surgery of the maxillary sinus in procedures as elevation of the sinus membrane and bone graft, with or without simultaneous implants in the subantral area, is becoming a more standard procedure in oral implants each time. one of the most common complications in this type of procedure is the approach of the sinus lateral wall, with presence of undiagnosed intra-sinus septa with perforation of the membrane during sinus elevation. the presence of septa in the maxillary sinus is variable, presenting as single or multiple in different locations with relation to the rots in maxillary pieces in dentate or edentulous patients. various authors have described different values in the prevalence of the intra sinus septum presence, based on three dimensional imaging studies, or the in vivo study of cadavers. the aim of this study is an exhaustive review of the literature since 1997 to november of 2010 in reference to the prevalence of maxillary sinus septa and their location according to observation methods, and the report of a case with innovative surgical approach technique, that allows intra and extra sinus visualization for in vivo maxillary sinus septum location.
