Fifty-eight rhinoplasty patients, treated at a tertiary referral center between 2020 and 2022, underwent preoperative and 12-month postoperative evaluations, using the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) and the visual analog scale (VAS). The preoperative and 12-month postoperative photographs were analyzed using Adobe Photoshop to assess changes in lip and smile positions. The study included 38 patients in the TIG with SEG group and 20 patients in the TIG without SEG group. The participants, with an average age of 32.12\u2009\u00b1\u20097.97 years, comprised 81% females. In terms of surgical outcomes, postoperative evaluations revealed significant improvements in the VAS aesthetic score, SCHNOS-O score, and SCHNOS-C score compared with preoperative scores (p\u2009&lt;\u20090.001) for both groups. Notably, both groups demonstrated significant improvements in the upper lip length, nasolabial angle (NLA), columellar inclination (CI) angle, and smile NLA. Patients in the SEG group exhibited markedly superior SCHNOS-O results, as well as distinctions in smile NLA and smile CI, compared with the group without SEG. The impact of rhinoplasty techniques on lip and smile remains complex requiring further evaluation. Both of the TIG techniques, with and without SEG, resulted in positive outcomes in terms of improving lip and smile positions, with the use of SEG demonstrating greater stability during a smile.<\/jats:p>","DOI":"10.1055\/a-2353-3477","type":"journal-article","created":{"date-parts":[[2024,6,26]],"date-time":"2024-06-26T19:20:04Z","timestamp":1719429604000},"page":"377-385","source":"Crossref","is-referenced-by-count":0,"title":["Impact
