Introduction:

During the course of studies and also in standard medical care (German NUB-process) patients with obstructive sleep apnea have been supplied with hypoglossal nerve stimulation devices over the last seven years. When assessing the procedures security, the feasibility of explantation and re-implantation should be considered.

Methods:

Five Patients with an implanted hypoglossal nerve stimulation device with respiratory sensing. We report about technical surgical aspects of implanting and re-implanting with another stimulation-system.

Results:

At our clinic nine patients have been implanted with a hypoglossal nerve stimulation system with respiratory sensing in the year 2012. Until 2017 the system was explanted at five patients for different reasons. Two of these patients were re-implanted with another system with respiratory sensing in the same session. Due to remarkable scar formation around all the implanted material, the procedures have been technical challenging. All of them had to be performed with the help of a surgical microscope. None of the patients suffered from severe surgical complications. At two patients we noticed a temporary incomplete paresis of the hypoglossal nerve after surgery.

Conclusions:

Explantations and Re-Implantations are technically challenging, but possible.
