## Frequently asked questions

### Does deep plane facelift eliminate jowls?

Deep plane facelift is designed to correct jowls: it releases the mandibular retaining ligament and repositions the buccal and pre-mandibular fat pads with the SMAS as one unit, restoring jawline definition. Ageing continues afterwards, and no head-to-head study we can cite measures whether jowls return sooner after a SMAS facelift than after a deep plane one; which technique lasts longer is still debated (Khoury 2025, PMID 40801931).

### What causes jowls and how are they treated?

Jowls form when the mandibular cutaneous ligament weakens and the overlying buccal and pre-mandibular fat pads descend below the jawline. Deep plane facelift is the most effective surgical correction — releasing the mandibular ligament allows the jowl tissue to be repositioned along its original vector. SMAS-plication and skin-only lifts leave the ligament intact.
