Abstract:
The silent sinus syndrome is a very infrequent pathology. It is described as an enophthalmos secondary to collapse and opacification of maxillary sinus without presenting sinus or nasal symptoms. Osteomeatal complex obstruction is the triggering physiopathologic factor. The clinical symptoms and imaging findings lead to the diagnosis. The treatment consists in restoring sinus ventilation and, if necessary, correcting the orbital floor. We report a case of a woman who was diagnosed and treated because of this entity in our hospital.

Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism, and...
