Combined Single-Step Procedure for Correction of Silent Sinus Syndrome

Silent sinus syndrome (SSS) is a rare condition characterized by enophthalmos and hypoglobus that is generally not related to trauma or surgery. We present a 30-year-old man who noticed facial asymmetry during the previous month and was referred to our oculoplastic clinic. His examination revealed right hypoglobus and a 2-mm right enophthalmos. The diagnosis of right SSS was confirmed by orbital and paranasal computed tomography scan. The patient had no otolaryngological symptoms and visual acuity was normal bilaterally. He was treated surgically in a combined approach by a team of oculoplastic and otorhinolaryngology surgeons. Functional endoscopic sinus surgery included uncinectomy, maxillary antrostomy, and orbitotomy, with insertion of an orbital implant. This case demonstrates that a single-step surgery for correction of enophthalmos secondary to SSS is a viable option, leading to quick rehabilitation and excellent aesthetic results.
