This retrospective study examined the histomorphometrical outcomes resulting from managing Schneiderian membrane perforation during maxillary sinus floor augmentation using two different approaches and relating the results to perforation size.
19 subjects (7 males, 12 females, mean age 53.3±10.5 years), who experienced a sinus membrane perforation during lateral sinus lift procedure, were enrolled. Perforations were addressed utilizing either the "Sinus Pack" technique (test group, 11 subjects) or collagen membranes with absorbable sutures (control group, 8 subjects). The "Sinus Pack" consisted of a combination of collagenated porcine bone, polyunsaturated fatty acids, and a biocompatible synthetic copolymer, wrapped in a resorbable porcine mesenchymal collagen membrane. Histomorphometry outcomes of both techniques were compared.
The percentage of vital bone was significantly higher with the "Sinus Pack" approach (44.5% ± 19.8%) compared to the control group (26.3% ± 21.2%) (P= 0.045).
The "Sinus Pack" approach for managing sinus membrane perforations appears to be effective and advantageous, as it has resulted in optimal histomorphometric outcomes, indicating a significant increase in vital bone.
本回顾性研究探讨了在使用两种不同方法处理上颌窦底提升过程中发生的筛状膜穿孔时的组织形态计量学结果，并将结果与穿孔大小相关联。
19 名受试者（7 名男性，12 名女性，平均年龄 53.3±10.5 岁）在侧窦提升过程中经历了窦膜穿孔，被纳入研究。穿孔分别采用“窦袋”技术（实验组，11 名受试者）或带可吸收缝线的胶原膜（对照组，8 名受试者）进行处理。“窦袋”由胶原蛋白化猪骨、多不饱和脂肪酸和生物相容的合成共聚物组成，包裹在可吸收的猪间质胶原膜中。比较了两种技术的组织形态计量学结果。
与对照组（26.3%±21.2%）相比，“窦袋”方法的活骨百分比显著更高（44.5%±19.8%）（P=0.045）。
对于处理窦膜穿孔，“窦袋”方法似乎是有效和有利的，因为它产生了最佳的组织形态计量学结果，表明活骨有显著增加。
