BACKGROUND AND OBJECTIVE In an orbital fracture involving diplopia, enophthalmos is a major problem to be corrected because ofsoft tissue swelling and limited incision, which causes inaccurate restoration oforbital anatomy and reestablishing orbital volume. Pre-operative computerized planning combined with intra-operative navigation and endoscopy are used to create the accurate anatomical orbit...

the silent sinus syndrome (sss) involves painless facial asymmetry and enophthalmos, which is theresult of chronic maxillary sinus atelectasis. in most cases, it is diagnosed clinically, however, usingthe characteristic imaging features including maxillary sinus outlet obstruction, sinus opacification,and sinus volume loss caused by inward retraction of the sinus walls. obstruction of the maxil...

PURPOSE Chronic maxillary atelectasis is characterized by unilateral spontaneous enophthalmos and hypoglobus due to increased orbital volume secondary to maxillary sinus inward deformation. Reformation of the sinus architecture and reconstruction of the orbit are key to a successful outcome. Here, we introduce a one-staged surgery that addresses both these goals. PATIENTS AND METHODS We retro...

Introduction: Bilateral silent sinus syndrome (SSS) is a very rare pathology reported only in few papers in literature. Most of the described cases are simultaneous, and only one had a metachronous presentation. The evolutionary phases of the disease have yet to be well demonstrated and a complete radiological evaluation is needed to demonstrate the pathogenetic mechanisms that cause the ...

Silent sinus syndrome (SSS) is a rare condition involving the maxillary sinus, characterized by unilateral collapse of the maxillary sinus and orbital floor, associated with negative antral pressure in the absence of sinus symptoms 1, . It is also known as imploding antrum syndrome and typical radiological findings are ipsilateral depression of the orbital floor and opacification of a collapsed...

Blow out fracture of orbit involves fracture of orbital floor without fracture of infraorbital rim. This injury is common from frontal blow to orbit. Frontal blow to orbit causes increased intraorbital tension causing fracture of floor of the orbit (weak point) with prolapse of orbital content into the maxillary sinus cavity. This causes enophthalmos and diplopia. Infraorbital rim is not involv...

Enophthalmos developed in a 44-year-old woman with history of respiratory infection but not of sinus disease. Sinus roentgenograms and MR revealed opacification of the right maxillary antrum, deviation of the nasal septum to the right, obstruction of the right osteomeatal complex, and diminished volume of the right maxillary sinus.

Silent sinus syndrome (SSS) is an uncommon disease characterised by enophthalmos, caused by ipsilateral maxillary sinus atelectasis. The diagnosis is clinical with radiological confirmation. The treatment has two objectives: to regulate the aeration of the maxillary sinus through achieving normal nasal cavity drainage and to restore the orbital architecture. A case of SSS treated in our hospita...

BMJ Case Reports Published online: 5 December 2012 doi:10.1136/bcr-2012007492 DESCRIPTION A 27-year-old man presented with a chief complaint of right eye enophthalmos. He had no visual symptoms and detailed ophthalmic examination showed a right-sided enophthalmos with hypoglobus, giving a sunken sulcus appearance to the right upper lid. The clinical pi...
