“…It is conceivable that upper lip length increases due to maxillary overgrowth, and upper lip thickness augments in cases with maxillary retrusion due to soft tissue compensation, which is also confirmed by previous studies in other countries [ 5 , 32 , 33 ]. However, the significant decrease in nasolabial angle from Class II to Class III was contradictory to previous studies, including Burstone’s perspective that decreased nasolabial angle indicated maxillary protrusion [ 31 , 34 , 35 ]. In vertical dimension, the hyperdivergent group had a significantly larger nasolabial angle and upper lip length, and a significantly smaller superior sulcus depth and basic upper lip thickness, while the hypodivergent group exhibited opposite upper lip characteristics.…”

Background: Upper lip morphology is essential in diagnosis and treatment of orthodontics and orthognathic surgery. This study is aimed to evaluate the association between upper lip characteristics (ULCs) and skeletal patterns (SPs). Methods: 2079 patients were involved and grouped by sagittal and vertical. Class I, II, and III were identified by ANB angle, while normodivergent, hyperdivergent, and hypodivergent were identified by Facial Height Index and Sum of Angles. ULCs were evaluated by superior sulcus depth, nasolabial angle, upper lip length, basic upper lip thickness, and upper lip thickness. Confounders including demography, malocclusion, upper incisors, and upper lips were adjusted by multivariate linear regression to identify the association between ULCs and SPs. Group differences were evaluated with analysis of variance and Chi-square test. Results: The mean value of ULCs and prevalence of SPs were explored in the Western China population. ULCs were significantly different in various sagittal, vertical, and combined SPs. Superior sulcus depth was negatively related to Class II, and positively related to Class III and the hypodivergent pattern after adjusted by confounders. Conclusion: ULCs significantly varied among different SPs, while only superior sulcus depth was independently associated with SPs, indicating superior sulcus depth is the only ULC that might be significantly corrected by intervention of skeletal growth.

“…The difference was only statistically significant for Class II and Class III. This finding is in agreement with the study done by Arshad et al [ 25 ] and Perović et al [ 26 ]. They too found greatest NLA for Class II malocclusion followed by Class I and Class III, although the difference found was not statistically significant.…”

Background. With the changing paradigm from primarily hard tissue to soft tissue evaluation for orthodontic diagnosis and treatment planning, the priority has shifted to bring about improvement in the profile and smile characteristics of patients. Since not only the esthetics but also the stability of orthodontic treatment is largely determined by the soft tissue envelope, proper positioning of the soft tissue drape becomes paramount. Soft tissues of face, namely, nose, lips, and chin, are of paramount importance not only from an esthetic but also from functional and treatment stability points. Objective. To determine the morphological variation of lips, nose, and chin in different skeletal malocclusions. Materials and Methods. Lateral cephalograms of 237 patients visiting the department of orthodontics, BPKIHS, were taken, hand traced on matt acetate tracing paper of 0.002″ thickness with 0.3-mm 2B pencil. Samples were divided into 3 skeletal classes based on ANB angle. Measurements were made in relation to the nose, lips, and chin. Data were inserted in to SPSS and analyzed statistically using descriptive statistics, and mean and standard deviation was calculated for each variable. Multiple comparison between groups was done with post hoc Bonferroni test with mean difference significant at p < 0.05 . Result. On intergroup comparison, a significant difference was found for upper lip thickness (ULT) between Class II and Class III, and lower lip length (LLL) between Class I and Class III, and between Class II and Class III. Significant difference for nasolabial angle (NLA) was found between Class II and Class III. Similarly, a significant difference for the vertical chin parameter (CTV) was found between Class I and Class III, and between Class II and Class III. Conclusion. Both upper and lower lip thicknesses were highest for Class III followed by Class I and Class II, respectively. Lip lengths too were found to be highest for Class III skeletal relation. Nasolabial angle was larger in Class II malocclusion when compared to Class I and Class III. Similarly, both nasal length and nasal height measurements were in the order of Class III > Class II > Class I. Both horizontal and vertical chin parameters were larger for Class III sagittal relation.

“…The findings of our present study supported the above-mentioned study in aspects that nasal development and nasal profiles seems to get affected on sexual dimorphism and showed significant concurrence with another study done by Starck WJ et al 25 The present study stated that nasal profile gets affected on different skeletal classes of subjects i.e., there was statistically significant differences of nasal profiles in skeletal Class I, Class II and Class III subjects respectively which were affected by upper lip inclination and was further supported by the studies done by Taha A.A. and Ahmed A.S. and Perovic T.M. et al 26,27 Alhuwaizi A. et al conducted a study to evaluate nasolabial angle in Iraqi subjects with Class I, II and III skeletal relationships. They concluded that there was no gender variation detected in nasolabial angle.…”

Background: Orthodontic patients primarily seek treatment for aesthetic reasons and due to paradigm shift from hard tissue to soft tissue, nasal morphology with associated structure present in the middle third of face has drawn attention. Hence the retrospective study compared and correlated parameters between nasal morphology and gender dimorphism, skeletal pattern and skeletal malocclusion. Preorthodontic cephalograms of 180 patients were randomly selected following exclusion and inclusion criteria from North Indian population. Cephalograms were divided into three different groups according to various skeletal growth pattern, gender dimorphism and skeletal malocclusion and were further correlated with nasal parameters of each sample groups. Results: The results stated that there was a statistically significant correlation and differences were found between nasal parameters such as NLth(p=0.005), NTP(p=0.004) and skeletal parameters in males and females The results also explained that nasal parameters showed significant correlation with skeletal parameters among various growth pattern. There was statistically significant difference found NLth(p=0.035) and NTP (p=0.029) among growth pattern. On comparing nasal parameters in different classes of malocclusion, nasal parameter LNLA seems to be affected in all the three classes. Conclusion: The study concluded that nasal parameters get affected by growth pattern, skeletal malocclusion and sexual dimorphism in an individual.
