Abstract
PURPOSE OF REVIEW The purpose of this review is to provide an update on current literature as it relates to the impact of unilateral hearing loss for the pediatric population. RECENT FINDINGS Current studies further corroborate past research findings which reveal the potential consequences of unilateral hearing loss on spatial hearing, language, and neurocognitive functioning. Deficits among children with unilateral hearing loss may parallel those seen in children with bilateral hearing loss, further challenging historic views that hearing in one ear in childhood is sufficient for normal development. The potential deficiencies seen in children with unilateral hearing loss can be subtler than those seen with bilateral hearing loss, but may nonetheless also impact school performance, patient fatigue, parental stress, and quality of life. Early interventions within a sensitive period of development of the central auditory system may circumvent potential barriers in cognitive, academic, and psychosocial development. SUMMARY This review synthesizes the latest research on the impact of unilateral hearing loss in childhood and the role for possible interventions. The summarized information may serve to support the development of new guidelines for the evaluation and treatment of children with unilateral hearing loss.

Abstract
Children with unilateral or mild bilateral hearing loss are increasingly identified in early childhood. Relatively little is known about how hearing loss affects their developmental trajectory or whether it contributes to parenting stress for these parents. This study aimed to examine child behavior and parenting stress in parents of children with unilateral/mild bilateral hearing loss compared to children with typical hearing. This prospective study involved 54 children with unilateral/mild bilateral hearing loss identified at a median age of 4.5 months (IQR 2.6, 6.5) and 42 children with typical hearing. At age 48 months, child behavior and parenting stress were measured. Auditory and language results were also analyzed in relation to child behavior and parenting stress. Parents of these children did not report significantly more parenting stress or behavior problems than parents of children with typical hearing. However, both parenting stress and child behavior were related to functional hearing in noise.

Abstract
OBJECTIVE Hearing loss is an important health concern in Canada's Arctic. The objective of this research was to provide information on the prevalence of childhood hearing loss in Nunavut. DESIGN This cross-sectional study involved comprehensive audiologic assessments of school-aged children in six communities to determine overall and community-specific prevalence of hearing loss. Data were collected about hearing aid use and factors affecting use through a parent questionnaire. STUDY SAMPLE Assessments were completed for 644 children in kindergarten to grade 6. RESULTS 124 (19.3%) children had hearing loss of ≥ 30 dB HL at one or more frequencies in at least one ear (93.5% conductive loss). Applying a Canadian prevalence study definition, 148 (23.5%) children had hearing loss. Tympanic membrane perforations were present in 36.8% (n = 28) of children with unilateral and 45.8% (n = 22) with bilateral loss. CONCLUSIONS The prevalence of hearing loss in Canada's North was almost three times that reported for non-indigenous children. One in five school-aged children was found to have hearing loss that is likely to affect classroom learning and social/emotional development. A hearing health strategy tailored to this population is critically needed.

Abstract
Purpose This study investigated progressive hearing loss in a cohort of children who were identified with permanent mild bilateral hearing loss. Method This population-based study included 207 children with permanent mild bilateral hearing loss, diagnosed and followed from 2003 to 2016 in 1 region of Canada. Clinical characteristics and initial audiologic results were collected prospectively at diagnosis, and audiologic information was updated. Changes in hearing levels between the 1st and most recent assessment were analyzed to determine progressive hearing loss. Clinical characteristics were compared between children with progressive and stable hearing loss. The association between risk indicators and progressive hearing loss was explored through logistic regression. Results A total of 47.4% (94 of 207) had progressive hearing loss in at least 1 ear, and 50% (47 of 94) of those experienced more than 20-dB average drop in thresholds. For these 94 children, a total of 147 ears were affected, and 116 (78.9%) ears experienced sufficient change in thresholds to be coded as a worse category of hearing loss. In the subset of 85 children with more than 5 years of audiologic follow-up, 56.4% (53/85) showed a decrease in hearing. Of the total sample of 207 children, 137 (66.2%) continued to have mild hearing loss in the better ear. There was no association between the risk factors examined (family history of hearing loss, admission to the neonatal intensive care unit, or presence of a syndrome) and progressive hearing loss. Conclusion This study found that almost half of children with mild bilateral hearing loss showed a decrease in hearing in at least 1 ear. One third of the children first diagnosed with mild hearing loss in the better ear now have moderate or worse hearing loss in both ears. These findings point to the importance of careful long-term monitoring of children who present with mild hearing loss.
