Patient's question:
The doctor told me to use medication to control cervical erosion and wait until after childbirth to undergo physical therapy. So, should I keep taking the medication continuously and not stop until before the physical therapy?First follow-up question: Then, should I not have sexual activity?
Doctor's answer:
The treatment of cervical erosion mainly includes the following methods:(1) Medication Therapy: For small erosion areas with superficial inflammatory infiltration, the following medication methods can be used:
① 10–20% silver nitrate: Apply locally once a week, with 2–4 applications constituting one course.
② Potassium permanganate: Apply locally after menstruation, followed by a repeat application after 1–2 months. When using these medications, handle with caution to prevent burns to the surrounding vaginal wall. Additionally, ensure sterilization during application to prevent reinfection.
(2) Physical Therapy: Used for larger erosion areas with deeper inflammatory infiltration.
① Electrocautery: Use a specialized electrocautery device to burn the erosion tissue, causing it to necrose and fall off. The treatment should reach a certain depth for optimal results.
② Cryotherapy: Use a specialized rapid-freezing device to freeze and necrose the diseased tissue of the erosion area, causing it to fall off. Liquid nitrogen is commonly used as the cryogen, with the cryoprobe temperature reaching -196°C. Apply it to the surface of the cervix to freeze and necrose the erosion tissue, allowing new squamous epithelium to regenerate. One session is typically sufficient for cure. Generally, there are no adverse reactions, though some patients may experience mild dizziness or lower abdominal pain.
③ Laser Therapy: Most commonly uses a carbon dioxide laser device. Apply the specialized laser treatment head to the erosion tissue, causing it to carbonize, form a scab, and fall off, followed by the regeneration of new squamous epithelium. One session is usually sufficient for cure. No special discomfort is experienced during the procedure, though some patients may bleed when the scab falls off.
④ KS Instrument Therapy: Utilizes special wavelength photothermal treatment, which is painless and highly effective. During treatment with these methods, maintain cleanliness of the external genitalia, and avoid sexual activity, vaginal douching, or sitz baths. Regular follow-up examinations should also be conducted to monitor the healing of the erosion area.
