摘要

Purpose

Perforation of the sinus membrane is a common complication during maxillary sinus lift surgery. This systematic review aimed to evaluate if the residual ridge height (RRH) is a risk factor for membrane perforations during the lateral-window sinus lift surgery.

Methods

PubMed, Embase, CENTRAL, Scopus, and Web of Science databases were searched for studies reporting the association between RRH and sinus membrane perforations during the lateral-window sinus lift surgery. The last date of the search was 17th June 2024.

Results

Ten studies were eligible. 1601 patients undergoing 1809 sinus lift procedures were included in the studies. The overall sinus membrane perforation rate was 19.2%. The meta-analysis found that mean RRH was significantly lower in the perforation group than the non-perforation group (MD: -0.89 95% CI: -1.47, -0.31 I2 = 90%). The included studies classified Small RRH as a 3–4 mm ridge. Meta-analysis showed a tendency of increased risk of perforation with small RRH, but the difference was not statistically significant (OR: 2.47 95% CI: 0.49, 12.21 I2 = 88%). The exclusion of one outlier study showed statistically significant results.

Conclusions

Small RRH seems to be a potential risk factor for sinus membrane perforation during lateral-window sinus lift surgery. More evidence is needed for improving the validity of the current results.
