Pneumosinus dilatans

Pneumosinus dilatans is a rare medical condition characterized by the abnormal expansion of the paranasal sinuses without the presence of any mass or fluid. The condition is often associated with frontal sinus but can also affect other sinuses such as ethmoid, sphenoid, and maxillary.

Etiology[edit | edit source]

The exact cause of pneumosinus dilatans is unknown. Some researchers suggest that it may be due to an imbalance in the production and absorption of sinus mucosa secretions. Others believe that it may be related to an abnormality in the development of the sinus ostia.

Clinical Presentation[edit | edit source]

Patients with pneumosinus dilatans often present with symptoms such as headache, facial pain, and nasal congestion. In severe cases, the condition can lead to visual disturbances and proptosis due to the pressure exerted on the surrounding structures.

Diagnosis[edit | edit source]

The diagnosis of pneumosinus dilatans is usually made based on the clinical presentation and imaging studies. CT scan and MRI are commonly used to visualize the sinuses and confirm the diagnosis.

Treatment[edit | edit source]

The treatment of pneumosinus dilatans is primarily surgical. The goal of surgery is to decompress the sinuses and relieve the symptoms. The type of surgery depends on the severity of the condition and the specific sinuses involved.
