The Gyrus ACMI Micron Adjustable Titanium TORP 70141044 (Centered) is a middle ear prosthesis engineered for ossicular chain reconstruction (specifically, as a Total Ossicular Replacement Prosthesis). Its defining feature is the adjustable length from 2.00 mm up to 10.00 mm, which allows the surgeon to intraoperatively tailor the prosthesis length to match varying distances between the tympanic membrane / manubrium and the footplate (or prosthetic footplate substitute). This adjustability reduces the need to carry multiple fixed-length prostheses and provides flexibility in achieving optimal contact and tension in the reconstructed ossicular chain.

Constructed from titanium, the prosthesis benefits from a favorable strength-to-weight ratio, biocompatibility, and resistance to corrosion or long-term degradation. The “Micron®” finishing process applied to the titanium surface reportedly smooths and “dulls” the implant surface, which can reduce glare under surgical optics and potentially reduce the risk of irritation or micro-motion at tissue interfaces. The centered TORP design means that the head of the prosthesis aligns centrally over the stapes footplate (or its substitute) rather than being offset, which can facilitate symmetric force transmission and reduce eccentric loading.

The open-head architecture gives the surgeon enhanced visualization during positioning, ensuring correct orientation and alignment with the footplate and tympanic membrane. Because the device is sterile and intended for single use, it removes concerns of implant degradation over sterilization cycles. In clinical use, the adjustable TORP is particularly valuable in revision middle ear surgeries or anatomies with variable distances, where precision fitting is critical for restoring sound conduction while minimizing stress on the prosthesis or neighboring structures.
