Abstract:

Mucoceles are cystic lesions covered with normal respiratory mucosa that covers the paranasal sinuses. The obstruction of the sinus ostium due to tumor, surgery, trauma or chronic inflammation is responsible for the etiopathogenesis of mucoceles. Mucoceles are presented as an expansile and destructive lesion in clinical practice. Paranasal sinus mucoceles are most commonly seen in the frontal sinus, followed by anterior ethmoid and maxillary sinus. The paranasal sinuses are likely to develop ophthalmic complications in large mucoceles due to the close association with orbita. Surgical treatment of frontal sinus mucosal implies functional endoscopic sinus surgery, craniotomy with or without sinus obliteration, and craniofacial approaches. In this study, we aimed to discuss a case of frontal sinus mucopyocele who presented with preliminary diagnosis of orbital mass, swelling in the left eye and loss of seeing.
