“…In this study, pre-and post-operative CBCT scans of 20 patients with OSA who had been treated with MMA-surgery were analyzed. A statistically significant increase in the 3D airway volume of the pharynx was found, which concurs with previous studies 18,19,20 . There was, however, great individual variation between patients: airway volume increased in every patient, but in some patients the increase was very significant, whereas in others only slight improvement occurred.…”

To study volumetric changes in the upper airway in obstructive sleep apnea (OSA) patients after maxillomandibular advancement (MMA) and compare findings to polysomnography (PSG) data of the same patients. Patients and Methods Study consisted of 20 OSA patients (mean age 48 years, range 31-59 years, 1 female, 19 male). Mean SNB and SNA angles before surgery indicated mandibular and maxillary retrognathia. All were treated with MMA including pre-and post-operative orthodontics. Pre-and post-treatment cone-beam computed tomograms (CBCT) were used to measure upper airway volume and PSG data to examine apnea-hypopnea index (AHI), oxygen desaturation index (ODI3/ODI4). In addition, Epworth Sleepiness Scale (ESS), General Health Questionnaire (GHQ-12) and amount of MMA was collected from patient´s files. Results Mean maxillary and mandibular advancement was 4.6±1.9 mm and 9.3±1.7 mm, respectively. Statistically significant increase (mean 64.1%) in the airway volume was found with large individual variation. ODI3/ODI4 and AHI values improved statistically significantly from pre-to post-surgery. ODI3/ODI4 reduced from 12.3±9.8 to 4.0±4.2 and AHI 21.4±13.8 to 5.8±7.2. ESS scores improved (lower scores) post-surgery for majority of patients (n=15) while GHQ-12 scores improved (lower scores) in only six patients. Conclusion Maxillo-mandibular advancement increases upper airway volume and reduces OSA symptoms studied by PSG. MMA can be considered as curative treatment for OSA; however, residual AHI can be found in many patients.

Obstructive sleep apnea is an exciting area for orthodontists to be involved. The level of awareness of sleep apnea and related health issues is growing rapidly. The demand of integrating sleep into the orthodontic practice shortly will be driven by the need of the societies as some of our patients will be shortly coming into our offices aware of sleep apnea. However, with our busy clinical orthodontic practice, the need of condense short review become more demanding. Therefore, this review will try to summarize the clinical and orthodontic observation in the diagnoses of adult obstructive sleep apnea with clinical application in orthodontic practice.

“…Previous research has proven that BSSRO advance mandibular for treating retrognathism could improve PAS. [7][8] However, some studies have shown that mandibular setback had been associated with a decrease in the PAS postoperatively, and in some cases was even a potential for the development of obstructive sleep apnea (OSA). [9][10][11] Body mass index (BMI), a numerical computation based on height and weight, is used to categorize a person as either underweight, normal weight, overweight, or obese.…”
