Abstract: We report a case of cement-ossifying giant fibroma of rare topography which occupied the right parapharyngeal space from the angle of the mandible to the middle cranial fossa. Its; origin in the pterygoid apophysis of the sphenoid bone is demonstrated and discussed. Even though the fibroma occupied this region, its surgical removal was possible through a combined craniocervical approach without producing sequelae for the patient. The authors describe the diagnostic methods employed and the surgical technique adapted and discuss the terminology related tho these tumors.
