背景已有报道通过简单地提升上颌窦膜并在窦腔内填充血块来诱导鼻窦底隆起骨形成。目的探讨应用患者自身的静脉血结合鼻窦膜隆起术进行上颌窦底隆起术的可行性。材料和方法在6只成年雌性杂种犬的上颌窦内放置一个在窦膜隆起术后向上颌窦突出8 mm的种植体。膜和窦底之间的间隙被从每只狗身上提取的自体静脉血填充。结果在实验过程中，种植体腔塌陷，窦膜脱落。在塌陷的膜形成的间隙中有少量的新骨形成。鼻窦种植体周围新生骨的平均高度：颊侧为2.7+/-0.7 mm，腭侧为0.6+/-0.3 mm。结论初步研究结果表明，血液凝块的完整性不足以使鼻窦膜在一段时间内保持在隆起的位置。因此，建议仅当上颌窦腔内种植体周围需要少量新骨形成时才使用该方法。引用本文：Kim H-R，Choi B-H，Xuan F，Jeong S-M。自体静脉血用于上颌窦底扩大联合鼻窦膜提升：一项实验研究。口头实施。网址：10.1111/j.1600-0501.2009.01855.x.
BackgroundThere have been reports of successful bone formation with sinus floor elevation induced by simply elevating the maxillary sinus membrane and filling the sinus cavity with a blood clot.PurposeWe investigated the feasibility of maxillary sinus floor augmentation using the patient's own venous blood in conjunction with a sinus membrane elevation procedure.Materials and methodsAn implant that protruded 8 mm into the maxillary sinus after sinus membrane elevation was placed in the maxillary sinus of six adult female mongrel dogs. The resulting space between the membrane and the sinus floor was filled with autologous venous blood retrieved from each dog. The implants were left in place for 6 months.ResultsDuring the experimental period, the created space collapsed and the sinus membrane fell down onto the implant. A small amount of new bone formation occurred in the space created by the collapsed membrane. The average height of newly formed bone around the implants in the sinus was 2.7 +/- 0.7 mm on the buccal side and 0.6 +/- 0.3 mm on the palatal side.ConclusionThe results of this pilot study indicate that blood clots do not have sufficient integrity to enable the sinus membrane to remain in an elevated position for therapeutically effective periods of time. Accordingly, it is recommended that this method be used only when a small aount of new bone formation is necessary around implants in the maxillary sinus cavity.To cite this article:Kim H-R, Choi B-H, Xuan F, Jeong S-M.
