ABSTRACT

Objective To study the effects of two kinds of vertical partial laryngectomy on laryngeal function,postoperative extubation rate and survival rate of patients with glottic laryngeal carcinoma.Methods From January 2013 to January 2014,one hundred and fifty patients with glottic carcinoma who treated in Huzhou Gospel Hospital were selected.The patients were divided into observation group and control group by random number table method,with 75 cases in each group.The control group used the traditional vertical partial laryngectomy,the observation group was treated with modified vertical partial laryngectomy.The postoperative survival rate,extubation rate,extubation time and complications were observed in the two groups.Results The extubation rate was 100.00% (75/75) in the observation group and 97.33% (73/75) in the control group,the difference was statistically significant between the two groups(χ2 =2.027,P>0.05).The extubation time in the observation group was (11.85 ± 0.49)d,which in the control group was (14.55 ± 0.56) d,the difference was statistically significant between the two groups( t=31.424, P<0.05).There were 67 cases(89.33% ) with grade 0 and 8 cases(10.67% ) with grade 1 in the observation group.The swallowing function of the observation group was stronger than that of the control group( Z=5.238,P<0.05).The 1-year and 2-year survival rates of the two groups were similar(all P>0.05).The 3-year survival rate of the observation group was 97.33% (73/75),which of the control group was only 88.00% (66/75),the differ-ence was statistically significant between the two groups (χ2 =4.807,P<0.05).There was no pharyngeal fistula in both two groups. There were 5 incision infections in the control group, and 1 incision infection in the observation group.There was no statistically significant difference in the incidence rate of complications between the two groups (χ2 =2.778,P>0.05).Conclusion Improved vertical hemilaryngectomy therapy for patients with glottic laryngeal carcinoma can effectively shorten the time of extubation,better preserve swallowing function,improve the long-term survival rate,and the extubation rate and complication rate are similar with the traditional vertical partial laryngectomy.
