How many women are suffering from itchy vulva? How many patients are seeking for medical treatment but cannot get effective treatment? When you go to the clinic, you can only hear the doctor say, “You have vulvar leukoplakia, there is no good treatment at present” and return home disappointed. What exactly is this disease? It is a vulvar squamous epithelial cell hyperplasia and vulvar sclerosing lichen planus, because the skin is mostly white, so it is also called vulvar white lesion, we commonly call vulvar leukoplakia. Patients often scratch because of itching. As a result of scratching, there are many scratches, redness and swelling in vulva, and there is a result of long-term itching, which makes local ulceration, chancre, ulceration and secondary infection; in atrophic vulva, mild atrophy is seen, and in serious cases, clitoris, labia majora and labia minora atrophy and adhesion, labia minora partially or completely disappeared, posterior joint shrinkage, narrow vaginal opening, elasticity disappeared, and even affect urination and sexual life, and its malignant rate can be up to 1-5%. Patients suffer a lot, but there is no way to seek medical help, do surgery? Surgical treatment is traumatic, the scar is obvious, and the recurrence rate can be as high as 50%; seek Chinese medicine? Chinese medicine treatment methods are complicated, the course of treatment is too long, the patient is not easy to adhere to, and the efficacy is not exact. What to do? In recent years, the birth of high-intensity focused ultrasound treatment has brought light to patients with vulvar leukoplakia. Focused ultrasound is the penetration of the ultrasound beam through the body such as a pre-selected depth within the tissue, producing a biological focal field there without damaging the superficial tissue and adjacent tissue through which the ultrasound passes. In the treatment of vulvar intraepithelial non-neoplastic lesions, the focal area of ultrasound is located in the dermis, causing degeneration of the tissues in the dermis, including blood vessels and nerve endings, and then promoting the formation of new microvessels and improving the nutritional status of the nerve endings to achieve the treatment goal. Advantages: simple method, short course of treatment (most of them only need one treatment), good safety, less pain, high efficacy. Indications:1. Vulvar itching with or without vulvar burning pain and sexual difficulties; 2. Gynecological examination reveals different degrees of white changes in vulvar skin and/or mucous membrane with or without skin roughness, hypertrophy or atrophy, adhesions, vaginal opening narrowing, etc. Tissue biopsy of vulvar whitening area, pathological diagnosis of vulvar dystrophy, which includes three pathological types of vulvar squamous cell hyperplasia, sclerosing lichen planus, and non-specific vulvitis. Contraindications: 1. Exclusion of malignant changes; 2. No skin breakdown; 3. Combined with various acute vaginitis, or not suitable for ultrasound treatment during menstruation, pregnancy or lactation. Minimally invasive treatment with ultrasound focusing system, no side effects, no trauma changes the defects of traditional surgery with great damage, pain, bleeding and slow recovery. 1, the skin of lesion area is intact after treatment, no trauma, no pain; 2, no scar formation after treatment, no vulva deformation, vaginal opening narrowing; 3, short course of treatment, few times (usually only one-time irradiation), greatly facilitate the patients; 4, ultrasound dose and The method is easy to grasp, safe and reliable, and no damage to the surrounding tissues.
