Small defects may occur after resorbtion of bone fragments or bone grafts in comminuted anterior table fractures. To prevent such defects, titanium mesh may be helpful in the primary fracture treatment.
Chronic infections related to sinus disease may also cause bone loss in the anterior table.
Extensive defects are usually related to high energy open fractures (eg. gunshot wounds) or neurosurgical procedures (eg. decompressive craniectomy).
