After analysis of medical history and physical examination, the shape and extent of the disorder of the ear are evaluated and surgery-related road map is drawn. The anesthesiologist checks any obstacles before the operation and necessary blood tests are done before the surgery. In case of chronic diseases that may affect the operation, other additional tests or consultations may be necessary. If you use any blood-thinning medication it should be discontinued at least 1 week in advance the operation. Smoking can impair wound healing in some patients. There is no need to stop using drugs necessary for other chronic diseases.
