This paper presents two cases of umbilical reconstruction using a reverse fan-shaped flap. In both cases, the umbilicus was lost during surgical procedures on the abdominal wall when the patients were(More)
Human hand can not only catch and grasp the complex objects but also easily manipulate the objects by switching various types of interactions. Research on the basic mechanics and control principles of hand's dexterous manipulation abilities is one of the most important subjects in biomimetics. In this paper, by considering the multicontact manipulation(More)

However, the unfortunate patient who presents with complication of the nasal implants and wants to remove them is vexed with a significant resultant cosmetic defect if the implant is removed.

For vascular anastomosis, we(More)
