Sphenoid sinus cyst: 0 ° endoscopic laser ablation of the posterior part of the middle turbinate anterior sphenoid sinus exposure, locate the sphenoid sinus opening as a center around the laser ablation of sinus mucosa, point by point to bite than an open sinus bone, laser resection wall. Frontal sinus cyst: a thorough screening before opening fully open frontal sinus openings, in the 30 ° endoscope to the bottom wall of the frontal sinus expanding bite addition to bone, laser ablation of the wall.
