Abstract:
Objective: To evaluate the effect of adrenalin saline local injection on reducing bleeding in endoscopic typeⅠtympanoplasty. Method: A total of 50 patients underwent endoscopic type Ⅰtympanoplasty were prospectively enrolled and were randomly divided into 2 groups. Patients in research group were locally injected 5 ml adrenalin saline with a concentration of 1∶200 000, 15 minutes before operation. And the control group were not injected. Grafts acceptance rates, operation time, blood loss, pre- and pro- operative audiograms were compared between the two groups. Result: Compared with control group, the operative time and blood loss was less in research group. These differences were statistically significant(P<0.05). There was no significant difference in grafts acceptance rate between two groups (P>0.05). After surgery, mean air conduction threshold was increased and the air-bone gaps was decreased in both groups,and no statistical significant deference was found between the two groups(P>0.05). Conclusion: Before endoscopic type I tympanoplasty, adrenalin saline local injection can reduce blood loss significantly. This allows better operative view and experience for surgeons and less surgery damage to patients.
