BACKGROUND: Congenital ossicular anomalies are presented as non-progressive conductive hearing loss without history of head trauma or chronic infection. Early diagnosis is very important because most cases can be corrected by appropriate surgical treatment. The main purpose of this study was to analyze the types of congenital ossicular anomalies and compare the postoperative hearing outcomes based on their classification. METHODS: From July 2007 to March 2014 in National Taiwan University Hospital, exploratory tympanotomies were performed on 20 ears of 18 patients with nonprogressive conductive hearing loss but without external ear malformations. The preoperative and postoperative audiological findings, operative findings, types of ossicular chain reconstruction were reviewed. Mean air conduction (MAC) and bone conduction (MBC) thresholds were recorded at 0.5, 1, 2 and 4 k Hz. Th...
