TI  - Changes in otoacoustic emissions in patients with idiopathic sudden deafness.
PG  - 121-35
AB  - Transiently click-evoked (TEOAE), distortion product (DPOAE) and spontaneous 
      otoacoustic emissions (SOAE) were recorded and changes in these tests were 
      studied during the recovery process in 15 cases of idiopathic sudden deafness 
      (ISD). In all these cases the amplitudes of TEOAEs and DPOAEs increased 
      concurrently with the recovery of the hearing threshold. Ears with ISD were not 
      different in their OAE characteristics from ears with other forms of 
      sensorineural hearing loss (SNHL). In 4 of the 15 cases, SOAEs could be detected 
      when hearing had recovered. These results suggest that the function of outer hair 
      cells (OHCs) had deteriorated when the hearing threshold was elevated and that 
      OHC activity recovered as hearing improved to nearly normal levels in ISD cases 
      with good outcome.
