Background:Chin position and morphology have impact on facial esthetics.Genioplasty(Osteotomy)and alloplastic chin augmentation which are corrective chin surgeries have their own advantages and disadvantages.There are some controversies regarding the most suitable surgical option.Because of lacking such study in Iran and to determine indications for them we tend to design our study.Matrials & methods:in our interventional study on 30 patients (Female:18 ,Male:12) which are randomly categorized in two group, we perform either of the surgeries.patients with cleft of the lip and palate, Developmental syndromes and cases of severe retrogenia were excluded from our study.Our patients were evaluated at first week, third month and sixth month in post operative period in term of neurosensory deficiet, morbidity, infection and satisfaction.The data were analyzed with Fisher exact test and mann witney test.Results:The mean age for osteotomy and alloplastic method were 25.37 and 31.67 respectively.Morbidity, satisfaction and infection rate for either groups were 33.3%-80%-0(for osteotomy)and 13.3%-86%-6.6%(for alloplastic method)Conclusion:The risk for development of mental nerve paresthesia and infection in alloplastic method was lower and higher(respectively)in regard to osteotomy.Alloplastic chin augmentation is recommended for mild microgenia .Osteotomy is standard of the care for patients with severe and functional chin deficiencies.
