Can Spreader Graft or Onlay Camouflage for Small Dent Be Performed Via Closed Rhinoplasty?

Indeed spreader grafts are performed through closed rhinoplasty whether it is a unilateral or bilateral problem.  It is not a good idea to put fillers in the nose due to the disastrous complications that have occurred.  Small dents are easily addressed through a small spreader graft harvested from the internal portion of the nose, which is then inserted up underneath the affected upper lateral cartilage to make the dent go from a concave indentation to normal convexity to better match the opposite side.  

Treating a crooked nose after injury is challenging sometimes- but there area some very effective, permanent treatments that I use frequently with great success. 

The best technique in my practice for a limited indentation of the middle nose is to fill the area using  a closed rhinoplasty technique.  A sculpted or crushed cartilage graft can work well.   For larger areas I often use a diced cartilage graft wrapped in temporal fascia ( a soft graft material taken from the scalp area).  This is a very effective method. 

I find fillers unpredictable in their longevity.

I save spreader grafts for treating breathing problems from a narrow nose. 

Remember- if the "dent" is truly small, maybe no treatment is a good option!
