Cat cry syndrome (cri-du-chat syndrome) is an extremely rare condition characterized by a high shrill cry during infancy, resulting from either the deletion of the short arm of chromosome 5 or unbalanced translocation inherited from a parent. We report the case of a 1-year-old girl with cat cry syndrome associated with cleft lip. The patient showed a ventricular septal defect, cleft lip, growth and mental retardation, micrognathia, ptosis of the eyelids, hypertelorism, epicanthal folds, and a preauricular tag on the right side. A chromosomal study revealed the terminal deletion of chromosome 5 (46, XX, del(p14.2)ish del(5)). Repair of the cleft lip was carried out concurrently with resection of the preauricular tag, and the patient's postoperative course was uneventful.

BACKGROUND: Most cases of facial asymmetry involve yaw deformity, and determination of the yaw correction level is very difficult. METHODS: We use three-dimensional soft tissue simulation to determine the yaw correction level. This three-dimensional simulation is based on the addition of cephalometric prediction to gradual yaw correction. Optimal yaw correction is determined visually, and an intermediate splint is fabricated with computer-aided design and computer-aided manufacturing. Application of positioning devices and the performance of horseshoe osteotomy are advisable. RESULTS: With this procedure, accurate repositioning of jaws was confirmed and patients obtained fairly good facial contour. CONCLUSIONS: This procedure is a promising method for a widespread, predictable treatment of facial asymmetry.
