Background: Nasal tip projection ideals have been based on the Caucasian nose; however, many racial groups have underprojected tips. Several methodologies have been described to measure ideal nasal tip projection. This study aimed to compare various methods to racially diverse groups to elucidate those best suited for race-specific facial morphology. Methods: An openly accessible artificial intelligence image generator was used to generate images of Caucasian, Middle Eastern, and African American noses. Tip projection was manually measured using 5 different ideal tip projection methods. One-way analysis of variance with post hoc Tukey honest significant difference test evaluated differences between racial cohorts. One-sample t tests were used for comparisons to previously described aesthetic ideals, and a P value of less than 0.05 was considered statistically significant. Results: Twenty lateral images were analyzed per racial cohort (10 men and 10 women). All racial groups—except for male Middle Eastern noses (P = 0.01)—were measured as ideal using the Byrd nasal length proportion method. Caucasian and Middle Eastern noses measured ideal using the nasolabial tip projection method. African American female noses measured ideal using the nasofacial tip projection method. Only Caucasian noses were ideal using the lip tangent method. Conclusions: This study suggests that the ideal nasal length to tip length ratio of two-thirds (67%) has generalizability across these racial groups; the lip tangent is an excellent method for evaluating tip projection in Caucasians; and assessment of ideal tip projection in Middle Eastern and African American groups should use regional midface and lower face anatomy to account for differences in facial morphology.

Objectives: In the present study, we compared patient satisfaction with classical tongue-in-groove (TIG) technique and triple cartilage combining suture (TCCS; flexible tongue-in-groove) techniques applied to the nasal tip in rhinoplasty. Methods: In this retrospective study, 80 patients who underwent rhinoplasty operations with TIG or TCCS techniques applied to the tip region were included. There were 40 patients in both groups. All patients in groups 1 and 2 were evaluated by the criteria written below at preoperative, postoperative first month, and postoperative first year: (1) Rhinoplasty Outcomes Evaluation Questionnaire (ROE), (2) tip projection (cm), (3) nasal dorsum length (cm), (4) tip projection ratio (Goode), (5) nasofrontal angle, and (6) nasolabial angle. Results: The patients were followed up at 84.32 ± 19.38 months in the TIG group and 87.47 ± 18.01 months in the TCCS group. Our results showed that preoperative, postoperative first-month, and first-year tip projection ( P = .013, P = .022, and P = .020, respectively), and nasal dorsum length values ( P = .009, P = .020, and P = .020, respectively) of the TCCS group were significantly lower than those in the TIG group. There was a positive correlation between the postoperative first month and postoperative first year ROE scores. Lower preoperative tip projection ratio (Goode) values and higher nasolabial angle values were related to higher ROE scores showing patient satisfaction. Conclusion: For the patient satisfaction after tip rhinoplasty, lower projection ratio (Goode) and higher nasolabial angle values were related to ROE scores. Although there are no significant results, lower tip projection results in the TCCS group may be related to more patient satisfaction due to natural appearance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
