“…Damage to the osteomeatal complex after endoscopic sinus surgery is also postulated as the causative factor [4]. Conversely, there are instances of relatively acute onset of symptoms occurring after orbital decompression, where it is appropriately described as "imploding antrum syndrome" [5]. The other theory involves hypoplasia.…”

Abstract:The silent sinus syndrome, also known as imploding antrum and chronic maxillary sinus atelectasis, consists of painless enophthalmos, facial asymmetry with inward retraction of the ipsilateral maxillary sinus walls as seen on imaging studies. It is a well-recognized entity in the field of otolaryngology, but the syndrome remains relatively unknown among radiologists despite its characteristic radiological features. The chronic maxillary sinus atelectasis presenting to the Emergency Room with facial trauma, this entity may, to the radiologist unaware of its existence, be misdiagnosed as an orbital floor blowout fracture, especially when the trauma is ipsilateral. Features that distinguish it from the blow-out fracture are the associated deformities of the other maxillary walls, total opacification of the sinus (as opposed to an air-fluid level), and osteolysis of the sinus walls (if present). It can be definitively treated by creating an outlet for mucous drainage from the obstructed sinus, the goal of treatment being to arrest disease progression without development of further deformity. The purpose of this article is to acquaint the reader with the clinical and imaging features of the silent sinus syndrome.

FESS is the way to re-establish the physiological drainage pathway and ventilation of maxillary sinus, usual safe technique to separate the uncinate process from backward is recommended.…”

The Silent Sinus Syndrome (SSS) is a rare condition that causes facial asymmetry, unilateral enophthalmos and diplopia. It is thought to be secondary to chronic maxillary sinus atelectasis (CMA) with reabsorbed bone and subsequent displacement of the orbital floor. Such anatomic modifications occur over time, and therefore it is possible to encounter different stages of the same disease with or without orbital displacement. Clinical findings can be unclear so it makes sense to recognize potentially evolving SSS while other disturbances have to be ruled out. Our purpose is to underline clinical findings for different diagnosis and proper management. We consider Functional Endoscopic Sinus Surgery (FESS) indicated in CMA and SSS to halt the progression of the disease. Nevertheless restitution treatment of enophtalmos due to orbital floor displacement involves plastic reconstruction of the floor of the orbit via transconjunctival approach. We report a case of SSS and discuss distinctive features of non-neoplastic lesions involving the maxillary sinus that should be considered for differential diagnosis.

“…Visus distortion such as vertical diplopia, lagophthalmos and blurred vision occur less frequently. Although there is underlying maxillary sinus ipsilateral atelectasis, specific sinonasal symptoms are absent [4,5]. Etiological theories attempting to explain this phenomenon are numerous.…”

“…The onset of a negative pressure state in the sinus cavity would cause a progressive atelectasis of the air cavity, with a similar mechanism of the middle ear atelectasis secondary to Eustachian tube dysfunction. Furthermore, it would induce a decrease of osteoblastic activity and osteomalacic process of maxillary sinus bony walls and of the orbital floor [4]. The primary mechanism underlying the infundibulum obstruction has not yet been clarified.…”
