This surgery is not often performed now.</p><p style="margin: 0px 0px 13.33px;">You will receive general anesthesia, so you will be asleep and pain free. The surgeon will make a cut behind the ear. A bone drill will be used to gain access to the middle ear cavity that is behind the mastoid bone in the skull. The infected parts of the mastoid bone or ear tissue will be removed and the cut is stitched and covered with a bandage. The surgeon may put a drain behind the ear to prevent fluid from collecting around the incision. The operation will take 2 to 3 hours.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Why the Procedure is Performed</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
