In the atrophic posterior maxilla, successful implant placement is often complicated by the lack of quality and volume of available bone. In these cases, sinus floor augmentation is recommended to gain sufficient bone around the implants. Sinus elevation can be performed by either an open lateral window approach or by a closed osteotome approach depending on available bone height. This case series demonstrates the feasibility and safety of minimally invasive antral membrane balloon elevation, followed by bone augmentation and implant fixation in 20 patients with a residual bone height of 2 to 6 mm below the sinus floor. The surgical procedure was performed using a flapless approach. At 18 months follow-up, the implant survival rate was 100%. Absence of patient morbidity and satisfactory bone augmentation with this minimally invasive procedure suggests that minimally invasive antral membrane balloon elevation should be considered as an alternative to some of the currently used methods of maxillary bone augmentation.
在萎缩性上颌后区，由于缺乏质量和可用骨量，成功植入物的放置常常变得复杂。在这些情况下，建议进行鼻窦底增高术以在植入物周围获得足够的骨量。根据可用骨高度，可以通过开放式外侧窗入路或闭合式骨凿入路进行窦提升。本病例系列研究证明了微创经窦内隔膜球囊提升术的可行性和安全性，随后对 20 名剩余牙槽骨高度在窦底下方 2 至 6 毫米的患者进行了骨增量和植入物固定。手术采用无瓣入路进行。18 个月随访时，种植体存活率为 100%。该微创方法无患者发病且具有令人满意的骨增量，提示微创经窦内隔膜球囊提升术可作为目前上颌骨增量一些方法的替代方法。
