The advent of piezoelectric powered instrumentation in recent ears is seen as a useful adjunct for endoscopic ear surgery (EES) with more centers starting to employ the system in clinical practice. Asians typically have a narrower External Ear Canal (EAC) compared to Caucasians and it is not easy to get a good view of the tympanic membrane essential for a good surgical result and post operative recovery.

In this video, we will demonstrate the set up, settings and use of the Mectron system in a typical EES operating session for tympanoplasty with canalpasty.

The Mectron system is useful for bony removal whilst preserving soft tissue structures eg nerves and skin flaps. One disadvantage is learning to operate underwater as the device requires a fluid medium to work in. There is a learning curve to using the Mectron but once that is acheived, the EES surgeon has a very safe and useful tool. The other important point is to minimise bleeding in the surgical field as the blood obscures the endoscopic view.

The Mectron piezoelectric system is a safe and useful adjunct to EES, especially for bone removal over nerves and other soft tissue structures.
