Summary
Autografting the patient's own incus offers excellent long-term tolerance and cost-effectiveness for columellar reconstruction in stapes superstructure absence. This ossicular reconstruction method significantly improves hearing outcomes.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Biomaterials in Reconstruction
Context:
- Cholesteatoma surgery often results in stapes superstructure lysis, necessitating columellar reconstruction.
- Biocompatible prostheses are common but raise questions about cost and long-term tolerance.
- Autograft ossicular reconstruction presents an alternative for these challenging cases.
Purpose:
- To evaluate the efficacy and tolerance of autograft ossicular reconstruction using the patient's incus for columellar repair.
- To compare outcomes with traditional prosthetic approaches.
- To assess the feasibility of using the incus in Type III ossiculoplasty.
Summary:
- A retrospective study of 82 patients with cholesteatoma and stapes lysis explored columellar repair options.
- Autografting the incus (54 cases) was compared to prostheses and cortical bone grafts.
- The Autogreffe Tympanum-Cartilage-Os-Platinum (ATCOP) technique facilitates incus interposition for Type III ossiculoplasty.
Impact:
- Autografting the incus resulted in a significant average air-bone gap improvement of 19 decibels (final average 23 dB).
- This method offers excellent tolerance and zero cost compared to prostheses.
- Patient's incus is a preferred material for columellar repair, reserving prostheses for cases of absent or destroyed incus.
