Summary

Brain stem auditory evoked potential (BAEP) testing can diagnose deafness in dogs. Bone-conducted BAEP effectively detects conductive deafness, with optimal placement over the mastoid process.

Area of Science:

  • Veterinary Neurology
  • Auditory Neuroscience
  • Diagnostic Imaging

Background:

  • Brain stem auditory evoked potential (BAEP) testing is crucial for diagnosing sensorineural deafness in dogs.
  • Conductive deafness can confound BAEP results, necessitating methods to differentiate it.

Purpose of the Study:

  • To compare air- and bone-conducted BAEP in dogs.
  • To determine optimal parameters for bone-conducted BAEP to detect conductive deafness.

Main Methods:

  • BAEP was recorded using air- and bone-conducted stimuli in dogs.
  • Bone stimulator placement (mastoid, mandible, zygomatic arch), click polarity (condensation, rarefaction, alternating), and stimulus intensity were varied.
  • Latency-intensity and amplitude-intensity functions were analyzed.

Main Results:

  • Optimal bone stimulator placement was identified as the mastoid process.
  • Condensation polarity clicks yielded preferable responses.
  • Bone-conducted BAEP peak latencies were longer than air-conducted BAEP after latency correction.
  • No significant differences in peak amplitudes or interpeak latencies were observed between modalities.
  • Latency-intensity and amplitude-intensity regressions showed similar trends for both modalities.

Conclusions:

  • Bone-conducted BAEP is a viable method for detecting conductive deafness in dogs.
  • Specific parameters, including mastoid placement and condensation polarity, optimize bone-conducted BAEP.
  • This technique aids in accurate auditory pathway assessment in canine patients.
