Six were bilateral. Thirty\u2010one patients (5.2%) were found to have hypoattenuation of the otic capsule. There were no coincident cases of IAC diverticulum and hypoattenuation of the otic capsule. There was no association between the presence of IAC diverticula and age (<jats:italic>P<\/jats:italic> = .13). In six patients with unilateral diverticula, pure tone average (<jats:italic>P<\/jats:italic> = .42), and word recognition (<jats:italic>P<\/jats:italic> = .27) scores were not significantly different when compared to the normal, contralateral side.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The prevalence of IAC diverticula in children is lower than the prevalence in adults.
