Radiographic SSCD, although uncommon, appears to be more prevalent in younger children, especially infants younger than 12 months. This suggests that the SSC may develop more bony covering with age.

Considerable variation exists in pediatric temporal bones. The largest difference in the transmastoid angle was seen in children aged 1 to 4 years. The largest variability in the transcanal angle is between the infant (<12 months) and children >4 years of age. These differences are surgically relevant for round window identification and facial nerve safety during cochlear implant surgery in infants.

thresholds in 500 Hz, 2000Hz, and tritonal mean (P = 0.003, P = 0.03, and P = 0.02, respectively) Conclusions: The posterior mesotympanic cholesteatomas had greater air-bone gap thresholds in the speech frequencies when compared with posterior epitympanic cholesteatomas. However, the two growth patterns were very similar in the other audiometric parameters.
