Endoscopic sphenoid nasalization for the treatment of advanced sphenoid disease.

摘要

In most cases of sphenoid sinusitis, enlargement of the obstructed sinus ostium is sufficient to provide drainage of retained secretions and reestablish mucociliary clearance. In the setting of failed prior sphenoidotomy or advanced disease, however, conventional sphenoidotomy may prove inadequate to address the pathologic condition at hand. In such instances, sphenoid nasalization may be utilized to widely open the sphenoid sinus, providing enhanced intraoperative exposure, postoperative drainage, and long-term surveillance.
