Narrowing a bulbous tip is a common rhinoplasty request, after reducing a hump. Rhinoplasty is not one operation, but rather many potential operations. Tip rhinoplasty typically involves reducing the volume of nasal cartilage at the tip, in addition to bringing the cartilage together with stitches. For patients with thick skin, a small portion of deep tissue may be removed to thin the skin. Cartilage grafts are commonly placed to augment the tip and help in narrowing. Nostril narrowing requires removal of a small amount of skin at the junction of the nose and upper lip, which may be performed at the time of intial rhinoplasty or planned for a few months afterward.
Rhinoplasty has many potential risks, including but not limited to excess narrowing, pinching, or asymmetry. Only after a comprehensive evaluation can a rhinoplasty surgeon help determine appropriate options for you. It appears you may be at the early stages of your rhinoplasty research. Continue doing your research, and speak with some rhinoplasty surgeons in your area. Best of luck.
