SUMMARY
 

The paranasal sinus mucocele is an epithelized cystic lesion containing fluid and is characterized by non-neoplastic expansion of the paranasal sinus due to its capacity to erode the overlying bone. Etiology of these lesions is still under debate. In this report, we described a case of a patient with frontal recess mucocele, associated with contralateral frontal recess osteoma. A 55-year-old man was admitted to the Department of Otorhinolaryngology of our hospital with the complaints of a headache affecting the frontoethmoidal region, left-sided nasal obstruction, and postnasal discharge. Computed tomography (CT) scan of the paranasal sinuses showed a dense bony lesion in the left and a cystic hypodense mass in the right-sided frontal recess. The patient was treated surgically, with a combined endoscopic-external approach, bilaterally. Histopathological examination showed that the wall of the cyst was mucocele, and the bony formation was osteoma. The frontal recess osteoma is regarded as the primary condition. Thus, better ventilation and drainage of the frontal sinus were reestablished.

Key words: mucocele osteoma, frontal recess, endoscopic sinus surgery, external approach surgery
