To describe the anatomy of sphenopalatine foramen (SPF) region and possible anatomical variations.Prospective study accomplished from September, 2006, to January, 2007.The 61 cadavers were carefully dissected. Presence ethmoidal crest, location accessory foramens, number arterial branches emerging through foramens observed. Data analyzed in relation gender, racial group, symmetry cadaver. Prediction presence was evaluated.Mixed race prevailed 122 nasal fossae dissected (75% males). Ethmoidal crest present 100% cadavers, being anterior SPF 98.4% cases. The most frequent transition middle superior meatus (86.9%). Mean distance spine 6.6 cm 6.7 cm, respectively. Accessory 9.83% A single stem emerged 67.2% cases, foramens. prevalence analyses showed no differences that statistically significant (P > 0.05) between gender group. a strong conformity < 0.01) location.
