Early Otitis Media With Effusion Research Articles

Effect of Ear Infections on Hearing Ability: A Narrative Review on the Complications of Otitis Media.

Otitis media (OM) is an infection that occurs in the middle ear and can affect the structures around the ear, as well as the auditory system. It is one of the most frequent diseases affecting young children each year, especially those aged around six years, due to the anatomical structure and developing immune system.Although some cases of OM resolve spontaneously, children often need medical care since difficulties persist with such infections. The incidence of OM is higher among children than adults, and therefore, their speaking, hearing, and learning capabilities and general development are impaired by recurring middle ear infections.The literature over the last 40 years has documented the impact of early auditory deprivation produced by early OM with effusion (OME) on central auditory processing (CAP). This study aimed to review the impact of acute ear infections on hearing capacity, assess the complications of OM, and document the scientific evidence around the implications of early OME-induced hearing loss in children.Studies have reported the association between hearing loss owing to early OME and alterations in CAP in both children and adolescents. The auditory foundation enables hearing capacity, but this is continually depleted. Therefore, the use of strong antibiotics, sound amplification, hearing rehabilitation, and ear surgery in children must be improved.

Early Otitis Media with Effusion, Hearing Loss, and Auditory Processes at School Age

To examine the effect of conductive hearing loss (HL) secondary to otitis media with effusion (OME) in the first 3 years of life on physiologic, peripheral, and higher-order behavioral auditory measures examined at school age. Peripheral hearing sensitivity for conventional and extended high-frequency audiometric ranges, physiologic (distortion product otoacoustic emissions, contralateral and ipsilateral acoustic middle ear muscle reflexes), auditory brain stem response (ABR), and higher-order auditory processing measures (masking level difference; Virtual Auditory Localization, Speech Intelligibility Gain; adaptive Pediatric Speech Intelligibility task) were examined at the end of the second grade of elementary school in two cohorts (North Carolina, N = 73, and New York, N = 59). All participants (mean age, 8 years) were followed prospectively in infancy and early childhood (7 to 39 months) for middle ear status and hearing loss (using pneumatic otoscopy/tympanometry and repeated conditioned behavioral audiometric response procedures). Multivariate analyses were conducted to address whether early OME and early conductive HL were related to physiologic, peripheral, and higher-order auditory processes. Early hearing loss and OME were significantly associated with peripheral hearing at school age; extended high-frequency thresholds accounted for the result. Similarly, hearing loss in early life and OME were significantly associated with the acoustic middle ear muscle reflex: The contralateral stimulation condition accounted for the association. Significant associations with both early OME and early HL were also found for the auditory brain stem response measure and were explained by the correlations between early hearing loss and the ABR Wave V latency but not other ABR indices. There were no reliable associations between either early OME or early HL on any other auditory processes evaluated at the end of second grade. Extended high-frequency hearing and brain stem auditory pathway measures in childhood were significantly associated with children's experiences with OME and hearing loss from 7 to 39 months of age. However, no significant associations were found for psychoacoustic measures of binaural processing or a behavioral adaptive speech-in-noise test at school age.

The relationship of otitis media in early childhood to attention dimensions during the early elementary school years.

This study examined the impact of otitis media with effusion (OME) and associated hearing loss between 6 and 48 months of age on attention dimensions (i.e., selective/focus, sustained) during the elementary school years. A prospective cohort design in which 74 African American infants were recruited between ages 6 and 12 months. Ear examinations were done repeatedly using both otoscopy and tympanometry, and hearing was assessed using standard audiometric procedures between 6 and 48 months. Multiple measures of attention (i.e., direct assessment, behavioral observations, parent/teacher ratings) were administered from kindergarten through second grade to assess two theoretical dimensions of attention: selective/focused and sustained. The home environment was assessed annually. Results indicated that neither early childhood OME nor hearing loss showed significant correlations with any of the longitudinal or cross-sectional measures of selective/focused attention and sustained attention. In contrast, children with mothers who had fewer years of education and who lived in less responsive and supportive home environments scored higher on both parent and teacher ratings of sustained attention (i.e., hyperactivity) through the second grade of elementary school. For NEPSY Auditory Attention in second grade, a significant interaction between the Home Observation for Measurement of the Environment and hearing loss was uncovered. This interaction showed that children with hearing loss from poor home environments experienced greater difficulties on the NEPSY Auditory Attention task than those with hearing loss from good home environments. These findings do not support a direct linkage of a history of OME and associated hearing loss to difficulties in selective/focused attention or sustained attention in early elementary school children. Relationships between sociodemographic variables and attention-related functions appear stronger and should be considered as mediators in any examination of the linkages between early OME and subsequent attention functions.

Otitis media in childhood in relation to preschool language and school readiness skills among black children.

To examine whether otitis media with effusion (OME) and associated hearing loss (HL) during the first 5 years of life were related to children's language skills during the preschool years and to school readiness skills at entry to kindergarten. In a prospective study, the ears of 85 black children primarily from low-income families and recruited from community-based childcare programs were repeatedly examined from 6 months to 5 years of age for the presence of OME and from 6 months to 4 years of age for HL when well and ill with OME. Assessments were made annually of the children's child-rearing environments at home and in childcare, and children's language skills between 3 and 5 years of age and readiness skills in literacy and math were evaluated at entry into kindergarten. Children had either bilateral or unilateral OME approximately 30.4% and HL 19.6% of the observation time. OME and associated HL were significantly positively correlated with some measures of expressive language at 3 and 4 years of age; however, these direct relationships were no longer significant when the child's gender, socioeconomic status, maternal educational level, and the responsiveness and support of the home and childcare environments were also considered. Further, both OME and HL were moderately correlated with school readiness skills at entry to school, with children having more OME scoring lower in verbal math problems and with children with more HL scoring lower in math and recognizing incomplete words. These associations continued to remain significant even after partialing out the child and family background factors. There was not a significant relationship between children's early OME history or HL and language skills during the preschool years. However, children with more frequent OME had lower scores on school readiness measures. These associations were moderate in degree, however, and the home environment was more strongly related to academic outcomes than was OME or HL. These results should be interpreted cautiously when generalizing to other populations.

Otitis media, fluctuant hearing loss, and speech-language outcomes: a preliminary structural equation model.

The goals of this study were to estimate the risk for lowered speech-language outcomes associated with early recurrent otitis media with effusion (OME) with and without hearing loss and to develop a preliminary descriptive-explanatory model for the findings. Three statistical approaches were used to assess associations among OME, hearing loss, and speech-language outcomes. Participants were a subsample of 70 children followed prospectively in the Dallas Cooperative Project on Early Hearing and Language Development (Friel-Patti & Finitzo, 1990). Findings indicated that hearing levels at 12-18 months were significantly associated with speech delay and low language outcomes at 3 years of age. The risk for subclinical or clinical speech delay at 3 years of age was 2% for children with less than 20 dB average hearing levels at 12-18 months and 33% for children with greater than 20 dB average hearing levels at 12-18 months. A structural equation model (Jöreskog & Sörbom, 1993) indicated that the significant and substantial effects of hearing levels at 12-18 months on speech status at 3 years were significantly mediated by language status at 3 years. Discussion includes implications of these findings for alternative speech perception models linking early OME and hearing loss to later speech-language disorder.

The effects of early bilateral otitis media with effusion on educational attainment: a prospective cohort study.

The relationship between long-lasting, bilateral otitis media with effusion (OME) between the ages of 2 and 4 and educational attainment, in particular, reading and spelling ability at 7 years of age, was studied in a prospective cohort study of 946 children. After selection, three groups were distinguished: 151 children with long-lasting, bilateral OME at preschool age, 37 preschool children treated with ventilation tubes, and 82 children with no history of OME at that age. Early bilateral OME was found to affect spelling ability, but not reading ability, at 7 years. The effects of OME did not appear to increase with the number of observations of OME. Also, recurrent hearing loss did not have more detrimental effects than continuous hearing loss. Effects of treatment with ventilation tubes were not found. Only the teachers' ratings of writing ability indicated a slight advantage of treatment with ventilation tubes. In conclusion, the educational consequences of early OME appear to be very small.

Otitis Media in Early Childhood and Later Language

The relationship between early otitis media with effusion (OME) experience and later language development was examined in a prospective cohort study of 30 children from middle-class families and 33 children from low-income families. Ear status was monitored using otoscopy and tympanometry during wellness and illness periods between birth and 3 years of age. Language was assessed using standardized tests and a language sample between 4 1/2 and 6 years. Findings suggested no reliable relationship between early OME experience and later language development.
