The five year experience with endoscopic trans-septal frontal sinusotomy

Endoscopic trans-septal frontal sinusotomy (TSFS) represents a unique surgical approach to the floor of the frontal sinus. Although the final result can have similarities to the modified Lothrop procedure in that the intersinus septum may be drilled out, endoscopic TSFS represents a novel approach that can be valuable in patients with certain anatomic configurations. Endoscopic TSFS represents an alternate approach to the frontal sinus that may be used by the experienced endoscopist to augment treatment of refractory frontal sinus disease. This procedure is best considered for patients with favorable anatomy who have significant frontal sinus disease and cannot be managed adequately through an endoscopic frontal sinusotomy.
