目的探讨低温等离子射频消融联合局部注射干扰素治疗成人复发性喉乳头状瘤的疗效。方法使用低温等离子射频消融和肿瘤基底局部注射干扰素治疗成人复发性喉乳头状瘤5例。结果 5例患者均治愈,1例在2个月后失访,其余4例分别随访3个月、5个月、11个月和1年2个月,肿瘤无复发。结论低温等离子射频消融术治疗成人复发性喉乳头状瘤损伤小,出血少,联合肿瘤基底局部注射干扰素可以提高疗效。 Objective To investigate the therapeutic effect of low temperature plasma radio-frequency ablation combined with local injection of interferon on adult recurrent laryngeal papilloma. Methods 5 cases of adult recurrent laryngeal papilloma were treated with radiofrequency ablation of low temperature plasma and local injection of interferon into the basal tumor. Results All 5 patients were cured. One patient was lost after 2 months. The remaining 4 patients were followed up for 3 months, 5 months, 11 months and 1 year and 2 months respectively. No recurrence was found. Conclusion Low-temperature plasma radiofrequency ablation for the treatment of adult recurrent laryngeal papilloma has less injury and less bleeding, and the combination of local injection of interferon and tumor basement can improve the curative effect.
