Hello and thank you for your question. Filler and botox cannot decrease the alar base width. Based on your photograph, you may benefit from a tip refining rhinoplasty. Your surgeon can accomplish this by trimming, suturing, and reshaping the cartilage in your lower nose. Cartilage grafts may also be used to help improve tip refinement. You may also benefit from reduction of the alar base width with an alarplasty. Make sure you specifically look at before and after pictures of real patients who have had this surgery performed by your surgeon and not just a computer animation system. The most important aspect is to find a surgeon you are comfortable with. I recommend that you seek consultation with a qualified board-certified plastic surgeon who can evaluate you in person. Best wishes and good luck. Richard G. Reish, M.D. Harvard-trained plastic surgeon
