For this purpose, 3D images of 11 patients (9 women and 2 men), with an average age of 33.5 years, who underwent surgery in hospitals associated with the Residency Training Program, School of Dentistry of Ribeir\u00e3o Preto, University of S\u00e3o Paulo, from 2013 to 2019, were analyzed. The software Vectra M3 was used to calculate linear measurements, distance from lip surfaces, and areas. A significant decrease in the lower lip height (p = 0.0621), surface (p = 0.0435), and area (p = 0.0042), as well as an increase in upper lip area (p = 0.029), were observed from T0 to T1. All measurements remained stable from T1 to T2. Additionally, the ages of patients were correlated with the variables at T0, T1, and T2, and the data showed a strong correlation with height and distance of the lower lip vermilion, as well as lip width, particularly at T2. In conclusion, stereophotogrammetry proved to be a valuable tool for assessing soft tissue changes, revealing a significant increase in upper lip area and a decrease in lower lip area, as well as height, and distance from its surface.<\/jats:p>","DOI":"10.1590\/0103-644020256543","type":"journal-article","created":{"date-parts":[[2025,12,19]],"date-time":"2025-12-19T15:05:19Z","timestamp":1766156719000},"source":"Crossref","is-referenced-by-count":0,"title":["Assessment of lip morphology changes after bimaxillary orthognathic surgery using stereophotogrammetry"],"prefix":"10.1590","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9329-5471","authenticated-orcid":false,"given":"Juliana Rodrigues","family":"Rozatto","sequence":"first","affiliation":[{"name":"University of S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6213-7243","authenticated-orcid":false,"given":"Lucas Moura","family":"Sousa","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9955-2512","authenticated-orcid":false,"given":"Ana Maria Bettoni","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2137-5816","authenticated-orcid":false,"given":"Marco Antonio M.
