Abstract
Introduction: The nose is considered by some clinicians as the keystone of facial aesthetics. A treatment plan can be customized to intensify the facial aesthetics of a patient through careful evaluation of the soft tissue drape. Hence, for getting a better outcome of the treatment plan, orthodontists are supposed to have in-depth knowledge and awareness of soft tissue changes, taking into notice the ethnic and racial variation in discrete cohorts. The objective of this study is to enlist the relationship of nasal morphology with different dentoskeletal (sagittal and vertical) patterns. Materials and Methods: A comprehensive electronic database search was performed till July 2020, of Cochrane Library, Embase, PubMed, Scopus, Google Scholar, Web of Science, Wiley Online Library, and ScienceDirect. Only articles published in the English language were included. After excluding all the irrelevant data through careful screening, a total of 15 articles were selected which discussed the nose–dentoskeletal pattern relation. Results and Conclusion: The nose is found to be convex in skeletal class II, straight in class I, and concave in class III. Those with increased vertical growth may have an increased tendency of a convex nasal dorsum. Maxillary and mandibular jaw length affect the nasal parameters more than the jaw position. Nasal length and nasal depth increase with the jaw length and mandibular and maxillary/palatal-plane inclination to the cranium. A long nose with increased nasal depth is expected in long faces and those with long upper and lower jaws. An upturned nose is found with an anticlockwise-rotated maxilla.
