Do I need an alarplasty or a full rhinoplasty? (photos)

It depends upon what's bothering you. If your wide nostrils are bothering you, just perform an alar-plasty which narrows them. They're asymmetrical now, and they will still be asymmetrical after the surgery, just narrowed. An alar plasty can be performed under local anesthesia. If you want to narrow your bridge line, that's a full rhinoplasty and that must be done under general anesthesia, since it's bone work. Your side profile does not need any improvement. You could always do the alar plasty first, and after a year or so if you're still unhappy with your nose, you can always undergo a full rhinoplasty.

Hi and welcome to our forum!
From your photos, I note a small notch deformity at the free margin of the nostril rim.
We recommend that you undergo treatment to the specific areas of your concern. Narrowing the nose will not correct the notch (the nose can be narrowed if this is of concern to you). A tip-plasty will increase tip definition. Addition of a small cartilage graft will fill out the depression and excision of the alar bases will narrow the nostrils and correct nostril flare.
