Few reports exist on effective methods of evaluating the effects and selecting indications for the treatment of improving facial morphology by masseteric injection of botulinum toxin type A. The method for selecting indicative factors, as determined by the change of masseteric area volume at a standard frontal view when tightly clenching teeth, was used in(More)
Lung cancer is the leading cause of cancer mortality worldwide, and the cause of death is metastasis. The epithelial-to-mesenchymal transition (EMT) plays a key role in the process of metastasis. Macrophages within the lung cancer microenvironment release cytokines, such as interleukin-6 (IL-6), and promote lung cancer cell invasion and metastasis. However,(More)
The fuzzy Petri net (FPN) is a new kind of Petri nets that is well developed in recent years. It is difficult to model and simulate the fault diagnosis of batch process because of the alternation between the discrete states and the continuous process. This paper concerned with a new method of complex batch process fault diagnoses based on fuzzy Petri nets.(More)
INTRODUCTION Post-traumatic ear reconstruction still remains a great challenge for plastic surgeons. In this article, we present the technique of post-traumatic ear reconstruction using a postauricular fascial flap combined with an expanded skin flap. METHODS From May 2007 to June 2009, 91 cases of post-traumatic ear defect were treated using a(More)
OBJECTIVE The study aimed to explore a new method to restore functional and cosmetic outcomes for anterior neck burn scar contracture. METHODS Tissue expanders were implanted subcutaneously under the muscle of the forehead. Tissue expansion started 1 week postoperatively. When the skin expansion finished, a bilateral pedicled expanded skin flap was(More)
Pioneers such as Tanzer and Brent have established the foundations of microtia reconstruction using an autogenous costal cartilage framework. The framework and its skin coverage are the two limiting factors in ear reconstruction. At the present time autogenous rib cartilage and mastoid skin are still first choice materials for most surgeons. They have the(More)
In order to enhance the dexterity of surgical instruments in robotic-assisted minimally invasive surgery, the robot is generally configured so as to have a wrist. However, this configuration has a problem in that there is a coupling of the motions of the wrist and the end-effector. In this paper an improved surgical instrument is proposed that eliminates(More)
OBJECTIVE To explore the clinical effect of the method by using an expanded post-auricular skin flap combined with autologous rib cartilage framework for correction of concha-type microtia. METHODS The operation were performed in three stages. The expander was implanted under post-auricular skin at the first stage and expanded skin flap was formed. At the(More)
This paper developed a simulation system for the training minimally invasive surgery (MIS). The simulation system has the capacity of providing the user with the security and real learning environment. The simulation system adopted Omega7 force sensing device as the input equipment offering position and posture information to the virtual robot. On the basis(More)
OBJECTIVE To explore the incidence, degree, and pattern of rib cartilage calcification in congenital microtia patients, in order to provide reference for harvesting the rib cartilage, sculpturing cartilage framework. METHODS From Jun. 2013 to Nov. 2014, 383 patients (age range, 6-45 years) underwent CT scans of the chest. 11 patients with bony diseases or(More)
