The surgeon, not the approach, is the important determinant

Having performed many open and closed rhinoplasty surgeries, I agreee that the visualization is much better with the open technique.  Having said this, excellent results can be obtained with the closed technique with a surgeon that is experienced and comfortable using that approach.  There are certain advantages and disadvantages with each approach and your surgeon will be able to discuss these during a detailed conversation.  Properly performed, the open approach rarely results in a noticeable scar across the columella.
