Background: Tympanostomy tube insertion (TTI) is one of the primary treatments for Otitis media with effusion (OME) in children, a common condition in children. However, there is still no conclusion on the better choice of tube position, and no relevant research has been found in the literature. This study analyzed the results of the two commonly selected tube insert positions, anteroinferior quadrant (AQ) and posteroinferior quadrant (PQ), in order to determine which is the better choice.
Methods: Children with bilateral OME who received TTI in Beijing Tongren Hospital from May 2020 to January 2021 were selected as subjects. one side on AQ and the other side on PQ randomly. Follow-up visits were arranged at 1 week, 1 month, 6 months and 12 months after surgery. The results of audiology and the tube status of the two positions were recorded and compared statistically.
Results: A total of 90 patients with bilateral OME were selected. There was no difference in preoperative hearing between the 2 groups. The AQ group's average air conduction threshold was significantly higher than that of the PQ group 1 week after surgery. Although there was no significant difference in tube fall-off rate between the two groups within 6 months, it was significantly higher in AQ group than that in PQ group at 12 months after surgery.
Conclusions: Compared to TTI on AQ, TTI on PQ is more stable and better improves hearing, and the operation is also more convenient for surgeons. This study provides reference for a better position of TTI in OME therapy.
