We report a case of retained packing gauze in the right maxillary sinus following a Caldwell-Luc operation. Plain films showed total opacification of the right maxillary sinus. CT showed a mixed mesh-like soft tissue density and air in the centre of the lesion and a thick soft tissue band at the periphery of the right maxillary and ethmoid sinuses and nasal cavity.
