RESUMO
OBJECTIVE:To compare therapeutic efficacy and safety of dexamethasone with different administration routes in the treatment of chronic secretory otitis media. METHODS:A total of 150 patients with chronic secretory otitis media were random-ly divided into control group(75 cases)and observation group(75 cases). Control group was given Dexamethasone sodium phos-phate injection 5 mg by auripuncture under endoscope. Observation group was given Dexamethasone sodium phosphate injection 5 mg via eustachian tube under endoscope. Both groups were given relevant medicine every 2 days,for 3 times in total. Clinical effi-cacies of 2 groups were observed as well as bone conduction threshold under 1,2,4,8 kHz,the levels of water channel protein 1 and water channel protein 4,recurrence,the occurrence of tympanic cavity effusion before and after treatment. The occurrence of ADR was recorded. RESULTS:The total response rate of observation group(93.33%)was significantly higher than that of control group(80.00%);recurrence rate and the incidence of tympanic cavity effusion of observation group were significantly lower than those of control group,with statistical significance(P0.05). After treatment, the levels of bone conduction threshold in 2 groups were significantly lower than before;the observation group was significantly lower than the control group. The levels of water channel protein 1 and water channel protein 4 in 2 groups were significantly high-er than before;the observation group was significantly higher than control group,with statistical significance (P0.05). CONCLUSIONS:The administration of dexa-methasone via eustachian tube under endoscope is significantly better than auripuncture in terms of therapeutic efficacy for chronic secretory otitis media,relieving clinical symptom,improving bone conduction threshold,up-regulating water channel protein level, reducing the risk of recurrence and tympanic cavity effusion. The two routes of adimistration have similar safety.
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.
