OBJECTIVE: Through clinical observation of @entity738 after CO    laser cordectomy under suspensive laryngoscope to discuss the effects of laryngopharyngeal reflux(LPR) to @entity130 . METHODS: According to the classification of depth and range of CO    laser cordectomy, 111 cases were divided into 5 groups, and the incidence of postoperative @entity738 of each group was observed. The largest number of the 5 groups was 49 cases of type III CO    laser cordectomy which was subdivided into 4 groups according to whether or not laryngopharyngeal reflux and whether or not proton pump inhibitor (PPI) treatment. RESULTS: In 111 cases, 56 cases (50.5%) developed @entity738 after CO    laser cordectomy. The incidence of @entity130 after surgery was 10% (1/10), 26.1% (6/23), 53.1% (26/49), 78.6% (11/14), 80.0% (12/15) in I, II, III, IV, V type, respectively. It had statistical significance in chi-square test between 5 kinds of operative classification and the incidences of postoperative @entity738 (     = 20.32, P < 0.01) and Spearman correlation analysis showed positive correlation between classification of operation and incidences of @entity738 (r = 0.44, P < 0.01). According to LPR (-), LPR (+)and PPI (+), PPI (-), the incidence of @entity738 had statistical significance in these 4 group @entity1 of 49 type III cases (    = 5.83, P < 0.05). The incidence of @entity738 after surgery was the lowest in LPR (-) PPI (+) group (30%) and the highest in LPR (+) PPI (-) group (80%), and it showed significant difference (     = 6.25, P < 0.05). CONCLUSIONS: With the @entity101 and the range after CO    laser cordectomy, it appears rising trend in incidence of @entity738 . @entity8823 and PPI therapy on the incidence of @entity130 has certain influence.
