Three-dimensional planning in craniomaxillofacial surgery.

Introduction: Three-dimensional (3D) planning in oral and maxillofacial surgery has become a standard in the planification of a variety of conditions such as dental implants and orthognathic surgery. By using custom-made cutting and positioning guides, the virtual surgery is exported to the operating room, increasing precision and improving results.

Materials And Methods: We present our experience in the treatment of craniofacial deformities with 3D planning.

Granulomatous enteritis and lymphadenitis in Iberian pigs naturally infected with Lawsonia intracellularis.

Intestinal samples and/or lymph nodes of two Iberian pigs from two different farms were submitted for histopathologic examination. Both pigs had proliferation of ileal and/or cecal crypts with almost complete absence of goblet cells. Infection by Lawsonia intracellularis was demonstrated by immunohistochemistry and polymerase chain reaction assay.

Giant cephalhematoma in a 15-year-old boy. Unilateral amaurosis as the main complication.

Background: The term "cephalhematoma" is applied to a collection of blood under the periosteum of a skull bone. It most frequently occurs in the neonatal period and is rare at other times of life.

Methods And Results: We report on a 15-year-old boy with a subperiosteal hematoma involving the whole cranial surface.
