The authors evaluated the health of the maxillary sinus in a group of 18 patients who had undergone sinus lift surgery for implantation purposes, using computed tomography and endoscopic imaging as a means of diagnosis. The study was performed after a mean interval of 31 months. All sinus lift operations were carried out using the lateral flap technique. The authors evaluated graft characteristics and intraoperative and postoperative complications and compared the results with computed tomography and endoscopic images. Endoscopy of a maxillary sinus that underwent microlaceration of the mucosa during sinus lifting showed a situation compatible with healthy conditions. In cases complicated by macrolaceration, the endoscopic picture was typical of sinusitis, even where clinical conditions of this type were not present. In the absence of intraoperative complications, the endoscopic appearance of sinus mucosa appears to improve when autologous graft material is used.
作者对一组18例因植入目的而接受上颌窦提升术的患者的上颌窦健康状况进行了评估，采用计算机断层扫描和内镜成像作为诊断手段。该研究在平均间隔31个月后进行。所有上颌窦提升手术均采用外侧瓣技术。作者评估了移植物特征以及术中及术后并发症，并将结果与计算机断层扫描和内镜图像进行了比较。对上颌窦提升术中黏膜发生微撕裂的上颌窦进行内镜检查，结果显示情况与健康状况相符。在伴有大撕裂的病例中，内镜图像典型地表现为鼻窦炎，即使不存在此类临床症状。在无术中并发症的情况下，使用自体移植物材料时，鼻窦黏膜的内镜表现似乎有所改善。
