Abstract Introduction The chin is a reflection of the entire face and, along with the nose, is one of the major determinants of facial profile balance. When it is appropriate in size, shape and position, the chin can enhance the normal harmony and symmetry of the face, even camouflaging less than ideal jaw relationships. Failure to perform a needed genioplasty can jeopardise the end product of many hours of otherwise successful major orthognathic or cosmetic surgery. Genioplasty procedure has been used for many years and has been modified in various ways, despite its original description by Trauner and Obwegeser. Aim To overcome the disadvantages of older techniques such as step deformity, less bone contact and more chances of relapse. Method Type 1—Esthetic genioplasty: A curvilinear horizontal osteotomy can be performed at lower border as posteriorly as possible. After the osteotomy, the detached segment can be moved as per the requirement. Type 2— & Namrata Chourasia [email protected] Sharanbasappa R. Japatti [email protected] Chidambar Y.

Functional genioplasty: A horizontal subapical cut was made through full thickness of the mandible involving the labial and lingual cortex, then vertical cuts were made bicortically and two oblique cuts were made at the end of vertical cuts monocortically. Conclusion This modification has various advantages such as more bone contact, no step deformity, less chance of relapse and also most effective treatment for sleep apnoea patients. Keywords Sagittal osteotomy Mental foramen Esthetic genioplasty Functional genioplasty Sleep apnea
Introduction The chin is vital to the human facial morphology as it contributes to the facial esthetics and harmony both on frontal and lateral views [1]. It is a major determinant of facial profile balance. When too long in the vertical or horizontal planes, the chin can convey, be it desirable or undesirable, masculinity and strength. When deficient, it can convey weakness and feminineness [2]. Ever since genioplasty has been introduced, it has few drawbacks such as step deformity, less bone contact, more chances of relapse and so has undergone many modifications. So we present these two new techniques for genioplasty.

We have performed our modification on mandible. Type (1) technique—esthetic genioplasty: With reference to the position of the mental foramen, a sliding osteotomy can be carried out according to the chosen angle to the bone
