Presence of the ethmoidal crest, location of sphenopalatine and accessory foramens, and the number of arterial branches emerging through foramens were observed. Data were analyzed in relation to gender, racial group, and symmetry of the cadaver. Prediction of the presence of accessory foramen was evaluated.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Mixed race cadavers prevailed in 122 nasal fossae dissected (75% males). Ethmoidal crest was present in 100% of the cadavers, being anterior to the SPF in 98.4% of the cases. The most frequent SPF location was the transition of the middle and superior meatus (86.9%). Mean distance from the SPF and accessory foramen to anterior nasal spine was 6.6 cm and 6.7 cm, respectively. Accessory foramen was present in 9.83% of the cases. A single arterial stem emerged through the SPF in 67.2% of the cases, and 100% through accessory foramens. The prevalence analyses showed no differences that were statistically significant (<jats:italic>P<\/jats:italic> &gt; 0.05) between gender and racial group. The symmetry analyses showed a strong conformity (<jats:italic>P<\/jats:italic> &lt; 0.01) between nasal fossae in relation to the SPF location. There was no statistically significant conformity between nasal fossae and accessory foramen (<jats:italic>P<\/jats:italic> = 0.53). None of the variables of interest presents any statistically significant (<jats:italic>P<\/jats:italic> &gt; 0.05) association with the presence of the accessory foramen.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> There are anatomical variations in the lateral nose wall that should be considered for successful endoscopic surgical treatment of severe epistaxis.<\/jats:p>","DOI":"10.1097\/mlg.0b013e31815708d0","type":"journal-article","created":{"date-parts":[[2009,2,19]],"date-time":"2009-02-19T21:43:58Z","timestamp":1235079838000},"page":"156-161","source":"Crossref","is-referenced-by-count":45,"title":["Severe Posterior Epistaxis\u2013Endoscopic Surgical Anatomy"],"prefix":"10.1002","volume":"118","author":[{"given":"Francini G.
