Dense osteoma of the frontal bone is a small, hard, benign tumor that develops on the frontal bone, usually without any conscious symptoms. Dense frontal bone osteoma is a type of cranial osteoma, which is a slow-growing benign tumor that usually stops growing when the bones of the body mature. Cranial osteoma can occur in any part of the skull, mostly in the frontal bone and parietal bone, and mostly in young and middle-aged people. If the size of dense osteoma of the frontal bone is small, there is usually no conscious symptom, but if the size is large, there will be localized swelling and pain or numbness. When discomfort such as head swelling and pain occurs, one should consult a doctor in time, under the guidance of a professional doctor for examination, clear diagnosis, and choose the appropriate treatment.
