Objective:To investigate the occurrence and managements of poor recovery after total endoscopic middle ear surgery. Methods:A total of 302 cases（315 ears） who underwent endoscopic middle ear surgery in our hospital from June 2020 to June 2021 were collected. Follow up by means of endoscopy, pure tone hearing threshold, tympanogram was conducted at 1 month, 3 months, 6 months and 1 year after surgery to analyze the incidence, possible causes, treatment strategies and effects of poor results tympanic membrane healing and hearing recovery. Results:Among 302 patients（315 ears） followed up, there were 28 cases with poor recovery. There were fourteen cases of poor eardrum healing, of which 10 cases achieved healing of eardrum after tympanic membrane patching in the outpatient department, with a success rate of about 71.4%. TM recurrence adhesion occurred in 4 cases after surgeries of cholesteatoma and adhesive otitis media. One case completely recovered after self eustachian tube insufflation, while 2 cases maintained the degree of eardrum subsidence, and one ineffective patient chose resurgical treatment, with an effective rate was 75.0%. Failure in hearing improvement occurred in 8 cases, all of which underwent second surgical exploration, and seven cases were improved after the second surgery, with an effective rate of 87.5%. Among the 8 patients with no improvement or aggravation of hearing loss after surgery, four cases had postoperative B-type or C-type of tympanogram, and the hearing could not improve after self eustachian tube insufflation for secondary surgical exploration. and the hearing improved after the secondary surgery. Incorrect orientation of ossicular prosthesis was accounted for another 2 cases, the hearing was improved after the ossicular orientation adjustment. One patient with lateral healing of TM and failed hearing recovery was corrected by a second operation. One case of tympanosclerosis underwent stapes release surgery, but hearing recovery still failed. One patient had recurrent postoperative cicatricial atresia of external auditory canal, and the patient was reluctant to undergo reoperation. Postoperative delayed facial paralysis occurred in 1 case, and the facial paralysis recovered recovered after conservative treatments. Conclusion:Eardrum patch and eustachian tube autoflation are simple and effective early outpatient treatment for patient with poor recovery. For those who failed with conservative treatments such as eardrum patch or eustachian tube and poor hearing recovery, the second surgical exploration is safe and effective. Regular follow up after endoscopic middle ear surgery is necessary for the managements of poor recovery.

OBJECTIVE To investigate the positive rates and distribution of multiple allergens in children aged 6 to 14 with allergic rhinitis(AR) in the Chaozhou area,and to explore whether health education plays a positive role in these patients. METHODS A random sample of 100 school-age children diagnosed with AR at the outpatient department of Chaozhou Central Hospital from January to May 2024 was selected for allergen testing. Additionally,100 school-age children diagnosed with AR at the outpatient department of Chaozhou Central Hospital from January to May 2024 were surveyed before and after intervention using the same self-made questionnaire,and the effectiveness of the intervention was evaluated. RESULTS Among school-age children with AR in Chaozhou area,the top three positive rates of allergens were house dust mites/dust mites(42％),milk(29％) and egg(23％),and the top three strong positive rates were also house dust mites/dust mites(27％),milk(18％) and egg(17％). After health education,the correct response rate to questions on how to reduce AR attacks increased compared to before the intervention. The overall awareness of AR health knowledge was 31.7％,which significantly increased to 91.4％ after the intervention,with a statistically significant difference. CONCLUSION Understanding the positive rates and distribution of allergens in the Chaozhou area is very important for diagnosing and managing allergic symptoms,which can help physicians and patients better cope with AR. Health education can significantly improve school-age children's understanding of AR,promote the formation of good hygiene habits and lifestyles,and has a positive impact on the prevention and treatment of AR in school-age children.
