Can a thin nose be made to look wider without breaking the bones? (photos)

There are several ways to increase the width of a nose and many reasons why this might be necessary. The best way to increase the width of the middle third or "middle vault" is by placing spreader grafts. Pieces of cartilage can be harvested, ideally from the septum, and placed along the dorsum of the nose extending from the nasal bones to the nasal tip. In a nose that is too narrow, this can add width, create aesthetically pleasing "dorsal aesthetic lines" and create a smooth symmetric attractive appearance. Spreader grafts can also help with overall nasal structural support and help correct nasal airway obstruction.

Spreader grafts can accomplish widening the mid-third of the nose by placement of these cartilage grafts underneath the concave upper lateral cartilages. For more information of many examples, please see the link and the video below

Based on your photo, the bridge of your nose looks like it fits your face well.  If I were to suggest any place for improvement (based on one image, which is not very reliable), it would be to give your nasal tip more definition to fit the bridge, not the other way around.  See a surgeon who can do 3D simulations and have a simulation done to show you how these changes will look before making a decision for surgery.
