Preservation Rhinoplasty: The Endonasal Cottle Push-Down/Let-Down Approach
Friedman O, Ulloa FL, Kern EB.
What this paper says
A review presenting the authors' use of the endonasal push down and let down techniques credited to Maurice Cottle, which they describe as a new name for an old method.
Overview
The article addresses preservation rhinoplasty, lowering the natural bridge rather than removing the hump. The authors state they have used these techniques through their careers in selected patients. The stated advantage is that the bridge is managed conservatively, which reduces the need to routinely rebuild the middle third of the nose.
Sections of note
- Review and technique article; the abstract reports no patient numbers, no outcome measures, no complication rates and no follow up.
- Preservation rhinoplasty is described as a new term for an old technique.
- The push down and let down techniques are attributed to Dr Maurice Cottle.
- The techniques are performed endonasally, through incisions inside the nose.
- The authors state they use them on select patients, indicating patient selection matters.
- The claimed result is reduced need for routine restructuring of the middle third and the bridge.
- Excellent success is asserted without supporting figures.
What it means for a patient
- Conventional hump removal opens the roof of the nose and usually requires grafts to rebuild the middle third; these techniques avoid that step.
- Endonasal means no external scar across the strip between the nostrils.
- Only selected patients are described as suitable, though the abstract does not state the selection criteria.
- No data supports the claim of excellent success.
Why this paper matters
The preservation revival of the 2010s rests on methods first described decades earlier, and this article makes that lineage explicit. It records long term use by surgeons who never abandoned the approach. It supplies no measured outcomes to compare against modern structural techniques.
Terms
- Preservation rhinoplasty: keeping and repositioning the existing framework rather than removing and rebuilding it.
- Push down: lowering the nasal framework into the face after releasing it.
- Let down: lowering the framework after removing a wedge of bone at each side.
- Endonasal: performed through incisions inside the nose, leaving no external scar.
- Middle third: the section of the nose between the bony bridge and the tip.
