전신 마취후 일과성으로 발생한 양측성 이하선 종창

Parotid gland swelling in association with general anesthesia is an unusual complication. Benign postoperative parotid swelling should be recognized as a noninfectious, self-limiting process occurring immediately after surgery. This enlargement is non-tender, rubbery in consistency, without crepitus, and may be accompanied by variable salivation. The mechanism of the occurrence remains unknown, but two factors most frequently associated with this phenomenon appear to be physical stimulation or manipulation of the airway or coughing and/or straining. We report bilateral parotid gland swelling in a middle-aged man after surgery under general anesthesia.
