Abstract：
Silent sinus syndrome is a rare disorder characterized by ipsilateral enophthalmos and hypoglobus following a collapse of the orbital floor, in the presence of asymptomatic long-term maxillary sinusitis. It results in enophthalmos, hypoglobus and deepening of the superior palpebral sulcus. A standardized treatment protocol for this infrequent syndrome has not yet been established. The management includes restoration of maxillary sinus ventilation with functional endoscopic sinus surgery and orbital reconstruction, either concurrently or separately. In this paper, the authors presented two patients successfully treated with patient-specific implants, and intraoperative navigation. These cases highlight the benefit of computer-assisted planning and titanium patient-specific implants in the management of silent sinus syndrome. To the best of our knowledge, this is the first report that described the use of PSI with titanium spacers performed with the aid of intraoperative navigation for SSS treatment. Advantages, drawbacks of this technique and treatment alternatives currently available in the literature were also discussed.
摘要：
无声窦综合征是一种罕见的疾病，其特征是眶底塌陷后的同侧眼球内隐和下眼球，在无症状的长期上颌窦炎的存在。它导致眼球内陷，上睑沟的下眼球和加深。尚未建立针对这种罕见综合征的标准化治疗方案。治疗包括功能性内窥镜鼻窦手术和眼眶重建术恢复上颌窦通气，同时或单独。在本文中,作者介绍了两名成功使用患者特异性植入物治疗的患者，术中导航。这些病例强调了计算机辅助计划和针对患者的钛植入物在治疗无症状窦综合征中的益处。据我们所知,这是首次报道在SSS治疗术中导航的辅助下使用带有钛垫片的PSI.优势,还讨论了该技术的缺点和目前文献中可用的治疗方法。
