Objectives: To determine the prevalence of incidental mastoid opacification (OIM) in a pediatric population from one hospital. Verify the events that led to otolaryngology consultation and to ascertain occurrence of ear disease.
Study design: Retrospective study
Material & methods: We analysed the computed tomography scans (head, paranasal sinus, temporal bone) performed across 2 years in individuals <18-year-old. CT scans with an otologic or traumatic indication were excluded. The degree of mastoid opacification was evaluated in all 650 exams.
Results and Conclusions: OIM was found in 10,9% of cases (71/650). This rate was significantly higher in children ≤8-yearold (22,9%; 42/183); p=0,03. OIM was strongly associated to adenoid hypertrophy in children ≤8-year-old (eta=0,879). We observed that 29,6% of OIM cases (21/71) were referred to otolaryngology consultation and none of these children had ear disease needing treatment. OIM is rarely pathologic and shouldn’t be overemphasized.
