RESUMO
OBJECTIVE:To investigate the effects of perioperative application of Eucalyptol,limonene and pinene(ELP)en-teric soft capsules on therapeutic efficacy and prognosis in children after grommet insertion of chronic secretory otitis media. METH-ODS:92 cases(145 ears)of chronic secretory otitis media were divided into 2 groups by random number table method,including 46 cases in observation group(68 ears)and 46 cases in control group(77 ears). Both groups received grommet insertion under gen-eral anesthesia by otomicroscope. Control group was not given any drugs;observation group was given ELP enteric soft capsules 1.2 g,bid,from 3 d before operation to 5 d after operation. Subjective therapeutic efficacy and pure tone audiometry of 2 groups were observed 3 days,5 days,2 weeks,1 month and 3 months after surgery as well as acoustic impedance monitoring in children with tube withdrawal from ear 1 month and 3 months after surgery. RESULTS:The total effective rates of observation group 3 days,5 days,2 weeks,1 month and 3 months after surgery were 72.06%,82.35%,85.29%,89.70%and 95.59%;those of con-trol group were 59.74%,66.23%,80.52%,87.01% and 92.21%,with statistical significance(P<0.05). The pure tone audiome-try score of observation group 3 days,5 days,2 weeks,1 month and 3 months after surgery were significantly lower than those of control group,with statistical significance(P<0.05). Therapeutic effective rates of acoustic impedance monitoring in children with tube withdrawal from ear 1 month and 3 months after surgery were 77.78% and 90.48% in observation group,which were signifi-cantly higher than 61.54% and 81.48% in control group,with statistical significance(P<0.05). CONCLUSIONS:The periopera-tive application of ELP enteric soft capsules can significantly improve function recovery and hearing level in children after grommet insertion of chronic secretory otitis media.
