A clinical epidemiological study on congenital ear malformation (CEM)

Conclusion and Significance: Approximately 69.9% of CEM cases were confined to the ear itself, with the highest proportion being inner ear malformation alone. Multiple malformations were predominantly associated with CMMOE. Syndromes related to CEM were relatively rare. Among cases of microtia, 96.3% were classified as CMMOE. These cases were predominantly observed in males, right ear and exhibited characteristics such as grade III microtia, atresia of the outer ear canal, ossicles malformation, and multiple malformations. The multiple malformations frequently included hemifacial microsomia, accessory ear, preauricular fistula, as well as heart and kidney deformities. CMMOE often coexisted with ear infections, cholesteatoma, and complications in the nasal and pharyngeal regions.PMID:38071650 | DOI:10.1080/00016489.2023.2276348
