Rehabilitation after Excision of Osteoma on the Supraorbital Border: A Rare Case Report

Abstract

Osteoma is a benign, exophytic neoplasm composed of osteoids and bone tissue of uncertain origin. It can occur in any bone, but is more common in the bones of face and paranasal sinuses. Its involvement with the orbital cavity is rare. When this occurs, the lesion usually arises from the paranasal sinuses with extension to the orbit. This paper presents the case of a patient with a supraorbital border osteoma without the involvement of any sinus of the face. A 34-year-old patient sought care due to a volumetric increase and aesthetic defect in the supraorbital region. Information from anamnesis, clinical examination and imaging tests led to the diagnostic hypothesis of osteoma. Surgical excision of the lesion and reconstruction of the defect on the right supraorbital border with titanium mesh was performed. Histological analysis confirmed the initial hypothesis. Although rare, the primary involvement of the osteoma with the orbital cavity was evidenced. Reconstruction of the bone defect caused by the excision of the lesion with titanium mesh proved to be a satisfactory therapeutic option to restore the anatomical contour of the patient.
