This is a rare case of congenital stapedial suprastructure fixation with normal footplate mobility. In this patient, development of the second branchial arch was arrested. When performing exploratory tympanotomy for stapedial fixation, one must keep in mind that normal footplate mobility is possible.
Although several cases of familial ossicular anomaly have been reported, this is the first report of an incus anomaly and stapes fixation combined with a facial nerve anomaly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
