BACKGROUND Dental extraction is a common operation in oral surgery and is usually accompanied by pain,swelling,and local infection.The application of high-speed air turbines increases the comfort of alveolar surgery and makes it more minimally-invasive.However,high-speed gas can enter the subcutaneous tissue of the face and neck or even the chest and mediastinum,which is a serious iatrogenic complication.CASE SUMMARY We describe two cases of severe subcutaneous and mediastinal emphysema caused by high-speed turbine splitting during dental extraction.The first case involved a 34-year-old man who complained of swelling of the face,mild chest tightness,and chest pain after dental extraction.Computed tomography(CT)scan showed a large amount of gas in the neck,chest wall,and mediastinum.The second case involved a 54-year-old woman who complained of swelling and pain of the neck after dental extraction.CT showed a large amount of gas collected in the neck and mediastinum.Both of them used high-speed turbine splitting during dental extraction.CONCLUSION High-speed turbine splitting during dental extraction may lead to severe subcutaneous and mediastinal emphysema.Dentists should carefully operate to avoid emphysema.If emphysema occurs,CT can be used to improve the diagnosis.The patient should be informed,and the complications dealt with carefully. 展开更多
