For no symptoms of congenital occult spina bifida do not need treatment, if the small hole appears red and swollen, running water need to go to the hospital to receive treatment. The small hole in the baby’s buttocks and tailbone is caused by embryonic dysplasia. You should pay attention to the cleanliness and hygiene of your baby’s buttocks and tailbone, and don’t touch the hole with your hands to avoid infection. It is best to sterilize under the guidance of a doctor to avoid causing second-degree injuries by handling it yourself. If there is a small hole at the tailbone of the newborn’s buttocks, it is usually a problem of congenital developmental deformity, some of which can be self-healed, and those that can’t are in need of surgical treatment. For asymptomatic occult spina bifida, no treatment is needed. Patients should live a regular life, exercise moderately to enhance their physical fitness, and continue to observe and follow up. It is recommended that children with obvious symptoms of spina bifida should be seen promptly for evaluation of their condition and treatment as prescribed by the doctor.
