ABSTRACT

Introduction: Development of the human inner ear primordium is a sophisticated process that proceeds rapidly in a short period of time. After numerous processes and developmental stages, the mature organs of hearing and balance are perfected before delivery.

Aim: To trace the development of the normal fetal bony labyrinth at different age of the developing fetus.

Materials and Methods: 30 petrous temporal bones of human fetuses were studied, gestational age ranging from 4 to 7 lunar months. Various parameters of the bony labyrinth in dry fetal temporal bones were recorded.

Conclusion: A new regression equation has been derived to predict CR length from length of cochlea and height of lateral semicircular canal. As fetal cochlear development correlates with the surrounding petrosal morphology, studies concerning the relationship between the petrous bone measurement and genetic predisposition to congenital deafness can be useful in diagnosis of causes of congenital deafness.

Key words: Bony Labyrinth, Dry Fetal Temporal Bones, Fetal Cochlea, Lateral Semicircular Canal.
