Summary
Head injuries can cause vertigo and hearing loss. While vestibular symptoms often resolve, sensorineural hearing loss from temporal bone fractures may persist, impacting 75% of patients.
Area of Science:
- Otolaryngology
- Neurology
- Traumatology
Background:
- Vertigo is a frequent, yet often underestimated, symptom following head trauma.
- Mechanisms of vestibular system injury are less understood than auditory system damage.
- Temporal bone fractures are a significant cause of post-traumatic vestibular and auditory dysfunction.
Purpose of the Study:
- To investigate the prevalence and characteristics of vestibular and auditory sequelae in patients with temporal bone fractures.
- To analyze the correlation between radiological findings and clinical outcomes.
- To evaluate the long-term impact of these injuries on hearing and balance.
Main Methods:
- Review and re-examination of 20 patients with temporal bone fractures.
- Analysis of conventional X-ray, computerized tomography (CT), clinical, otoneurological, and audiological findings.
- Follow-up assessments including computerized electro-oculography.
Main Results:
- Radiological evidence of fractures in approximately 65% of patients.
- Half of the patients reported dizziness; positional nystagmus was the most common vestibular finding.
- 75% experienced permanent hearing impairment: 20% due to ossicular chain fractures (conductive), 55% sensorineural hearing loss. Dizziness resolved in all patients, but sensorineural hearing loss often persisted.
Conclusions:
- Temporal bone fractures frequently lead to persistent dizziness and significant hearing loss.
- While vestibular symptoms generally improve, sensorineural hearing loss is a common long-term complication.
- Surgical intervention may be indicated for persistent conductive hearing loss, but sensorineural deficits often remain.
