title: Obstructive sleep apnea and oral language disorders.
abstract: BACKGROUND
  Children and adolescents with obstructive sleep apnea (OSA) may have consequences, such as daytime sleepiness and learning, memory, and attention disorders, that may interfere in oral language.
  
  
  OBJECTIVE
  To verify, based on the literature, whether OSA in children was correlated to oral language disorders.
  
  
  METHODS
  A literature review was carried out in the Lilacs, PubMed, Scopus, and Web of Science databases using the descriptors "Child Language" AND "Obstructive Sleep Apnea". Articles that did not discuss the topic and included children with other comorbidities rather than OSA were excluded.
  
  
  RESULTS
  In total, no articles were found at Lilacs, 37 at PubMed, 47 at Scopus, and 38 at Web of Science databases. Based on the inclusion and exclusion criteria, six studies were selected, all published from 2004 to 2014. Four articles demonstrated an association between primary snoring/OSA and receptive language and four articles showed an association with expressive language. It is noteworthy that the articles used different tools and considered different levels of language.
  
  
  CONCLUSIONS
  The late diagnosis and treatment of obstructive sleep apnea is associated with a delay in verbal skill acquisition. The professionals who work with children should be alert, as most of the phonetic sounds are acquired during ages 3-7 years, which is also the peak age for hypertrophy of the tonsils and childhood OSA.
