Overview

Retrospective analysis reveals significant improvements in clinical outcomes for patients with Eustachian tube dysfunction, suggesting effective intervention strategies.

Key Points

  • Mean sound pressure levels increased significantly from 99.0 dB HL preoperatively to 119.4 dB HL postoperatively (P < 0.05), indicating improved auditory function.
  • Efficacy was observed in 84.2% of cases (16/19 ears), demonstrating significant potential for this intervention for patulous Eustachian tube.
  • Endoscopic-assisted placement of the plug in challenging cases with peritubal cells was successful, highlighting the importance of imaging and technique.
  • Patients experienced a reduction in PHI-10 scores from 26.2 to 7.5 points, indicating marked improvement in symptoms related to Eustachian tube dysfunction.
