Transnasal lacrimal sac rhinostomy is a mature minimally invasive surgical method, which can be completed under local anesthesia. However, some of the lacrimal ducts are in the bone, which is difficult to immerse in the local anesthesia and has a certain degree of pain, and the patient can also choose general anesthesia for the surgery, which will not leave any scars on the face. During and after the operation, there will be a small amount of bleeding in the nasal cavity, accompanied by eyelid swelling, which is a normal reaction to the operation, patients do not need to be nervous, and generally can be self-healing. However, individual patients may experience more bleeding from the nasal cavity, which can be stopped under the doctor’s symptomatic treatment. Patients with heart disease, high blood pressure and other systemic diseases should be operated at a later stage if their systemic conditions permit.
