Definition and Types of Osteoma
- Osteoma is a new piece of bone growing on another piece of bone, usually the skull.
- It is a benign tumor.
- When the tumor grows on other bone, it is known as homoplastic osteoma.
- When it grows on other tissue, it is called heteroplastic osteoma.
- Osteoma is the most common benign neoplasm of the nose and paranasal sinuses.
Causes and Theories
- The cause of osteomas is uncertain.
- Commonly accepted theories propose embryologic, traumatic, or infectious causes.
- Osteomas are also found in Gardner's syndrome.
- Larger craniofacial osteomas may cause facial pain, headache, and infection.
- Obstructed nasofrontal ducts can lead to infection in craniofacial osteomas.
Symptoms and Presentation
- Craniofacial osteoma often presents itself through ocular signs and symptoms, such as proptosis.
- Facial pain and headache can be symptoms of larger craniofacial osteomas.
- Infection can occur due to obstructed nasofrontal ducts.
- Osteomas in the nose and paranasal sinuses can cause facial pain and infection.
- Osteomas can lead to obstruction of nasofrontal ducts.
Medical Management
- Management of a large frontoethmoid osteoma may involve sinus cranialization and cranial bone graft reconstruction.
- Medical management may be required for symptomatic osteomas.
- Surgical intervention is often necessary for craniofacial osteomas.
- Osteomas can be managed with appropriate medical and surgical interventions.
- Treatment options for osteomas include surgical removal and reconstruction.
Additional Resources
- External links on eMedicine provide information about osteoid osteoma.
- eMedicine also provides information about osteoma cutis.
- Pathology images of osteoma can be found on Humapth #4724.
- Osteoma is classified under ICD-10 as D16.
- ICD-9-CM classification for osteoma is 213.0.
An osteoma (plural osteomas or less commonly osteomata) is a new piece of bone usually growing on another piece of bone, typically the skull. It is a benign tumor.

When the bone tumor grows on other bone it is known as "homoplastic osteoma"; when it grows on other tissue it is called "heteroplastic osteoma".
Osteoma represents the most common benign neoplasm of the nose and paranasal sinuses. The cause of osteomas is uncertain, but commonly accepted theories propose embryologic, traumatic, or infectious causes. Osteomas are also found in Gardner's syndrome. Larger craniofacial osteomas may cause facial pain, headache, and infection due to obstructed nasofrontal ducts. Often, craniofacial osteoma presents itself through ocular signs and symptoms (such as proptosis).
