This video demonstrates a sinus elevation technique using the lateral approach. For maxillary sinus membrane elevation, there are two broad techniques: lateral approach (direct) or the crestal approach (indirect or sometimes called Summers approach). The Lateral sinus lift, has some disadvantages, in that it is more aggressive, requires greater surgical skill and has a longer healing period. However, in many cases it is still the best available solution for insufficient quantity of the alveolar bone. When performed according to proper surgical protocol the risk of complications remains low.
