FRONTAL MUCOCELE AND DIPLOPIA - A CASE REPORT

The paranasal sinus mucocele is an epithelized cystic lesion containing fluid and is characterized by non-neoplastic expansion of the paranasal sinuses due to its capacity to erode the overlying bone. Etiology of these lesions is still under debate. In this report, we describe a case of frontal mucocele associated with proptosis and diplopia. A 56 year old male patient was admitted to our hospital in the department of Otorhinolaryngology with chief complaints of left sided nasal obstruction, double vision, swelling in the left eye and headache, all since 3 months. CT scan of the paranasal sinuses revealed a left sided dense hypoechoic mass with destruction of floor of the frontal sinus with intra orbital extension. All other laboratory examinations were within physiological limits. The patient was treated surgically by external approach. An incision was put in the left supra-orbital region and a bone window was created to access the frontal sinus and the mass identified and excised in-toto. Dermal fat graft was harvested the thigh and grafted into the recess. Histopathological examination of the mass revealed the mass to be a mucocele.
