Thank you for your query.
Kindly do not panic.Though you have not mentioned the time frame of the problem following surgery the confusion may be due to Versed
and it will get well after its effects wear off.Most children go through a phase of delirium
after surgery so the hearing loss
be be subjective.Wait for 48hrs following surgery and then take an informed decision.Consult an ENT. Hope this answers your query.Have a nice day.
