Purpose of Review
Malleostapedotomy (MS) is a challenging otologic surgical technique involving complex anatomic relationships and nuanced technical considerations. Over the past few decades, MS has been refined by development of customized prostheses and enhanced understanding of relevant ossicular anatomic dimensions. This article presents outcomes with a self-crimping angulated malleostapedotomy piston and reviews recent published advancements relevant to MS surgery.
Excellent results are reported with a self-crimping angulated nitinol piston including AB gap closure < 20 dB in the majority of cases and < 10 dB in many cases. Innovations in surgical technique include consideration for shifting the crimp site to the malleus neck, possible repositioning of the malleus, and use of an endoscope. Prosthesis sizing may be optimized by specialized instruments or preoperative 3D radiologic imaging.
Malleostapedotomy remains a viable option for management of stapes fixation when traditional incus-grip techniques are not possible. Ongoing innovation in technique and prosthesis may further advance hearing outcomes in to the future.

Comparison of hearing results of malleovestibulopexy and total ossicular replacement prosthesis for chronic otitis media patients with a mobile stapes footplate. Ann Otol Rhinol Laryngol. 2014;123:343–6. This randomized study found that malleostapedotomy (MS) and total ossicular replacement prosthesis result in comparable percentages of patients who obtain ABG closure < 10 dB and < 20 dB, although the mean post-operative gain was higher among patients who underwent MS.
