Abstract

Objective: The adult petromastoid canal (PMC) is a thin anatomical structure, but in young children, it can be wide on high resolution CT (HRCT) scans. We performed this study to evaluate the year-by-year change in width and shape of the PMC in the young child.

Materials and methods: We retrospectively reviewed temporal bone HRCT scans, performed between 2007 and 2012. Eighty children were included (age range: 0.3-6.9 years; median age: 3.1 years; 56% male). All scans had a slice thickness of

Results: The average width of the PMC was 1.95 mm in children = 2 (p <0.001). We categorized the PMC into 4 subtypes. A bulky (type III) PMC was predominant

Conclusion: A wide PMC (>= 1 mm) is a common finding in children
