Implant-retained auricular prostheses: a clinical challenge.

Area of Science:

• Otolaryngology
• Oral and Maxillofacial Surgery
• Biomaterials Science

Background:

• Congenital or acquired loss of the pinna (auricle) presents significant reconstructive challenges in adults.
• Traditional surgical reconstruction often yields suboptimal aesthetic and functional outcomes.

Purpose of the Study:

• To evaluate the efficacy and patient satisfaction of implant-retained auricular prostheses for ear reconstruction.
• To assess the outcomes of both magnet-retained and bar-and-clip retained prostheses.

Main Methods:

• Retrospective study of eight patients with partial or complete ear loss.
• Placement of three titanium implants per missing pinna for osseointegration.
• Rehabilitation with either magnet-retained or bar-and-clip retained auricular prostheses.

Main Results:

• A total of 27 implants were placed with an average follow-up of 21 months.
• Two sites exhibited peri-implant tissue reactions; overall outcomes indicated good retention and patient satisfaction.
• Both retention methods demonstrated positive results, suggesting suitability for various cases.

Conclusions:

• Implant-retained auricular prostheses provide a successful alternative for ear reconstruction.
• This method achieves good retention and high patient satisfaction, addressing limitations of surgical reconstruction.
• Further long-term studies are needed to monitor for delayed complications.
