Correction of nail grooves is mainly the treatment of onychomycosis, which needs to be taken into account the severity of the patient’s condition, conservative treatment or surgical treatment. 1. Conservative treatment: If the patient’s localized condition is mild, conservative treatment measures can be taken for the time being. Use iodophor to disinfect and then remove the local embedded nail. Ensuring that the nail grows beyond the sides of the nail groove can prevent recurrence of the nail infection lesion. 2. Surgery: If the localized ingrown nail is serious, the local inflammation is obvious, and the abscess lesion is formed, surgery can be considered. Nail extraction is mainly adopted to extract all or part of the ingrown nail, and then the local abscess cavity is destroyed to remove the internal pus. After surgical treatment, antibiotics such as amoxicillin and cefaclor can be taken in order to treat the infection; and the medication can be changed regularly. The appearance of onychomycosis is closely related to ingrown nails. Due to over-trimming nails and other bad habits, the nails grow into the local soft tissues, inducing the emergence of onychomycosis. Therefore, it is necessary for patients to adjust from their own habits and other aspects of life, pay attention to maintain the nails, reduce the incidence of inguinitis.
