What should you know about frontal bone osteomyelitis?

The frontal bone forms the front of the skull and lies close to the forehead skin, the tissues around the eyes, and the frontal sinuses. Infection may enter through nearby sinus disease, a wound, surgery, or spread through the bloodstream. Possible features include persistent forehead pain or swelling, tenderness, fever, headache, drainage, or feeling generally unwell. Symptoms can overlap with sinus or skin problems, so examination alone may not show how deep the infection is.

A clinician may assess the skin and scalp, eyes, nose, neurological function, and general health. Imaging can show changes in bone and nearby spaces, while blood tests or a sample may help guide antimicrobial treatment. The condition is not something to manage with massage or leftover medication.

Arrange prompt medical review, especially when forehead swelling, worsening pain, fever, or discharge is present. Take prescribed medicines exactly as directed and complete the planned course unless the treating team changes it. Keep any wound clean according to instructions, and tell the clinician about recent sinus symptoms, dental problems, injuries, procedures, or immune-system conditions.

Treatment may involve antimicrobial medicine and, when infected or damaged tissue cannot settle, a procedure to drain or remove it. Follow-up matters because bone infection can require repeated examination and imaging. If reconstruction is discussed after tissue removal, ask how [Bone Grafting](/treatments/trauma-and-fracture-care/bone-grafting/) fits into the plan.

Seek emergency care for confusion, unusual sleepiness, a seizure, weakness, new vision changes, severe headache, repeated vomiting, swelling around an eye, or rapidly worsening forehead swelling. These signs can indicate spread beyond the local bone and need immediate assessment. Fever with a severe or escalating headache also warrants urgent review rather than waiting for a routine appointment.

Ask which area is infected, what imaging is needed, whether a culture can guide treatment, how long treatment is expected to continue, and which symptoms should trigger emergency review. You can also ask whether an ear, nose and throat specialist, infectious-disease clinician, neurosurgeon, or reconstructive surgeon should be involved.
