Congenital Deafness (Melvin W. LaRue Inc., 1958)
The development of the auditory apparatus in the fetus is illustrated in labeled drawings. Congenital nerve deafness is due to arrested development of the otocyst during the second and third fetal months or to prenatal degeneration of the organ of Corti. Charts show hearing loss and deafness in babies born to mothers who had rubella during the third month of pregnancy. Congenital nerve deafness cannot be corrected medically or surgically.
