Application of Dual "Kite" Myomucosal Flaps for the Repair of Medium Lip Defects.

OBJECTIVE: To investigate the application of dual "kite" myomucosal flaps (subcutaneous pedicle advancement flap) for the repair of medium lip defects (one-third to one-half lip width). METHODS: Dual kite myomucosal flaps were designed in the adjacent area of the defect in 17 patients with medium lip defect with the principle of using homogenous tissue as far as possible without affecting local anatomical units. RESULTS: The follow-up time was 3 to 24 months; 16 patients showed primary wound healing, and 1 patient showed prolonged healing. The blood supply of the myomucosal flaps were reliable. The myomucosal flaps were smooth, with no proliferation of scars, and the local appearance was good. CONCLUSION: The dual kite myomucosal flaps provide a reliable method for repairing medium lip defects, decreasing the need for additional excision of normal skin tissue, and reducing skin scar.

Epidemiological Investigation of Facial Soft Tissue Injury in Chinese Preschool Children.

OBJECTIVE: The aim of this study was to analyze the epidemiological characteristics of pediatric facial soft tissue injuries of Chinese preschool-aged children in Hangzhou Plastic Surgery Hospital. METHODS: Medical records of preschool-aged children's facial injuries, 6 years and younger, from January 2017 to December 2019 were collected. Sex; age; time of injury; length of stay; causes of injury; location, type, length, and depth of wound; anesthesia methods; and treatment and evaluation of postoperative scars were analyzed. RESULTS: There were 10,862 cases (male, 6780 cases; female, 4082 cases) in the group. The ratio of male to female was 1.66:1. Mean age was 3.4 (±1.6) years; the youngest was 1 month old. The time of injury occurred frequently between 9:00 and 13:00 and 16:00 to 21:00, with the most common incident time being between 19:00 and 20:00. Collision injury was the main cause of injury (9822 [90.43%]). The most frequently injured area was the forehead (4874 [44.87%]). The main form of injury was laceration wound (9721 [89.45%]). The depth of injuries was mainly middle layer (adipose or muscular layer) (6299 [57.99%]). The length of injuries was 1.7 (±0.9) cm, ranging from 0.2 to 10.5 cm. Furthermore, 9110 cases were repaired by plastic surgeries and 1 or more antiscar measures. After 6-month to 2-year follow-up, 9 cases of animal scratch or bite, lip penetrating wound, or bumping teeth were infected and 26 cases had scar hyperplasia. The others achieved satisfactory results, and the scars were not obvious. CONCLUSION: Preschool-aged children's facial injuries have predictable patterns of occurrence, and targeted preventive measures can reduce the incidence rates. After facial injury, children should present for timely plastic surgery treatment and accept combined antiscarring measures to minimize postoperative scarring.

Leveraging Two Kinect Sensors for Accurate Full-Body Motion Capture.

Accurate motion capture plays an important role in sports analysis, the medical field and virtual reality. Current methods for motion capture often suffer from occlusions, which limits the accuracy of their pose estimation. In this paper, we propose a complete system to measure the pose parameters of the human body accurately. Different from previous monocular depth camera systems, we leverage two Kinect sensors to acquire more information about human movements, which ensures that we can still get an accurate estimation even when significant occlusion occurs. Because human motion is temporally constant, we adopt a learning analysis to mine the temporal information across the posture variations. Using this information, we estimate human pose parameters accurately, regardless of rapid movement. Our experimental results show that our system can perform an accurate pose estimation of the human body with the constraint of information from the temporal domain.
