A targeted transcanalar epitympanotomy with annular bony ridge conservation was planned preoperatively, with 3D CT localization of the fixed part of the malleus head. The upper part of the malleus head and the superior ossified ligament of the malleus were drilled. A 0.6 mm stapedotomy was performed and a piston inserted. The patient's recovery was uneventful, with closure of the air-bone gap on her postoperative audiogram, associated with an overclosure in 500Hz, 1kHz, 2 kHz and 4 kHz.
