Study Notes
- Ear development anomalies can occur at any stage of development and can have diverse expressions.
- Middle ear and outer ear anomalies often occur together.
- The auricle develops from six hillocks, mostly from the second branchial arch.
- Developmental anomalies of the ear are often associated with syndromal malformations.
- The external auditory canal forms from the first branchial cleft and canalizes from the medial to lateral side.
- The tympanic membrane develops from three layers and is adult-sized at birth.
- The middle ear cavity develops mainly from the first pharyngeal pouch and partially from the second pouch.
- The ossicles develop from mesenchyme, with the malleus and incus appearing as cartilage in the sixth week.
- Congenital atresia of the external auditory canal can range from mild to severe and is often associated with ear and middle ear developmental anomalies.
- Inner ear developmental anomalies are less related to outer and middle ear anomalies but can occur simultaneously in 10% of cases.
