Abstract
Background and Objectives：There are many different types of congenital ossicular anomalies, which may be broadly divided into major ear anomalies and minor ear anomalies. Minor congenital anomalies are restricted to the midle ear, while major anomalies of the middle ear described in the literature makes it difficult to compare and analyze it. The objective of this study is to review and analyze the isolated congenital ossicular anomalies published in the Korean literatures with special reference to the pattern of anomalies and surgical treatment results, and to propose a new systematic clasification of isolated congenital ossicular anomalies. Subjects and Method：We reviewed retrospectively 10 Korean literatures concerning isolated congenital University Hospital from Jan 2002 to June 2003, which were not reported in the literature. Among the total 126 cases of isolated congenital ossicular anomalies, folow-up on the hearing results was possible in 112 ears. Results：We proposed a new classifi-cation of isolated congenital ossicular anomalies using 5 types based on the stapes status. Twenty-six anomalous patterns were detected out of 126 cases of isolated congenital ossicular anomalies. Using the new clasification, the more severe anomaly Conclusion：Ossicular anomalies were detected without a certain rule of pattern, and big variety of those patterns could be detected in the future. Our proposed new classification will be helpful to analyze the pattern and surgical result of congenital ossicular anomalies.
