Does sinus membrane thickness influence the risk of perforation during lateral sinus lift surgery for dental

Background:
We reviewed the literature to examine if the thickness of the sinus membrane is a risk factor for perforation during lateral sinus lift surgery.
Material And Methods:
We searched Embase, PubMed, and Web of Science databases till 4th December 2023 for studies examining the risk of perforation with different sinus membrane thicknesses. Studies reporting sinus membrane thickness in perforation and non-perforation cases were also included.
Results:
Eleven studies were eligible. All studies used cone beam computed tomography for measuring sinus membrane thickness. Meta-analysis showed that sinus membrane thickness was significantly lower in perforation cases as compared to non-perforation cases (MD: -0.91 95% CI: -1.48, -0.33 I2=94%). Four studies used 2mm as the cut-off to define thick and thin sinus membranes. Pooled analysis failed to demonstrate any significant difference in perforation rates (OR: 0.97 95% CI: 0.44, 2.17 I2=56%). Meta-analysis of studies using 1.5mm (OR: 0.66 95% CI: 0.29, 1.48 I2=72%) and 1mm cut-off (OR: 0.93 95% CI: 0.34, 2.56) also demonstrated similar non-significant results.
Conclusions:
Our study shows that the sinus membrane is significantly thinner in cases with perforations as compared to those with no perforations. However, a meta-analysis based on different membrane thickness cut-offs failed to demonstrate a relationship between thinner sinus membranes and a higher risk of perforation. There is a need for further studies examining the role of sinus membrane thickness on perforation rates.
