“…One study 27 reported that the hump was more and positively affected by facial height and less and negatively affected by anteroposterior jaw position. Four studies 28, 29, 34, 35 found no significant correlation of NLA (nasolabial angle) with any skeletal parameter, but one study 32 revealed its significant positive correlation with A point, Nasion, B point (ANB) and facial convexity. Two studies 27, 32 found that SFC (soft tissue facial convexity) increased with ANB and facial convexity (class II) and also with palatal-plane and mandibular-plane inclination to the cranium (high angles).…”

“…One study 30 found larger angular nasal measurements in class II. Two studies 21, 35 found increased nasal length in class III. Four studies 28, 29, 32, 34 reported an increase in nasal length and nasal depth with an increase in facial height and jaw length and also concluded that jaw length affected nasal parameters more than jaw position.…”

“…The included studies comprised 15 observational studies, out of which 3 21-23 were longitudinal and the rest 24-35 were cross-sectional in nature. Various authors had tried to relate the nose with different skeletal patterns: some with only sagittal patterns 21, 22, 24-26, 30 (skeletal classes I to III), a few with only vertical patterns 23, 33 (horizontal, vertical grower, low angle, high angle), and a few with both kinds of patterns (sagittal and vertical).…”

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.

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.

Nasal morphology is the keystone of facial aesthetics. Being the most prominent part of the face, the shape and position of the nose greatly influence the facial profile and nasal soft tissue thickness also plays a vital role in orthodontic diagnosis and treatment planning. Objective: To evaluate the soft tissue nasal morphology in individuals presenting with different skeletal patterns such as skeletal class 1 and skeletal class 2 jaw relationship. Methods: It was Comparative Cross-sectional study conducted in Orthodontics Department of Nishtar Institute of Dentistry for the period of six months (5th Mar 2020 to 6th Jun 2021). Study sample consisted of Lateral cephalometric radiographs of 65 subjects. Age range of sampled subjects was 19-26 years (mean age 20.93). The sample was divided into two groups on basis of the Skeletal jaw relationship as class-1 and class-2. An Independent t-test was applied for evaluation of the difference in lateral nasal morphology between both groups. Results: Notable differences were found between skeletal class 1 and skeletal class 2 groups for the prominence of the mandible and Linear distance between soft tissue Pogonion and Pronasale. Considerable differences in measurements of nasal depth, nasofrontal angle, nasal tip projection angle, nasofacial angle and nasomental angle were found. Conclusions: It is concluded that nasal morphology was greatly influenced by not only the underlying skeletal jaw relationship yet other factors e.g., dentition along with soft tissue thickness were also responsible for nasal morphology differences among various skeletal patterns. Gender dimorphism also exists for various nasal features.
