The difficulty in treating keloid is how to prevent recurrence. The above three methods have their own advantages and disadvantages.
Isotope therapy:
Advantages: the treatment is cheap and painless, and many tertiary hospitals can also carry out such treatment.
Disadvantages: it will leave an irreversible white print and the aesthetic level is seriously insufficient.
Linear accelerator:
Advantages: the price is relatively cheap, usually a few hundred dollars can be done. Widely distributed, basically all the top three hospitals have it.
Disadvantages: the radiation dose is relatively large (completely controlled by the doctor's experience), and there will be a slight blank.
SRT- 100:
Advantages: high accuracy (radiation dose is controlled by computer, without manual work), small radiation dose (because it is aimed at skin), and no blank will be left. After irradiation, slight pigmentation will be left, which will generally fade in about one year and approach normal skin.
Disadvantages: because it is an imported instrument, the price is very high (three or four million). At present, there are only several hospitals in Beijing, Shanghai, Wuhan, Jinan and Chongqing.
