Mastoid foramen (MF) is an accident located at the posterior part of temporal bone, near occipitomastoid suture. We studied 350 dry human skulls (700 sides) without identification of sex or race, belonging to the Anatomy lab of Institute of Science and Technology, São Paulo State University (Unesp), Campus São José dos Campos. Some characteristics about MF were observed and we also studied the classification of the skulls using the cranial index. We analized the presence/absence of MF, its incidence regarding to the side, number of forams in each skull and in each side of the skull, the MF's location regarding to the occipitomastoid suture and to the Frankfurt plane, the distance of each foramen to this plane and the measures of the súpero-inferior and lateral-lateral diameters of each MF. The results have been statistically analized and the existence of a relationship between what we found and the classification of the skulls was observed. We found dependence relationships between the cranial index and the DSI (the measures were statistically higher in the mesocephalic skulls) and between the index and the location regarding to Frankfurt plane, on the right side of the skulls (in most cases, the forams found in different locations on the same side were present on the mesocephalic skulls). The anatomical and morphometric knowledge about MF and the relations of this structure with surgical repair areas are very useful in the studies about the hominid evolution and in surgical procedures at mastoid region
