Old perineal laceration
Old perineal laceration may be caused by trauma, childbirth, improper sexual activity, anal sphincter relaxation, inflammatory irritation, or other reasons. It is recommended to seek medical attention promptly and follow medical advice to improve the condition through daily care, medication, and other methods. Specific analysis is as follows:

1. Trauma: If the perineum has previously suffered external impact, it may cause local skin damage. If not treated promptly, this could lead to an old (chronic) tear. Patients can, under medical guidance, use povidone-iodine solution for disinfection to prevent infection.
2. Childbirth: During delivery, a large fetus may cause tearing in the perineal area. If not properly managed, this can result in laceration. Pregnant women should reasonably control fetal weight before delivery to avoid macrosomia. Medical staff should properly protect the perineum and perform episiotomy when necessary to reduce the risk of perineal tearing.
3. Improper sexual activity: Excessively vigorous sexual activity, incorrect positions, or insufficient lubrication may cause excessive friction and stretching of the perineal tissues, leading to perineal tearing. If the tear is not properly treated, it may develop into an old laceration. Gentle movements should be observed during intercourse, avoiding overly vigorous actions or inappropriate positions. In cases of inadequate lubrication, appropriate use of lubricants can help reduce tissue injury.
4. Anal sphincter relaxation: A large fetus may easily lead to anal sphincter relaxation during childbirth, resulting in old perineal tears. Patients can perform Kegel exercises to strengthen local muscles and ligaments, improve local blood circulation, and achieve some degree of recovery.
5. Inflammatory irritation: Poor personal hygiene after childbirth may lead to inflammation in the perineal area, accompanied by tearing of the genital skin and mucosa. Under medical guidance, patients can use medications such as amoxicillin capsules, cefuroxime sodium for injection, and mupirocin ointment for treatment.
In daily life, adequate rest and sufficient sleep should be ensured, avoiding staying up late. Light outdoor activities such as walking or calisthenics may be appropriately performed to aid recovery.
