Ossicular injury caused by a knitting needle

Area of Science:

• Otolaryngology
• Trauma Surgery

Background:

• Ossicular chain disruption is a rare complication of temporal bone trauma, but can also result from direct penetrating injuries.
• Such injuries often lead to conductive hearing loss and vertigo, with potential for facial nerve damage.

Purpose of the Study:

• To describe a case of ossicular chain disruption due to penetrating ear trauma.
• To highlight the diagnostic and management considerations for this specific type of injury.

Main Methods:

• Case report of a young male with penetrating left ear trauma from a knitting needle.
• Clinical presentation of severe vertigo and conductive hearing loss.
• Diagnostic imaging using computed tomography (CT) was considered the investigation of choice.

Main Results:

• The penetrating trauma resulted in ossicular chain disruption.
• The patient experienced severe vertigo and conductive hearing loss.
• Conservative management with bed rest and medication controlled vertigo, leading to recovery.

Conclusions:

• Penetrating middle ear trauma requires distinct management compared to blunt trauma.
• CT imaging is crucial for accurate diagnosis and characterization of penetrating ossicular injuries.
• Surgical repair, whether immediate or delayed, can yield satisfying hearing results, though late interventions may face challenges like adhesions.
