No bones are broken during a nose suspension procedure. The reshaping of the nose is achieved through lifting the tip of the nose with double tipped needles and securing with special surgical thread. The technique can be likened to plastering a broken bone where the nasal tissue is supported against gravity until it clings into place.
The most effective way to make your nose smaller is via a surgical nose operation. All nose shapes are normal and, unless they are causing you breathing difficulties, should be regarded as perfectly healthy.
