ORBITAL EXTENSION OF A LARGE FRONTAL SINUS OSTEOMA ASSOCIATED WITH FIBROUS DYSPLASIA

Giant frontal osteoma: case report with review of literature

Diagnosis of frontal osteoma is usually by chance, but rarely these can produce exceptional ophthalmologic and neurological complications apart from cosmetic disfigurement. Etiology of frontal osteoma may be multifactorial. Surgical management should be site and size specific. A combination of open surgery and endoscopic methods would help confirm complete removal of the tumor. Here we report a fronto-ethmoidal osteoma of size 7.1 × 5.3 × 5.1 cm which is one of the largest reported in literature. Also, we have done an extensive web search and text based review of the literature on frontal osteoma in terms of its incidence, etiology, pathology, clinical presentation, complications and important developments in management. The available literature and our own experience suggest that even large osteoma arising in the fronto-ethmoid region can be completely removed surgically with minimum complications. The surgical approach can be varied according to the extent of the tumor and patient considerations. A regular follow up is necessary in asymptomatic cases being treated conservatively, in view of the potential complications.
