Is there a correlation between the clinical findings and the radiological findings in chronic maxillary sinus...

Silent sinus syndrome (SSS) is a clinical syndrome that occurs as a result of chronic maxillary sinus atelectasis (CMA) and is seen with progressive enophthalmos and hypoglobus. The aim of this study was to investigate the correlation between radiological findings and clinical findings in patients with radiologically asymmetrical reduced maxillary sinus volume.

A comparison was made of patients with CMA through evaluation of paranasal sinus computed tomography, magnetic resonance imaging examination of maxillary sinus volume of the CMA side and the contralateral side, thickness of the retroantral fat tissue, infraorbital bone curve, uncinate process lateralisation measurement, middle concha diameter, and calculation of the change in location of the inferior rectus muscle.

The study included 16 patients. Although a statistically significant difference was determined between the healthy and the pathological sides in respect to maxillary sinus volume, thickness of the retroantral fat tissue, infraorbital bone curve, uncinate process lateralisation measurement, and middle concha diameter (p = 0.00, p = 0.002, p = 0.020, p = 0.020, p = 0.007), no significant difference was determined in respect to the change in location of the inferior rectus muscle (p = 0.154). A positive correlation was determined between the increase in sulcus depth and maxillary sinus volume and inferior orbital bone curve (p < 0.05).

In CMA patients suspected of having SSS, radiological maxillary sinus volume analysis, determination of retroantral fat thickness, measurement of the infraorbital bone curve, and measurement of the uncinate process lateralisation can be used as objective tests. However, it should be kept in mind that radiological findings may not always be compatible with the ophthalmological examination findings.
