[Application of Eustachian tube pressure measurement to observe the function of Eustachian tube after tympanostomy in children with otitis media with effusion].

Objective

To evaluate the feasibility of Eustachian tube pressure measurement after tympanic membrane placement and the timing of postoperative tube removal. Method:A total of 108 patients（202 ears） with chronic otitis media with effusion（OME）were enrolled. All patients underwent tympanostomy（T-tube） or with adenoidectomy. Eustachian tube pressure measurement（TMM） was performed preoperatively and postoperatively, and the Eustachian tube score（ETS-5） was recorded before and 6 and 12 months after surgery and statistical analysis was performed. Result:There was a statistically significant difference between the preoperative ETS-5 scores at 6, 12, and 18 months after surgery. There was no significant difference between the 12 months and 18 months after surgery. There was no significant difference in the recurrence rate of OME in patients with tympanic membrane indwelling time of 12 months and 18 months, but the rate of perforation was 18 months.

Conclusion

The tympanic ventilation tube helps the recovery of the Eustachian tube function. The TMM examination is simple and non-invasive. It is suitable for the evaluation of the timing of the tympanic ventilation tube. The tympanic membrane is suitable for tube removal after 12 months of indwelling.
