Figure 1: Schematic drawings explaining the chronology of events during the use of the surgical pneumatization of the Schneiderian membrane technique. (A) the lateral sinus wall and the Schneiderian membrane are perforated to create immediate ventilation of air (arrows in lateral direction). The procedure will overcome the overpressure of air within the sinus, hence facilitating the elevation of the Schneiderian membrane (B)
