Osteoma of Temporal Bone: Case Series

Abstract

Osteomas are rare mesenchymal tumours which can be canalicular or extracanalicular.In our case series we are presenting both the type of osteomas of temporal bone to highlight the difference in presentation and management. EAC is the most common site of osteoma and squamous part of temporal bone involvement is rarely encountered. Clinical presentation of osteomas may range from painless bony mass in extracanalicular involvement to one causing tinnitus and ear discharge if present in the external auditory canal.The differential diagnosis include  paget’s disease, osteosarcoma, keratosis obturans. A high resolution computed tomography of the temporal bone is the investigation of choice.The diagnosis can only be confirmed by histopathology whereby we see mature lamellar  and woven bone with harvesian  canal.
