Biointegrated ventilation tube: current status and new developments.

The biointegrated (HydroxylVent) ventilation tube has been used over the past 3 years in a variety of clinical cases. The chief indication for its use is unresolving eustachian tube dysfunction and failure of more conventional medical and surgical therapy. The surgical technique and a postoperative management are described. New directions in clinical research include a larger lumen prosthesis and a compound prosthesis of hydroxylapatite with Teflon lining.
