The U-Shaped Maxillary Osteotomy: A Novel Resource for the Treatment of the Middle Third Facial Hypoplasia.

The purpose of orthognathic surgery procedures is to manipulate the elements of the facial skeleton to reestablish normal anatomy and function. These elements could be repositioned with the technique known as Le Fort I osteotomy. This technique can be modified to be adapted on each patient, depending on the anomaly presented and the planned objective.

Large cell calcifying Sertoli cell tumor: a clinicopathologic study of 1 malignant and 3 benign tumors using histomorphology, immunohistochemistry, ultrastructure, comparative genomic hybridization, and polymerase chain reaction analysis of the PRKAR1A gene.

Four cases of large cell calcifying Sertoli cell tumor, 3 benign and 1 malignant, with no clinical signs of Carney complex or Peutz-Jeghers syndrome are reported with results of histologic, immunohistochemical, ultrastructural, and comparative genomic hybridization studies. Analysis of PRKAR1A gene was performed on 2 cases. The age range of the patients was 19 to 54 years.

Multivectorial, external halo-assisted midface distraction in patients with severe hypoplasia.

Osteogenesis distraction is an increasingly used technique for the correction of facial deformities because it offers a faster and more controlled growth of the hypoplasic bone along with the elongation of the soft tissues. In this article, we describe the technique and our experience in midface distraction using an external multivectoral distraction device (BLUE Device; W. Lorenz, Jacksonville, FL) and custom-made midface osteotomies for the correction of severe hypoplasia.

Germ cell tumors with sarcomatous components: a clinicopathologic and immunohistochemical study of 46 cases.

The clinicopathologic features of 46 patients with germ cell tumors with sarcomatous components (GCTSC) involving either the primary site or their metastases were studied. There were 43 men and 3 women aged 17 to 74 years. Twenty-three tumors arose in the mediastinum, 2 in the retroperitoneum, and 21 in the gonads.

EGF-R and erbB-2 in murine tooth development after ethanol exposure.

Background: Alcohol consumption during pregnancy can frequently lead to a congenital disorder known as fetal alcohol syndrome (FAS); however, not all children born to alcoholic women develop FAS. Alcohol consumption may affect diverse organs and systems during embryonic development, including craniofacial structures. Small teeth, enamel alterations, and delayed eruption have been observed after ethanol exposure.
