Ligation of the sphenopalatine artery is used to treat severe nasal haemorrhage. Despite the high rates of success reported, errors and complications may occur in locating the sphenopalatine foramen (SPF) through which the vasculonervous structures penetrate the nasal cavity. Thus, the objective of this study was to investigate the numerical variation of the SPF, its relation to the ethmoid bone crista of the palatine bone in the lateral nasal wall, its distance from the anterior nasal spine and the angle between this distance and the anterior nasal floor.
