Difficulty in high-pitched phonation by laryngeal trauma.

Area of Science:

• Otolaryngology
• Voice Science
• Trauma Surgery

Background:

• Laryngeal trauma can lead to significant voice dysfunction.
• High-pitched phonation difficulties are a key indicator of specific laryngeal injuries.
• Accurate diagnosis is crucial for effective voice disorder management.

Observation:

• A patient presented with primary difficulty in high-pitched phonation following laryngeal trauma.
• Diagnostic workup included physical examination, phonatory function tests, CT scan, and electromyography.
• The voice disorder was attributed to a fractured thyroid cartilage impinging on the cricoid cartilage.

Findings:

• Phonatory function tests are vital for diagnosing the mechanism of voice disorders.
• Computed tomographic scan and electromyography confirmed thyroid cartilage fracture and fixation.
• Surgical intervention via open reduction successfully resolved the phonatory impairment.

Implications:

• This case highlights the importance of specialized phonatory function tests in laryngeal trauma.
• Prompt surgical intervention can restore voice function after specific laryngeal fractures.
• Understanding the biomechanics of laryngeal injury aids in treatment planning and patient recovery.
