Abstract

Introduction  : Conductive  Hearing  Loss  (CHL)  often presents with  lateralization of sound   to  the  affected  ear , making  hearing  tests  fundamental  in  clinical settings. Accurate lateralization  of bone  conduction  in both  Audiometric  Weber’s  (AW)  and Tuning fork   Weber’s  (TFW)  tests is  crucial  in diagnosing  the type and  severity  of hearing loss  .

Methods  : In this  observational cross-sectional study  ,80  people  aged 12-67 years with  unilateral  CHL  or bilateral  asymmetrical  CHL  in the ENT  Department  , SLIMS, Puducherry were  enrolled. The TFW  test  was performed  according  to the  established protocol at  256  and   512  Hz.  For the AW  test  , bone vibrator  was  placed in  the  middle of  forehead,  where  250  and  500  Hz  frequencies  were  tested. TF  and  AW test  results  were  compared  with  the   expected  lateralisation  from  the  respective  PTA  results.

Results:  At  256  Hz  , overall  accuracy  values  of  TFW  and  AW  tests  were  81.1%  and   86.5%  respectively . At  512  Hz  the  overall  accuracy  results  of  TFW  and  AW   tests   were  85.1%  and  82.4%  respectively.

Conclusions: Both  AW  and  TFW  tests  were  reasonably  accurate  in  assessing  patients   with  CHL . As  such  it is  recommended  for  audiologists  to  conduct  simple  AW  test  in   conjunction  with  other  audiological  tests  to  verify  PTA  results  as masking  problems  and   questionable  audiograms  are  commonly  encountered  in  clinical practice.
