Summary
Mandibular trauma can cause temporal bone fractures and facial paralysis. Conservative treatment led to significant recovery of facial muscle function in a bicycle accident victim.
Area of Science:
- Neurology
- Traumatology
- Otolaryngology
Background:
- Posteriorly directed forces to the mandible can cause condylar displacement.
- This displacement may lead to temporal bone fractures and cranial base involvement.
Observation:
- A 30-year-old male sustained facial paralysis post-bicycle accident.
- Clinical signs included postauricular ecchymosis and facial muscle weakness, without obvious facial fractures.
Findings:
- CT scan revealed a left temporal bone fracture with complete facial nerve paralysis.
- Conservative management was initiated by the neurosurgical team.
Implications:
- This case highlights a rare consequence of mandibular trauma.
- Conservative treatment can yield favorable outcomes for facial nerve recovery after temporal bone fractures.

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...

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.

01:22Botulism
Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
