Background:

  • Conductive hearing loss diagnosis presents challenges with standard audiological methods.
  • Laser Doppler interferometry (LDI) is a novel technique explored for clinical diagnostic applications.

Purpose of the Study:

  • To evaluate the diagnostic value of LDI in a clinical setting.
  • To compare LDI with standard audiometry for the preoperative differential diagnosis of conductive hearing loss.

Main Methods:

  • A prospective trial was conducted comparing LDI to standard audiometry.
  • Intraoperative diagnosis served as the gold standard for comparison.

Main Results:

  • LDI proved applicable and effective in the clinical sphere.
