[Giant osteomas of the paranasal sinuses].
At the Otorhinolaryngologic Department in Novi Sad we investigated osteomas of the paranasal cavities registered from 1960 to 1989. The total number of the treated patients was 30, aged from 31 to 60 years. A special attention is given to a female patient, aged 65 years with osteoma covering two thirds of the right nostril, both ethmoids and right retrobulbar space. It progressed upwards to the base of the skull causing denudation of the dura mater at the surface of 2.5 x 1.5 cm, and consecutive liquorrhea. The removed tumor weighed 110 grams and belonged to giant osteomas of the paranasal cavities.
