Abstract

Carcinoma of the paranasal sinuses is a very serious disease, but its incidence is lower than that of any other oral malignancy. Failure to diagnose it early because of misleading symptoms resembling sinusitis usually leads to its detection at a stage when it has already destroyed the bony walls of the sinus and has spread to surrounding structures (infratemporal fossa, posterior ethmoid cells, orbit, cribriform plate, nasopharynx, sphenoid sinus or base of the skull). It is uncommon for this cancer to spread to the regional lymph nodes as long as it remains confined within the maxillary sinus. CT scanning provides an accurate assessment of the extent of resection required and is usually used as an indicator of operability.

A 56-year-old man with a chief complaint of palatal swelling, pain and pus discharge was referred to Seoul National University Dental Hospital. Orthopantomogram and Waters' view revealed an aggressive bone destruction in the right maxillary molar area, ipsilateral sinus opacification and destruction of the lateral wall of the maxillary sinus. The CT fidding showed that the right maxillary sinus was occupied by a soft tissue mass which represented a central low density, with an irregular shape at some levels. The tumor mass also involved the pterygopalatine fossa, right esthmoid sinus, nasal cavity and hard palate. Incisional biopsy was done and the biopsy report was squamous cell carcinoma. He was transferred to Internal Medicine for chemotheraphy because of inoperability.
