The Evaluation of Eustachian Tube Function and Its Influencing Factors After Snoring Operation in Children

This study aims to evaluate and screen out the factors related to the improvement of eustachian tube function after adenoidectomy and/or tonsillectomy, so as to guide the treatment of children's eustachian tube function before and after operation, and provide the treatment direction and methods for diseases related to eustachian tube dysfunction for people with adenoid hypertrophy and/or tonsil hypertrophy complicated with ETD.

This study aims to analyze the changes of eustachian tube function in children with snoring and eustachian tube dysfunction before and after snoring surgery, and to evaluate and screen out the related factors related to the improvement of eustachian tube function after snoring surgery. The patients who were admitted to hospital and diagnosed as children's snoring complicated with diseases related to eustachian tube dysfunction and planned to undergo surgical treatment for children's snoring should be included, and relevant examinations should be improved, including preoperative nasopharyngoscope, otoscope, acoustic immittance and pure tone audiometry. After snoring operation, he returned to the hospital at 6, 12 and 24 weeks after operation for reexamination of nasopharyngoscope, otoscope, acoustic immittance, pure tone audiometry and TMM. The patients were assessed with ETDQ-7 score, ETS-7 score and VAS score by self-administered questionnaire. The effective risk-related factors were screened out by single factor and multi-factor Logistics regression analysis. To guide the treatment of children's eustachian tube function before and after operation, and to provide the treatment direction and methods for children's snoring diseases complicated with ETD.
