Area of Science:

  • Plastic Surgery
  • Orthognathic Surgery
  • Craniofacial Surgery

Context:

  • The chin is a critical component of facial aesthetics and profile.
  • Morphological anomalies can occur along sagittal, vertical, and transversal axes.
  • Genioplasty is a surgical procedure to correct these chin deformities.

Purpose:

  • To review the anatomical basis of genioplasty.
  • To highlight the diagnostic value of cephalometric analysis for chin anomalies.
  • To describe operative steps for horizontal advancement osteotomy and other genioplasty techniques.

Summary:

  • Genioplasty modifies chin bone position in three planes to correct retrogenius, progenius, vertical discrepancies, or laterogenius.
  • It can be performed independently or with other maxillomandibular osteotomies.
