Clinical Results with an Active Middle Ear Implant in the Oval Window
... often requires drilling the bony overhang with the risk of cochlear trauma [7]. This is due to restrictions in the approach, anatomical variations, and the relatively large diameter of the FMT (1.6 mm) as compared to the opening of the round window niche (1.3–1.6 mm) [8, 9]. Furthermore, permanently ...
