Air-fluid level in left maxillary sinus. Bilateral mucosal thickening in maxillary sinuses and most ethmoidal air cells. Mastoid air cells undeveloped on right and underdeveloped on left.
Opacified right middle ear and antrum. Adjacent minimal right temporal pneumocephalus, apparently due to dehiscence of the tegmen tympani, plus one right frontal parafalcine bubble.
