Balloon Sinuplasty: Certain patients may be candidates for Balloon sinus dilation. Sinus Balloons can enlarge the outflow tracts without the need for the removal of tissue. When used appropriately, sinus balloons can relieve symptoms with less bleeding and a shorter recovery. Most patients can undergo balloon sinus dilation in the office under local anesthesia. By atraumatically dilating the sinus openings, trapped mucus can be suctioned out of the sinus cavities and normal drainage pathways restored.
