Objective: To describe a case of silent sinus syndrome secondary to malignancy and discuss the pertinent clinical findings. Silent Sinus Syndrome (SSS) refers to a rare, asymptomatic condition whereby occlusion of the maxillary sinus ostium results in gradual resorption of air, creation of negative pressure and collapse of the maxillary walls. Methods: Review of medical records and literature review using NCBI/PubMed. Results: We describe a case of a 54-year-old gentleman presenting solely with enophthalmos. He had been diagnosed with stage IVa small lymphocytic lymphoma (SLL) 1.5 years prior to this, which was being managed with active surveillance. CT demonstrated severe bowing of the anterior and posterolateral wall, inferior displacement of the floor of the orbit and right enophthalmos, thus supporting a diagnosis of silent sinus syndrome. Compared to previous staging CT at the time of the lymphoma diagnosis these findings were entirely new, and soft tissue in the pterygomaxillary fissure was found to be enlarged. The patient underwent endoscopic sinus surgery and a right maxillary mega-antrostomy was performed to ventilate the maxillary sinus and prevent progression of eye symptoms. A biopsy was taken from the pterygopalatine fossa, which was confirmed to be chronic lymphocytic leukemia (CLL). Conclusion: This case is unique both in being secondary to malignancy, as well as being rapidly progressive given the presence of radiologically normal appearances 1.5 years prior to presentation. Although a rare condition, prompt recognition of SSS is vital to prevent ophthalmological complications. This report highlights malignancy as a potential cause in cases with focal bony remodeling.

Abstract Aim Silent sinus syndrome is a rare condition characterised by progressive, painless enophthalmos with subsequent development of hypoglobus due to orbital floor resorption. It is caused by hypoplasia of the ipsilateral maxillary sinus due to atelectasis. It may be associated with previous orbital floor surgery or trauma or may be idiopathic. We describe the case of a 33-year-old female treated with a customised orbital floor implant, and a review of the condition from available literature. Method A total of 53 patients with a diagnosis of silent sinus syndrome reported in 7 different papers from 2003-2020 were compared in age, presenting signs and symptoms, radiographic findings and the types of treatment provided. Results The patients ranged from ages 19 to 91, with an average age of 45.1 years, and a male to female split of 29:24. The most common presenting sign was progressive unilateral enophthalmos, usually in the absence of any ocular symptoms. Treatments included endoscopic maxillary antroscopy, orbital floor repair (prefabricated or customised) and septoplasty. Conclusions Silent sinus syndrome typically presents with unilateral enophthalmos which is often painless and not associated with any visual disturbance. It possesses characteristic clinical and radiographic signs. The management of choice is surgical and does not tend to recur in the years immediately following resolving treatment. Since the advent of 3D printing, accurate customised orbital plates can now be designed to correct the hypoglobus which is a major aesthetic component when it presents in this condition.

Background Maxillary sinus hypoplasia (MSH), associated with enophthalmos and hypoglobus in the silent sinus syndrome (SSS), is a poorly studied condition. The real incidence of MSH and SSS in the adult population is not known. Our study aims at estimating the radiological prevalence of MSH and identifying undiagnosed cases of SSS in a retrospective cohort. Methods A cross-sectional retrospective cohort study was performed in adults, without a history of maxillofacial surgery or trauma, undergoing head CT scans. A radiological database of 1012 consecutive scans was reviewed independently by two authors to identify patients with signs of MSH and SSS and associated findings (septal deviation, uncinate deviation, concha bullosa, sinus opacification, bony rarefaction, and pterygopalatine fossa enlargement). The findings of MSH and SSS were compared with radiological reports. Results 891 eligible CT scans were analyzed. MSH and SSS prevalences were 6.17% (n = 55) and 0,56% (n = 5), respectively. The maxillary sinus was normally or partially ventilated in 96.36% of MSH patients. Lateralization of the uncinate process was detected in about 50% of MSH patients, while a septal deviation towards the affected sinus was detected in 21.82%. In 20% of MSH scans, a concha bullosa was identified. Radiological reports identified a single MSH case. Conclusions Our study confirmed the literature data on MSH prevalence, while it determined a precedently unknown prevalence for SSS, underestimated in the radiology reports. This prevalence needs further confirmation but suggests a routine accurate comparison of both maxillary sinuses in CT scans.

Background The histopathology and microbiology associated with silent sinus syndrome (SSS) have not been well described. Objective This study details the histopathological and microbiological characteristics in addition to radiographic findings of SSS in comparison to those of chronic maxillary sinusitis (CRS). Methods 42 patients diagnosed with SSS at Mayo Clinic Hospital in Arizona were identified. Paranasal computed tomography scans of the 42 SSS patients as well as 42 matched CRS patients were analyzed in order to assess differences in the prevalence of septal spurs/deviation. 20 of the SSS patients and 19 of the matched CRS patients also had histopathology and microbiology reports, which were compiled and summarized. Additionally, 19 SSS and 19 matched CRS patients were contacted via phone survey for a more complete patient history regarding maxillary dental disease/surgery. Results SSS patients have a significantly higher prevalence of septal spurs/deviation than CRS patients. The microbiomes of SSS patients more closely resemble those of healthy controls than those of CRS patients. Analysis of the histopathology of SSS reveals chronic, non-specific inflammation similar to that seen in non-eosinophilic CRS without polyps. SSS patients were significantly more likely to have a history of maxillary dental disease requiring surgery. Conclusion These data support the hypothesis that the pathogenesis of SSS is more likely due to anatomical/mechanical factors than inflammatory/microbiological factors.
