Introduction: Adenotonsillar hypertrophy (AH) is considered the most common cause of upper respiratory tract obstruction among children. It results in a spectrum of symptoms from mouth breathing, nasal obstruction, hyponasal speech, snoring, and obstructive sleep apnea (OSA) to growth failure and cardiovascular morbidity. Adenotonsillectomy is a typical strategy for patients with AH, but may le...

PURPOSE To examine a potential association between snoring and glaucoma in a population-based setting. METHODS The population-based Beijing Eye Study 2011 included 3468 subjects with an age of 50+ years. The participants underwent a detailed ophthalmic examination. Glaucoma was determined according to the ophthalmoscopic appearance of the optic nerve head. Snoring assessed in an interview was...

OBJECTIVE This technical report describes the procedures involved in developing the recommendations of the Subcommittee on Obstructive Sleep Apnea Syndrome in children. The group of primary interest for this report was otherwise healthy children older than 1 year who might have adenotonsillar hypertrophy or obesity as underlying risk factors of obstructive sleep apnea syndrome (OSAS). The goals...

Snoring is a prevalent disorder affecting 20-40% of the general population. The mechanism of snoring is vibration of anatomical structures in the pharyngeal airway. Flutter of the soft palate accounts for the harsh aspect of the snoring sound. Natural or drug-induced sleep is required for its appearance. Snoring is subject to many influences such as body position, sleep stage, route of breathin...

STUDY OBJECTIVES To identify upper airway changes in snoring using CT scanning, to clarify the snoring mechanism, and to identify the key structures involved. PARTICIPANTS Forty patients underwent CT examination of the head and neck region according to snoring habits; patients were classified into non-snoring (n = 14), moderately loud snoring (n = 13), and loud snoring (n = 13) groups. DESI...

The prevalence of habitual snoring has been extensively explored in paediatric populations. Although exposure to cigarette smoke increases the risk of habitual snoring in a dose-dependent fashion, the potential contribution of air quality to habitual snoring remains unclear. 6000 questionnaires were distributed to 6- to 12-year-old children attending public schools in five distinct neighbourhoo...

OBJECTIVES Patients with obstructive sleep apnea syndrome (OSAS) have impaired responses to inspiratory resistive loading during sleep. This may be due, in part, to a change in the upper airway sensation. Therefore, we hypothesized that patients with OSAS have diminished upper airway sensation due to snoring. METHODS A total of 53 participants were selected based on clinical evaluation and po...

OBJECTIVES This study aimed to investigate the association of asthma-related symptoms with snoring and apnea, and to assess their effects on health-related quality of life (HRQL). DESIGN Population-based cross-sectional study. SUBJECTS AND METHODS A total of 10,224 parents and grandparents of students from 14 randomly selected primary schools in city center were asked to answer questionnair...

OBJECTIVE Current guidelines for the treatment of children with obstructive sleep apnea (OSA) suggest that primary snoring (PS) in children is benign. However, PS has not been well evaluated, and it is unknown whether PS is associated with serious morbidity. This study investigated whether PS is associated with neurobehavioral deficits in children. METHODS Parents of 5- to 7-year-old snoring ...
