Introduction: Lesion-forming bone tissue, benign, composed of mature and well-differentiated bone tissue, with a predominantly laminar structure and slow growth presents radiographic appearance of homogeneous densification. Osteomas develop almost exclusively in the skull and jaw and sometimes invade the sinuses in the form of dense bone mass. It should be clinically monitored, without surgery or other treatment. The prognosis is good.

It improved with painkillers. It evolved with worsening in the past 6 months, emerging crises refractory to common analgesic, motivating trips to the emergency room (ER) in at least six opportunities.

He underwent excision of osteoma in the operating room for open and transnasal route. In histopathological analysis, diagnosis of osteoma was confirmed. Patient had an uneventful postprocedure.
