Abstract: is paper aims to draw attention on the diagnostic of nonorganic hearing loss. It is a common diagnostic
present mostly in children with apparent sudden sensorineural hearing loss and in adults who intentionally or not claim to have
a hearing problem.
Material and methods. Two case-reports of nonorganic hearing loss - an adult male patient who complains of leſt ear
hearing loss aſter a physical aggression – head trauma in the leſt temporal region and an eight years-old boy with school problems
who thought he had a hearing problem. Both patients were sent for audiological evaluation in the ENT Institute. Discrepancy
between pure tone audiometry and speech test determined the audiologist to extend the audiological evaluation with objective
methods – acoustic immitance, otoacoustic emissions and auditory brainstem response.
Results. Objective audiological examination revealed normal hearing in the both ears in both patients.
Conclusions. Uncommon informal behavior as well as discrepancies between different tests should suggest a nonorganic
hearing loss which must be completely evaluated. Electrophysiologic methods are most used nowadays in these patients.
Key Words: nonorganic hearing loss, malingering hearing loss, factitious hearing loss, objective audiology.

N
onorganic hearing loss (NOHL) is a term
used to describe a hearing loss that appears
greater than can be explained by auditory system lesion
and pathophysiology [1] and in which subjective hearing
level is different from objective one. “Nonorganic hearing
loss”, “pseudohypoacusis” or “functional hearing loss” is
equivalent terms [2]. NOHL represents the most frequent
etiology of sudden hearing loss in children [3], even
though this diagnostic is oſten forgot.
In literature [4] there is a recommended
nomenclature with different categories of NOHL based
on the degree of intent (intentional or unintentional) and
type of gain (internal or external) (Table 1).
NOHL in children is most frequently bilateral
and is caused by a psychological / psychiatric problem -
factitious or conversion disorder. In factitious, children
play a sick role, in order to avoid facing school or
collectivities problems. More serious are problems in
conversion disorder, when children truly think they
have a hearing problem as an expression of their poor
