It is with great pleasure we introduce our first guest blogger of the Baha Blog, Professor Robert Stokroos from Maastricht University Medical Center, the Netherlands. For over 20 years he has been leading research efforts in the field of bone conduction. He is currently leading a pan European evaluation of the improvements provided by the DermaLock technology. In this post Prof. Stokroos presents his team’s experience:

“Percutaneous bone anchored hearing devices have changed hearing possibilities for many patients over the years. Since 1992 as a junior doctor, I was involved in this treatment when Baha surgery was still considered very special.

Since then, things have changed a lot. The Baha has become part of our daily clinical practice. As our clinical experience in Maastricht grew, the downside of having a percutaneous implant became apparent.

From our earlier studies we conclude that, as far as Baha surgey is concerned, less is more.

In other words, when working with the old generation of implants the less skin we reduced, the less scar tissue and the better the patient outcome. This was contradictory to what we previously had learned from our seniors, who taught us the importance of skin reduction and having immobile skin around the abutment. In fact, if there was a problem, we blamed ourselves for not thinning the skin sufficiently.

With the introduction of the new DermaLock technology, we feel skin reduction is now unnecessary. The abutment coating prevents the skin from growing down around the implant, thereby naturally keeping it in place.

The clinical impression has been extremely promising. The new technique in combination with the DermaLock has quickly gained wide global acceptance.

Our job as academics is to confirm all these great developments. A pan European effort has been assembled with centers from France, Spain, Sweden and the Netherlands to compare outcomes when using the traditional surgical technique to the latest surgical technique with the DermaLock Abutment.

Our clinical impression is that this is a major step in improving patient outcomes. Soon we will start analysing results. I’ll keep you posted!”

  1. Hi Professor,

    I had my Baha surgery in 2011 in Australia and have the older abutment (and a Baha 3). I needed 2 skin revisions in the first few months post-op. I have since had a couple of minor flare ups but take good care of the site.

    Would patients like me benefit from changing to the new Derma Lock abutment?
