Abstract

Osteomas are benign mesenchymal osteoblastic tumors of lamellar bones. In our practice, they are usually seen in the paranasal sinuses, mainly involving the frontal and ethmoidal sinus. Osteoma of the temporal bone is uncommon and when they occur, they are most commonly seen in the external auditory canal. Mastoid osteomas are a rare entity with incidence of 0.1 - 1% of all benign tumors of skull. They are slowing growing and usually asymptomatic. We report a rare case in a 28 years female patient who presented to us with right postauricular bony swelling of size 2.5×3 cms along with bilateral nasal obstruction. Patient was analyzed for her clinical condition, imaging details, treatment and surgical plan. Diagnosis of right mastoid osteoma with right nasochoanal polyposis was made after non-contrast computed tomography of temporal bone and paranasal sinuses respectively. Complete surgical excision of the osteoma along with endoscopic removal of the polypoidal tissue was done with good cosmetic outcome without recurrence.
