This review discusses the principles of maxillary sinus repair consisting of anatomy and physiology of the sinus, signs for surgical treatment, preoperative assessment, medical techniques, and management of complications. MEDLINE, AMED, EMBASE, CINAHL, and the Cochrane Library were searched in details (for articles published up to December, 2018) for relevant articles in English language were included in the review. The maxillary sinus lift has, over the last 30 years, been established as an approved standard for treatment of the edentulous maxilla. Alternatives such as short implants, although revealed to be effective in the short term, lack long-lasting researches to sustain regular use. The maxillary sinus elevation treatment making use of a side window approach has been revealed to be one of the most effective bone enhancement procedure that is done as a pre-prosthetic treatment prior to implant placement. When success is measured by patient result (success of the implanting procedure), the superb result rate accomplished is due to the fact that issues are very little and potentially better on avoided through correct situation option, excellent surgical method, and correct and prompt handling of intraoperative and postoperative problems.
