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. Key words: Schneiderian membrane, dental implants, lateral window, perforation, sinus augmentation.

ObjectiveThe purpose of this study is to compare the outcomes of using auto-transplanted tooth and flap for repairing sinus perforation after tooth extraction. The aim is to provide a new reference for selecting appropriate repair methods for maxillary sinus perforation.Methods and materialsThis study involved 19 patients with sinus perforation who underwent treatment at the Department of Oral Surgery, Hospital of Stomatology Wuhan University, from March 2021 to September 2022. The study included two groups: a test group with 11 cases where perforation of the maxillary sinus mucosa greater than 5 mm was found during autologous tooth transplantation, and a control group with 8 cases where maxillary sinus mucosa perforation greater than 5 mm was found during tooth extraction. Clinical examination and radiographic examination were taken at 2 weeks, 1, 3, 6, and 12 months post-surgery of two groups. The two-year survival probability of the AT group was assessed using Kaplan-Meier survival analysis.ResultsThe success rate of the auto-transplantation (AT) group was 72.7% (8/11), while the success rate of the flap transfer (FT) group was 100%. Upon analysis, it was found that the survival probability of AT group was significantly lower when the gingival index(GI) score was 2 (51.8%), in comparison to when it was 0 or 1 (100%).ConclusionThe study findings demonstrated that the utilization of auto-transplanted teeth yielded a favorable outcome in restoring maxillary sinus perforation, suggesting its viability as a potential option.

Maxillary sinus floor elevation is usually performed in two different ways: the lateral approach involves the creation of a bony window on the maxillary sinus lateral wall, providing direct access to the sinus cavity for membrane elevation and subsequent graft placement, and the transcrestal approach is considered less invasive. The aim of this article is to describe, based on the literature, how to anticipate, avoid, and manage the intraoperative complications that can occur with both approaches. For both approaches, the most common complication is the sinus membrane perforation. For the lateral approach, an average frequency ranging from 15.7% to 23.1% is reported, but because of the better visibility, their management will be easier compared to the transcrestal approach. Mean perforation rate reported for the transcrestal approach is lower (3.1%–6.4%), but it should be noted that a significant number of perforations cannot be detected and managed given the blind nature of this technique. Anatomical parameters such as sinus width and buccal wall thickness may be a risk factor for one approach and not the other. As it is impossible to assess the resistance of the Schneiderian membrane, the transcrestal approach is more likely to lead to infectious complications in the event of perforation. Others, such as the risk of vascular damage, are encountered only with the lateral approach, which can be prevented easily by dissecting the alveolo‐antral artery. For both approaches, prevention is essential and consists in analyzing the anatomy, mastering the surgical technique, and collaborating with the ENT to manage the essentially infectious consequences of intraoperative complications.
