Abstract:
The authors report a case of asymmetric development of the mastoid antrum in a neonate. The lack of mastoid development most likely represents a congenital maldevelopment. Agenesis of the mastoid antrum has surgical implications, as failure to recognize its absence can result in disorientation during surgery, with potential to injure adjacent structures.
