title: Silent sinus syndrome as a recognised cause of unilateral painless enophthalmos.
abstract: An uncommon case of unilateral painless enophthalmos in a 44-year-old woman is presented. Despite the noticeable orbital asymmetry caused by enophthalmos, the patient has normal visual acuities in both eyes with unremarkable ophthalmic examination. Diagnosis of silent sinus syndrome was confirmed on the CT orbits and paranasal sinuses, showing complete opacification and atelectasis of the maxillary sinus. The patient achieved satisfactory improvements in her nasal symptom and facial appearance following functional endoscopic sinus surgery.
