Auditory Deprivation Caused By Early Otitis Media with Effusion
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2018, Vol 5, Issue 1
Abstract
Introduction: In the past 40 years, the literature has attempted to clarify the evidence on the effect of early auditory deprivation caused by early otitis media with effusion (OME) on central auditory processing (CAP). Objective: The aim of this study was to evaluate the scientific evidence on the effects of auditory deprivation caused by early OME on the CAP of children and adolescents. Data Synthesis: A systematic search was conducted in the following databases: Scientific Electronic Library Online (Scielo), Latin American and Caribbean Health Sciences (Literatura Latino-Americana e do Caribe em Ciências da Saúde–LILACS), PubMed, Scopus, and Web of Science, PubMed, Medline, and Cochrane databases from the earliest publication, up until October 2016. Prospective studies that reported children or adolescents (aged less than 18 years) with early OME in the first years of life. Conclusions: We selected eight studies on the research topic. The results indicated a correlation between auditory deprivation caused by early OME and changes in CAP in children and adolescents. The hearing ability that was consistently susceptible to auditory deprivation was the auditory figure-ground. Otitis media with effusion (OME) is a middle-ear inflammation characterized by the presence of fluid in the middle ear without signs or symptoms of acute infection and perforation of the tympanic membrane [1]. This condition reduces the mobility of the tympanic membrane and limits the transmission of sound waves [2]. The high prevalence of OME in early childhood has generated speculation about its effect on the development of the human auditory system because this condition is the most common reason for medical consultations and surgeries in children 3. When it affects children in the first five years of life, it can be considered “early” [3,4]. It is believed that temporary and fluctuating hearing loss caused by the disease at this stage of life may impair hearing development [3-5] and is considered a form of auditory deprivation [6]. The first study that described a probable association between early auditory deprivation and changes in auditory development in the long term dates from 1962. This case report described the effects of auditory deprivation on the late behavior of a patient [7]. Since then, several studies [3-6,8-13] have attempted to elucidate the effect of early auditory deprivation caused by early OME on central auditory processing (CAP) in the long term. However, despite the large number of studies published in the past 40 years, many controversies persist [13,14]. These controversies are criticized by several authors because most of these studies were retrospective [3,5,15,16] which limited the establishment of a precise correlation between the disease and outcomes 3. Therefore, longitudinal studies are needed to see if the negative effects of early OME persist after the recovery of tonal auditory thresholds [16].
