To introduce a novel incision design for large advancement genioplasty.

Our variation extends from the premolar to the premolar, maintaining a 5 mm distance from the root apices and the vestibular sulcus. The incision is V-shaped, with the tip aimed at the midline mento-labial sulcus. A sharp beak haemostat is used to dissect the mental nerve between the mucosa and submucosa at the canine region-premolar region. Tunnelling is done to free the nerve at its insertion into the muscle.

This technique offers excellent healing and large advancement genoplasties can be carried out with ease. Amongst all the cases which were performed, none of them showed any incidence of chin ptosis. There was no incidence of hypertrophic scarring noted.
