Hidden hair sinus surgery usually takes about a week to heal. The exact healing time depends on the condition of the hair-hiding sinus, the size of the sinus tract or cyst, the depth of the hair-hiding sinus, and the surgical procedure. Hair-hiding sinus is a skin inclusion that occurs in the sacrococcygeal sinus tract or cyst containing hair, due to residual medullary canal or developmental malformation of the sacrococcygeal suture. There are various surgical methods for hidden hair sinus, such as excision with one-stage suture, surgical excision of all diseased tissue and free muscle, and complete skin closure of the wound to allow one-stage healing. Excision partial suture, excision of diseased tissue, skin on both sides of the wound and sacrococcygeal fascia suture, so that most of the wound healed in one stage, and the middle part of the wound has granulation tissue healing. Excision wound open sub-stage suture, excision wound open is used in cases where the wound is too large to be sutured or in cases of surgical recurrence. Pocket suture, excision of the surface portion of the sinus wall and the skin overlying it, and closure of the wound with gutta-percha or absorbable synthetic sutures to promote healing. Stitches are usually removed in about a week for one-stage healing wounds. Infected wounds, on the other hand, require wound incision and drainage, dressing changes, etc. The healing time depends on the condition. Surgery is the main treatment method, but it is contraindicated when there is inflammation, and should be waited until the inflammation subsides. After surgery, pay attention to maintain good local hygiene, avoid local extrusion and friction and pollution, go to the hospital on time to change the medicine.
