OBJECTIVE 1) Share our experiences treating patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) with titratable and nontitratable thermoplastic mandibular advancement devices (MADs) fitted in our otolaryngology clinic. 2) Compare these devices in terms of objective response (OR), as defined by a > or = 50 percent decrease in baseline apnea-hypopnea index (AHI) and an AHI < 20, and s...

Obstructive sleep apnea (OSA) is a disorder characterized by repeated pauses in breathing during sleep, which leads to deoxygenation and voiced chokes at the end of each episode. OSA is associated by daytime sleepiness and an increased risk of serious conditions such as cardiovascular disease, diabetes, and stroke. Between 2 and 7% of the adult population globally has OSA, but it is estimated t...

SNORING AND OBSTRUCTIVE SLEEP APNEA (OSA) ARE CAUSED IN PART BY REPETITIVE DYNAMIC OBSTRUCTION OF THE OROPHARYNGEAL AIRWAY. There is growing epidemiological and experimental evidence that OSA, and to a lesser degree snoring, are associated with a wide variety of adverse health outcomes.1, 2 OSA is considered one of several potentially treatable contributors to systemic hypertension, and has bee...

Sleep apnea-hypopnea syndrome (SAHS) consists of recurrent episodes in which the airflow becomes limited during sleep, a consequence of anatomo-functional abnormalities of the upper airway (UA) that lead to its collapse. This leads to a reduction in oxyhemoglobin saturation (SaO2) and causes arousals from sleep. The symptoms of this syndrome include the sensation of not having been refreshed by...

This study was undertaken in an attempt to characterize the acoustic properties of snoring sounds in the time and frequency domains, and to correlate between these properties and the mechanical events underlying their production. Three experimental set-ups were used: 1) Dog model--six mongrel dogs, in which partial upper airway obstruction was created by an implanted supraglottic balloon. Flow,...

lip and palate (CLP)1 compared with those in normal subjects; patients with CLP have a smaller upper airway compared with normal controls.2,3 Parents of children with CLP have often reported that their children snore and breathe noisily during sleep, and patients with reduced nasal airways are also predisposed to mouth breathing.4-6 Rose et al7 found that patients with cleft palate had signific...

A dynamic interplay is known to exist between auditory processing and human cognition. For example, prior investigations of speech-in-noise have revealed there is more to learning than just listening: Even if all words within a spoken list are correctly heard in noise, later memory for those words is typically impoverished. These investigations supported a view that there is a "gap" between the...

OBJECTIVE The prevalence of obstructive sleep apnea-hypopnea syndrome (OSAHS) in the general pediatric population ranges from 1% to 3%. However, its prevalence in an unselected population of obese children is unknown. We studied the association between obesity and OSAHS in children diagnosed with the syndrome in a cohort of boys and girls (age range, 2-14 years) referred to the pediatric respir...

BACKGROUND Sleep-Disordered Breathing (SDB) varies from habitual snoring to partial or complete obstruction of the upper airway and can be found in up to 10% of children. SDB can significantly affect children's wellbeing, as it can cause growth disorders, educational and behavioral problems, and even life-threatening conditions, such as cardiorespiratory failure. Adenotonsillectomy represents t...

STUDY OBJECTIVES To determine the prevalence of habitual snoring (HS) in 1-year-old children, and to assess the relationship between HS and atopic status in these children. DESIGN Cross-sectional evaluation of a birth cohort selected from the population. SETTING Ohio and Kentucky River Valley communities. PARTICIPANTS Children participating in the Cincinnati Childhood Allergy and Air Poll...
