Craniofacial changes in hemifacial microsomia.

Z Smahel

    Journal of Craniofacial Genetics and Developmental Biology
    |January 1, 1986
    PubMed
    Summary

    Severe unilateral microtia in adult males often leads to hemifacial microsomia, causing facial asymmetry and affecting cranial structures. Despite variability, these defects follow developmental rules, with asymmetry present in most severe cases.

    Area of Science:

    • Craniofacial surgery
    • Plastic surgery
    • Medical imaging

    Background:

    • Unilateral microtia is a congenital condition affecting ear development.
    • Facial asymmetry and its impact on craniofacial structures require detailed investigation.

    Purpose of the Study:

    • To analyze craniofacial morphology in adult males with severe unilateral microtia.
    • To correlate the degree of microtia with facial asymmetry and associated anomalies.

    Main Methods:

    • Cephalometry and X-ray cephalometry were employed.
    • Somatoscopy was used for external facial assessment.
    • Patients were categorized into groups based on asymmetry severity.

    Main Results:

    • Hemifacial microsomia was observed in cases with marked asymmetry, showing reduced anteroposterior and vertical dimensions.
    • Hypoplasia was most severe in the lower face, affecting the mandibular joint and orbit.
    • Non-branchiogenic structures, including the cranial base and neurocranium, were also impacted.
    • Facial profile changes included chin retrusion and bite disorders.

    Conclusions:

    • Severe unilateral microtia can lead to significant craniofacial asymmetry and affect various facial structures.
    • The development of facial defects in microtia follows predictable patterns despite individual variability.
    • Marked asymmetry was noted in 20% of severe microtia cases, while 33% showed no definite asymmetry.
