Patients with shallow sinus tracts can heal with medication such as penicillin and levofloxacin in about 10, and most sinus tracts heal in about 2 to 4 weeks after surgery, and may take longer in severe cases. Sinus tract refers to a latent blind tube that does not communicate with the body’s cavity organs, usually due to infection and necrosis of the body’s tissues, which are drained out of the body through the body surface, and an opening is formed. It can occur in soft tissue, muscle and even bone, and is often accompanied by localized redness and swelling of the external opening, and foul-smelling discharge. The main treatment modalities include medication, which is more effective for patients with shallow sinus cavities and can heal in about 10 days. For simple sinus tracts with submerged cavities that are not deep, granulation or necrotic tissue and foreign bodies such as threads can be removed by scraping with a spatula under local anesthesia; for sinus tracts in the abdominal wall and sinus tracts in chronic osteomyelitis, surgical excision can be performed to promote healing, which usually takes about 2 to 4 weeks. It is recommended that when a patient develops a sinus tract, he or she should consult a doctor in a timely manner to identify the cause and standardize the treatment under the guidance of the doctor.
