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.

The identification code of a drug is defined as “a code for identifying tablets, etc.” and is described in the “Composition/Properties” section of the package insert. We investigated whether the Pharmaceuticals and Medical Devices Agency (PMDA) website, which allows users to search package insert information, can be used for drug identification using identification codes in 2019 before the new package insert guidelines were implemented, and in 2022, during the revision period. Approximately 30% of the investigated high-risk drugs were unidentifiable in both years. The most common reason was that images were used to register identification codes on the PMDA website, and character strings were not searchable. We then conducted a questionnaire survey of pharmaceutical companies, and only approximately half of the respondents opined that it would be preferable if the registration format for identification codes was established within the pharmaceutical industry. However, hospital pharmacists urged for more simplified identification of drugs on the PMDA website.
