Abstract:
Objective To compare the clinical effects of invasive and non-invasive therapy in treatment of otitis media with effusion. Methods Seventy-six patients (94 ears) with otitis media with effusion were divided into two groups by random digits table. The invasive group (38 cases, 48 ears) was treated by oto-endoscopic myringotomy and grommet insertion and chymotrypsin with dexamethasone washing for 1-2 times; and the non-invasive group (38 cases, 46 ears) was treated by eustachian tube blowing under nasal endoscopy and injecting chymotrypsin and dexamethasone for 1-2 times. The clinical effects between the two groups were compared. Results The patients were followed up for 6-12 months. The total effective rate was 95.8%(46/48) in the invasive group and 93.5%(43/46) in the non-invasive group, the difference was not statistically significant (P ＞ 0.05 ). The ear pressure chart recovery time was (37.5 ± 5.9) d in the invasive group and (38.6 ± 6.1 ) d in the non-invasive group, the difference was not statistically significant (P ＞ 0.05 ). The pure tone audiometry hearing improved ( 20.4 ± 2.7 ) dB in the invasive group and ( 19.9 ±2.5) dB in the non-invasive group, the difference was not statistically significant (P ＞ 0.05 ). Conclusion Both of invasive and non-invasive therapy in treatment of otitis media with effusion have good results, the doctors should choose the appropriate solution according to the patients' condition.
