[Reconstruction of the frontal bone after trauma (author's transl)].

Reconstruction of the frontal bone after trauma has to be performed in a different manner according to whether the frontofacial lesions are associated or not with neurosurgical disturbances. The lesions in the first case mainly affect all the orbital borders and the anterior walls of the frontal sinuses. Reconstruction of the frontal bone usually requires osteosynthesis to the metallic threads of the various fragments applied, but the treatment of the frontal sinus region must be modulated in relation to the possible existence of posterior wall lesions. Frontofacial lesions associated with neurosurgical disorders require the combined efforts of a neurosurgical and maxillofacial team at the same time. The frontal sinus extends into the cranial region in all cases. Frontal bone reconstruction requires the use of various techniques (osteosynthesis to metallic threads, grafts taken from the iliac or other bones), according to the site and severity of the traumatic lesion.
