Ingrown nail is a deformity in which the finger (toe) nail is embedded in the lateral nail fold. The causes of ingrown nails are: 1. Genetic factors. Many patients with ingrown nails have a family genetic predisposition. Many people in the family have this kind of deformity. 2, bad nail trimming habits caused by. The distal edge of the toenail on both sides is trimmed too deep and too low, resulting in the lateral nail fold tissue crowded to the toenail, eventually leading to ingrown nails. 3, teenagers, children develop quickly, toe is no longer suitable for the old toe extrusion, also easy to cause ingrown nail. The clinical manifestation of ingrown nail deformity is mainly recurrent nail fungus. Due to the mechanical damage to the local nail fold toe by the stump of the toenail. On top of this, local bacterial infection is combined to form a nail infection. Recurrent episodes are painful. Sometimes there is more localized infectious discharge and the foot odor is more pronounced. This is not a major disease, but it is painful for the patient. Many people who have ingrown nails mostly deal with them on their own or go to public baths to repair them, not getting regular treatment, so they can’t heal. So repeated attacks, so that a small disease into a persistent disease. There are also those who go to the hospital, but the doctors they encounter do not know enough about the disease and use nail removal or partial nail removal treatment. However, the nail that grows back is still an ingrown nail. We have encountered patients who have been treated with nail extraction for 6 times and still have not been cured. The surgical treatment for ingrown toenails is orthopedic ingrown toenail surgery. In simple terms, the nail groove is reconstructed by removing the edge of the toenail, along with part of the nail bed tissue, and completely removing that part of the nail root germ layer. This will completely eradicate the ingrown nail deformity. Prevention 1. Maintain good hygiene habits.
