Caroline Fischer • Judith Lieu (2005) the objective determine if adolescents with unilateral hearing loss (UHL) demonstrate worse language skills than their siblings with normal hearing (NH). Design: Case-control study of 12-17-year-old adolescents with UHL (20 cases) compared with sibling controls with NH (13 controls). Methods: Scores on the oral portion of the Oral and Written Language Scales (OWLS) and the Clinical Evaluation of Language Fundamentals (CELF) were the primary outcome measure. Wechsler's Abbreviated Scales of Intelligence (WASI) scores were also used as an outcome measure. Results: Adolescents with UHL demonstrated worse overall and expressive language scores than controls, (98 vs. 114, P = 0.001; 100 vs. 114, P = 0.006) and…show more content…
(2008).Since the early 1980s, audiologists have become increasingly aware of the potential effect of even mild degrees of hearing loss on the psychoeducational and psychosocial outcomes of children. This review describes some of the key research findings during the past several decades that have led us to our current thinking about unilateral and mild bilateral hearing loss in children. The first section addresses unilateral hearing loss. This is followed by a review of the literature on mild bilateral hearing loss. Specifically, the issues addressed include the significance of permanent mild degrees of hearing loss on children's psychoeducational and psychosocial development and the speech, language, and auditory characteristics of children with mild degrees of hearing loss. Finally, some recommendations regarding the direction of future research are offered. This review is followed by 2 articles summarizing the proceedings of a 2005 workshop convened by the Centers for Disease Control and Prevention (CDC), Early Hearing Detection and Intervention (EHDI) program, and the Marion Downs Hearing Center to address concerns about the under identification of-- and professionals' apparent lack of awareness of permanent unilateral and minimal to mild hearing loss in children.

Conducted a case-control study of 6- to 12-year-old children with UHL compared with sibling controls (74 pairs, n = 148). Scores on the oral portion of the Oral and Written Language Scales (OWLS) were the primary outcome measure. Multivariable analysis was used to determine whether UHL independently predicted OWLS scores after we controlled for potential confounding variables. Children with UHL had worse scores than their siblings on language comprehension (91 vs 98; P = .003), oral expression (94 vs 101; P = .007), and oral composite (90 vs 99; P < .001). UHL independently predicted these OWLS scores when multivariable regression was used with moderate effect sizes of 0.3 to 0.7. Family income and maternal education were also independent predictors of oral expression and oral composite scores. No differences were found between children with right- or left-ear UHL or with varying severity of hearing loss. Children with UHL were more likely to have an individualized education plan (odds ratio: 4.4 [95% confidence interval: 2.0-9.5]) and to have received speech-language therapy (odds ratio: 2.6 [95% confidence interval: 1.3-5.4]).School-aged children with UHL demonstrated worse oral language scores than did their siblings with normal hearing.
