Pneumoparotitis

Pneumoparotitis is a rare condition characterized by the inflammation of the parotid gland due to the retrograde flow of air through the Stensen's duct. This condition is also known as sialocele or parotid duct diverticulum.

Etiology

The exact cause of pneumoparotitis is not well understood. However, it is believed to be associated with activities that increase intraoral pressure, such as blowing musical instruments, scuba diving, or even excessive yawning. The increased pressure forces air back into the salivary ducts, leading to inflammation and swelling of the parotid gland.

Symptoms

The primary symptom of pneumoparotitis is recurrent swelling of the parotid gland, which is often painful. Other symptoms may include xerostomia (dry mouth), sialorrhea (excessive salivation), and fever. In severe cases, the condition can lead to sialadenitis (inflammation of the salivary gland) or sialolithiasis (formation of stones in the salivary gland).

Diagnosis

Diagnosis of pneumoparotitis is typically made based on the patient's history and physical examination. Imaging studies such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) can be used to confirm the diagnosis and rule out other conditions.

Treatment

Treatment of pneumoparotitis primarily involves managing the symptoms and preventing complications. This may include pain management, hydration, and the use of sialogogues to stimulate saliva production. In severe cases, surgical intervention may be necessary.
