Summary
Head injury can cause supraorbital nerve damage, leading to neurological symptoms. This study identifies traumatic supraorbital neuralgia, distinct from the common idiopathic form, in four patients with normal neuroimaging.
Area of Science:
- Neurology
- Neuroscience
- Traumatology
Background:
- Head injuries are common causes of neurological sequelae.
- Supraorbital nerve injury can result from trauma, but is often underdiagnosed.
- Idiopathic supraorbital neuralgia is a recognized condition, but traumatic etiology requires specific consideration.
Observation:
- Four patients presented with neurological symptoms post-head injury.
- Standard neuroimaging revealed no abnormalities in these patients.
- Clinical examination identified altered sensation in the supraorbital nerve distribution.
Findings:
- The observed symptoms are consistent with traumatic supraorbital neuralgia.
- This condition presents differently from idiopathic supraorbital neuralgia.
- Normal neuroimaging highlights the importance of detailed clinical assessment.
Implications:
- Recognizing traumatic supraorbital neuralgia is crucial for accurate diagnosis and management.
- This condition may be more prevalent than previously thought.
- Further research is needed to delineate the pathophysiology and treatment of traumatic supraorbital neuralgia.

01:14Cranial Nerves: Types Part I
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.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

01:19Cranial Nerves: Overview and Anatomy
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...
01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:22Cranial Nerves: Types Part II
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.
