The child has a crestal bulge, the doctor said that surgery is required. The child is so young to go to the operating table to move the “big knife”, can not help but make many parents worried, worried about whether or not to withstand the surgery, the surgery will not cause hydrocephalus? What should they do if their child does not recover well from the surgery? How to feed the child in daily life? This series of questions came. In fact, crestal bulge surgery is like repairing a house, and after the repair, it is quite important to regularly check and assess the stability and function of the house. In particular, crestal bulge can be a lifelong condition that requires lifelong review follow-up and attention. After crestal bulge surgery Be alert for hydrocephalus and crestal fluid leak Cerebral crestal fluid is a colorless, clear liquid that circulates continuously in the spinal canal and brain. This circulatory system forms a cushion of water, like amniotic fluid, that protects the crestal medulla and brain tissue from direct contact between the crestal medulla and brain tissue and the skull during shaking. If there is poor circulation of the crestal fluid, or if too much crestal fluid is produced and too little is absorbed, hydrocephalus can accumulate in the brain. It is very rare for hydrocephalus to develop after cremasteroplasty, but usually it may occur after cervicothoracic cremasteroplasty, or if the child has hydrocephalus, the child’s head may be enlarged by the cremaster fluid and become a “big head doll” if not treated promptly. The child may have a fever after surgery or fat necrosis in the wound. It is important to closely monitor the recovery of the wound after crural bulge surgery. The wound is usually a longitudinal incision and it takes two weeks to recover. If the child cries a lot, which leads to high intra-abdominal pressure and increased skin tension on the back, it may affect the speed of recovery. The medication needs to be changed once in 3 days, 7 days and 14 days after the operation, because the postoperative period usually requires a week of hospitalization, so it is changed twice before discharge, and after discharge, the medication can be changed at the local hospital, and the operation can be done according to the standard of medication change for general surgery. After the child’s surgery, the blood circulation of subcutaneous fat at the wound site is poor, and the blood supply to the sacrococcygeal area is originally low, so it is easy to occur liquefaction and necrosis of subcutaneous fat. At this time, the skin surface will be blackened, blistered, and even the wound will be opened. Accordingly, infection and inflammatory reaction will easily occur, thus making the child always feverish and the wound does not heal easily. If this happens, it will take longer to change the medication, even up to 2 or 3 months. If the recovery is still poor, another surgery is needed to clean the wound. Will my child be able to run and jump after surgery and still need to be reviewed again? Cricothyroid surgery is like repairing a house. After the repair, it is quite important to have regular checkups to assess the stability and function of the house. In particular, crestal bulge can be a lifelong condition that requires lifelong review and attention. However, many times parents feel that once their child is able to control bowel movements and walk and run, there is no need for ongoing attention. In fact, as the child grows, the cremaster changes, and the shape and position of the cremaster also changes. Especially if the child has a combined lipoma, long-term post-operative review and follow-up is necessary because it is impossible to remove 100% of the lipoma. Generally, a review is required three months after surgery, and based on this review, the next review is scheduled. If the recovery is good, the review can be done once at six months and once at one year. Can a child with a bulging crest be vaccinated? Parents are concerned about whether their children with crural effusion can receive vaccines, especially vaccines against neurological diseases such as polio vaccine, rheumatoid vaccine and cremasteric poliomyelitis vaccine. In fact, the suitability of the child for vaccination is indicated in the general immunization pamphlet and is also indicated in the vaccination instructions for each vaccine. Cricothyroid surgery is considered a major surgery, and it is sufficient to adjust the vaccination according to this standard. Overall, vaccines are generally not given within three months of major surgery, and if there are vaccines that are written as contraindicated for lifelong neurological disease, then the child is not a candidate for such vaccines. How will my child sleep and eat after cremasteroplasty? Unlike other surgeries, the surgical wound in a child with a bulging crest is in the back, so the child sleeps on his or her back after surgery. Generally for milder cremasteroplasty, you can sleep on your back for a week after surgery, and after you go home from the hospital, you can alternate different sleeping positions; while for more serious cremasteroplasty, with thin skin at the wound, you have to sleep on your back for about a month after surgery. If you change the position at will, it will cause pressure on the wound, which is not conducive to healing. Some parents see their children sleeping on their stomachs, always feel that they do not know how to hold the child, in fact, you can still hold it vertically, as long as you do not have to touch the wound excessively. When babies and children need to drink milk, they need to adjust the appropriate position for the child to avoid squeezing the wound and also to avoid the child choking or not drinking milk. Especially for breastfed children, it is important for the mother to accommodate the child’s position when breastfeeding.
