OBJECTIVE Prominent ears are a common congenital deformity of the external ear, derived from a combination of defects in the antihelix and concha. The majority of cases are treated surgically, but one of major difficulties associated with otoplasty regards the achievement of lasting aesthetic results. With the present study we propose an effective combination of four surgical techniques of cart...

46 people participated in the study. The participants were randomly divided into 3 groups as Above Threshold, Under Threshold and Control according to sensation of electrical current on ears. evaluated times; before application, after first second bicycle exercises. Numerical pain scale, pulse rate, blood pressure, respiratory distance travelled during exercise for cycle ergometer test.

 Many chronic wounds have a limited blood supply and contain necrotic tissue that must be debrided. The effect of collagenase, an enzymatic debriding agent, has been studied in acute but not in chronic wounds. The purpose of this in vivo study is to evaluate the effect of collagenase on wound healing in ischemic wounds. The ears of eight young New Zealand White rabbits were rend...

INTRODUCTION External ears, one of the major face components, show an interesting movement during craniofacial morphogenesis in human embryo. The present study was performed to see if movement of the external ears in a human embryo could be explained by differential growth. METHODS In all, 171 samples between Carnegie stage (CS) 17 and CS 23 were selected from MR image datasets of human embry...

Preparation and in vitro characterization of floating microparticles loaded with cimetidine (FMC) for oral delivery was the objective of this study. Non-solvent addition coacervation technique using hydroxypropylmethylcellulose (HPMC) as the rate controlling polymer was employed to achieve FMC. Three formulations of FMC were prepared and optimized regarding encapsulation efficiency and dissolut...
