随着电子喉镜的普及,下咽和喉部增生性病变得以早期诊断。手术是治疗下咽和喉部增生性病变的主要方法,由于下咽和喉部解剖位置深在,手术视野狭窄,组织血供丰富,操作不当或创伤过大易出现创面严重水肿或出血导致上呼吸道梗阻,危及生命。传统的手术方法创伤较大,术后恢复时间长。喉内镜下低温等离子射频消融微创手术临床已广泛应用,是目前治疗喉局限性疾病的首选方法。一、低温等离子射频消融技术的原理低温等离子射频消融术是低温等离子主机
With the popularity of electronic laryngoscopy, hypopharynx and laryngeal proliferative lesions can be diagnosed early. Surgery is the main method for the treatment of hypopharyngeal and laryngeal hyperplastic lesions. Due to the deep hypopharyngeal and laryngeal anatomy, the surgical field is narrow, the tissue is rich in blood supply, improper operation or excessive trauma is prone to severe wound edema or bleeding Respiratory tract obstruction, life-threatening. Traditional surgical trauma, postoperative recovery time is long. Throat endoscopic low temperature plasma radiofrequency catheter ablation of minimally invasive surgery has been widely used, is the preferred method of treatment of local limitations of the throat. First, the principle of low-temperature plasma radio frequency ablation Cryogenic plasma radio frequency ablation is a low temperature plasma host
