    Co-Authors: Chenghui Lin, Weichih Chin, Yushu Huang, Pofang Wang, Paola Pirelli, Yenhao Chen, Christian Guilleminault
    Abstract:

    Abstract Study objectives To evaluate the objective and subjective long-term outcome of Maxillomandibular Advancement (MMA) in Far-East Asian patients with moderate to severe obstructive sleep apnea (OSA). Methods This is a long-term follow-up study to evaluate the treatment outcome of MMA in OSA patients by objective polysomnography (PSG) and subjective questionnaires (Pittsburgh Sleep Quality Index-PSQI, Insomnia Severity Index-ISI, Beck Anxiety Inventory-BAI, Beck Depression Inventory-BDI, Epworth Sleepiness scale-ESS, and Short Form-36 Quality of Life–SF–36). Evaluation was done before surgery and we followed these patients one and two years after surgery. We also assessed the neurocognitive function by Continuous performance test (CPT) and Wisconsin Card Sorting Test (WCST) before and after MMA. Results A total of 82 patients with OSA (female = 19) were enrolled and 53 participants (75.7% men, age 35.66 ± 11.66 years [mean ± SD], BMI = 24.80 ± 3.29) completed the two-year follow-up. The apnea-hypopnea index (AHI) decreased from a mean of 34.78 ± 26.01 to 3.61 ± 2.79 and 7.43 ± 6.70 events/hour (p = 0.007) at the first and second year evaluation. There was significant improvement in PSG (especially respiratory profile), questionnaires (PSQI and ISI total score), and neurocognitive testing (attention and executive function) after MMA. Meanwhile, no major complication such as avascular necrosis of bonny segments, facial nerve injury, blindness or compromise of airway was found after surgery. Conclusions MMA is a clinically effective treatment for patients with moderate-to-severe OSA as demonstrated by significant long-term decrease in AHI and improvement in neurocognitive testing.

    Abstract:

    Importance Maxillomandibular Advancement (MMA) is an invasive yet effective surgical option for obstructive sleep apnea (OSA) that achieves enlargement of the upper airway by physically expanding the facial skeletal framework. Objective To identify criteria associated with surgical outcomes of MMA using aggregated individual patient data from multiple studies. Data Sources The Cochrane Library, Scopus, Web of Science, and MEDLINE from June 1, 2014, to March 16, 2015, using the Medical Subject Heading keywords Maxillomandibular Advancement , orthognathic surgery , maxillary osteotomy , mandibular Advancement , sleep apnea , surgical , surgery , sleep apnea syndrome , and obstructive sleep apnea. Study Selection Inclusion criteria consisted of studies in all languages of (1) adult patients who underwent MMA as treatment for OSA; (2) report of preoperative and postoperative quantitative outcomes for the apnea-hypopnea index (AHI) and/or respiratory disturbance index (RDI); and (3) report of individual patient data. Studies of patients who underwent adjunctive procedures at the time of MMA (including tonsillectomy, uvulopalatopharyngoplasty, and partial glossectomy) were excluded. Data Extraction Three coauthors systematically reviewed the articles and updated the review through March 16, 2015. The PRISMA statement was followed. Data were pooled using a random-effects model and analyzed from July 1, 2014, to September 23, 2015. Main Outcomes and Measures The primary outcomes were changes in the AHI and RDI after MMA for each patient. Secondary outcomes included surgical success, defined as the percentage of patients with more than 50% reduction of the AHI to fewer than 20 events/h, and OSA cure, defined as a post-MMA AHI of fewer than 5 events/h. Results Forty-five studies with individual data from 518 unique patients/interventions were included. Among patients for whom data were available, 197 of 268 (73.5%) had undergone prior surgery for OSA. Mean (SD) postoperative changes in the AHI and RDI after MMA were −47.8 (25.0) and −44.4 (33.0), respectively; mean (SE) reductions of AHI and RDI outcomes were 80.1% (1.8%) and 64.6% (4.0%), respectively; and 512 of 518 patients (98.8%) showed improvement. Significant improvements were also seen in the mean (SD) postoperative oxygen saturation nadir (70.1% [15.6%] to 87.0% [5.2%]; P P Conclusions and Relevance Maxillomandibular Advancement is an effective treatment for OSA. Most patients with high residual AHI and RDI after other unsuccessful surgical procedures for OSA are likely to benefit from MMA.

  • Maxillomandibular Advancement for the treatment of obstructive sleep apnea a systematic review and meta analysis
    Sleep Medicine Reviews, 2010
    Co-Authors: Jonerik C Holty, Christian Guilleminault
    Abstract:

    The reported efficacy of Maxillomandibular Advancement (MMA) for the treatment of obstructive sleep apnea (OSA) is uncertain. We performed a meta-analysis and systematic review to estimate the clinical efficacy and safety of MMA in treating OSA. We searched Medline and bibliographies of retrieved articles, with no language restriction. We used meta-analytic methods to pool surgical outcomes. Fifty-three reports describing 22 unique patient populations (627 adults with OSA) met inclusion criteria. Additionally, 27 reports provided individual data on 320 OSA subjects. The mean apnea-hypopnea index (AHI) decreased from 63.9/h to 9.5/h (p<0.001) following surgery. Using a random-effects model, the pooled surgical success and cure (AHI <5) rates were 86.0% and 43.2%, respectively. Younger age, lower preoperative weight and AHI, and greater degree of maxillary Advancement were predictive of increased surgical success. The major and minor complication rates were 1.0% and 3.1%, respectively. No postoperative deaths were reported. Most subjects reported satisfaction after MMA with improvements in quality of life measures and most OSA symptomatology. We conclude that MMA is a safe and highly effective treatment for OSA.

  • obstructive sleep apnea and Maxillomandibular Advancement an assessment of airway changes using radiographic and nasopharyngoscopic examinations
    Journal of Oral and Maxillofacial Surgery, 2002
    Co-Authors: Christian Guilleminault, Robert Riley, Nelson B. Powell
    Abstract:

    Purpose: The study aim was to evaluate the resultant changes in the upper airway after Maxillomandibular Advancement (MMA) for obstructive sleep apnea. Methods: Twelve patients were evaluated before and after MMA using fiberoptic nasopharyngoscopy (NPG) with Muller maneuver. An inspiratory force meter was used to ensure the consistency of the inspiratory efforts between the 2 examinations. Preoperative and postoperative lateral cephalometric radiographs were also compared. Results: Decrease in the airway obstruction was shown by the lateral cephalometric radiograph as well as by fiberoptic NPG during passive respiration. Fiberoptic NPG with Muller maneuver also revealed a decrease in airway collapsibility. Although the retrodisplacement of the tongue base was improved, the improvement in lateral pharyngeal wall stability was the most striking. Conclusions: MMA achieved expansion of the upper airway. In addition, MMA decreased the collapsibility of the airway, especially the lateral pharyngeal walls. These findings may explain the highly successful outcomes of MMA for the treatment of obstructive sleep apnea. © 2002 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 60:526-530, 2002

    British Inst Radiology, 2015
    Co-Authors: Fb Prado, De Moraes M., Ac Rossi, Ar Freire, Fc Groppo, Caria Phf
    Abstract:

    Objectives: The purpose of this study was to cephalometrically evaluate the pharyngeal airway space and frontal and sphenoid sinus changes after Maxillomandibular Advancement counterclockwise rotation for class II anterior open bite malocclusion. Methods: The study included 49 patients (98 lateral teleradiographs; 36 females and 13 males) who were analysed in the pre-operative (1 week before surgery) and post-operative (6 months after surgery) periods. In each lateral teleradiography, the dimensions of the inferior and superior pharyngeal airway space, TB-PhW1 [the point between the posterior aspect of the tongue to the dorsal pharyngeal wall (oropharynx) (TB) and the point on the dorsal pharyngeal wall closest to TB (PhW1)] and UP-PhW2 [and the point between the posterior aspect of the soft palate to the dorsal pharyngeal wall (nasopharynx) (UP) (PhW2)] measurements were evaluated, as well as the dimensions of the frontal and sphenoid sinuses. The differences between the two operative times were evaluated by Student's t-test. Results: All measurements showed excellent reproducibility for the intraclass correlation coefficient (ICC > 0.9; p < 0.0001). There was an increase in the measurements TB-PhW1 and UP-PhW2 and a decrease in the dimensions of the frontal and sphenoid sinuses after orthognathic surgery. Conclusions: The morphology of the superior and inferior pharyngeal airway space and frontal and sphenoid sinuses changes after 6 months of Maxillomandibular Advancement counterclockwise rotation for class II anterior open bite malocclusion.

  • uvulopalatopharyngoplasty Maxillomandibular Advancement and the velopharynx
    Laryngoscope, 2001
    Co-Authors: Robert J Troell, Robert Riley, Nelson B. Powell, Uta Koester, Christian Guilleminault
    Abstract:

    Objective To evaluate the presence of velopharyngeal insufficiency (VPI) symptoms and the associated changes of the velopharyngeal anatomy in patients who underwent Maxillomandibular Advancement (MMA) for persistent obstructive sleep apnea (OSA) after uvulopalatopharyngoplasty (UPPP). Methods Preoperative and postoperative cephalometric radiographs were analyzed to assess the anatomic changes of the velopharynx. In addition, a questionnaire survey was sent to the patients between 6 to 12 months after MMA. The questionnaires evaluated the presence and extent of VPI symptoms, including nasal regurgitation while eating or drinking as well as hypernasal speech. A 10-cm visual analog scale (VAS 0-10) was included to assess the impact of VPI symptoms on the patient's quality of life. In the patients who reported VPI symptoms, telephone interviews were conducted 1 year after the survey to evaluate the changes in VPI symptoms over time. Results Fifty-two of the 65 questionnaires were returned. Five patients (9.6%) reported nasal regurgitation of liquids when drinking hastily, with 2 patients reporting the occurrences as occasional and 3 patients reporting as rare. The impact of these symptoms on the patient's quality of life was minimal (VAS 0.6 ± 0.4). Regurgitation of food or hypernasal speech was not reported. The telephone interviews 1 year later revealed that the symptoms have completely resolved in all 5 patients. Comparison of the preoperative and postoperative cephalometric radiographs demonstrated the pharyngeal depth increase was 48% of the amount of maxillary Advancement and the functional pharyngeal length increased 53% of the maxillary Advancement. The functional depth of the pharynx after MMA was significantly greater in the patients with VPI symptoms (P = .01). Conclusion The results of this study suggest that patients who undergo MMA for persistent OSA after UPPP have a low risk of developing VPI. If symptoms occur postoperatively, they are mild and have minimal effect on the patient's quality of life; moreover, the symptoms usually resolve over time.

  • Maxillomandibular Advancement versus multilevel surgery for treatment of obstructive sleep apnea a systematic review and meta analysis
    Sleep Medicine Reviews, 2021
    Co-Authors: Ning Zhou, Madeline J L Ravesloot, Nico De Vries, Zhengfei Huang, Rene Spijker, Ghizlane Aarab, Frank Lobbezoo, J De Lange
    Abstract:

    Summary Multilevel surgery (MLS) and Maxillomandibular Advancement surgery (MMA) are two established options in surgical management of obstructive sleep apnea (OSA), which target different levels of airway obstruction. The objective of this review was to comparatively evaluate the clinical efficacy and safety of MMA and MLS in the treatment of OSA. MEDLINE and Embase databases were searched for studies on MMA and/or MLS in OSA patients. Twenty MMA studies and 39 MLS studies were identified. OSA patients who underwent MMA showed significant improvements in AHI, LSAT, ODI, and ESS by −46.2/h, 13.5%, −30.3/h, and −8.5, respectively. The pooled rates of surgical success and cure for MMA were 85.0% and 46.3%, respectively. Patients who underwent MLS showed significant improvements in AHI, LSAT, ODI, and ESS by −24.7/h, 8.7%, −19.1/h, and −5.8, respectively. The pooled surgical success and cure rates for MLS were 65.1% and 28.1%, respectively. The rates of major complication of MMA and MLS were 3.2% and 1.1%, respectively, and the rate of minor complication of MMA was higher than that of MLS. We conclude that both MMA and MLS are effective treatment options for OSA. Compared to MLS, MMA may be more effective in improving OSA. However, the complication rate of MMA is higher.

  • assessment of obstructive sleep apnoea treatment success or failure after Maxillomandibular Advancement
    International Journal of Oral and Maxillofacial Surgery, 2017
    Co-Authors: M H T De Ruiter, R C Apperloo, Dan M J Milstein, J De Lange
    Abstract:

    Maxillomandibular Advancement (MMA) is an alternative therapeutic option that is highly effective for treating obstructive sleep apnoea (OSA). MMA provides a solution for OSA patients that have difficulty accepting lifelong treatments with continuous positive airway pressure or mandibular Advancement devices. The goal of this study was to investigate the different characteristics that determine OSA treatment success/failure after MMA. The apnoea–hypopnoea index (AHI) was used to determine the success or failure of OSA treatment after MMA. Sixty-two patients underwent MMA for moderate and severe OSA. A 71% success rate was observed with a mean AHI reduction of 69%. A statistically significant larger neck circumference was measured in patients with failed OSA treatments following MMA (P = 0.008), and older patients had failed OSA treatments with MMA: 58 vs. 53 years respectively (P = 0.037). Cephalometric analysis revealed no differences between successful and failed OSA treatment outcomes. There was no difference in maxillary and mandibular Advancements between success and failed MMA-treated OSA patients. The complications most frequently reported following MMA were sensory disturbances in the inferior alveolar nerve (60%) and malocclusion (24%). The results suggest that age and neck girth may be important factors that could predict susceptibility to OSA treatment failures by MMA

  • residual posa after Maxillomandibular Advancement in patients with severe osa
    Positional therapy in obstructive sleep apnea, 2015
    Co-Authors: Linda B L Benoist, J De Lange, Maurits H T De Ruiter, Nico De Vries
    Abstract:

    In patients with severe or extreme OSA and CPAP failure, Maxillomandibular Advancement (MMA) can be considered. Because of its considerable morbidity, MMA is mostly reserved for severe to extreme cases, often after less aggressive surgeries have failed. The success rates of MMA are very high: between 80 and 90 %. A new finding is that MMA failure can be due to the fact that after surgery the AHI in supine sleep position remains much higher as compared to the non-supine AHI: in other words, non-positional OSA has reversed into less severe POSA. Postoperative residual POSA can be in theory a good indication for additional positional therapy. In this chapter we will discuss our theoretical considerations on this phenomenon of residual POSA after MMA surgery.

    Co-Authors: Fb Prado, De Moraes M., Ac Rossi, Ar Freire, Fc Groppo, Caria Phf
    Abstract:

    Objectives: The purpose of this study was to cephalometrically evaluate the pharyngeal airway space and frontal and sphenoid sinus changes after Maxillomandibular Advancement counterclockwise rotation for class II anterior open bite malocclusion. Methods: The study included 49 patients (98 lateral teleradiographs; 36 females and 13 males) who were analysed in the pre-operative (1 week before surgery) and post-operative (6 months after surgery) periods. In each lateral teleradiography, the dimensions of the inferior and superior pharyngeal airway space, TB-PhW1 [the point between the posterior aspect of the tongue to the dorsal pharyngeal wall (oropharynx) (TB) and the point on the dorsal pharyngeal wall closest to TB (PhW1)] and UP-PhW2 [and the point between the posterior aspect of the soft palate to the dorsal pharyngeal wall (nasopharynx) (UP) (PhW2)] measurements were evaluated, as well as the dimensions of the frontal and sphenoid sinuses. The differences between the two operative times were evaluated by Student's t-test. Results: All measurements showed excellent reproducibility for the intraclass correlation coefficient (ICC > 0.9; p < 0.0001). There was an increase in the measurements TB-PhW1 and UP-PhW2 and a decrease in the dimensions of the frontal and sphenoid sinuses after orthognathic surgery.
