Objective To compare and analyze the long-term effect of tragal cartilage-perichondrium type Ⅰ tympanoplasty under ear endoscope between dry and wet ear conditions.Methods Ninety patients with chronic suppurative otitis media admitted to our hospital from January 2018 to January 2019 were selected.They were divided into a dry ear group(n=50)and a wet ear group(n=40).Both groups were treated with tragal cartilage-perichondrium type Ⅰ tympanoplasty under ear endoscopy.Postoperative healing of tympanic membrane,occurrence of complications,changes of air permeability and bone air permeability before and after surgery,and recurrence rate were compared between the two groups.Results The healing rate of eardrum in the dry ear group was 98.00％,which was not significantly different from 95.00％in the wet ear group(P＞0.05).The postoperative air permeability was significantly increased while bone air permeability was significantly decreased in both groups.The differences were statistically significant(P＜0.05).After 6 months,1 year and 2 years of surgery,gradual improvement was significant when compared with before surgery(P＜0.05).There was no significant difference between 3 years after surgery and 2 years after surgery(P＞0.05).There were no significant differences in postoperative air permeability and bone air permeability between the two groups(P＞0.05).There was no sta-tistically significant difference in the postoperative complications and recurrence rates between the two groups(P＞0.05).Conclusions The tympanoplasty under ear endoscope between dry ear and wet ear can effectively repair the tympanic membrane without obvious complications.The long-term hearing effect is stable and the recurrence rate is low in both cases.
