The pneumoparotid is a rare parotid gland disease that occurs by the entrance of air through the parotid duct. It is thought to be caused by increased intraoral pressure. It can occur as a occupational hazard in wind instrument players or glass blowers , but cases of patients with psychotic problems seeking secondary gain have been reported , and it is sometimes self-induced. Chronic and recurrent cases may be accompanied by complications, such as parotitis, subcutaneous emphysema, pneumomediastinum, and pneumothorax and surgical treatment may be needed. In self-induced cases, behavior modification and conservative management is indicated. In this study, the authors report about a 20-year-old man who had the pneumoparotid caused by habitually inflating his cheeks. (J Clinical Otolaryngol 2009;20:272-276)
