Background summary
Maxillomandibular advancement (MMA) is a successful surgical treatment for
patients with moderate to severe obstructive sleep apnea (OSA). It is a form of
orthognathic surgery and it includes forward repositioning of the maxilla and
mandible to put more tension on the soft tissue and widening the upper airway.
This results in improvement of polysomnography outcomes, sleep and quality of
life. After the surgery change in velopharyngeal symptoms, such as nasality,
swallowing and speech, could exist. Some patients found improvement
velopharyngeal insufficiency (VPI), however other patients develop VPI. (Li).
There are some studies that describe VPI after orthognathic surgery in cleft
palate patients. However little is known about VPI after MMA in patients with
OSA. Using objective and subjective measurement methods, we can examine the
course of VPI after an MMA. With this understanding, we can better prepare
patients for the postoperative symptoms of an MMA. In addition, patients could
be better managed with speech therapy postoperatively.
Study objective
To examine the course of velopharyngeal insufficiency after maxillomandibular
advancement in patients with obstructive sleep apnea.

Study burden and risks
All test are non invasive. There will be no physical and physiological
discomfort. The extra burden and risk associated with this study are
negligible.
