Abstract:
The most commonly reported complication during the sinus elevation surgical procedure is the perforation of the Schneiderian membrane. The aim of this retrospective study was to compare the rate of sinus membrane perforation during lateral window augmentation using either conventional sinus curettes or medical-grade polyurethane sponges. This retrospective study included patients who received a lateral window approach for sinus floor elevation. The sinus elevation procedures using medical-grade polyurethane sponges (test) or conventional curettes (control) were recorded and analyzed. All subjects' demographic data and preexisting conditions were evaluated. A total of 38 procedures met inclusion criteria, and those data were evaluated for analysis. There were no statistically significant differences in demographic data or preexisting conditions including age, sex, treatment location, presence and absence of septum, Schneiderian membrane thickness, and residual bone height between test and control groups. The membrane perforation rate was 7% in the test group and 43% in the control group; however, this difference did not reach statistical significance (P = .064). Within the limitations of this study, although there was no statistically significant reduction of sinus membrane perforation with the use of medical-grade polyurethane sponges, the decreased incidence of perforation might be of clinical significance.
Insights
Medical-grade polyurethane sponges may reduce sinus membrane perforation during sinus elevation surgery. While not statistically significant, the observed lower perforation rate suggests potential clinical benefits for this common surgical complication.
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.
