[Spatial distribution of facial volumes. Ontogenetic and phylogenetic study with vestibular orientation].

On cephalic skeleton of Man and two species of chimpanzees, statistically considered during their growing, a sagittal area is measured in facial mass and total face. Barycenters are determined. This points describe, in vestibular axis, ontogenic curves with posterior concavity more important in Man. Remarkable relations exist between barycenters and several facial and mandibular points, and with those of frontal and parietal vault.

Development of a protocol for coronal reconstruction of the maxillofacial region from axial helical CT data.

Using a fresh frozen cadaver head, a series of axial helical CT scans were obtained using varying imaging parameters both before and after traumatizing the head. The appearance of reformatted coronal images was optimized for the lowest radiation dose. A protocol for imaging the maxillofacial region was developed that produced diagnostic coronal reconstructed images from the axial helical CT data.

Early bone grafting in complete cleft lip and palate cases following maxillofacial orthopedics. II. The soft tissue development from seven to thirteen years of age.

The subsequent effect of preoperative maxillofacial orthopedics and early bone grafting on the development of the soft tissue profile of the face was studied with roentgencephalometric analysis on cleft patients between 7 and 13 years of age. They were divided into two unilateral and one bilateral complete-cleft group, all having been bone grafted early with the "four-flap" technique. The two unilateral groups were one group of 39 children operated on between 1960 and 1965 without preoperative orthopedics and one group of 46 children operated on between 1965 and 1972 after preoperative orthopedics ("T-traction"). The bilateral group comprised 19 children operated on between 1960 and 1972 after premaxillary retropositioning pressure, combined when necessary, with outward rotation of the lateral maxillary segments. Comparisons of facial growth were made with U.S. non-grafted clefts and with nonclefts. The effect of the preoperative orthopedic management facilitated the subsequent surgical procedure by a narrowing of the cleft and replacement of the deviated maxillary and nasal structures. The results were within limits of the non-grafted cases, with the exception of the soft tissue overlying the subnasal region. The reduced prominence of that region was explained by the primary surgical procedure, which made the lip adherent to the alveolar crest. In comparison with nonclefts, all parameters indicated a reduced growth capacity.
