80 Possible Causes for Atretic Ear Canals

  • Rapp-Hodgkin Syndrome

    Rapp-Hodgkin syndrome (RHS) and Hay-Wells [also known as ankyloblepharon-ectodermal defects-cleft lip/palate (AEC)] syndrome have been designated as distinct ectodermal dysplasia syndromes despite both disorders having overlapping clinical features and the same mutated gene, TP63. To search for TP63 mutations in[…][ncbi.nlm.nih.gov]

  • Ring Chromosome 18

    Affected individuals may also have low-set, malformed (dysplastic) ears and/or narrow (stenotic) or absent (atretic) ear canals, with associated hearing impairment.[rarediseases.org]

  • Chudley-Rozdilsky Syndrome

    Facial anomalies may include microcephaly, thickening of the skull, hemifacial microsomia, enlarged frontal sinuses, microtia, atretic ear canal, hypertelorism, blepharoptosis[accessanesthesiology.mhmedical.com]

  • Congenital Aural Atresia

    Microtia-anotia Definition: Deformed or absent pinna with an atretic ear canal. Most forms are associated with conductive hearing loss.[sonoworld.com] Type C (total) atresia includes all cases with a totally atretic ear canal, but a well-pneumatized tympanic cavity.[entokey.com] The external auditory canal may be completely absent or incompletely atretic with further narrowing contributed to by soft tissue bands.[radiopaedia.org]

  • Ring Chromosome 1

    Affected individuals may also have low-set, malformed (dysplastic) ears and/or narrow (stenotic) or absent (atretic) ear canals, with associated hearing impairment.[rarediseases.org]

  • Nager Syndrome

    Seven patients evaluated in this study had histories of early respiratory and feeding problems, micrognathia and absent velum, atretic ear canals and conductive hearing loss[ncbi.nlm.nih.gov]

The external auditory canals may be atretic.[emedicine.medscape.com] Otolaryngologic manifestations The auricular malformations include preauricular pits, which are blind pinhead-sized depressions in the superior part of the pinna of the ear[emedicine.medscape.com]
