Malleostapedotomy Prosthesis Size and Shape: Key Measurements From a Temporal Bone Study
Otology & Neurotology, 06/29/2012
Gluth MB et al. – A total crimped prosthesis length of at least 7.75 mm is required to accommodate the range of interossicular measurements, yet production of longer prostheses is wise owing to the limited number of temporal bones studied. Furthermore, the use of a single–length prosthesis for all malleostapedotomy (MS) cases will not suffice except when cutting a sufficiently long prosthesis to its desired length. Understanding of the ossicular anatomy can be used to bend the MS piston to favorably affect the orientation of the prosthesis barrel into the vestibule.
