Introduction:
Silent sinus syndrome (SSS) is a rare disorder of the maxillary sinus, which may present with orbital symptoms. Most reports of silent sinus syndrome are limited to small series or case reports. This systematic review comprehensively characterizes the various clinical presentations, management, treatment, and outcomes in patients with SSS.
Methods:
A systematic literature search of the PubMed, Cochrane, Web of Science, and Scopus databases. Inclusion criteria were studies describing the presentation, management, or treatment of SSS or chronic maxillary atelectasis.
Results:
One hundred fifty-three articles were included in the final review (n=558 patients). Mean age at diagnosis was 38.8 +- 14.1 years, with a relatively even distribution among sexes. Enophthalmos and/or hypoglobus were the most frequent symptoms, along with diplopia, headache, or facial pressure/pain. Most patients (87%) underwent functional endoscopic sinus surgery (FESS), and 23.5% received orbital floor reconstruction. Post-treatment, patients had significant reductions in enophthalmos (2.67 +- 1.39 vs. 0.33 +- 0.75 mm) and hypoglobus (2.22 +- 1.43 vs. 0.23 +- 0.62 mm). Most patients (83.2%) achieved partial or total resolution of clinical symptoms.
Conclusions:
SSS has a variable clinical presentation, with enophthalmos and hypoglobus being most common. FESS with or without orbital reconstruction are effective treatments to address the underlying pathology and structural deficits.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
