It is not uncommon to see young girls with labia minora adhesions in outpatient clinics. Some parents are very nervous when they find their child’s vulva abnormal, thinking that it is atresia of the hymen and developmental deformities, and they ask the doctor to check the child’s uterus and ovaries, and whether the vagina is atresia or not, and even check the chromosomes for fear that the child will be a “stone girl”. I think it is understandable for parents to worry about this, as a doctor should explain clearly to parents, so that their children do not have to do too many tests and suffer unnecessary sins, which can also reduce the parents’ mental pressure and economic burden. Labia minora adhesion is usually found in girls aged 3 months to 3 years old. There are mainly the following reasons: (1) young girls have low levels of estrogen in their bodies, and the epithelium is thin and easily damaged, causing injurious adhesions. (2) Young girls vulva and thighs of the fat pad thick, labia close to each other, long-term hold in the arms, less activity, vulvar inflammation will cause inflammatory adhesions. (3) Poor hygienic habits: using diapers for a long time, wearing nylon tight pants for a long time, which leads to dampness of the vulva. Cleaning the vulva in the wrong way, not in place, the inner lips of the labia minora are not cleaned. Improper wiping method after urination and defecation can lead to germs infection and cause adhesion. This is the main cause. Comparison of labia minora adhesion and hymenal atresiaA child with labia minora adhesion is born with a visible vaginal opening, urethral opening, and secretions; while a child with hymenal atresia is born with a vaginal opening that cannot be seen, and vaginal secretions that cannot flow out can appear like the third picture. If you find that the child’s urine line becomes thin, divergent, forceful urination or scratching the vulva, promptly go to the pediatric gynecology department. If labia minora adhesion is diagnosed, early surgical separation can be done on an outpatient basis to avoid urinary tract infection and urinary retention. Pictures of labia minora adhesion before and after surgery are shown in the first picture, and the vaginal opening can be seen after separation. How to prevent labia minora adhesion? (1) Avoid using diapers for a long time, use wet wipes less, and change them frequently if you want to use them. (2) Avoid wearing nylon tight pants and pantyhose for a long time and try to wear cotton absorbent and breathable underwear. (3) Wipe the vulva correctly, after urination and defecation, use absorbent and unbreakable toilet paper to wipe from front to back. (4) Wash the vulva correctly, push away the fat pads of the labia majora, expose the inner labia minora, and wash the dirt on the inner side. (5) Avoid holding the child for a long time, put the child on the bed and let him/her spread his/her legs apart to reduce the chance of adhesion Children with atresia of the hymen are usually left untreated if there is not much vaginal discharge, and are operated before or at the time of menstruation at puberty.
