The chin is one of the factors which express human character, and appropriately protruding chin is very important to harmonious profile, the purpose of genioplasty is to reshape the chin and improve the facial esthetics which is one of the purposes of orthodontic treatment. It can be classified as augmentation genioplasty which enlarge the chin vertico-horizontally and reduction genioplasty which smallen it. The examples to apply this procedure are as follows. 1. advancement of retruded chin 2. reduction of chin prominence 3. control of chin vertical dimension 4. correction of asymmetry

Genioplasty may considerably change a person's face which needs surgical correction of deformed chin. Comprehensive treatment planning is therefore decisive for the treatment to be successful. A three-dimensional analysis of chin relative to cranial base, upper and lower jaws using the frontal and lateral facial photographs and cephalographs permits classification of the defective chin position and provides a basis for operation planning and deciding upon the operation method. A chin miniplate system has been developed for intraoperative registration securing the sagittal, vertical and horizontal position of the osteotomized chin and ould reduce the relapse rate.

The form and location of chin is very important factor which determine the facial impression. Genioplasty is getting popular in order to improve the facial impression as facial beauty is considered as improvable factor. Through the geniplasty, chin can be moved to wanted location 3 dimensionally Genioplasty is relative simple but precise diagnosis and accurate surgical technique is very important for accurate and satisfying results. The form and shape of chin itself can be analysized and also must be evalulated in relation to the nose and lip and face. Author introduces the analysis of the chin, various surgical techniques of genioplasty and presents some cases.

The interforaminal region is usually considered as a safe region in the chin bone graft without important vital anatomical structures to be damaged. But the accurate anatomy of the interforaminal region, with its potential clinical relationships, is controversial. Moreover some complications suggesting damage of incisive terminal branches after chin bone harvesting are reported such as sensory discomfort and pain etc. In order to verify incisive innervation of symphyseal area, we examined the cross-sectional CT scan images taken for preoperative planning of implant placement with chin bone graft and some parameters were measured; (1) visuality rating of incisive canal (2) vertical and horizontal diameter of canal (3) distance from lower border of the incisive canal to the lower border of the mandible (4) shortest distance from anterior border of the incisive canal to the anterior border of the mandible. We report the positive outcome that decrease the complications related with the damages of incisive branch during bone harvesting from the chin.

Background: The relationship between the lateral deviation of chin and the upper and middle facial third asymmetry is still controversial. The purpose of this study is to evaluate the correlation of upper and middle facial third asymmetry with lateral deviation of chin using 3-dimensional computed tomography. The study was conducted on patients who underwent orthognathic surgery from January 2016 to August 2017. A total of 40 patients were included in this retrospective study. A spiral scanner was used to obtain the 3-dimensional computed tomography scans. The landmarks were assigned on the reconstructed 3-dimensional images, and their locations were verified on the axial, midsagittal, and coronal slices. The Pearson correlation analysis was performed to evaluate the correlation between chin deviation and difference between the measurements of distances in paired craniofacial structures. Statistical analysis was performed at a significance level of 5%. Results: In mandible, the degree of chin deviation was correlated with the mandibular length and mandibular body length. Mandibular length and mandibular body length are shorter on the deviated-chin side compared to that on the non-deviated side (mandibular length, r = -0.897, p value < 0.001; mandibular body length, r = -0.318, p value = 0.045). In the upper and middle facial thirds, the degree of chin deviation was correlated with the vertical asymmetry of the glenoid fossa and zygonion. Glenoid fossa and zygonion are superior on the deviated-chin side than on the non-deviated side (glenoid fossa, r = 0.317, p value = 0.046; zygonion, r = 0.357, p value = 0.024). Conclusion: Lateral deviation of chin is correlated with upper and middle facial third asymmetry as well as lower facial third asymmetry. As a result, treatment planning in patients with chin deviation should involve a careful evaluation of the asymmetry of the upper and middle facial thirds to ensure complete patient satisfaction.

Purpose: To report the successful results of using chin bone graft and autogenous tooth bone graft material (AutoBT) in alveolar cleft patients. Materials and Methods: Five patients with alveolar cleft defects underwent alveolar bone grafting. Three patients were treated using chin bone graft, and the other two patients underwent AutoBT graft. After implant site development using chin bone graft in the fi rst three cases, endosseous implant restorations were placed. In case #4 and 5, AutoBT graft material was placed to guide the normal eruption of partially impacted maxillary right canine and to the upper docking site after distraction osteogenesis. Result: Successful implant restorations with closure of the oronasal fistula were achieved in alveolar cleft defect reconstruction using either chin bone graft (Case #1, 2, 3) or AutoBT graft material (Case #4, 5). Case #4 showed enlarged follicle of the right maxillary canine, indicating a normal eruption guide pattern. Conclusion: Both chin bone graft and AutoBT graft showed favorable outcomes in reconstructing alveolar cleft defects. Autogenous tooth bone graft opens up the possibility of avoiding harvesting autogenous bone graft with complications and morbidities.
