There is only one enlarged lymph node in the neck, and the removal surgery takes half an hour to 2 hours, which is mainly related to the benign or malignant nature of the lesion, its relationship with the surrounding tissues and the surgeon’s own surgical proficiency. If the lymph node is purely benign, it will take half an hour to remove most of the lymph nodes; if the lesion is malignant and requires lymph node dissection, it will take 1 to 2 hours; if the lymph node is closely related to the surrounding tissues, or even adhered, the operation time will be prolonged; and the higher the surgeon’s proficiency in the operation, the shorter the time will be. After the surgical treatment of cervical lymph nodes, we should observe the condition of the operation area, once there is bleeding in the operation area or infection in the surrounding area, we need to consult a doctor in time and carry out standardized treatment under the guidance of clinicians. Be sure to go to the regular hospital, under the guidance of clinicians for standardized treatment.
