The exact cause of SSS is still unknown, but it is believed to result from chronic negative pressure within the maxillary sinus, leading to progressive inward retraction of the sinus walls and subsequent orbital floor remodeling. </span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="line-height:105%"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:9.0pt"><span style="line-height:105%"><span style="font-family:" verdana=""><span style="color:#2e74b5">Case Presentation:</span></span></span></span></b><span style="font-size:9.0pt"><span style="line-height:105%"><span style="font-family:" verdana=""> This case report describes a 61-year-old male with slight facial asymmetry and nasal septum deviation with a normal range of vision.

Rhinologists and, to a lesser extent, ophthalmologists and dentomaxillofacial radiologists are skilled at diagnosing SSS through CBCT imaging of the paranasal sinuses. However, general radiologists are not often well aware of this syndrome. Increasing awareness among general radiologists is vital for prompt identification and appropriate care.</span></span></span></span></span></span></span><br> &nbsp;</div> Enophthalmos, Maxillary Sinus, Syndrome 68 72 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-2224-1&slc_lang=en&sid=1 Faeze ZareBidoki faeze.zare1772@gmail.com 100319475328460014085 0000000335247399 No Department of Oral and Maxillofacial Radiology, School of Dentistry, Iran University of Medical Sciences, Tehran Iran Sanaz Heidarkhani Tehrani 100319475328460014086 100319475328460014086 No Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran Zahra kiyamehr z.kiamehr@gmail.com 100319475328460014087 100319475328460014087 Yes Department of Pediatric Dentistry, School of Dentistry, Iran University of Medical Sciences, Tehran Iran
