Secondary Spinal Cord Injury llI: Pathophysiology

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Summary

This summary is machine-generated.

A head injury can cause contralateral deafness, affecting the ear opposite the injury site. This rare case highlights hearing loss without temporal bone fractures after blunt force trauma.

Area of Science:

Neurology
Otolaryngology
Trauma Medicine

Background:

Head injuries are a common cause of auditory complications.
Contralateral deafness following head trauma is exceptionally rare.

Observation:

A 31-year-old male experienced profound right-sided sensorineural deafness after a left-sided blunt head injury.
Symptoms included dysequilibrium and vertigo, with hearing loss persisting despite dysequilibrium improvement.

Findings:

High-definition computed tomography revealed no fractures or fistulas.
Audiometry confirmed total sensorineural deafness in the affected ear.

Implications:

This case suggests non-fracture related mechanisms for contralateral deafness post-head injury.
Further research into the pathophysiology of such injuries is warranted.
Highlights the importance of considering unusual presentations in audiological assessments after trauma.
