Although ossiculoplasty, also known as ossicular chain reconstruction (OCR), was attempted initially in the early 1900s, it was not until the 1950s that it became commonplace and relatively well understood. Since then, there have been numerous technologic advances and a gain in the understanding of ossiculoplasty. However, successful OCR with resulting long-term stability can be a daunting task. Typically, the most common condition requiring revision OCR is chronic suppurative otitis media (COM) with or without cholesteatoma. Primary and revision OCR are performed also for blunt and penetrating trauma-induced conductive hearing loss, congenital defects (eg, atresia), and benign and malignant tumors. Typically, reconstruction in ears with COM is more difficult than in ears without infection. This article discusses the key factors involved in successful revision OCR.
