How Hump Reduction Rhinoplasty is Performed

Dr. Buonassisi explains the step-by-step surgical process for reducing a dorsal hump — the most commonly requested rhinoplasty change.

About This Video

In this video, Dr. Thomas Buonassisi walks through the surgical steps involved in dorsal hump reduction — one of the most frequently requested changes in rhinoplasty. He explains the anatomy of the osseocartilaginous junction, the difference between a bony hump and a cartilaginous hump, and why the technique used depends on the specific composition of the patient's hump. Dr. Buonassisi also addresses the open roof deformity that results from hump removal and explains how osteotomies are used to close it.

Key Takeaways

A dorsal hump is composed of both bone (upper third) and cartilage (middle third) — the ratio varies by patient.

In preservation rhinoplasty, the hump is lowered by letting down the dorsum rather than excising it, preserving the keystone area.

After hump removal, the nasal bones are left separated (open roof). Osteotomies are required to close this gap.

Over-reduction is the most common cosmetic complication — a small residual hump is preferable to an over-reduced, scooped profile.

Computer imaging at consultation helps set realistic expectations for the degree of reduction achievable.

In Dr. Buonassisi's Words
"The dorsal hump is the most common reason patients come to see me for rhinoplasty. What most people don't realise is that a hump isn't just one thing — it's a combination of bone in the upper third and cartilage in the middle third, and the ratio of those two components varies significantly from patient to patient. That matters because the technique I use depends entirely on what the hump is made of. A purely cartilaginous hump can be addressed with conservative trimming. A bony hump requires an osteotome or a rasp. And in preservation rhinoplasty, I'm not removing the hump at all — I'm lowering the entire dorsal platform to bring the profile down while keeping the keystone area intact. That's a fundamentally different approach, and it produces a different kind of result."
