Summary
Hydroxylapatite hybrid prostheses improve ossicular reconstruction in chronic ear surgery. This study reviews 60 cases using Black HaH prostheses, showing successful air-bone gap closure and low complication rates.
Area of Science:
- Otolaryngology
- Biomaterials Science
- Surgical Innovation
Background:
- Chronic ear surgery often requires ossicular reconstruction due to hearing loss.
- Traditional prostheses have limitations, driving the need for improved biocompatibility and design.
Purpose of the Study:
- To review the senior author's experience with Black hydroxylapatite hybrid (HaH) prostheses in ossicular reconstruction.
- To evaluate the efficacy and safety of HaH prostheses in chronic ear surgery.
Main Methods:
- Review of 60 cases using Black HaH prostheses (19 TORPs, 41 PORPs) with at least 1-year follow-up.
- Analysis of audiometric data for air-bone gap closure.
- Assessment of complication and extrusion rates.
Main Results:
- Successful air-bone gap closure achieved in the reviewed cases.
- Low rates of complications and prosthesis extrusion observed.
- Performance compared favorably to other ossicular replacement prostheses.
Conclusions:
- Hydroxylapatite hybrid prostheses are effective for ossicular reconstruction in chronic ear surgery.
- The Black HaH prosthesis demonstrates a favorable safety and efficacy profile.
- This study provides follow-up data supporting the use of HaH prostheses.
