The push-down technique is part of the family of preservation rhinoplasty methods and is used to correct a dorsal nasal hump while maintaining the integrity of the nasal dorsum. Unlike traditional hump resection, which involves excising the bony and cartilaginous hump, the push-down technique lowers the entire nasal dorsum as a single unit.
What Is the Push-Down Technique?
In this technique, the dorsal hump is “pushed down” by removing subdorsal cartilage and bone (usually part of the septum and ethmoid bone), allowing the dorsum to descend in one piece without being cut from above. The entire nasal vault, including the bridge, remains intact and descends as a unit.

Advantages of the Push-Down Technique:
1. Preservation of Natural Dorsal Aesthetics
- Maintains the native dorsal lines and anatomical continuity, resulting in a more natural-looking nose.
2. Avoids Open Roof Deformity
- Since the dorsum is not resected, there is no need to reconstruct the mid-vault with spreader grafts or flaps.
3. Less Need for Structural Grafts
- Preserves the upper lateral cartilages and avoids midvault destabilization.
4. Minimal Trauma
- Less aggressive bone and cartilage removal leads to faster healing, less bruising, and reduced postoperative swelling.
5. Shorter Operative Time (in selected cases)
- When anatomy allows, the technique can be more efficient than open hump resection and reconstruction.
6. Fewer Irregularities Post-Op
- Since the dorsum isn’t disrupted or rasped, the risk of surface irregularities or sharp edges is minimized.
Disadvantages and Limitations:
1. Not Suitable for All Cases
- Requires intact and symmetrical dorsal anatomy. Unsuitable for significant asymmetries or large, high-set humps.
2. Limited Control over Precise Dorsal Modification
- Fine sculpting is more difficult since the dorsum is preserved rather than reshaped.
3. Risk of Incomplete Reduction
- In cases with large cartilaginous humps, insufficient lowering may occur unless combined with other techniques.
4. Difficult in Revision Cases
- Prior surgery may have disrupted the anatomical planes required for successful preservation.
5. Requires High Technical Skill
- Success depends on a detailed understanding of anatomy and precise osteotomies.
6. Less Versatile than Structural Approach
- May not allow complex modifications such as dorsal width narrowing or specific dorsal shape tailoring.
Clinical Insight:
The push-down technique is best suited for patients with a moderate dorsal hump, a straight or slightly convex dorsum, and intact nasal architecture. It is especially advantageous in primary rhinoplasty cases where dorsal lines are aesthetically pleasing but require profile reduction.
Summary:

Recovery Faster, less swelling
Grafting Rarely needed
Ideal Patient Straight nose, moderate hump, intact dorsum
Unsuitable For Severe asymmetries, revision cases, large bony humps
Surgeon Requirement High expertise in preservation rhinoplasty
