[Orbital osteoma: clinical evaluation of nine cases].
Rev Stomatol Chir Maxillofac. 2005 Feb; 106(1):7-12.RS

Abstract

INTRODUCTION

Osteoma of the nasosinus cavities, particularly the frontoethmoidal cavities, is often a fortuitous radiographic discovery. Potential complications include ophthalmological, sinusal, and endocranial disorders.

MATERIAL AND METHODS

Nine patients (five men and four women), mean age 24.3 years (18-43) presenting orbital osteoma were managed from 1994 to 1999.

RESULTS

Clinical signs were dominated by ophthalmological disorders, basically non-reducible exophthalmia (n = 8). Two patients had permanent unilateral nasal obstruction and one had acute sinusitis. The bony orbital tumefaction was located in the superior medial angle in five patients. Radiography (Blondeau view) demonstrated an opacity in the sinus with an orbital extension. Computed tomography, performed in all patients, identified the lesion location: ethmoidofrontal (n = 4), anterior ethmoidal (n = 2), frontal (n = 2), ethmoidomaxillary (n = 1). There were no endocranial extensions. Surgery was undertaken for eight patients generally via the transfacial approach (n = 7); a bicoronal approach was used for one patient. En bloc resection (n = 4) or fragmentation (n = 4) was performed. There was one postoperative complication: regressive diplopy. These patients have been followed regularly with clinical and radiographic explorations and have been free of relapse for 2 to 6 years.

DISCUSSION

Frontoethmoidal osteoma is a relatively rare benign tumor. Severity depends on the orbital and endocranial extension. Imaging provides the positive diagnosis and guides the surgical approach. Therapeutic indications depend on the tumor size, its course, and the development of complications. We observed total relapse free outcome after complete resection.
