A new technique for patulous Eustachian tube treatment

Content We investigated the effectiveness of a soft-tissue bulking agent comparing novel approaches of Eustachian tube (ET) augmentation procedures: transpalatinatal Eustachian tube augmentation in local and general anesthesia versus an augmentation with velotraction under general anesthesia. Group (A) transpalatinatal soft-tissue bulking agent with infltration/augmentation under local anesthesia in a sitting position, group (B) transpalatinatal soft-tissue bulking agent infltration/augmentation under general anesthesia in the fat position or group (C) infltration/transoral augmentation of the ET with velotraction under general anesthesia in a fat position. A total of 50 procedures were executed in 50 patients with unilateral PETD. The necessity to perform a second procedure has analyzed a mean of 6 months postoperatively (range: 6–17 months). Compared to the transpalatinatal augmentation in local anesthesia (group A) (100 %  success rate (SR)), the 6-month failure rate was significantly higher for transpalatinatal augmentation under general anesthesia (group B) (80 %  SR) and velotraction augmentation under general anesthesia (group C) (67 %  SR). Patient cohort with transpalatinatal augmentation under general anesthesia required 20 %  and augmentation with velotraction under general anesthesia in 33 %  revision augmentation procedures reviewed at 6 months follow-up (mean follow-up 11.2 months). The transpalatinatal ET augmentation in local anesthesia achieved a statistically significantly superior results. This improvement may be related to the intraoperative “feedback” by the patients in local anesthesia in the sitting position eliminating the necessity for repeated procedures.
