It can additionally correct impaired breathing caused by innate structural defects in the nose.
Depending on which exact type of a surgery it is, a specific type of specialist is required. For example, a closed rhinoplasty may require an open rhinoplasty otolaryngologist (ear, nose, and throat specialist). Sometimes it takes a maxillofacial surgeon (jaw, face, and neck specialist), in order to create a functional, aesthetic, and facially proportionate nose.
In any case, the main aim of any rhinoplastic surgery, be it a cosmetic one (sought after for aesthetic purposes only) or a reconstructive one (the one which will fix any kind of damage or disease inflicted defects) is to make the form and function of the body part (in this case of a nose) to be intact and delightful to a patient!
