Effect of Medical-Grade Polyurethane Sponges on Sinus Membrane Perforation With a Lateral Window Approach

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Surgical Complications

Background:

• Sinus membrane perforation is a frequent complication during sinus elevation procedures.
• The lateral window approach is a common technique for sinus floor elevation.
• Minimizing intraoperative complications is crucial for successful sinus augmentation.

Purpose of the Study:

• To compare the rate of sinus membrane perforation using conventional curettes versus medical-grade polyurethane sponges.
• To evaluate the efficacy of polyurethane sponges in reducing perforation during lateral window sinus augmentation.

Main Methods:

• Retrospective study analyzing 38 lateral window sinus elevation procedures.
• Comparison between procedures using medical-grade polyurethane sponges (test group) and conventional curettes (control group).
• Analysis of demographic data, preexisting conditions, and perforation rates.

Main Results:

• The membrane perforation rate was 7% in the polyurethane sponge group and 43% in the curette group.
• No statistically significant difference in perforation rates was found (P = .064).
• Demographic data and preexisting conditions were comparable between the groups.

Conclusions:

• Medical-grade polyurethane sponges showed a trend towards reduced sinus membrane perforation.
• Although not statistically significant, the observed decrease in perforation may hold clinical significance.
• Further research is warranted to confirm the potential benefits of polyurethane sponges in sinus elevation.
