Abstract:
Several systematic reviews and many clinical articles have shown that maxillary sinus floor elevation through lateral window approach (LSFE) is a predictable and reliable procedure, which has been routinely performed for more than 30 years. The complication rate is low, but some cases may require additional surgery, and the outcome of implant may be affected if not treated properly. The survival rates of implants are still high after early diagnosis and proper early treatments. The purpose of this article is to discuss the intraoperative and postoperative complications of LSFE, including perforation, bleeding, postoperative infection and implant displacement into sinus with special attention to prevalence rate, prevention and treatment.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
