Osteoma of Nasal Bone and Temporal Bone : A Case Series

Abstract

Osteoma is a benign tumour of the bones. The bony growth can be formed anywhere in the body over an already normal bony surface or over some other tissue in the body known as homoplastic and heteroblastic Osteomas respectively. The factors that lead to the formation of Osteomas are not fully understood but altered cycles of bone resorption and formation have been hypothesized in their occurrence. On the basis of types of bone they are classied into Combined, Spongy and Mixed types. The osteomas generally do not present with any peculiar symptoms but are an incidental nding in many patients, Symptoms generally depend on the location and mass effect over nearby structures present. Most Osteomas occur in the Paranasal Sinuses and in the Skull. Management of Osteomas is generally surgical in case they are symptomatic due to mass effect. Both Endoscopic and open approaches are considered for their removal. We are presenting a case series of two, each case harbouring Osteoma at an uncommon site.
