“…10 Positional OSA, traditionally defi ned as supine AHI ≥ twice that of non-supine postures, has a prevalence of 50% to 60%. 7,11,12 According to a more recent and stringent defi nition requiring a supine AHI ≥ twice that of non-supine AHI and normalization of AHI in non-supine postures, 13 positional OSA patients who meet these criteria should remain within normal limits by using effective positional therapy alone to simply avoid supine sleep.

Study Objectives: Approximately 30% of obstructive sleep apnea (OSA) patients have supine-predominant OSA, and simply avoiding supine sleep should normalise respiratory disturbance event rates. However, traditional supineavoidance therapies are inherently uncomfortable, and treatment adherence is poor and diffi cult to monitor objectively. This study evaluated the effi cacy of a novel, potentially more acceptable position monitor and supine-avoidance device for managing supine-predominant OSA and snoring. Design and Setting: In-laboratory evaluation of position recording accuracy versus video recordings (validation study), and randomized controlled crossover trial of active versus inactive supine-avoidance therapy in the home setting (effi cacy study). Patients: 17 patients undergoing in-laboratory sleep studies (validation) and 15 patients with supine-predominant OSA (effi cacy). Interventions: Effi cacy study: 1 week of inactive and 1 week of active treatment in randomized order, separated by 1 week. Measurements and Results: Agreement between 30-sec epoch-based posture classifi cations from device versus video records was high (median κ 0.95, interquartile range: 0.88-1.00), and there was good supine time agreement (bias 0.3%, 95%CI: −4.0% to 4.6%). In the effi cacy study, apnea-hypopnea index (AHI) and snoring frequency were measured in-home using a nasal pressure and microphone based system during inactive and active treatment weeks. The position monitoring and supine alarm device markedly inhibited supine time (mean ± SEM 19.3% ± 4.3% to 0.4% ± 0.3%, p < 0.001) and reduced AHI (25.0 ± 1.7 to 13.7 ± 1.1 events/h, p = 0.030) but not snoring frequency.

“…13,14 Snoring is a cardinal feature of OSA and results from vibrations of a partially obstructed upper airway during sleep. 15 Snoring may have deleterious health consequences in its own right, including vibration damage-induced carotid atherosclerosis 16,17 and potentially carotid plaque rupture and stroke.…”

“…Positional obstructive sleep apnea syndrome (POSAS) occurs in approximately 56% of patients with obstructive sleep apnea syndrome (OSAS) (1) independently from body habitus (2). Furthermore, respiratory pauses are more severe when lying supine in over 70% of subjects with mild to moderate OSAS (3).…”

RESUMOO presente trabalho tem por objetivo relatar um caso clínico diagnosticado como Síndrome da apnéia obstrutiva do sono, e expor uma sequência lógica para o tratamento de pacientes que sofrem desta doença. Através da interpretação do exame de polissonografia, da anamnese, exame clínico e, ainda, por meio da realização do traçado e análise cefalométrica para apnéia do sono, indicou-se de forma segura e efetiva a terapia com aparelho intra-oral. Desta maneira, foi confeccionado um aparelho de avanço mandibular, o PLG. Após quatro semanas de uso do aparelho, o paciente foi encaminhado à realização de uma nova polissonografia, a qual revelou ausência de apnéias obstrutivas durante o sono. As etapas seguidas no tratamento deste estudo de caso destacaram a importância e a necessidade de uma abordagem correta e criteriosa dos casos de pacientes com apnéia do sono encaminhados ao consultório odontológico. A abordagem e sequência apresentadas garantiram o sucesso no tratamento deste estudo de caso. Obstructive episodes are usually accompanied by loud snoring and a drop in blood oxygen saturation (hypoxemia), ending in short micro-awakenings, which result in sleep fragmentation 4 . Sleep basically consists of two moments that alternate between waking states: non-rapid eye movement (NREM) and rapid eye movement (REM). Sleep apnea events last longer and have higher hypoxemia during REM sleep than during NREM sleep in patients with OSAS 5 . Termos de indexação:According to Jauhar et al. 2 , the deterioration of sleep quality caused by OSAS significantly contributes to excessive daytime sleepiness, loss of cognitive capacity, and mood swings and personality changes. It has also been associated with a worsening in the quality of life and in relationships with spouses and partners, decreased alertness, and an increased risk of traffic accidents. In addition, there are indications of an increase in cardiovascular diseases among untreated OSAS patients, and it is a potentially life-threatening condition 1,3,[6][7] that requires an early diagnosis and effective treatment.
