|January 1, 1983
Summary
A new surgical technique using titanium implants offers a stable and aesthetically pleasing solution for attaching prosthetic ears (epistheses). This method ensures secure bone anchorage and skin integration, improving outcomes for patients with missing outer ears.
Area of Science:
- Otolaryngology
- Biomedical Engineering
- Plastic Surgery
Background:
- Traditional methods for attaching ear prostheses (epistheses) to eyeglasses result in insecure fixation and suboptimal cosmetic outcomes.
- Patients with missing outer ears often face challenges with existing prosthetic attachment methods.
Observation:
- A novel technique involves surgically inserting threaded titanium implants into the temporal bone.
- After a healing period of 3-4 months, abutments are attached to the implants, penetrating the skin.
- A silicone ear prosthesis is then affixed to these abutments.
Findings:
- Seven patients with congenital, hereditary, trauma-related, or tumor-related outer ear absence have undergone this procedure.
- Follow-up periods extend up to 3.5 years.
- No complications regarding bone anchorage or skin penetration have been reported.
Implications:
- This innovative approach provides a stable and cosmetically superior method for ear prosthesis attachment.
- The technique demonstrates promising long-term results and patient satisfaction in reconstructive surgery.
- Further research could validate this method for a wider patient population requiring auricular reconstruction.
