Description

We report a 42-year-old woman who suffered from left eyelid, cheek and neck swelling after dental extraction of a lower left molar. Angioedema was suspected at the first examination because of marked swelling of her eyelid. However, a crackling and crepitant feeling in the left cheek was palpable, and radiography and computed tomography of her head and neck showed subcutaneous emphysema and pneumomediastinum. We diagnosed this case as subcutaneous emphysema and pneumomediastinum caused by the introduction of air into the soft tissue by an air turbine handpiece during molar extraction. Although cases of subcutaneous emphysema and pneumomediastinum after dental treatment have rarely been reported, the possibility of complications may be higher than expected when using higher-pneumatic-pressure air turbine and air syringe systems. Dermatologists should bear in mind this disease entity, which may occur after dental treatment.Skin Research, 12: 126-130, 2013
