microgenia
Pronunciation: MY-crow-JEE-nee-ah
Underdevelopment of the chin characterized by a receding or weak mandible profile requiring surgical correction.
Full Definition
Microgenia refers to a congenital or developmental condition where the chin appears underdeveloped, receded, or weak due to mandibular deficiency. This condition affects facial harmony and profile aesthetics, often requiring genioplasty or chin implant placement for correction. The condition can be isolated or part of broader craniofacial syndromes. Diagnosis involves clinical assessment and cephalometric analysis to determine the degree of chin projection relative to facial proportions. Surgical correction aims to establish proper facial balance and improve both aesthetic appearance and potential functional issues related to dental occlusion.
Usage
Usage note: Often confused with micrognathia (jaw underdevelopment) and retrognathia (jaw positioned posteriorly).
