If the size of nostrils are reduced, will breathing get bad?

 A full set of pictures are required to make any determination about what may be needed with the rhinoplasty procedure. When patient's have wide nostrils, an alar plasty can be performed to narrow them. There are a variety of techniques available to accomplish this. A full examination of the external and internal portion of the nose is required to  make sure there is no issues with nasal obstruction prior to the surgery.  The incisions  can be placed on the inside of the nose or at the alar junction. The dorsal hump is composed of both bone and cartilage and must be shaved down in order to remove it. Once the hump has been shaved down osteotomies are then required to close the open roof created from the hump removal.  For many examples  and more information, please see the link and the video below

Rhinoplasty can alter all aspects of your nose. If you nostrils don't need reduction, then none should be done. Please make a consultation to discuss details of your surgery.
