Mucoceles are benign locally expansive masses of the paranasal sinuses.They most commonly affect the frontal and ethmoid sinuses.Aggressive mucoceles may erode the surrounding walls of the sinus and they must be differentiated from the carcinomas.Giant maxillary antral mucoceles causing bone destruction are Heater Assy extremely rare in patients who have no previous history of nasal or sinus surgery.Computed tomography is the most important tool for the diagnosis of the disease.
The treatment of maxillary antral mucoceles is surgical.The traditional method is external approach, with complete excision of the cyst wall.Endoscopic treatment is usually chains reserved for mucoceles that do not extend beyond the limits of the maxillary sinus.We report a case with a giant maxillary antral mucocele that caused facial asymmetry in a patient with no history of previous nasal or sinus surgery.The imaging methods and surgical treatment options of the disease is presented and the literature is reviewed.
