Silent sinus syndrome

Silent Sinus Syndrome

Silent sinus syndrome (pronunciation: /ˈsaɪlənt/ /ˈsaɪnəs/ /ˈsɪndroʊm/), also known as imploding antrum syndrome, is a rare medical condition characterized by spontaneous, asymptomatic maxillary sinus collapse and enophthalmos.

Etymology

The term "silent sinus syndrome" is derived from the fact that the condition often presents without the typical sinus symptoms, making it "silent". The term "imploding antrum syndrome" refers to the collapse of the maxillary sinus, or antrum, which is a key feature of the condition.

Symptoms

Patients with silent sinus syndrome may present with facial asymmetry, due to the collapse of the maxillary sinus, and enophthalmos, or the sinking back of the eye into the orbit. However, these symptoms are often subtle and may go unnoticed for a long time.

Causes

The exact cause of silent sinus syndrome is unknown. However, it is believed to be due to an obstruction of the ostium, or opening, of the maxillary sinus, leading to negative pressure within the sinus and subsequent collapse.

Diagnosis

Diagnosis of silent sinus syndrome is typically made through a combination of clinical examination and imaging studies, such as computed tomography (CT) or magnetic resonance imaging (MRI).

Treatment

Treatment for silent sinus syndrome typically involves surgery to correct the sinus obstruction and restore normal sinus function. This may include endoscopic sinus surgery or orbital floor reconstruction.
