Effect of the combination of balloon Eustachian tuboplasty and tympanic paracentesis on intractable chronic otitis media with effusion.

Objective: To evaluate the effect of the combination of balloon Eustachian tuboplasty (BET) and tympanic paracentesis (TP) on intractable chronic otitis media with effusion (COME).

Methods: Ninety patients with intractable COME were included and randomly assigned to three groups: BET only (30 patients), BET+paracentesis (30 patients), and paracentesis only (30 patients). Otic endoscopic findings and tympanograms were recorded before the surgery and at the month 1, month 3, and month 6 follow-up evaluations.

Results: Both the BET only and BET+paracentesis groups achieved better outcomes than the paracentesis group. The BET+paracentesis group exhibited better otic endoscopic scores than the BET only group (p<0.05) at 1month post-operation. However, no significant difference was found at month 3 or month 6 post-operation. No significant difference in the tympanograms was observed between these two groups at month 1, month 3, or month 6 post-operation. The otic endoscopic sign scores improved from month 1 to month 6 in the BET only group and from month 1 to month 3 in the BET+paracentesis group. The conversion of type B tympanograms improved from month 1 to month 6 in the BET and BET+paracentesis groups but not in the paracentesis only group.

Conclusions: Our results suggested that the combination of BET and TP was effective for intractable COME and can help shorten the recovery period for middle ear effusion.
