Patient's question:
Recently, I found out that I have moderate cervical erosion. I would like to know whether drug treatment is more thorough or surgical treatment is more effective. I heard that the recurrence rate is very high. What is the percentage, and how can I avoid recurrence?Doctor's answer:
Hello: There are many treatment methods for cervical erosion, and appropriate choices can be made based on the degree of erosion. The main methods are as follows:（1）Medication: For small erosion areas with superficial inflammation, the following medication methods can be used:
① 10–20% silver nitrate: Applied locally once a week, with 2–4 applications constituting one course.
② Potassium permanganate: Applied locally after menstruation, with a repeat application after 1–2 months. When using these medications, careful operation is required to prevent burns to the surrounding vaginal wall, and sterilization should be noted to prevent reinfection.
（2）Physical therapy: Used for larger erosion areas with deeper inflammation.
① Electrocautery: A special electrocautery device is used to burn the erosion tissue, causing it to necrose and fall off. It must reach a certain depth for effective treatment.
② Cryotherapy: A special rapid freezing device is used to freeze, necrose, and detach the diseased cervical erosion tissue. Liquid nitrogen is commonly used as the cryogen, lowering the temperature of the cryoprobe to -196°C. It is placed on the surface of the cervix to freeze and necrose the erosion tissue, allowing new squamous epithelium to regenerate. One treatment is usually sufficient. Generally, there are no adverse reactions, though some patients may experience mild dizziness or lower abdominal pain.
③ Laser therapy: Carbon dioxide laser treatment devices are commonly used. A special laser treatment head is used to irradiate the erosion tissue, causing it to carbonize, form a scab, and fall off, followed by the growth of new squamous epithelium. One treatment is usually sufficient. There is no special discomfort during the procedure, though some patients may experience bleeding when the scab falls off.
