Preliminary Evaluation of a RCMP to Predict Failure of Maxillomandibular Advancement Surgery for OSA

Study overview

Maxillomandibular advancement (MMA) surgery, one of the most successful surgical procedures for the treatment of obstructive sleep apnea (OSA), is predominantly used to manage patients with moderate to severe OSA. However, limiting factors include incomplete response in some cases, unfavorable facial changes as a result of large advancements, and risk of malocclusion or malunion. This study will be done to determine predictors of success with MMA surgery in patients with moderate to severe OSA. Studies have already shown the value of a remote controlled mandibular positioner (RCMP) device to identify the correct level of therapeutic protrusion needed with oral appliance therapy. Moreover, some patients experience a dose dependent improvement in sleep parameters based on the degree of protrusion during the titration study. Use of RCMP as a means to identify potential candidates for MMA, may help customize treatment options for patients with OSA by providing predictive value.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
