The white membrane can start to fall off in about 3-7 days after tonsil surgery, and it can fall off completely in about 10 days, but the speed of recovery varies from patient to patient, so there is some variability in the time of falling off. After tonsillectomy, a pseudomembrane, which is made of cellulose, begins to form on the wound about 6-12 hours later, providing some protection and hemostasis to the wound. Normally, the white membrane will start to fall off in 3-7 days after the operation, and if it goes well, it will fall off completely in about ten days, which also indicates that the patient’s wound is healing relatively well. If the white membrane becomes gray or dark in the process of wound healing, it means that the wound may be infected. At this time, we should pay attention to strengthen the gargling, and we can use gargling solution with disinfectant and antibacterial effect, such as chlorhexidine gargling solution and compound boric acid solution to gargle as prescribed by the doctor. Or follow the doctor’s prescription systemic application of antibiotic treatment. But this time the white membrane shedding time will also be prolonged, probably need about half a month. So after the operation, we should pay attention to the local wound care, avoid eating hard, spicy and stimulating food, and keep light factors to avoid local wound infection and bleeding and affect the healing of the wound. Once there is any abnormality in the recovery process, you need to actively go to the hospital for consultation.
