Correlation analysis between pharyngeal secretion of eustachian tube and secretory otitis media in children
Objective To explore the correlation between pharyngeal secretion of eustachian tube and secretory otitis media in children.Methods 103 children with secretory otitis media diagnosed and treated in our department from January 2021 to March 2023 were divided into the case group and 115 children with vocal nodules diagnosed and treated in the same period were divided into the control group.Electronic nasopharyngoscope was performed in the two groups,and distortion product otoacoustic emissions,acoustic immittance,pure tone audiometry,CT scan of temporal bone was performed in the case group at the same time.To analyze the correlation between the pharyngeal secretion of eustachian tube and the results of various examinations.Results The positive rate of pharyngeal orifice secretion of the eustachian tube in the case group was up to 89.5％,which was significantly higher than the rate of 17.0％in the control group.The proportion of pharyngeal orifice secretion of grade Ⅲ-Ⅳ was significantly higher than that of grade Ⅰ-Ⅱ(p＜0.05).The results of the oropharyngeal secretion of grade Ⅲ-Ⅳ eustachian tubes for the diagnosis of secretory otitis media in children were not statistically different from the results of acoustic conduction resistance diagnosis,and the agreement was good.Conclusion Grade Ⅲ-Ⅳ pharyngeal secretion of eustachian tube may be one of the characteristic manifestations of secretory otitis media in children,and further examination should be carried out to make a definite diagnosis.
