Another study has found that bimaxillary advancement surgery, also know as maxillomandibular advancement surgery (MMA), is a highly effective treatment for those suffering from obstructive sleep apnea (OSA). The sleep apnea study, which was conducted by the David Geffen School of Medicine at UCLA, also determined that the upper and lower jaw surgery is even more effective on those with moderate to severe sleep apnea.
Overall, the study found that bimaxillary advancement surgery is 98.8 percent effective.
Sleep Apnea Surgery Study Methods and Details
For the study, which was published in the November 25, 2015 issue of Otolaryngol Head Neck Surgery, researchers looked at 45 different studies regarding bimaxillary advancement surgery and a total of 518 different patients that underwent the procedure. Those included in the study met the following criteria:
All patients were adults who underwent bimaxillary advancement surgery as treatment for OSA.
None of the patients also had adjunctive surgeries (including tonsillectomy, uvulopalatopharyngoplasty, and partial glossectomy).
The outcome recorded preoperative and postoperative quantitative outcomes for both the apnea-hypopnea index (AHI) and/or respiratory disturbance index (RDI).
The study included data regarding individual patients.
To find the studies used, researchers looked at databases in all languages using a variety of keyword searches. Databases included The Cochrane Library, Scopus, Web of Science, and MEDLINE.
Bimaxillary Advancement Surgery Study Results
Of the 518 patients studied, 512 showed significant improvement in their apnea-hypopnea index (AHI) and/or respiratory disturbance index (RDI). Significant improvements were also seen in the mean (SD) postoperative oxygen saturation nadir and in the Epworth Sleepiness Scale score. In other words, 98.8 percent of patients improved their sleep apnea symptoms and many also improved their oxygen intake and sleepiness levels. The average apnea-hypopnea index score decreased by 80 percent after surgery and the average respiratory disturbance index score decreased by 65 percent.
In addition to determining the overall success of maxillomandibular advancement surgery (MMA), the study also determined that the surgery had the biggest benefit for those with severe sleep apnea, while those with more mild sleep apnea symptoms saw more subtle changes.
The scientists concluded that this study will help optimize patient selection for MMA surgery, while further study will likely provide additional insight.
