Summary
Blunt laryngeal trauma from strangulation can cause vocal cord paralysis. Fortunately, patients typically recover function within 4 to 20 days.
Area of Science:
- Otolaryngology
- Neurology
Background:
- Blunt trauma to the larynx is an increasingly recognized cause of vocal paralysis.
- Direct neurologic injury from strangulation requires careful consideration by laryngologists.
Observation:
- Four patients presenting with vocal paralysis following manual strangulation were evaluated.
- Three patients experienced unilateral vocal cord paralysis, while one had bilateral paralysis on two separate occasions.
Findings:
- All patients demonstrated recovery of vocal function within a 4 to 20-day period.
- The study correlates laryngeal strangulation injuries with other acute nerve compression syndromes.
Implications:
- This research highlights the importance of recognizing and evaluating strangulation assault injuries in clinical practice.
- Understanding the pathophysiology of nerve compression in these cases can improve patient outcomes.
