Abstract
Silent sinus syndrome (SSS) is characterized by progressive atelectasis of the maxillary sinus with centripetal collapse of sinus walls and consequent enophthalmos and diplopia. Herein we report 2 cases of female patients who showed lack of definition of the medial cortical of the right maxillary sinus and the lateral wall of the nasal fossa as a radiographic finding on their panoramic exam. Skull posterior and anterior radiography showed opacification of the right maxillary sinus. Diagnostic hypotheses were chronic rhinosinusitis and neoplasm in the maxillary sinus. Cone beam CT revealed opacification of the right maxillary sinus, obstruction of the ostiomeatal complex and discreet inferior bowing of the orbit floor. The final diagnosis was SSS, and patients were referred to otorhinolaryngologist consult for evaluation and treatment. These cases highlight the contribution of maxillofacial imaging in the diagnosis of SSS, to contribute to early treatment and potentially avoid ocular changes.
