Recurrent pneumoparotid: cause and treatment.
OBJECTIVE
To document the etiology and successful treatment of severe recurrent pneumoparotid.


METHODS
Computed tomography, ductal measurement by probe size, surgical treatment.


RESULTS
We performed a superficial parotidectomy for a 13-year-old with a history of recurrent parotitis. He subsequently developed recurrent pneumoparotid in the contralateral gland with subcutaneous dissection of air into the face, neck, and mediastinum. At surgery, Stensen's ducts were measured and found to be abnormally patent bilaterally compared to standardized norms. Parotid duct ligation, commonly used for sialorrhea, was employed as a novel treatment and was curative.


CONCLUSIONS
Insufflation of air into the parotid duct system can trouble woodwind instrument players, can complicate dental procedures, or can be self-induced. It is generally a benign condition requiring no therapy. Occasionally, pneumoparotid can be recurrent and lead to inflammation and infection of the parotid or subcutaneous emphysema.


CONCLUSIONS
In selected cases of recurrent pneumoparotid, ductal ligation may be curative.
