Whether a patient should be hospitalized for sinus surgery depends on the degree of infection of the local sinus tract and the depth and length of the sinus tract location. If the sinus tract is superficial and small in length and there is no local infection such as redness, swelling, or pain, hospitalization may not be required. The sinus tract can be removed under local anesthesia in an outpatient setting, and the wound can be sutured in one phase to achieve better treatment results. Second, if the patient’s sinus tract location is deeper, such as the sinus tract is located in the perianal area, the local nerve is more sensitive and the sinus tract is accompanied by more purulent secretions. In this case, local anesthesia will be accompanied by obvious pain, which is not tolerated by the patient and requires hospitalization. The complete excision of the sinus tract is performed under combined lumbar and rigid anesthesia, and the wound needs to be filled with iodine spun drainage strips, and one-stage suturing is not possible.
