A novel technique for patulous Eustachian tube augmentation

Area of Science:

• Otolaryngology
• Surgical Innovation
• Medical Device Technology

Background:

• Patulous Eustachian tube dysfunction (PETD) significantly impacts quality of life.
• Current Eustachian tube (ET) augmentation procedures have varying success rates.
• Novel soft-tissue bulking agents offer potential for improved ET function.

Purpose of the Study:

• To compare the effectiveness of transpalatal ET augmentation with a soft-tissue bulking agent under local anesthesia versus general anesthesia.
• To evaluate an alternative ET augmentation using velotraction under general anesthesia.
• To determine the optimal approach for resolving unilateral PETD symptoms without requiring revision surgery.

Main Methods:

• Retrospective clinical chart review of 50 patients with unilateral PETD at a tertiary referral center.
• Three groups: (A) transpalatal augmentation with soft-tissue bulking agent under local anesthesia (sitting position); (B) same procedure under general anesthesia (supine position); (C) ET augmentation with velotraction under general anesthesia (supine position).
• Success defined as resolution of PETD symptoms requiring no additional revision augmentations, analyzed at a mean of 6 months postoperatively.

Main Results:

• Transpalatal ET augmentation in local anesthesia (Group A) achieved a 100% success rate.
• Transpalatal ET augmentation in general anesthesia (Group B) had an 80% success rate, with 20% requiring revision.
• Velotraction augmentation in general anesthesia (Group C) had a 67% success rate, with 33% requiring revision.

Conclusions:

• Transpalatal ET augmentation using a soft-tissue bulking agent in local anesthesia provides statistically superior clinical improvement for PETD.
• The 100% success rate in local anesthesia may be attributed to intraoperative patient feedback in a sitting position.
• This approach effectively resolves PETD symptoms, eliminating the need for repeat procedures.
