Pneumoparotitis

Source: Wikipedia, the free encyclopedia.

Pneumoparotitis (also termed pneumosialadenitis[1] wind parotitis,[1] surgical mumps,[2] or anaesthesia mumps),[2] is a rare cause of parotid gland swelling which occurs when air is forced through the parotid (Stensen) duct resulting in inflation of the duct.[3]

Signs and symptoms

The size of the swelling is variable, but it is soft[4] and can occur on one side or both sides.[1] It is typically non tender,[4] although sometimes there may be pain.[1] It usually resolves over minutes to hours, however occasionally this may take days.[1] The condition can be transient or recurrent.[5]

Causes

The condition is caused by raised air pressure in the mouth. [1]

Diagnosis and management

Pneumoparotitis is often misdiagnosed and incorrectly managed.

computed tomography may all show air in the parotid gland and duct.[1]

Management is simply by avoidance of the activity causing raised intraoral pressure which is triggering this rare condition.[1]

Prognosis

Recurrent pneumoparotitis may predispose to sialectasis, recurrent parotitis, and subcutaneous emphysema[5] of the face and neck, and mediastinum, and potentially pneumothorax.[1]

Epidemiology

The condition is rare.

positive pressure ventilation.[2] Apart from these factors, the condition mainly occurs in adolescents, often self-inflicted due to psychological issues.[7][8]
