Abstract:

Objective    To investigate the effectiveness of endotoscopic cleaning combined with superoxide solution on the wound healing after the mastoidotympanectomy. Methods    After the radical mastoidotympanectomy, 30 patients, diagnosed preoperatively as suppurative otitis media, were divided two groups, in which the patients of control group received only local antibiotic therapy, while the patients of  experimental group received the local bath of superoxide solution twice a day for one week. One month later, endotoscopic cleaning was performed monthly to clear the wound with superoxide solution. The treatment lasted for 3 to 6 month. Results    The effectiveness of control and experimental group were 93.33% and 66.67%, respectively. The time to dry the ear were 59.28±15.03 days in the control and 96.25±28.87 days in the experimental group (P<0.05). Conclusion    For radical mastoidotympanectomy, the combination of endotoscopic cleaning and superoxide solution can promote the wound healing.
