[The morphometry of the ear ossicles in humans during development].
The dimensions and the mass of the auditive ossicles was determined bilaterally in 100 human fetuses, of each sex aged from 21 to 40 weeks and 20 individual adults aged 18 to 40 years. It was found that the development of auditive ossicles in human is not completed during fetal life. The analyzed parameters of malleus (a, b, c, d1, d2, e) in the over fetal life period increased adequately by 14.02%, 11.22%, 16.70%, 12.80%, 12.01%, 21.98%, incus by (a, b, c1, c2, d, e) - 7.61%, 11.48%, 11.40%, 23.59%, 12.14%, 14.94%, stapes by (a, b, c, d, e, f) - 6.28%, 7.66%, 8.40%, 4.54%, 4.54%, 4.16%. In the over fetal life period increase of weight of malleus by 22.05%, incus by 26.49%, stapes by 11.57% was also observed. Described parameters of ossicles system are very important with respect to classification to the operations improving hearing in the system convecting of vibration of the tympanic membrane in children.
