The imploding antrum or silent sinus syndrome is a rare phenomenon that presents with spontaneous painless enophthalmos and hypoglobus. It occurs due to ipsilateral maxillary antral atelectasis secondary to asymptomatic obstructive chronic sinus mucosal disease. Ophthalmologists, otorhinolaryngologists, and radiologists must be aware of this entity. This article illustrates the typical presentation in a 17-year-old male with unilateral ptosis and a deep superior sulcus, and characteristic imaging findings of ipsilateral increased orbital volume and depression of the orbital floor, maxillary sinus opacification and atelectasis with retraction of the posterolateral and medial walls, lateralization of the uncinate process, and obstruction of the ostiomeatal unit. This is probably the first time that the syndrome is being reported in such a young person. The pathogenesis, differential diagnosis, and treatment modalities of this entity are also reviewed.

“…(a) Silent sinus syndrome, also called imploding antrum syndrome [ 62 ], is a rare disorder characterized by unilateral or bilateral enophthalmos and hypoglobus caused by an alteration of the orbital architecture due to maxillary sinus collapse with chronic hypoventilation [ 62 -64 ]. Its basic pathology involves negative maxillary antral pressure because of obstruction of the ethmoid infundibulum, which generates negative pressure over time [ 65 ].…”

“…CT scans are typical and make the diagnosis definitive [3,4,[8][9][10]. Coronal scans usually show laterally retracted uncinate process and medial sinus wall, enlarged medial meatus, inferiorly displaced orbital floor, increased orbital volume, and axial scans show inward retracted medial and superior walls of the maxillary sinus (MS), decreased MS volume (atelectasis of the maxillary sinus).…”

Introduction. Silent sinus syndrome is a rare condition, characterized by spontaneous and progressive enophthalmos and hypoglobus associated with atelectasis of the maxillary sinus and downward displacement of the orbital floor. Patients with this syndrome present with ophthalmological complaints, without any nasal or sinus symptoms. Silent sinus syndrome has a painless course and slow development. It seems to be a consequence of maxillary sinus hypoventilation due to obstruction of the ostiomeatal unit. The CT scan findings are typical and definitely confirm the diagnosis of silent sinus syndrome. Case report. We present the case of a 35-year-old woman, with no history of orbital trauma or surgery. She had slight righthemifacial pressure with no sinonasal symptoms. The patient had no double vision nor other ophthalmological symptoms. The diagnosis of silent sinus syndrome was based on the gradual onset of enophthalmos and hypoglobus, in the absence of orbital trauma (including surgery) or prior symptoms of sinus disease. On paranasal CT scans there was a complete opacification and atelectasis of the right maxillary sinus with downward bowing of the orbital floor. The patient was treated with functional endoscopic sinus surgery, with no orbital repair. Conclusion. Silent sinus syndrome presents with orbithopaties but is in fact a rhinologic disease, so all ophthalmologists, rhinologists and radiologists should know about it. The treatment of choice for silent sinus syndrome is functional endoscopic sinus surgery, which should be performed with extra care, by an experienced rhinosurgeon.

CT and MRI diagnosis of silent sinus syndrome

Abstract: Both CT and MR imaging enable a diagnosis of SSS to be made, but CT provides a better depiction of all features of SSS necessary for diagnosis and differentiation from other sinus conditions, even in patients without a clinical suspicion of SSS.
