Traumatic luxation of the stapes

Area of Science:

• Otolaryngology
• Traumatic Ear Injury
• Vestibular System

Background:

• Traumatic injuries to the ear can lead to significant functional deficits.
• Understanding the impact of foreign objects on the tympanic membrane and ossicular chain is crucial.

Observation:

• A case of middle and inner ear damage resulted from a knitting needle piercing the tympanic membrane.
• The incudo-stapedial joint was dislocated, and the stapes was displaced into the vestibule.

Findings:

• Surgical exploration and stapes extraction, followed by oval window reconstruction and prosthesis, partially improved the condition.
• Despite surgical intervention, inner ear function was not restored.

Implications:

• This case highlights the severe consequences of penetrating tympanic membrane injuries.
• It underscores the challenges in restoring inner ear function after traumatic stapes luxation.
• The study discusses surgical indications, timing, and techniques for managing traumatic stapes luxation.
