAL NERVE. It may be a complication following dental treatments.

Postlesional vestibular reorganization improves the gain but impairs the spatial tuning of the maculo-ocular reflex in frogs. (1/6)

The ramus anterior (RA) of N.VIII was sectioned unilaterally. Two months later we analyzed in vivo responses of the ipsi- and of the contralesional abducens nerve during horizontal and vertical linear acceleration in darkness. The contralesional abducens nerve had become responsive again to linear acceleration either because of a synaptic reorganization in the vestibular nuclei on the operated side and/or because of a reinnervation of the utricular macula by regenerating afferent nerve fibers. Significant differences in the onset latencies and in the acceleration sensitivities allowed a separation of RA frogs in a group without and in a group with functional utricular reinnervation. Most important, the vector orientation for maximal abducens nerve responses was clearly altered: postlesional synaptic reorganization resulted in the emergence of abducens nerve responses to vertical linear acceleration, a response component that was barely detectable in RA frogs with utricular reinnervation and that was absent in controls. The ipsilesional abducens nerve, however, exhibited unaltered responses in either group of RA frogs. The altered spatial tuning properties of contralesional abducens nerve responses are a direct consequence of the postlesional expansion of signals from intact afferent nerve and excitatory commissural fibers onto disfacilitated 2nd-order vestibular neurons on the operated side. These results corroborate the notion that postlesional vestibular reorganization activates a basic neural reaction pattern with more beneficial results at the cellular than at the network level. However, given that the underlying mechanism is activity-related, rehabilitative training after vestibular nerve lesion can be expected to shape the ongoing reorganization.  (+info)

Eye problem following foot surgery--abducens palsy as a complication of spinal anesthesia. (2/6)

BACKGROUND: Paralysis of abducens nerve is a very rare complication of lumbar puncture, which is a common procedure most often used for diagnostic and anesthetic purposes. CASE REPORT: A 38-year-old man underwent surgery for a left hallux valgus while he was under spinal anesthesia. On the first postoperative day, the patient experienced a severe headache that did not respond to standard nonsteroidal anti-inflammatory medication and hydration. During the second postoperative day, nausea and vomiting occurred. On the fourth postoperative day, nausea ceased completely but the patient complained of diplopia. Examination revealed bilateral strabismus with bilateral abducens nerve palsy. His diplopia resolved completely after 9 weeks and strabismus after 6 months. CONCLUSION: Abducens palsy following spinal anesthesia is a rare and reversible complication. Spinal anesthesia is still a feasible procedure for both the orthopaedic surgeon and the patient. Other types of anesthesia or performing spinal anesthesia with smaller diameter or atraumatic spinal needles may help decrease the incidence of abducens palsy. Informing the patient about the reversibility of the complication is essential during the follow-up because the palsy may last for as long as 6 months. Special attention must be paid to patient positioning following the operation. Recumbency and lying flat should be accomplished as soon as possible to prevent cerebrospinal fluid leakage and resultant intracranial hypotension. This becomes much more important if the patient has postdural puncture headache.  (+info)

Traumatic retroclival epidural hematoma in a child: case report. (3/6)

An 11-year-old girl presented with a very rare traumatic retroclival epidural hematoma manifesting as bilateral abducens nerve palsy, deviation of the uvula to the left, and weakened movement of tongue, which developed after a motor vehicle accident. The patient was treated conservatively and showed good outcome. Retroclival hematoma is a mainly pediatric entity usually associated with ligamentous injury at the craniocervical junction, and can be treated conservatively with good outcome.  (+info)

Sixth cranial nerve palsy following closed head injury in a child. (6/6)

A five year old female had an isolated abducens nerve palsy following closed head injury. There was no associated skull fracture, haematoma, or other cranial nerve injury. The significance, frequency, and differential diagnosis of traumatic sixth cranial nerve injury is discussed, particularly in paediatric patients. Management is symptomatic; occlusion with an eye pad may be used if diplopia is significant. In young children alternate day occlusion of each eye will help prevent amblyopia. Most cases improve within three months and many resolve by six months. Residual palsy at six months is likely to be permanent and surgical treatment may be needed.  (+info)

The sixth cranial nerve (CNVI) is also named the abducens nerve. It only controls eye movement from the lateral rectus muscle of the eye. The primary action is to help the eye move outward, towards the ear - this action is called ABDUCTION - hence, ABducens nerve. CNVI is unique in that it has a long path to its origin that takes sharp turns. The long pathway, location, and anatomical structures that this nerve courses over make it uniquely susceptible to damage from elevated intracranial pressure.

Purpose: Disrupting binocular vision during the first few months of life in a monkey results in strabismus. The objective of this study was to investigate response properties of abducens motoneurons (ABN) in relation to horizontal misalignment in monkeys with strabismus.. Methods: Burst-tonic (BT) activity of 49 neurons in the abducens nucleus (17-Left Abducens LTBT; 32-Right Abducens RTBT) was recorded from one strabismic monkey (OD: ~30° XT; OS: ~15° XT) during horizontal smooth pursuit (0.2 Hz, ±15°) under each monocular viewing condition. Neuronal firing rates (FR) and horizontal component of eye position and velocity (Epos, Evel) were used to identify regression coefficients (K-position, R-velocity, C-constant) in a first-order model (FR = K*Epos + R*Evel + C) for each tracking condition.. Results: Both RTBT and LTBT activity was well fit with the first order model equation. For RTBT motoneurons, the mean coefficients were K=5.4±3.8, R=1.4±0.6, C=41±62. Fit coefficients (K and R) ...
A triad of retro-ocular pain, discharging ear and abducens nerve palsy, as described by Gradenigo, has been recognized for 150 years. It has traditionally been treated with surgery, but recent advances in imaging, allied with improved antibiotic treatment, allow conservative management of these cases. We present two cases of Gradenigos syndrome: a 6-year-old child and a 70-year-old man, both without cholesteatoma, who were managed without mastoidectomy. They both had full recovery of abducens nerve function, although this took 6 and 12 weeks, respectively. In order to manage patients with Gradenigos syndrome safely, accurate diagnostic radiology is essential, and our findings are presented and discussed. With changing medical technology, a review of the diagnostic and treatment options for this rare but serious condition, is timely.
