OUR CASE STUDY IS A 54-YEAR-OLD PROFESSIONAL MALE EXPERIENCING MINOR SINONASAL COMPLAINTS FOR MORE THAN A DECADE. Our technique is a step-by-step approach to a complete left antrostomy, sphenoethmoidectomy, and frontal recess surgery (Draf 2a). This “simple” sinus cavity is the foundation upon which all other endoscopic interventions are based. The key maneuvers are to define the orbit along its entire length, from medial wall to orbital apex/optic nerve canal. Secondly, the skull base is identified with great certainty by locating it in the sphenoid and defining its transition to the posterior table of the frontal sinus. Where possible, dissection occurs posterior and inferior first, so that bleeding does not occur onto the surgical field.
