Vinegar and hyaluronidase solutions effectively dissolve plugged tympanostomy tubes, outperforming water and antibiotics. Vinegar is recommended due to its safety profile for ear canal use.

Area of Science:

  • Otolaryngology
  • Biomaterials Science

Background:

  • Tympanostomy tubes are crucial for middle ear ventilation.
  • Tube occlusion by middle ear effusion can impede function.
  • Effective methods for clearing plugged tubes are needed.

Purpose of the Study:

  • To identify optimal solvents for dissolving plugged tympanostomy tubes.
  • To compare the efficacy of various solvents, including vinegar, hyaluronidase, and ototopical antibiotics.

Main Methods:

  • An in vitro laboratory study was conducted.
  • 260 fluoroplastic tympanostomy tubes were plugged with dried mucoid middle ear effusion.
  • Twelve solvents, including water and antibiotics, were tested for their ability to clear the tubes.

Main Results:

  • Vinegar and hyaluronidase solutions demonstrated significantly greater efficacy in clearing plugged tympanostomy tubes compared to water (P = .0030).
  • Visual and tympanometric assessments confirmed clearance times.

Conclusions:

  • Vinegar and hyaluronidase solutions are more effective than water and ototopical antibiotics for clearing plugged tympanostomy tubes.
  • Vinegar is the preferred choice due to its established safety for otic applications.
