Resection of a prominent mandibular angle is commonly used in Eastern society to improve the lower one third facial proportion. Historically, this procedure had a high complication rate, such as severe bleeding, asymmetry of the angle reduction, and "second mandibular angle." A safer and more effective way of performing such procedures is needed. The aim of this study is to introduce 3 instruments, a tunable guide handpiece, milling cutter, and flywheel, which were invented by the author, as well as a related ostectomy technique for correcting prominent mandibular angles using a modified full-thickness marginal ostectomy of the mandibular corpus angle, named the "stamp perforation" technique. This technique has 4 highlights: First, it ensures a smooth symmetric contour. Second, it prevents the risks of rupture of the inferior alveolar vessel and facial artery, ensuring the safety of this approach. Third, the "stamp perforation" technique eases the removal of bone fragments, shortening the operation time. Fourth, the recovery time of patients treated with this approach is much shorter than with the traditional approaches. From January 2006 to January 2016, 1106 patients underwent the surgery to contour the prominent mandible angles, and satisfactory results were achieved. Thus, we recommend the instruments as well as the "stamp perforation" technique for correcting prominent mandibular angles, and we hope that our 10 years of experience could provide a reference for other plastic surgeons.

Facial aesthetics involve basic artistic principles that relate individual features to the face as a whole. These principles, such as balance and proportion, are key elements in the development of hair restoration surgery and can be applied to reconstructive procedures for the trauma or burn patient. This paper describes the application of anthropometric and artistic principles used in hair reconstruction. Attention has been directed to the procedures used to determine hairline contour and placement, and certain aspects of frontotemporal recession management. The frontal hair has a profound effect on facial balance because of the major role hair plays in framing and visually enhancing the face. The presence of frontal hair and facial framing also serves to retain a vital element of autonomy in appearance for the individual.

Patients with Treacher Collins syndrome were studied regarding 10 nasal, 1 orbital, and 4 facial measurements as well as 10 facial proportion indexes. Data from 15 to 24 patients were related to normal values. The most normal feature was found to be the nose, whose basic measurements were optimal. Because harmony between the nose and the face is a basic requirement of aesthetic balance in a healthy face, the nose in these patients is the key for calculating changes in the markedly damaged general framework of the face. Abnormal proportion indexes must be corrected by adjusting the abnormal measurement to its optimal level. Thus, the abnormally short bizygomatic width had to be increased by a mean of 13 to 21 mm. Both the nose and the face were usually normal-long, producing acceptable proportions in these patients. Some size disproportions were found between the root and the soft nose. Their adjustment should be part of the general plan to correct the face of a patient with Treacher Collins syndrome.
