Improvement in the augmentation genioplasty via suprahyoid muscle repositioning

The surgical correction of chin deficiency has been accomplished by a variety of surgical procedures. In most instances the surgical augmentation of the chin produces good improvement in chin-lips-nose balance as well as the neck-chin angle. However, in certain patients, the neck-chin angle is not satisfactorily improved with augmentation genioplasty alone, due to an aberrant position of the hyoid bone and its associated suprahyoid muscles. In such instances, one should consider simultaneous suprahyoid muscle repositioning additionally, to improve the neck-chin angle. The indications, surgical technique and a representative case are presented.
