Laryngeal cancer is a common malignant tumor of epithelial origin in the head and neck. In 2007, the crude incidence rate of laryngeal cancer in China was 2.04/100,000, accounting for 2.1% of systemic malignant tumors and 13.9% of head and neck tumors, of which about 60% were of vocal type. The incidence rate of laryngeal cancer is 3.54/100,000 in men and 0.49/100,000 in women; the incidence rate of laryngeal cancer is 2.31/100,000 in urban areas and 1.08/100,000 in rural areas. There are many treatment options for early-stage laryngeal cancer, mainly divided into three categories: microlaryngoscopic minimally invasive surgery, radiotherapy, and functional partial laryngectomy. Radiotherapy can obtain basically the same efficacy as surgical treatment for early laryngeal cancer, but many patients cannot complete the treatment due to complications of radiotherapy. Functional partial laryngectomy is an open surgery, which is very traumatic and slow to recover, and the damage to laryngeal vocal function while removing the lesion is more serious than other options. Microlaryngoscopic minimally invasive surgery is now the least invasive surgical treatment for early laryngeal cancer. However, it is worth noting that minimally invasive surgery to preserve laryngeal function requires strict control of surgical indications, and special attention should be paid to the tumor lesions in the weak natural barriers in the larynx (such as the anterior coalition, the paravocalcone space, the hyoid metacarpal space, etc.) before surgery, and once there is a tumor close to or invading the appeal area, it is prone to recurrence after surgery and should be carefully selected. Plasma radiofrequency ablation technology is an electrochemical technology which uses bipolar radiofrequency energy to convert the electrolyte between the cutter head and the tissue into a thin layer of plasma, in which the charged particles are accelerated by electric field to dissociate the molecular chain of the target tissue and achieve the effect of tissue reduction. The plasma RF tip can be performed at a relatively low temperature (40~70℃) with minimal thermal damage to the surrounding tissues, which has certain operational advantages and is another effective means of minimally invasive laryngoscopic treatment for early-stage acoustic laryngeal cancer.
