Association between lateral wall thickness and sinus membrane perforation during lateral sinus elevation: A...

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Anatomy

Background:

• Sinus membrane perforation is a complication during lateral wall sinus elevation.
• Understanding factors influencing perforation is crucial for surgical success.

Purpose of the Study:

• To investigate the relationship between maxillary sinus lateral wall thickness and sinus membrane perforation incidence.

Main Methods:

• Retrospective review of CBCT scans and patient records from sinus elevation procedures.
• Measurement of lateral wall thickness at 4mm and 6mm coronal to the sinus floor.
• Correlation analysis between wall thickness and perforation occurrence.

Main Results:

• Mean lateral wall thickness was 1.59mm (4mm coronal) and 1.58mm (6mm coronal).
• Perforation group showed significantly thicker walls (2.43mm and 2.41mm) compared to non-perforation group (1.21mm and 1.23mm).
• Perforation rates were 56.4% (≥2mm thickness) vs 12.1% (≤1mm thickness) at 4mm coronal.

Conclusions:

• Maxillary sinus lateral wall thickness is significantly associated with sinus membrane perforation.
• Thicker sinus lateral walls are a predictor of increased perforation risk.
