The role of genioplasty in the management of craniofacial deformities

The function of a genioplasty is to produce an aesthetically pleasing chin contour and improve facial proportions. The aim of this study was to review the role of osseous genioplasty in the management of patients with cranio facial deformities. 52 patients (24 males and 28 females) treated at the Australian Cranio facial Unit in Adelaide, Australia over a 25-year periodwho required a genioplasty as part of their cranio facial management were reviewed. Patients ranged from 17- 44 years (median: 26 years) and the age at which the patient sunderwent genioplasty was between 9 and 36 years (median:17 years). Pre and 6 months post opcephalograms were compared, showing a mean chin advancement of 7 mm and a mean osseous resorption of 20%. One patient was under-corrected and another had post-operative asymmetry, both requiring repeat genioplasty. No long-term nerve dysfunction was noted. The osseous genioplasty is an effective procedure for correcting the chin deformity often seen in patients with cranio facial abnormalities. It is an easy technique to master and is associated with a low degree of morbidity
