Silent sinus syndrome (SSS) is a rare idiopathic collapse of the maxillary sinus and orbital floor. We present the second largest series of sixteen patients with SSS and describe their management.
A cohort of 16 patients with spontaneous SSS between 1999 and 2009 were reviewed at the Royal National Throat Nose and Ear Hospital. All patients were initially referred from a postgraduate ophthalmic hospital, Moorfields Hospital.
Fourteen patients required endoscopic sinus surgery to re-establish maxillary sinus drainage and the remaining two settled with intranasal medical therapy consisting of steroids and decongestions. Follow- up ranged from 6 months to 4 years with a mean of 2.6 years. An improvement in enophthalmos and was seen in all surgically treated patients with a mean improvement of 2.2mm and range 0.5-4mm.
SSS arises from congestion of the ostiomeatal complex resulting in negative pressure within the maxillary sinus and a gradual implosion of the antral cavity. Endoscopic sinus surgery successfully re-establishes maxillary aeration in our series and leads to clinical and aesthetic improvement in the degree of enophthalmos and has avoided the need for orbital floor repair in all but two cases.
寂静鼻窦综合征（SSS）是一种罕见的上颌窦和眶底自发性塌陷的特发性疾病。我们报告了第二大系列的 16 例 SSS 患者，并描述了他们的治疗方法。
在皇家国家耳鼻喉医院回顾了 1999 年至 2009 年间 16 例自发性 SSS 患者的队列。所有患者最初均从莫尔菲尔德眼科医院转介而来。
14 例患者需要进行内镜鼻窦手术以重新建立上颌窦引流，其余 2 例患者通过鼻内药物治疗（包括类固醇和减充血剂）得到缓解。随访时间为 6 个月至 4 年，平均为 2.6 年。所有接受手术治疗的患者的眼球内陷均有改善，平均改善 2.2mm，范围为 0.5-4mm。
SSS 是由于筛窦口复合体充血导致上颌窦内负压，并逐渐使窦腔塌陷引起的。在我们的系列研究中，内镜鼻窦手术成功地重新恢复了上颌窦的通气，并导致眼球内陷的程度在临床和美学上得到改善，除了 2 例患者外，均避免了眶底修复的需要。
