Mandibular advancement splint as short-term alternative treatment in patients with obstructive sleep apnea already effectively treated with continuous positive airway pressure.

ABSTRACT: CPAP is used as the first-line treatment for patients with severe OSA, but this machine is not always feasible to use on the long term. We performed a clinical trial to determine whether patients with OSA could use a mandibular advancement splint (MAS) as a short-term treatment alternative to CPAP.Twenty-two patients adherent with CPAP therapy were recruited to the study. Each patient used the MAS for approximately 4 months. The transition between CPAP to MAS was gradual, and patients were asked to start using MAS together with CPAP during the MAS titration until subjective improvement or maximum mandibular advancement was achieved. Sleepiness (ESS), quality of life (SAQLI), and polysomnography were recorded prior to and after MAS titration. Patients recorded CPAP or MAS usage for the following 3 months.Seven women and 12 men with a mean age of 53.8 (± 12.1) years and mean body mass index of 28.1 (± 4.8) kg/m² completed the clinical trial. Prior to MAS, CPAP adherence was 5.8 h/night. AHI decreased significantly with MAS use compared to baseline (30.7 ± 23.1 vs 13.2 ± 11; p < 0.01). Fourteen patients (74%) had > 50% decrease in their AHI, while 2 patients had an increase in their AHI. There were no significant differences in SAQLI between MAS and CPAP treatment, while ESS decreased significantly on MAS. MAS self-reported usage was correlated with treatment efficacy (r = 0.52; p < 0.05). Seventy-five percent of the patients reported being sufficiently satisfied with MAS to continue to use it as an alternative short-term therapy.MAS partially or completely reduced sleep disordered breathing in the majority of selected, successfully CPAP-treated severe OSA patients. Many patients can probably effectively use MAS as a short-term treatment alternative to CPAP.

Project description:Study objectivesObstructive sleep apnea (OSA) is a sleep-related breathing disorder, commonly managed by either continuous positive airway pressure (CPAP) or a mandibular advancement device (MAD). Long-term follow-up and comparison regarding efficacy of these therapies is scarce. In this study the results of treatment, patient adherence, and satisfaction over a 10-year follow-up of these therapies are reported.MethodsThis is a longitudinal follow-up study taken from a subset of patients initially enrolled in a randomized controlled clinical trial of 103 patients with OSA (51 and 52 patients randomized for MAD and CPAP, respectively). After a 10-year follow-up period, 14 patients using MAD and 17 patients using CPAP could be evaluated for this longitudinal follow-up study. Data were analyzed at baseline, after 3 months and at 1-, 2-, and 10-year follow-up. All 31 patients with OSA underwent polysomnography and self-reported measurements.ResultsPolysomnography results showed a favorable outcome of both therapies at 10-year follow-up. At baseline, included patients in both groups did not significantly differ in apnea-hypopnea index (AHI) values. At 10-year follow-up, both the MAD and CPAP groups showed a significant reduction in AHI. At baseline the mean AHI in the MAD group was 31.7 ± 20.6 events/h whereas in the CPAP group it was 49.2 ± 26.1 events/h. At 10-year follow-up the mean AHI in the MAD group was 9.9 ± 10.3 events/h and in the CPAP group it was 3.4 ± 5.4 events/h. Both therapies resulted in a substantial improvement in self-reported neurobehavioral outcomes at 10-year follow-up.ConclusionsBoth CPAP and MAD therapy demonstrate good and stable treatment effects after a 10-year follow-up period. Therefore, when indicated, both therapies are appropriate modalities for the long-term management of OSA.Clinical trial registrationRegistry: Netherlands Trial Register; Name: Management of the Obstructive Sleep Apnea-Hypopnea Syndrome: Oral Appliance versus Continuous Positive Airway Pressure Therapy; Identifier: NL75; URL: https://www.trialregister.nl/trial/75.

Project description:Study objectivesIt has been suggested that treatment for obstructive sleep apnea (OSA) reduces cardiovascular risk. So far, knowledge is limited about the difference in the reduction of this risk between mandibular advancement device (MAD) and continuous positive airway pressure (CPAP) therapy. The aim of this study was to compare the cardiovascular effects of MAD vs CPAP therapy in patients with moderate OSA.MethodsPatients with an apnea-hypopnea index of 15-30 events/h were randomized to either MAD or CPAP therapy. At baseline and after 12-month follow-up, 24-hour ambulant blood pressure measurements and laboratory measurements were performed. Ambulant blood pressure measurements consisted of 24-hour, daytime and night-time systolic and diastolic blood pressure and heart rate measurements. Laboratory measurements consisted of serum lipid values, creatinine, high-sensitivity C-reactive protein, plasma glucose, hemoglobin A1c glycated hemoglobin, proinflammatory cytokines, soluble receptor for advanced glycation end-products, chemokines, and adhesion molecules.ResultsOf the 85 randomized patients with moderate OSA, data were available for 54 patients (n = 24 MAD, n = 30 CPAP) at 12-month follow-up and showed that apnea-hypopnea index significantly decreased with either therapy. In the MAD group, soluble receptor for advanced glycation end-products and glycated hemoglobin were significantly higher after 12 months' follow-up compared to baseline. No significant changes were found between MAD and CPAP treatments for all outcomes.ConclusionsTreatment of patients with moderate OSA with either MAD or CPAP therapy had no profound effects on major cardiovascular risk factors after 12 months.Clinical trial registrationRegistry: ClinicalTrials.gov; Title: MRA Therapy vs CPAP Therapy in Moderate OSAS; Identifier: NCT01588275; URL: https://clinicaltrials.gov/ct2/show/NCT01588275.CitationUniken Venema JAM, Knol-de Vries GE, van Goor H, Westra J, Hoekema A, Wijkstra PJ.
