Partial anterior ethmoidectomy involves an infun-dibulotomy including a partial resection of the anterior ethmoid air cells. The infundibulotomy can be extended to open the anterior ethmoidal cells, to the basal lamella, and to open the agger nasi air cells, but not to open them entirely as this would mean instrumenting the frontal recess. A key point is to avoid instrumenting the frontal recess as this runs the risk of causing stenosis (Fig. 5.29). lT/l* 7, 8
