I had surgery to open up my cyst in my back. i have a hole. should i air it out for a bit as it heals or keep it covered with gauze?

Clean and Dry: It depends on the condition of the wound. It needs to be kept very clean and dry. Since clothing will touch the open area a loose gauze with neosporin can be used. It should be changed daily.

Open drainage: The answer depends on the underlying cause of the problem. If you have an infection it is very important that the wound be allowed to drain. Usually such wounds are managed with an absorbent dressing (gauze) and dressing changes. The doctor who did the surgery should guide you and give you specifics for your situation.
