It's a frightening prospect after a nasal or sinus surgery to entertain the idea that you might have a serious complication known as empty nose syndrome (ENS). It will make you sick just thinking about it. Adding confusion to the mix is that some temporary complications are similar to ENS including dryness, crusting, bleeding, and congestion. And, let's face it, you really should not worry about having ENS until some time has passed. Dr. Steven Houser of Cleveland, Ohio, for example, who is well-versed in treating ENS patients, won't diagnose someone as having ENS until a full year has passed after the turbinate reduction surgery.
