In most cases, a surgeon will address the tip in any rhinoplasty procedure, because the nose is operated on as a whole and is also part of a bigger whole - your face. However, this mainly entails smaller adjustments of the nasal tip. If we are talking about cases without the "standard" bump on the nose, that don't require a size reduction, are not crooked, etc, but have some sort of issue with the nasal tip, there is also a range of things that can be adjusted - from narrowing of the nasal tip, alar base reduction (narrowing of the nostrils), correction of alar retraction (when the nasal holes are too visible, that is the alar arch is too high), droopy nasal tip, etc. Some of these aspects can be corrected or altered via closed approach, but some may require open rhinoplasty, which leaves a small scar on the columella. Alar base reduction also leaves a small scar in the crease of your nostrils, since they are literally being reduced in size and repositioned, to achieve a more narrow base of the nose (the width of the nose is being reduced). Depending on the skill level of the surgeon, as well as individual aspects of each patient (skin, healing, etc.) those scars may be more or less visible. A droopy nasal tip can be corrected with several methods, but it requires an insertion of a material (a graft taken from your septum or ear cartilage, etc) to define and support the nasal tip. Some surgeons use open, some closed rhinoplasty for this. These are just some of the options and methods available. If you're considering having surgery just on the tip of your nose, choose a surgeon who is experienced in this field and can offer you the best possible solution to achieve your desired outcome. Also, keep in mind that, although these procedures do not require the breaking of any bones, it is still surgery and the tip is the most sensitive part of the nose, so the swelling there is present for the longest.
