Changes in craniofacial and airway morphology as well as quality of life after passive myofunctional therapy in children with obstructive sleep apnea: a comparative cohort study.

PURPOSE: To examine the craniofacial and airway morphology as well as the quality of life before and after passive myofunctional therapy (PMFT) for 1 year in children with obstructive sleep apnea (OSA). METHODS: Forty children with OSA wearing an oral device nightly (treatment group) and seventeen without the device (control group) were followed up for 1 year. Lateral cephalometric radiography, polysomnography (without participants wearing the oral device), and quality of life survey (OSA-18) were performed before and after the study period. RESULTS: The apnea-hypopnea index (AHI) during sleep, REM AHI, hypopnea count, and desaturation count in the treatment group dropped significantly, compared with the control group. The craniofacial linear measurements increased significantly in both groups, while the length of mandible (Co-Gn) and anterior facial height (N-Me) became significantly larger in the treatment group. For the airway morphology, the intergroup comparison showed that OPha-Ophp (distance between anterior and posterior sides of oropharynx) increased significantly in the treatment group. For quality of life, the intergroup comparison found statistically significant improvements in the following in the treatment group, based on the OSA-18 survey: loud snoring, dysphagia, mood swings, discipline problems, difficulty awakening, total score for the emotional distress portion, and total survey score. CONCLUSIONS: Preliminary evidence is substantiated for the benefits of 1-year PMFT using an oral device with a built-in tongue bead, including improvements in nasal breathing during sleep, mandible linear growth (Co-Gn and N-Me), airway morphology (OPha-Ophp), and patients' quality of life.

Myofunctional Therapy: Role in Pediatric OSA.

Myofunctional therapy (MFT) has been reported to be an alternative treatment to obstructive sleep apnea (OSA), but compliance and long-term outcome in the children were considered as an issue. A prospective study was performed on age-matched children submitted to MFT or to a functional oral device used during sleep (passive MFT) and compared with no-treatment control group. Compliance is a major problem of MFT, and MFT will have to take into consideration the absolute need to have continuous parental involvement in the procedure for pediatric OSA.

Neutral supporting mandibular advancement device with tongue bead for passive myofunctional therapy: a long term follow-up study.

BACKGROUNDS: Myofunctional therapy has been reported to be a valid adjunct treatment to OSA, but compliance was mentioned as an issue. We performed a prospective study on age matched randomized children submitted to myofunctional therapy (MFT) or to a functional device used during sleep (passive MFT). METHODS: 110 children 4 to 16 were recruited for the study, 54 children were in the MFT group [A] while 56 were in the "nocturnal device" group [B]. Clinical evaluation, polysomnography and cephalometric X-Rays were performed at baseline, 6 months and 12 months, with clinical follow-up at 3 months. RESULTS: MFT group show very important absence of compliance, at six months only 23 subjects participated and only 10/23 had been compliant with treatment. None came back for research investigation at 12 months. 48/56 of passive MFT children ended the research protocol at 12 months. Comparison of baseline to 6 and 12 months data showed that all children with passive MFT improved (PSG and cephalometrics) and had nasal breathing during sleep at 1 year, and no negative effect of device were noted. The 10 children compliant with MFT showed clear improvement of sleep related breathing with also changes at cephalometric -X-rays. CONCLUSION: Compliance is a major problem of MFT, and MFT will have to take into consideration the absolute need to have continuous parental involvement in the procedure. Passive MFT gives many more positive results, but potential negative effects of device on other jaw will have to be continuously evaluated.

Passive myofunctional therapy applied on children with obstructive sleep apnea: A 6-month follow-up.

BACKGROUND/PURPOSE: Myofunctional therapy is one of the recommended treatments for obstructive sleep apnea, but the level of compliance has often been low in children. This study aims to investigate the therapeutic effect of passive myofunctional therapy using an oral appliance during sleep in children suffering from obstructive sleep apnea. METHODS: Twenty-nine children who suffered from obstructive sleep apnea were divided into two groups: premature children and full-term children. All children wore an oral device to induce their tongue muscle activity during sleep for 6 months. Polysomnography during sleep was performed before and 1 week after the end of 6-month treatment. RESULTS: Both groups showed positive polysomnographic changes. Full-term children had a significant decrease in the apnea-hypopnea index, hypopnea index, and percentage of arousals. Prematurely born children had a significant decrease in the apnea-hypopnea index during rapid eye movement sleep and in the mean heart rate during sleep. CONCLUSION: Using a specialized oral device to perform myofunctional therapy during sleep may improve the breathing during sleep of children with obstructive sleep apnea.
