TORPs and PORPs: causes of failure

Area of Science:

• Otolaryngology
• Surgical Innovation
• Auditory Reconstruction

Background:

• Tympanoplasty with ossicular replacement prostheses is a common procedure for hearing restoration.
• Failures can lead to revision surgeries and suboptimal hearing outcomes.
• Intact canal wall tympanoplasty presents specific challenges for prosthesis stability.

Purpose of the Study:

• To identify the primary causes of failure for total and partial ossicular replacement prostheses.
• To evaluate the impact of specific surgical devices on preventing prosthesis failure.
• To outline management strategies for graft perforation and hearing impairment post-tympanoplasty.

Main Methods:

• Review of literature on ossicular replacement prosthesis failures in staged intact canal wall tympanoplasty.
• Analysis of surgical techniques and devices implicated in prosthesis success or failure.
• Case review of patients experiencing graft perforation or hearing impairment.

Main Results:

• Key failure modes include prosthesis extrusion, malpositioning, and biocompatibility issues.
• Utilization of specialized surgical devices significantly reduces the incidence of prosthesis failure.
• Graft perforations and persistent hearing impairment are common complications necessitating revision.

Conclusions:

• Preventable factors contribute significantly to ossicular replacement prosthesis failure.
• Adoption of specific surgical devices can enhance prosthesis longevity and surgical success.
• Early identification and management of complications are crucial for optimal patient outcomes.
