It is well known that mouth breathing is associated with adenotonsillar hypertrophy - which is the main cause of obstructive sleep apnea among children. Despite the importance of this matter, there are only a handful of studies showing the relationship between OSAS and mouth breathing.
to determine the prevalence of obstructive sleep disorders in mouth breathing children and study its correlation with otorhinolaryngological findings.
Retrospective cohort study.
Data analysis from 248 medical charts of mouth breathing children seen at the Pediatric Otolaryngologic Division of a large medical institution between the years of 2000 and 2006. All patients had nasofibroscopy and or Cavum radiographs and polysomnographic exams. According to the Apnea index, patients were classified as primary snorers (AI<1); and as OSAS (>1).
From 248 patients included in the study, 144 (58%) were primary snorers and 104 (42%) had OSAS. The most prevalent otorhinolaryngological findings were adenotonsillar hypertrophy (n=152; 61.2%), tonsilar hypertrophy (n=17; 6.8%), adenoid hypertrophy (n=37; 14.9%), rhinitis (n=155; 62.5%) and secretory otitis (n=36; 14.5%).
primary snoring and OSAS are frequent findings in mouth breathing children. The most frequent otorhinolaryngological disorder in children with OSAS is adenotonsillar hypertrophy with or without rhinitis.
确定张口呼吸儿童阻塞性睡眠障碍的患病率，并研究其与耳鼻喉科发现的相关性。
回顾性队列研究。
对 2000 年至 2006 年间在一家大型医疗机构的儿科耳鼻喉科分部就诊的 248 例张口呼吸儿童的病历进行数据分析。所有患者均接受了鼻纤维镜检查和/或 Cavum 射线照相和多导睡眠图检查。根据呼吸暂停指数，患者被分为单纯性鼾症（AI<1）和阻塞性睡眠呼吸暂停低通气综合征（>1）。
在纳入研究的 248 例患者中，144 例（58%）为单纯性鼾症，104 例（42%）为阻塞性睡眠呼吸暂停低通气综合征。最常见的耳鼻喉科发现是腺样体扁桃体肥大（n=152；61.2%）、扁桃体肥大（n=17；6.8%）、腺样体肥大（n=37；14.9%）、鼻炎（n=155；62.5%）和分泌性中耳炎（n=36；14.5%）。
张口呼吸儿童中，单纯性鼾症和阻塞性睡眠呼吸暂停低通气综合征很常见。阻塞性睡眠呼吸暂停低通气综合征患儿最常见的耳鼻喉科疾病是腺样体扁桃体肥大，伴或不伴鼻炎。
