PROGRAM DESCRIPTION: 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: (1) angulation, (2) dislocation, (3) migration, (4) erosion, and (5)cextrusion. 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 a 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 (eOCR) with the Kraus K-Helix Crown and Piston prostheses.

Learning Objectives:

  1. Demonstrate existing techniques to reconstruct the ossicular chain and discuss the pitfalls of conventional OCR.
  2. Explain newest techniques for ossicular chain reconstruction utilizing glass ionomer bone cement and methodology to maintain the given anatomy, improve air-bone gap closure rates, and achieve long-term, stable hearing outcomes.
  3. Learn time tested methods to improve long-term hearing outcomes for patients with ossicular discontinuity.
