Surgical correction of chin deformities: indications and technique

ABSTRACT

The prominent position of the chin between the head and neck makes of it an essential component of the equilibrium and aesthetic of the face. It has a rather conscious impact on the subject personality and affects his relation with his peers. The horizontal osteotomy in genioplasty is a simple, reliable and rapid technique allowing an accurate three-dimensional repositioning of the chin including advancement, posterior, and transverse displacement, and chin height reduction. Indications of this procedure are variable. It is performed as an isolated cosmetic genioplasty, or as a part of a profiloplasty surgery or surgery for correction of a maxillomandibular dysmorphosis. The authors describe their technique and discuss its benefits and disadvantages with emphasis on patient selection and knowledge of technical details
