A previous publication by this author discussing complications of endoscopic intranasal ethmoidectomy indicated an overall complication rate of 29% in 90 patients (17% in 150 ethmoidectomies). Compared to published complications rates for traditional intranasal ethmoidectomy (2.7% to 3.7%), 17% is alarming and of concern. The complication results in 300 ethmoidectomies performed on 180 patients are presented. The overall complication rate was 9.3%. Only two further complications have occurred since the first reported series: a cerebrospinal fluid leak and one case of subcutaneous emphysema. Methods and techniques that have led to the reduction of complications are briefly discussed. Endoscopic ethmoidectomy is a valid, safe procedure in experienced hands.
