Can robust otoacoustic emissions (OAEs) be recorded with patent pressure equalization (PE) tubes (called grommets in the UK)?
Answer
It is possible to record normal disortion product otoacoustic emissions (DPOAEs) for test frequencies about 1000 Hz in patients with patent pressure equalization (PE) tubes (or grommets) assuming the middle ear is also normal. DP amplitude is sometimes decreased for lower test frequencies in these patients. On the other hand, abnormal or absent DPOAEs at all frequencies in a patient with PE tubes generally suggests that either the tubes are not patent or there is residual middle ear pathology. Of course, abnormal DPOAEs might also suggest cochlear (outer hair cell) dysfunction, particularly if the abnormalities are mostly for higher test frequencies.
