[Immediate reconstruction of the fractured anterior wall of the frontal sinus (author's transl)].

Report on 83 cases of frontal sinus wall fractures. All cases including those with cerebrospinal liquorrhea, early meningitis and brain tissue prolaps were operated on as early as possible, and the anterior wall of the frontal sinus reconstructed immediately by means of multiple wire osteosyntheses. The follow up shows that even very small bone fragments are built in again, and no resorption ensues. X-rays and bone-scintigramms show that these membranously preformed bone fragments reunite well and consequently underly other healing conditions than chondrally ossified bones. Until now, no endocranial complications at all have appeared. The procedure although primarily timeconsuming, has proven to be superior to the Riedel obliteration method with following plastic restoration of the profile as regards the cosmetic results and the length of treatment.
