Objectives: The causes of sensorineural hearing
loss were assessed in a population of students in a
school for the deaf.
Patients and Methods: Ninety-one students (34 girls,
57 boys; mean age 10.6 years; range 7 to 20 years)
from a school for the deaf were evaluated together with
their their family tree. Otolaryngologic, ophthalmologic,
and systemic physical examinations and audiologic
and radiologic investigations were performed.
Results: Sensorineural hearing loss was of genetic
origin in 32.9% of the students. No etiologic factor
could be determined in 31.9% of the cases. Infectious
diseases (38.3%) and consanguinity (26.3%) were
found as the most common etiologic factors in nongenetic
and genetic sensorineural hearing losses,
Conclusion: Sensorineural hearing losses due to
infectious diseases and consanguineous marriages
are preventable conditions. The incidence of sensorineural
hearing losses will decline if these two
conditions are controlled.
