The sinuses in the skull can become blocked and inflamed leading to pain and sometimes fever. The traditional surgical treatment for blocked sinuses was to use rigid instruments to enlarge the areas that drain the sinuses. A newer approach, which is shown in this animation, involves the insertion and inflation of a balloon to expand the sinus outlets. This approach is similar to balloon angioplasty used in damaged or blocked blood vessels.

Other Information

A lung biopsy removes a small piece of lung tissue which can be looked at under a microscope. The biopsy can be done in 4 ways. The method used depends on where the sample will be taken from and your overall health.

A lung biopsy is done to:

·                                 Diagnose certain lung conditions, such as sarcoidosis or pulmonary fibrosis. In rare cases, a lung biopsy may be done for severe pneumonia, especially if the diagnosis is not clear.

·                                 Diagnose suspected lung cancer.

·                                 Evaluate any abnormalities seen on other tests, such as a chest X-ray or a CT scan. A lung biopsy is usually done when other tests cannot identify the cause of lung problems.
