Although there are some surgeons who will only use either open or closed techniques for rhinoplasty, most rhinoplasty specialists will choose the technique best suited to your needs. In general, closed rhinoplasty allows for less refinement of the nasal tip than the open technique, although there are excellent surgeons who do use the closed technique for tip work. Suturing, graft placement, changes in rotation and projection, and other maneuvers are more precisely performed through an open technique in general. Closed revisions allow for alteration of the nasal bridge and less aggressive tip changes. Of course, a thorough discussion with a board certified plastic surgeon well versed in revision rhinoplasty is needed to determine the best option for you.Thanks for your question.
