A properly placed columellar strut is used to increase tip support. Sometimes it widens the columella, but if placed correctly, it usually does not. It can also be used to straighten the columella when the underlying cartilages are weak, buckled, or deformed.
Dear Rhal, In Rhinoplasty surgery there are many techniques that can achieve the goal of beautiful nose, as it is said - "There are many roads that leads to Rome". The columella strut can be use for strength or for elevating the nasal tip or increase the columella show. In my practice I do not use columella strut but rather use sutures and cartilage grafts to obtain the same goals. You have to realize that not all results are the same, because experience, skills and aesthetic eye are critical for good outcome. So do your due diligence carefully and choose wisely. Always, consult with experienced board certified plastic surgeons who do lots of rhinoplasty surgery in accredited surgery center for your safety. Most importantly, check the before and after pictures to make sure that they are numerous, consistent and attractive. Best of luck, Dr Widder
