Abstract:Maxillomandibular advancement (MMA) is a surgical option for obstructive sleep apnea (OSA). MMA involves forward-fixing the maxilla and mandible approximately 10 mm via Le Fort I maxillary and sagittal split mandibular osteotomies. We retrospectively reviewed outcomes from 24 consecutive OSA patients who underwent MMA at our institution. MMA resulted in an 83% reduction in the group mean apnea-hypopnea index (AHI) per polysomnography an average of 6.7 months after surgery. Forty-two percent of patient… Show more

“…Vigneron et al [ 11 ] performed maxillomandibular advancement surgery (MMA) on OSA patients and obtained a 50–80% reduction in AHI values after the surgery. Another study by Varghese et al [ 12 ] showed an 83% reduction in AHI value 6.7 months after the surgery. These results suggest that MMA can significantly reduce the AHI value, and therefore, it may be considered that maxillomandibular setback surgery could significantly increase the AHI value.…”
BackgroundBimaxillary orthognathic surgery with maxillomandibular setback is often accompanied by changes in airway space. We analyzed the changes in airway space before and after surgery and assessed their association with obstructive sleep apnea.MethodsThis study is based on the cohort of 13 adult patients (9 males, 4 females, average age 23.85 years) who underwent bimaxillary orthognathic surgery with maxillomandibular setback.We performed computed tomography and portable polysomnography before and after the surgery to assess changes in airway space and Apnea-Hypopnea Index (AHI) values (total, supine, non-supine).ResultsThe oropharyngeal airway volume decreased by 29% after the surgery, which was statistically significant (p < .05). The upper airway volume and hypopharyngeal airway volume were decreased, but not significantly (4 and 19%, respectively). The changes in airway surface area were statistically significant at all levels examined (p < .05). Changes in the maximum anteroposterior width of the airway were also significant at all levels (p < .05). However, the changes in maximum lateral width were only statistically significant at C2 level (p < .05). AHI values were increased after the surgery but not significantly at any position.ConclusionsAlthough bimaxillary surgery with maxillomandibular setback significantly reduces the airway space, it does not affect AHI values or induce obstructive sleep apnea.
“…Selection of patients requires an extensive preoperative work up including UA imaging to enhance the success rates of the surgery [41,42] . Th ese procedures showed a non-inferior impact in terms of snoring, quality of life and EDS but it was not as good as CPAP in reducing AHI and the degree of oxygen desaturation [43][44][45] .…”
Obstructive sleep apnea is a common sleep disordered breathing condition. It is well recognized as a major risk factor for multiple medical conditions and poor quality of life. It has a great burden on health care resources and a substantial increase in health care use costs. Unfortunately, despite the prevalence, it is widely recognized that it remains under-diagnosed.
Effective treatment needs a comprehensive management plan approach that considers the patient as the centerpiece of management. Regular monitoring and a detailed follow up can have an impact on adherence to therapy. A constant and regular follow up can shed some light on patients who are not compliant with therapy and offer them with alternative therapeutic options that suits them better whenever feasible.
In this review, we aim to shed some light on where we are in terms of obstructive sleep apnea management strategies and options available to each individual patient.
