Orbital lipogranuloma after sinus surgery.

PURPOSE

To report the treatment and histopathological findings in two cases who developed eyelid swelling, proptosis and diplopia due to orbital and lid lipogranuloma after endoscopic surgery of the maxillary and ethmoidal sinuses.

METHODS

To relieve the proptosis and diplopia, debulking surgery was done on the eyelids and orbit. The tissue removed was sent for histopathological examination.

RESULTS

The two patients improved after surgery. The eyelid swelling, proptosis and diplopia subsided and ocular movements became normal. Histopathologic examination disclosed an extensive lipogranuloma.

CONCLUSIONS

Extensive orbital and eyelid lipogranuloma causing proptosis and diplopia is a rare complication of endoscopic sinus surgery, and can be relieved by surgical debulking.
