Abstract :

Objectives: Brainstem auditory evoked potentials (BAEPs) possess well established clinical utility. Head size is an important physiological variable leading to inter–subject variability in the test. However, there are conflicting results from the different studies correlating head size with BAEP parameters. Hence the present study was planned to evaluate the influence of head size on the BAEP parameters in healthy adults. Material and Methods: BAEP was recorded in 150 healthy adults in the age group of 18–67 years (75 males and 75 females). Head size was measured from nasion to inion. Pearson correlation coefficient was used to correlate head size with BAEP parameters. The p–value<0.05 was considered as statistically significant. Results: A statistically significant positive correlation was found between head size and absolute latencies of all waves and the I–V interpeak latency in total participants. In males absolute latencies of wave I, III and V and IPL of wave I–V showed a statistically significant (p<0.05) correlation with head size while in females absolute latencies of waves I, III, V and IPLs I–III and I–V showed statistically highly significant (p<0.001) and IPL of wave III–V showed a significant (p<0.05) correlation with head size. Conclusion: Head size shows a positive correlation with BAEP latencies. Hence head size should be considered as one of the important variables affecting BAEP response.
