Osteoma of the ethmoidal sinus: a rare case of recurrence

Abstract

Osteomas are slow growing bony tumours that may form in the sinuses of the skull. Presenting complaints include headaches, cerebral symptoms, or visual disturbances, depending on the site of the tumour. We describe an unusual case of an osteoma in the ethmoid sinus that recurred 5 years after its resection at another hospital. The patient presented with proptosis, epiphora, and headaches. We approached the lesion and removed it through a lateral nasal incision. Two years later the patient was free of symptoms.
