Novel Ossicular Chain Reconstruction Techniques (2023 AMW)
2023 AAO-HNSF Annual Meeting & OTO Experience
Many techniques have been described for ossicular chain reconstruction (OCR). Despite historic innovations, long-term hearing results with OCR are often less than optimal due to prosthesis issues such as: angulation, dislocation, migration, erosion, and extrusion. Some issues are related to the inimical habitat of the chronic ear. Others are secondary to an incomplete understanding of fundamental middle ear mechanics and the many technical challenges associated with OCR. The result is wide variability in success rates. This course will review: (1) challenges encountered in chronic ears during OCR, (2) fundamental concepts of middle ear mechanics that are crucial for long-term OCR success, and (3) many OCR techniques that are available including: the use of homograft ossicles, cortical bone & cartilage grafts, partial and total ossicular prostheses, the use of glass ionomer cement, and endoskeletal OCR with the Kraus K-Helix prostheses.
