Key Points

  • This research compares the effectiveness of two methods for delivering solutions into the middle-ear cavity.
  • Used a rat model to evaluate two delivery methods.
  • Administered solutions via eardrop and intratympanic injection.
  • Measured the successful delivery of the solution into the middle-ear cavity.
  • Both eardrop method and intratympanic injection delivered solutions effectively.
  • No significant difference in effectiveness between the two methods.

Abstract

In our rat model, the eardrop method achieved solution delivery into the middle-ear cavity as effectively as intratympanic injection.
