Percutaneous transnasal sphenoidotomy with sphenoid window.

Abstract

Ten percutaneous transnasal sphenoidotomies were performed in nine children; and in seven, a sphenoid window was also created. All procedures were performed in the special procedures laboratory, with biplane fluoroscopic guidance used in each case. Under general anesthesia, with the child in the supine position, a 14-gauge antral trocar was placed transnasally into the sphenoid sinus. The sinus was aspirated and material was obtained for culture. A Takahashi forceps was placed via the same tract into the sphenoid sinus. The cusps were centered across the anterior cortex, and under fluoroscopic visualization, opened and rotated 360 degrees, creating a sphenoid window. All procedures were completed without complication, and no child required further surgery.
