Three-Dimensional Computer-Assisted Two-Layer Elastic Models of the Face.

To make three-dimensional computer-assisted elastic models for the face, we decided on five requirements: (1) an elastic texture like skin and subcutaneous tissue; (2) the ability to take pen marking for incisions; (3) the ability to be cut with a surgical knife; (4) the ability to keep stitches in place for a long time; and (5) a layered structure. After testing many elastic solvents, we have made realistic three-dimensional computer-assisted two-layer elastic models of the face and cleft lip from the computed tomographic and magnetic resonance imaging stereolithographic data. The surface layer is made of polyurethane and the inner layer is silicone.

Ultrasonographic Images of Nasal Bone Fractures with Water Used as the Coupling Medium.

Background: Ultrasonography can show local and superficial fractures of the nasal bone. However, it is difficult to see the whole nasal bone. We used water as the coupling medium for ultrasonography.

Malar Reconstruction Using Y-V Advancement Flaps after Tissue Expansion in Treacher Collins Syndrome.

The Treacher Collins syndrome is characterized by both soft and hard tissue deficiencies. To reconstruct malar hypoplasia with both soft and hard tissues, we designed a new method using cartilage grafts, Y-V advancement flaps, and Z plasty with tissue expansion.

A case of optic-nerve hypoplasia and anterior segment abnormality associated with facial cleft.

Introduction: The incidence of facial cleft is rare and ranges between 1.43 and 4.85 per 100,000 births.

A Case of Complex Facial Clefts Treated with Staged-tissue Expansion.

Craniofacial clefts involve all soft tissue and skeletal elements throughout the cleft. Usefulness of tissue expansion in craniofacial clefts is reported. Surgery for a complex type of facial clefts is more difficult and more extensive than for a simple one.
