Different techniques to hide excess columella show? (Photo)

Columellar show is affected by the shape and orientation of the columella in relation to the alar rims.  A number of maneuvers are present to lower the alar rims (rim grafts, LLC repositioning, composite grafts etc) or raise the columella (tongue-in-groove, medial crural overlay, excision of vestibular tissue et cetera et cetera).  As a patient it's usually most effective to choose the surgeon you are comfortable with, get on the same page with him/her in terms of your aesthetic goals, and then defer to him/her with regard to which techniques are the best for your nose.  

 From the photographs it does not appear to me that you have excessive columella show. When the situation does exist it most often is due to the medial foot plates of the lower lateral cartilages. These can be adjusted the time of a conventional rhinoplasty. Sometimes work on the nasal septum or nasal spine may be part of the treatment.

At the time of the rhinoplasty, the hanging columella can be trimmed accordingly  and excess skin and cartilage can be trimmed to prevent the hanging columella. Depending upon where the incision is made in the columella can determine whether or not surgeons can raise the tip, lower the tip, or simply tuck in the columella from hanging and keep the existing angle.
