Incidence, Risk Factors, and Complications of Schneiderian Membrane Perforation in Sinus Lift Surgery: A Meta-Analysis.

摘要: Objectives To evaluate the incidence of Schneiderian membrane perforation occurring during sinus lift surgery, and to investigate possible risk factors associated complications. Materials methods A systematic search for papers published between 1975 2015 was performed in MEDLINE, EMBASE, Scopus, Web Science, Trip, Cochrane Oral Health Group's Trials Register, Central Register Controlled Trials, ProQuest Dissertations & Theses. The quality assessment each study using GRADE system. All extracted data were synthesized either fixed or random effect models as indicated. Results Out 1652 surgeries reported 12 studies, 388 perforations occurred. weighted rate 23.5% ranging from 3.6% 41.8%. Both reduced thickness septa increased perforation. difference implant survival rates perforated nonperforated side not significant (P = 0.24). use piezoelectric instrumentation appears reduce risk. Conclusions With an ratio 1:4, is a common surgical complication surgery. We should keep mind that appropriately handled treated tends show comparable when compared with intact membrane.
