Summary
Ocular movement nerve palsy after mild head trauma is rare. Management involves observation for uncomplicated cases, focusing on underlying lesions if found, as mild trauma can cause severe injury.
Area of Science:
- Neurosurgery
- Ophthalmology
- Neurology
Background:
- Ocular movement nerve palsy (OMNP) following mild head trauma is uncommon.
- Inconsistent definitions complicate OMNP management and prognosis assessment.
Purpose of the Study:
- To investigate the characteristics, management, and prognosis of OMNP after mild head trauma.
- To clarify the clinical presentation and outcomes of this rare condition.
Main Methods:
- Retrospective review of medical records from a single institution.
- Systematic review of published literature on OMNP post-mild head trauma.
Main Results:
- Thirty-one patients were identified, with cranial nerves III, IV, and VI affected in 54.8%, 3.2%, and 45.2% respectively.
- Complete resolution occurred in all cases within the institution's series, but only 54.6% overall within 10 days to 13 months.
- Intracranial findings beyond TBI were present in 25.8% of patients.
Conclusions:
- OMNP after mild head trauma is a rare neurosurgical entity.
- Observation is key for patients without intracranial findings; treatment should target identified lesions.
- Mild trauma does not guarantee mild injury or a favorable outcome in OMNP.

6.3K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.

01:17Accessory Structures of the Eye
4.3K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

01:19Muscles that Move the Head
6.7K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

01:28Angle Closure Glaucoma: Treatment
1.5K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

7.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
