This case series is aimed to report a new phenomenon, the "dome phenomenon," which was observed in infected augmented sinuses over several years.
Five patients are presented in whom sinus lift augmentation resulted in postoperative infection with inflammation and suppuration. The patients received aggressive anti-inflammatory treatment and surgical debridement of the inflamed tissue, including some grafted material performed through the lateral window of the primary procedure.
The inflammatory condition was reversed, and the site healed clinically. Radiographically, a dome-shaped, radio-opaque tissue was observed at the superior most aspect of the grafted sinus. This "dome phenomenon" was further confirmed during dental implant placement, which indicates healing potential adjacent to the maxillary sinus membrane.
The current report, as well as other studies and case series, suggests that there is great potential for healing and bone formation in the maxillary sinus membrane. The precise mechanism is not known. Further clinical and histologic studies are needed to understand the regenerative potential of the Schneiderian membrane.
本病例系列旨在报告一种新现象，即“穹顶现象”，该现象在数年内观察到感染的鼻窦增大。
报告了 5 例患者，他们在接受鼻窦提升增大手术后出现感染、炎症和化脓。患者接受了积极的抗炎治疗和对发炎组织进行手术清创，包括通过初次手术的侧窗切除一些移植物。
炎症状况得到逆转，临床治愈。影像学检查显示，在移植物鼻窦的最上方观察到穹顶状、不透射线的组织。在牙种植体植入时进一步证实了这种“穹顶现象”，这表明上颌窦膜附近有愈合潜力。
目前的报告以及其他研究和病例系列表明，上颌窦膜有很大的愈合和骨形成潜力。确切的机制尚不清楚。需要进一步的临床和组织学研究来了解施氏膜的再生潜力。
