Study to Determine the Effectiveness of Pillar Palatal Implants to Treat Obstructive Sleep Apnea

December 10, 2007 updated by: University of Cincinnati

Pillar Palatal Implant System Multi-Institutional, Randomized Placebo-Controlled Study for Obstructive Sleep Apnea

The Pillar palatal implant procedure is a minimally invasive and commercially available treatment for mild to moderate obstructive sleep apnea (OSA) in the United States and Europe. The implants are placed into the soft area in the roof of the mouth providing support to the soft palate. This research is being done to compare daytime sleepiness and sleep related quality of life after palatal implants.

Detailed Description

Patients will be enrolled into the study based on sleep study results, a physical exam and inclusion/exclusion criteria. Once enrolled, patients are randomized into either the Pillar palatal implant group or a placebo/sham group.

In both cases, patients come into the office for placement of the implants. This is an outpatient procedure. Patients are followed at one week, one month and 3 months. At each follow-up visit, patients will undergo a physical exam and complete questionnaires related to sleep and quality of life. Patients will also undergo reaction time testing on hand-held device similar to a pocket video game. At the three month visit, patients will return to the sleep lab for another sleep study.
