Trigeminal neurotrophic damage
Introduction
Introduction to trigeminal neurotrophic damage Trigeminal trophicles (trigeminal trophicles), also known as trigeminal neurotrophic syndrome, produces lesions such as nutrient ulcers caused by a lack of skin or mucosal sensation dominated by the trigeminal nerve. basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: keratitis, corneal ulcer, conjunctivitis, iritis
Cause
Causes of trigeminal neurotrophic damage
(1) Causes of the disease
Tumors, infections, trauma, surgery and vascular injuries in this area can induce this disease, such as:
1. After the half-moon ganglion alcohol injection, the side part feels lost due to damage to the sensory nerve fibers.
2. Medullary cavity can cause facial skin nutritional ulcers.
3. Leprosy trigeminal neuritis can produce nasal ulcers.
4. The occlusion of the inferior cerebellar artery interferes with the sensory function of the brain stem, causing acute sensory loss or ulceration of the face.
5. Trauma and fractures can also produce neurotrophic ulcers.
(two) pathogenesis
A lesion such as a nutritional ulcer is produced by the lack of skin or mucous membrane sensation dominated by the trigeminal nerve.
Prevention
Trigeminal neurotrophic damage prevention
Remove the cause, prevent trauma, and treat the cause.
Complication
Trigeminal neurotrophic damage complications Complications keratitis corneal ulcer conjunctivitis iritis
Keratitis, corneal ulcers, conjunctivitis, iritis, facial cramps or paralysis, paresthesia and dryness of the nasal mucosa.
Symptom
Symptoms of trigeminal neurotrophic damage Common symptoms Corneal ulcer keratitis Painful face convulsions scars Facial muscles Ramie Muddy dry
More common in a few weeks to a few months after trigeminal nerve surgery, manifested as scarring of the nasal wing, and then form a crescent-shaped painless ulcer, gradually expanding to the nasolabial fold, cheeks and upper lip, ulcer bleeding, long-term unhealed, It can destroy the nasal cartilage. When the scar formed by the ulcer collapses, it can cause the upper lip to be upturned. When the nasal vestibule is involved, there may be scarring. The tip of the nose is generally not involved. Occasionally, the forehead, scalp and humerus may also have nutritional ulcers. The lesions are mostly unilateral. The above symptoms may be associated with neurological disorders such as keratitis, corneal ulcer, conjunctivitis, iritis, facial paralysis or paralysis, paresthesia and dryness of the nasal mucosa.
Examine
Trigeminal neurotrophic damage examination
Trigeminal neurotrophic damage examination items: trigeminal nerve examination, motor function examination of trigeminal nerve, facial sensation examination of trigeminal nerve, blood routine, blood examination.
Diagnosis
Diagnosis and diagnosis of trigeminal neurotrophic damage
More common in a few weeks to a few months after trigeminal nerve surgery, manifested as scarring of the nasal wing, and then form a crescent-shaped painless ulcer, gradually expanding to the nasolabial fold, cheeks and upper lip, ulcer bleeding, long-term unhealed, It can destroy the nasal cartilage and make a diagnosis based on the characteristics of the disease.
