Total aplasia
of the paranasal sinuses and nasal cavity: the first case report. a–c The sagittal sections of the facial CT scan demonstrate a non-pneumatized, compact maxilla; an aplastic sphenoid bone; aplastic frontal sinuses; and a high-riding, convex palatal arch, resulting in increased space in the oral cavity in the craniocaudal dimension (green triangle). The scan also shows a normal pituitary fossa (blue circle) and the absence of a nasal cavity
