“…Regarding the otoacoustic emissions, the smokers group showed a lower response level in the frequencies of 1 kHz in both ears and 4 kHz in the left ear [19]. Comparisons between exposed newborns to control group revealed statistically significant decreases of TEOAEs amplitudes at 4 kHz [10]. …”

The rate of smoking in Brazil is about 18.8%. Exposure to environmental tobacco smoke is one of the major factors predisposing children to several hazardous health problems. The objective of the present research was to analyze the effect of tobacco smoke exposure during childhood on cochlear physiology by measuring the transient evoked otoacoustic emissions (TEOAE) response levels. Cotinine, the main metabolite of nicotine, was measured in 145 students’ (8–10 years old) urine. Sixty students indicated tobacco smoke exposure (TSE) (cotinine urine levels ≥ 5.0 ng/mL) and 85 did not. The evaluation of TEOAE of TSE students showed lower response levels, mainly on frequencies of 2.8 kHz on the right and left ears and 2.0 kHz on left ear and lower signal noise response levels, mainly on the 1.0 kHz and 1.4 kHz frequencies, when compared to controls that were not exposed to tobacco. The mean hearing loss in tobacco smoke exposure children was 2.1 dB SPL. These results have important implications on the damage to the cochlear structures and indicate a possible loss in hearing and hearing ability development.

“…This new approach to study the cochlea improves the ways to investigate and interpret hearing loss. Recent findings suggest that the auditory functions in infants of smoking mothers were significantly reduced as measured by OAE [9,10] and auditory brainstem response [11,12,13]. …”

“…9,30–32 Thus, reduction without cessation appears insufficient to eliminate tobacco-associated risk both during pregnancy and afterward. Pregnant women may be advised that tobacco exposure as minimal as 1 to 4 cigarettes per day is sufficient to increase the risk of bearing a child affected by hearing loss.…”

“…The second study (n = 200 neonates) also demonstrated a lower TEOAE mean response overall and at 4000 Hz specifically ( P = .001). 32 This difference was observed in even the lowest exposure group of less than 5 cigarettes daily ( P = .01) and persisted as the intermediate and higher dose groups were compared to the nonsmoking group ( P = .01, .04). Again, increasing the dose of tobacco exposure did not further increase the impact on hearing among those who were exposed.…”

Background Pediatric hearing loss is an increasingly recognized problem with significant implications. Increasing our quantitative understanding of potentially modifiable environmental risk factors for hearing loss may form the foundation for prevention and screening programs. Objective To determine whether specific threshold exposure levels of personally modifiable risk factors for hearing loss have been defined, with the overarching goal of providing actionable guidance for the prevention of pediatric hearing loss. Data Sources A systematic review was performed. Computerized searches of PubMed, EMBASE, and the Cochrane Library were completed and supplemented with manual searches. Review Methods Inclusion/exclusion criteria were designed to determine specific threshold values of personally modifiable risk factors on hearing loss in the pediatric population. Searches and data extraction were performed by independent reviewers. Results There were 38 criterion-meeting studies, including a total of 50,651 subjects. Threshold noise exposures significantly associated with hearing loss in youth included: (1) more than 4 hours per week or more than 5 years of personal headphone usage, (2) more than 4 visits per month to a discotheque, and (3) working on a mechanized farm. Quantified tobacco levels of concern included any level of in utero smoke exposure as well as secondhand exposure sufficient to elevate serum cotinine. Conclusions Specific thresholds analyses are limited. Future studies would ideally focus on stratifying risk according to clearly defined levels of exposure, in order to provide actionable guidance for children and families.
