That depends on the type of nasal splint in question. External splints are used almost always, because some type of nasal bone reshaping is done as part of the rhinoplasty more often than not. When only nasal tip work is done, they may not be employed. When used they routinely stay on for two weeks. Internal splints are not used routinely. Typically, they are used in cases of the deviated nose or septum, where the partition of the two sides of the nose was reset. When used they are removed between postoperative day five and seven.
