RESUMO
Eighty-two-day-old male Wistar rats were selected to study the pattern of craniofacial growth following resection of the zygomatic arches. Rats were divided into three groups: group I (n = 14), the control group; group II (n = 15), with unilateral resection of the zygomatic arch; and group III (n = 8), with bilateral resection. Direct dry skull and cephalometric measurements show increased facial projection and decreased transverse facial width on the side of the resected arch. If the results are extrapolated to the growth pattern of patients with the Treacher Collins syndrome, we can conclude that the zygomatic arch acts as a "moderator" in the morphologic development of the face.

Treacher Collins syndrome is a complex congenital malformation. The most important manifestations of this syndrome are hypoplastic or absent malar bone, centrofacial over-projection, eyelid coloboma, and micrognathia. This article presents an approach to re-establish the right centrofacial proportions through "flattening osteotomies" of the maxilla, malar bone reconstruction, and other maxillo-mandibular osteotomies.

A case of hepatic rupture in 32 years old woman with severe preeclampsia is presented. She was definitively treated by right hepatic arterial occlusion and right porta branch occlusion. There were no postoperative complications, and the patient is still alive. This is the first case report of right hepatic arterial occlusion and right porta branch in severe preeclampsia.
