Effect of CO2 laser under suspension laryngoscope on patients with vocal cord polyp / 中国内镜杂志

ABSTRACT

Objective To analyze the effect of CO2 laser under suspension laryngoscope on patients with vocal cord polyp. Method 118 patients with vocal cord polyp from November 2013 to August 2015 in our hospital were chose as research subjects, all patients were divided into observation group (n=54) and control group (n=64) accord﹣ing to different treatment. Control group patients received conventional laryngoscope resection; observation grouppatients received CO2 laser under suspension laryngoscope. Then compare the two group patients' voice indexes, a﹣cute phase proteins, rehabilitation and recovery speed after treatment. Results Observation group patients' F0, HNR values were higher than control group patients, PPQ, APQ, NNE values were lower than that in control group (P<0.05);early observation group patients' postoperative serum CRP, α1-AG, CER,β2-MG values were lower than con﹣trol group patients, ALB value was higher than control group patients (P< 0.05); observation group patients' cure rate was higher than control group patients, valid and invalid rates were lower than control group patients, the first sound time, sound full recovery time, discharge time were shorter than control group patients (P< 0.05). Conclusion Vocal cord polyp patients receive laser under suspension laryngoscope treatment, can effectively promote recovery rate, have advantages of minimally invasive and rapid recovery after surgery.
