Hyoid bone elevation: a sign of tracheal transection

Area of Science:

• Radiology
• Trauma Surgery
• Anatomy

Background:

• Traumatic neck injuries pose diagnostic challenges.
• Accurate assessment is crucial for timely intervention.
• Radiographic evaluation plays a key role in identifying severe injuries.

Purpose of the Study:

• To highlight the significance of hyoid bone position in lateral neck radiographs.
• To correlate specific hyoid bone findings with tracheal transection.
• To emphasize the importance of prompt surgical exploration in suspected cases.

Main Methods:

• Retrospective review of five severe neck injury cases.
• Analysis of lateral cervical radiographs focusing on hyoid bone location.
• Correlation of radiographic findings with surgical outcomes.

Main Results:

• Specific hyoid bone positions (above C3 body or <2cm from mandibular angle) were associated with tracheal injury.
• Presence of cervical soft-tissue air was a concurrent indicator.
• These findings predicted the likelihood of tracheal transection.

Conclusions:

• Hyoid bone positioning on lateral radiographs is a valuable indicator in traumatic neck injuries.
• Combined hyoid bone findings and cervical soft-tissue air strongly suggest tracheal transection.
• Immediate surgical exploration is warranted based on these radiographic signs.
