Any type of sensory deprivation in childhood resulting from conductive hearing loss may impair the development of peripheral and central auditory pathway structures with negative consequences for binaural processing. To characterize and compare monoaural and binaural auditory responses in neonates and children without and with a history of recurrent otitis. The study included participants from 0 to 8 years and 11 months old, in good general health conditions, of both genders, divided into a control group, with no history of otitis, and a study group, with history of recurrent otitis. Cortical potential with speech stimulus /ba/-/da/ was used as collection procedure. The arithmetic calculation of the 512 points of the wave was performed to obtain the grand average of the waves of the subjects in both groups. The Shapiro-Wilk and mixed repeated measures analysis of covariance (ANCOVA) statistical tests were performed to analyze the group effect, the condition, and the interaction (group versus condition) controlling the effect of the age-sex covariable. There was a statistically significant difference between the groups for all latency values; and for the P1, N1, P2, and N2 latencies, the differences between the groups occurred in the three analyzed conditions (right and left ears and binaural), revealing the influence of sensory deprivation. There were no significant differences in relation to wave amplitudes. There are differences in the cortical potential with speech stimuli and in the binaural interaction component of children with and without history of recurrent otitis.
童年期因传导性听力损失导致的任何类型的感觉剥夺都可能损害外周和中枢听觉通路结构的发育，对双耳处理产生负面影响。
为了表征和比较有无复发性中耳炎病史的新生儿和儿童的单耳和双耳听觉反应。
该研究纳入了年龄在0至8岁11个月、一般健康状况良好、男女皆有的参与者，分为无中耳炎病史的对照组和有复发性中耳炎病史的研究组。使用语音刺激/ba/-/da/的皮质电位作为采集程序。对波的512个点进行算术计算，以获得两组受试者波的总体平均值。进行了Shapiro-Wilk检验和协方差混合重复测量分析（ANCOVA）统计检验，以分析控制年龄-性别协变量效应的组效应、条件以及交互作用（组与条件）。
所有潜伏期值在两组之间均存在统计学显著差异；对于P1、N1、P2和N2潜伏期，两组之间的差异出现在三种分析条件下（右耳、左耳和双耳），揭示了感觉剥夺的影响。波幅方面无显著差异。
有或无复发性中耳炎病史的儿童在语音刺激的皮质电位和双耳交互成分方面存在差异。
