What is the Difference Between Alar Rim Graft and Alar Batten Graft?

Overly pinched nasal ala need to be corrected by supporting the ala back toward its normal convex shape. It may also involve lengthening or stretching the ala downward. In both of these cases an alar batten graft is useful. An alar rim graft specifically addresses notching of the ala or retraction of the ala from removing too much marginal tissue. This is placed at the end of the existing alar cartilage along the nostril rims to stretch the skin downward. Finally, sometimes lateral crural grafts are needed as well to add rigidity back to the alar regions to support it from collapsing and they go underneath the existing alar cartilages to give it strength like a brace. I hope this information helps.

An alar batten graft is a cartilaginous graft usually composed of septal cartilage that is placed in the pyriform aperture and inserted underneath the lower lateral cartilage to bolster a weak lower lateral cartilage.
An alar rim graft is a small sliver of cartilage placed literally at the nostril rim to prevent a notched rim. Both grafts are used to prevent collapsing, especially upon inspiration and breathing.
Neither one of these grafts will increase the projection of the tip itself. An alar batten graft will help with a pinched nasal tip by giving it some whiff. Adding projection to the nose will not straighten the alar rim if there is weak and flail cartilages.

You would be surprised how much improvement you could see in your nose with an Injectable Filler treatment. Non-Surgical Rhinoplasty is not right for all nasal irregularities, but it does work well for improving a pinched tip, and for lowering retracted nostrils.
You should consult a board-certified Rhinoplasty specialist familliar with the art of using fillers in the nose. You should see many photos before you proceed.
Alar batten grafts are used to correct a pinched tip, and alar rim grafts are used to lower retracted nostrils. In my personal experience, Silikon-1000 works well for both of these conditions. All without the expense, inconvenience, risk and downtime associated with Revision Rhinoplasty Surgery.
I hope you find this helpful.
