“…[39][40][41] This may either be done by an additional lateral sinus augmentation in the region of the primary graft or via a transcrestal access or combined.

Background Maxillary sinus membrane perforation (SMP) during lateral window sinus floor elevation (SFE) might be associated with postoperative complications (PC). Objectives To evaluate the prevalence of PC and clinical implant outcome for different forms of SMP with lateral window SFE. Material and Methods The prevalence of PC such as maxillary sinusitis, graft necrosis and wound infection was retrospectively evaluated for 434 lateral window SFE (334 patients) with 331 SFE (241 patients) without and 103 SFE (93 patients) with SMP. SMP was additionally classified into four subgroups regarding to membrane perforation size (small‐moderate [<10 mm] vs. large [>10 mm]) and membrane biotype ([BT] thin vs. thick). Additionally, patient‐ and surgery‐related risk factors affecting PC and the 1‐year implant survival rate were evaluated for SFE without and with SMP and subgroups. Results A significantly higher prevalence including significant odds ratios of PC such as maxillary sinusitis (10/103 [9.7%] vs. 4/331 [1.2%]; p < 0.021; OR: 8.85; p < 0.021) and graft necrosis (7/103[6.8%] vs. 1/103[0.3%]; p < 0.017; OR:7.43; p < 0.017) was found for SFE with than without SMP. The SMP subgroup with large size and thin BT involved significantly (p < 0.005) more PC (15/20[75%]) than all other SMP subgroups (5/20[25%]). For the risk factors evaluated the univariate analysis demonstrated differences of PC for the presence versus absence of SMP (p < 0.001) and for thin versus thick sinus mucosa (p < 0.038; p < 0.006) but not for sex, smoking, sinus septa and surgical stage. In the multivariate risk factors analysis, PC were significantly related to risk factors such as large size with thin BT (OR:18.049; p < 0.007). The 1‐year implant survival rate did not differ between SFE without (99.5%) and with SMP (99.1%), regardless of successfully repaired subtype of SMP. Conclusion The synopsis of perforation size and membrane biotype is crucial in differentiating different forms of SMP assessing and anticipating different prevalences of PC in lateral window SFE.

Maxillary sinus floor elevation, via the lateral approach, is one of the most predictable bone augmentation procedures performed in implant dentistry. but both intra‑ and postoperative complications can occur, and some of them are severe. Our aim is as follows: To review the pertinent literature on the topic, especially assessing the risk factors related to complications. To give clinical recommendations to minimize intra‑ and postoperative complications with the ultimate scope of improving the standard of clinical care and patient safety.

Particulate ramal bone graft for longstanding oroantral fistula closure on sinusitis

An oroantral fistula refers to an abnormal connection between the oral cavity and the maxillary sinus, which can result in chronic maxillary sinusitis. Combining a buccal fat pad and buccal advancement flap has certain limitations when correcting bone defects and providing prosthetic rehabilitation supported by implants. Autografts have been recommended, particularly for larger defects or when conservative methods are ineffective. This case report describes particulate autogenous bone grafts with a pouch graft technique to address a longstanding oroantral fistula and chronic sinusitis that did not improve after endoscopic sinus surgery. The proposed approach using particulate autogenous bone grafts with a pouch graft technique offers a solution for successfully closing the fistula and resolving the symptoms related to sinus issues. Oroantral fistulas need to be managed to prevent complications. Further research will be needed to evaluate the long-term ability of this method to regenerate bone.
