Can Cutting the Depressor Septi Muscle Affect my Smile in the Long-term?

I will be going through rhinoplasty surgery soon where, amongst other things, my depressor septi muscle will be cut to prevent my nasal tip from drooping when I smile. While I understand that this procedure is not very difficult, I am worried that my smile or, more specifically, my upper lip movement will be negatively affected by the procedure. From your experience, is this something to be concerned about or does one always regain full upper-lip movement after a while? Thank you very much.
