I will chime in as an MS for what it is worth. Others in your situation have worked in labs for 2-3 years with an influentuial figure in plastic surgery and then tried to match. It is not always successful but it appears to work. Some names of people with a strong research interest and a powerful voice include Losee, Longaker, and Steve Warren. If this does not get you directly in, it may halp to procure a general surgery postion which can lead to PRS.
