Summary
Congenital inner ear malformations are not linked to an increased risk of breech presentation. This study found no significant association between vestibular apparatus abnormalities and delivery malpresentations.
Area of Science:
- Otolaryngology
- Obstetrics
- Genetics
Background:
- Speculation exists regarding a link between immature vestibular systems and breech presentation.
- Congenital inner ear malformations are a diverse group of conditions affecting hearing and balance.
Purpose of the Study:
- To investigate the frequency of breech presentation and malpresentations in infants with congenital inner ear malformations.
- To compare malpresentation rates in affected populations to the general population (2%-3%).
Main Methods:
- Systematic literature review of published studies from 1936 to 2016.
- Searched PubMed/MEDLINE for cases involving specific congenital deafness and vestibular nerve aplasia syndromes.
- Analyzed data for the incidence of breech presentation and transverse lie.
Main Results:
- A total of 122 cases were identified and analyzed.
- The frequency of breech presentation was 1.64%.
- The frequency of transverse lie was 1.64%, totaling 3.28% malpresentations.
Conclusions:
- Congenital malformations of the vestibular apparatus do not appear to increase the risk of breech presentation at delivery.
- The observed malpresentation rate in this cohort is comparable to the general population.

44.8K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

01:16Anatomy of the Ear
10.8K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of...

3.9K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
