Perioperative Hypertension Management during Facelift under Local Anesthesia with Intravenous Hypnotics.

Perioperative hypertension is a phenomenon in which a surgical patient's blood pressure temporarily increases throughout the preoperative and postoperative periods and remains high until the patient's condition stabilizes. This phenomenon requires immediate treatment not only because it is observed in a majority of patients who are not diagnosed with high blood pressure, but also because occurs in patients with underlying essential hypertension who show a sharp increase in their blood pressure. The most common complication following facelift surgery is hematoma, and the most critical risk factor that causes hematoma is elevated systolic blood pressure.

Serum cancer biomarker discovery through analysis of gene expression data sets across multiple tumor and normal tissues.

The development of convenient serum bioassays for cancer screening, diagnosis, prognosis, and monitoring of treatment is one of top priorities in cancer research community. Although numerous biomarker candidates have been generated by applying high-throughput technologies such as transcriptomics, proteomics, and metabolomics, few of them have been successfully validated in the clinic. Better strategies to mine omics data for successful biomarker discovery are needed.

Sagittal split ramus osteotomy with mandible reduction.

Background: The sagittal split ramus osteotomy is a well-established procedure, and many authors have attempted various modifications of the surgical technique. Nowadays, it is widely acknowledged that people in Korea, Japan, and China prefer an oval face, the lower part of which is slender. Therefore, among facial contouring procedures, the mandible reduction procedure is the most popular procedure in these countries.

Three-dimensional mandible reduction: correction of occlusal class I in skeletal class III cases.

Background: The human face is a three-dimensional structure. However, many studies on mandible reduction procedures are based on a two-dimensional concept, with a particular focus on one dimension: the width of the lower face. Many Korean individuals have class I occlusion with a skeletal class III pattern.

Misconceptions about mandible reduction procedures.

Mandible reduction procedures are currently very popular in Asian countries. But many misconceptions or differences in concepts about these procedures still exist, mainly because of preconceived ideas and restriction in communication. The author reviewed articles and found some misconceptions about these procedures.

Mandibular angle reduction versus mandible reduction.

The terms "mandibular angle reduction" and "reduction angleplasty" refer to operations to reduce the width of the lower face and change a square face to an oval one. Because the terms emphasize the word angle, however, they imply that the operations apply to the mandibular angle. The most frequent complaint after these operations is that the change in the lateral appearance is clear but that the change in the frontal appearance is not noticeable.

Mandibular osteotomies after drawing out the inferior alveolar nerve along the canal.

In some cases, the inferior alveolar nerve runs through a lower course than usual. In such cases, osteotomy of the mandible can injure the inferior alveolar nerves. In other instances, the course of the mandibular osteotomy can meet that of the inferior alveolar nerve.

Unexpected bleeding caused by arterial variation inferolateral to levator palpebrae.

When incisional or nonincisional double-eyelid operations are in process, unexpected bleeding adjacent to the lateral canthal area is often encountered. The unexpected bleeding may result in intraoperative hematoma and swelling. It may also cause temporary intraoperative ptosis.
