Efficacy and compliance of mandibular repositioning device in obstructive sleep apnea syndrome under a patient-driven protocol of care.

OBJECTIVE: To assess the efficacy and compliance of a traction-based mandibular repositioning device (MRD) for treatment of moderate to severe obstructive sleep apnea syndrome (OSAS) under a patient-driven protocol in a routine outpatient care setting. METHODS: Forty patients, 10 severe and 30 moderate OSAS sufferers (apnea-hypopnea index [AHI] >30 and between 15 and 30, respectively), were enrolled by four sleep centers. Nocturnal polygraphy, quality of life, and quality of sleep questionnaires were used to measure the effect of treatment after 45 days. RESULTS: Thirty-five patients completed the study. Frequency of respiratory events, daytime sleepiness, snoring, patient assessment of sleep quality, specific short-form multipurpose health survey (SF-36) and the Pittsburgh Sleep Quality Index (PSQI) improved significantly with the MRD. Sixty percent of patients were "responders" (>50% decrease in AHI); 46% of patients were "full responders" (>50% decrease and AHI <10). Observance of treatment was high; 80% of patients wore the MRD every night. Side effects and patient complaints were minor and transitory. No serious side effects or cases of pathology aggravation were reported. CONCLUSION: Efficacy on respiratory and somnolence parameters of this innovative traction-based MRD was validated under a simple protocol of care with response rates similar to those published in the literature. This study shows consistent significant improvement by the MRD in quality of life and quality of sleep parameters across several tests. Treatment with the MRD under a simple, patient-driven protocol of care with control of efficacy by nocturnal polygraphy is appropriate in routine outpatient practice for moderate OSAS patients.

French Society of Otorhinolaryngology and Head and Neck Surgery (SFORL) guidelines concerning the role of otorhinolaryngologists in the management of paediatric obstructive sleep apnoea syndrome: Follow-up protocol for treated children.

OBJECTIVES: The authors present the French Society of Oto-Rhino-Laryngology and Head and Neck Surgery (SFORL) clinical practice guidelines concerning the role of otorhinolaryngologists in the management of paediatric obstructive sleep apnoea syndrome (OSAS). This chapter is devoted to the follow-up protocol for children treated for OSAS. METHODS: A multidisciplinary task force was commissioned to carry out a review of the scientific literature on this topic. On the basis of the articles selected and the personal experience of each member of the task force, guidelines were drafted and graded as A, B or C or expert opinion according to a decreasing level of scientific evidence, and were then reviewed by a reading committee, independently of the task force. The final guidelines were established at a consensus meeting. RESULTS: Short-term, medium-term and long-term clinical follow-up and complementary investigations are necessary in view of the risk of residual OSAS, and the risk of recurrence of OSAS related to adenoid and tonsillar regrowth following adenotonsillectomy, the treatment most commonly performed. The modalities of follow-up after surgery, continuous positive airway pressure (CPAP) ventilation, orthodontic treatment, myofascial rehabilitation, and drug therapy are described. The indications for nasal endoscopy and sleep studies as part of follow-up are specified.

Critical role of myofascial reeducation in pediatric sleep-disordered breathing.

BACKGROUND: Limited studies suggest that pubertal development may lead to a recurrence of sleep-disordered breathing (SDB) despite previous curative surgery. Our study evaluates the impact of myofunctional reeducation in children with SDB referred for adenotonsillectomy, orthodontia, and myofunctional treatment in three different geographic areas. METHODS: A retrospective investigation of children with polysomnographic analysis following adenotonsillectomy were referred for orthodontic treatment and were considered for myofunctional therapy. Clinical information was obtained during pediatric and orthodontic follow-up. Polysomnography (PSG) at the time of diagnosis, following adenotonsillectomy, and at long-term follow-up, were compared. The PSG obtained at long-term follow-up was scored by a single-blinded investigator. RESULTS: Complete charts providing the necessary medical information for long-term follow-up were limited. A subgroup of 24 subjects (14 boys) with normal PSG following adenotonsillectomy and orthodontia were referred for myofunctional therapy, with only 11 subjects receiving treatment. Follow-up evaluation was performed between the 22nd and 50th month after termination of myofunctional reeducation or orthodontic treatment if reeducation was not received. Thirteen out of 24 subjects who did not receive myofunctional reeducation developed recurrence of symptoms with a mean apnea-hypopnea index (AHI)=5.3±1.5 and mean minimum oxygen saturation=91±1.8%. All 11 subjects who completed myofunctional reeducation for 24 months revealed healthy results. CONCLUSION: Despite experimental and orthodontic data supporting the connection between orofacial muscle activity and oropharyngeal development as well as the demonstration of abnormal muscle contraction of upper airway muscles during sleep in patients with SDB, myofunctional therapy rarely is considered in the treatment of pediatric SDB. Absence of myofascial treatment is associated with a recurrence of SDB.
