Redraping the inferior orbicularis arc.
The surgical technique of redraping of the inferior arc of the orbicularis oculi muscle is used primarily to produce lower lid and midfacial smoothing in patients undergoing aesthetic surgery. The midfacial fat compartments, suborbicularis oculi fat and malar fat, are bound to the orbicularis muscle by the superficial muscular aponeurotic system so that redraping the orbicularis muscle also repositions the midface. Orbicularis arc redraping should be accompanied by lateral canthoplasty to ensure stability to the shape of the eyelid fissure postoperatively. Modifications in orbicularis redraping and canthoplasty technique are necessary in patients with prominent eyes and distensible lower lids. Supraplacement of canthal fixation is needed in patients with prominent eyes, and lid shortening is needed in patients who have distensible lower lids. This technique also can be used in patients undergoing reconstructive surgery for correction of lower lid retraction because of its ability to recruit periorbital skin upward into the lower lid. For more severe cases of lower lid retraction after aesthetic surgery, adjunctive procedures such as spacer implants in the lower lid and periosteal flap canthoplasty can be used together with the orbicularis arc redraping to rehabilitate patients.
