Microgenia is the medical term for an unusually small or deformed chin. [1] The contrasting condition, an enlarged chin, is called "macrogenia". [2][3][4] There are seven different chin deformities: Class II microgenia is the most commonly encountered chin deformity, followed by class II macrogenia. [5]

Microgenia, derived from the Greek words "micro" (small) and "geneion" (chin), describes a condition where the chin is abnormally small or recessed. This anomaly can affect the overall balance and symmetry of the face, often leading to self-esteem issues and functional problems such as difficulties in chewing and speaking.

The terms macrogenia and microgenia also refer to size, macrogenia indicating large chin and microgenia a small one. Abnormal jaw positions occur in all cardinal directions. Prognathism and r etrognathism are deformities characterized by an abnormal anteroposterior position.

Macrogenia and microgenia occur when there is a normal skeletal relationship but the chin, skeletal and soft tissue components, failed to develop in proportion to the skeletal base, resulting in marked protrusive (macrogenia) or retrusive (microgenia) facial profile.

Objective: The authors propose a decision making protocol for correcting chin microgenia based on a revision of 345 treated cases. Methods: A retrospective review of 345 cases of chin microgenia was undertaken to understand the proper …

In our study, we aim to report our experiences and long-term results regarding 3 cases to whom chin augmentation combined with implant and osseous method is applied because of serious chin hypoplasia (microgenia).

Understanding the characteristics of microgenia and choosing a rational method is the prerequisite for a good operative result.
