If you have asthma, you may experience one or more of the following symptoms: Wheezing - A whistling sound heard when breathing in or out.

A mediastinoscopy may be performed on an outpatient basis or as part of your stay in a hospital. The procedure will be performed while you are asleep under general anesthesia. Procedures may vary depending on your condition and your doctorâs practices.
Test Overview. Mediastinoscopy is surgery to look at the inside of the upper chest between and in front of the lungs. This area is called the mediastinum. During the test, a doctor makes a small cut (incision) in the neck just above the breastbone or on the left side of the chest next to the breastbone. Then the doctor places a thin scope in the opening.
