Is It Actually Masseter Dehiscence? A Jaw Implant Surgeon's Honest Take

If you've seen videos of patients with a visible "double bubble" or shelf-like depression along the jaw after jaw angle implant surgery — you've encountered what the internet calls masseter dehiscence. But is that actually what's happening in most cases? In this video, Dr. Jonathan Zelken, board-certified plastic surgeon in Newport Beach, California, presents a clinical argument that many cases labeled as masseter dehiscence may not be true muscular separation at all — and that this distinction has direct consequences for treatment. Dr. Zelken covers: What masseter dehiscence actually means anatomically Why the surgical literature reports wildly inconsistent incidence rates (some as high as 20–30%) A case from his own practice that challenged the traditional diagnosis His alternative hypothesis: periosteal stretching over a prominent implant edge Why the wrong diagnosis can lead to unnecessary surgery — and a visible external scar A non-surgical first-line strategy using neurotoxin and filler If you're a patient experiencing a contour change after jaw implant surgery, or a surgeon evaluating this complication, this video is for you. 0:00 The "double bubble" you've been seeing online 0:39 What masseter dehiscence actually means 1:50 Why the jaw looks hollow — classical mechanism 2:36 The literature problem: no consistent definition 3:12 Dr. Zelken's own practice: ~100 jaw angle implants 3:47 A patient case that raised concern 4:37 Dynamic examination — what he observed 5:00 The key finding: muscle length didn't shorten 5:38 An alternative hypothesis: periosteal stretching 6:26 Why this distinction changes everything 7:03 On the viral TikTok case (Bray) 7:56 Surgical treatment for true dehiscence — and its risks 8:48 Non-surgical strategy: neurotoxin + filler 9:19 Transparency: what we still don't know 9:57 Bringing it full circle: two different problems, one label 10:56 Subscribe Dr. Jonathan Zelken is a board-certified plastic surgeon specializing in custom facial implants, facelift, and blepharoplasty in Newport Beach, California.
