Midface plays a vital role in contributing to facial aesthetics; despite this, there prevails a need for orthodontic literature to provide specific diagnostic criteria. We are blessed with ample literature to evaluate such, but due to some shortcomings, we lack to decide exact treatment plan. To clarify such limitations of various midface analysis, there is a need to consider the projections of the malar prominence in individuals with different skeletal mal-relationships. 40 subjects between the ages of 10 and 12 years, were equally divided into groups based on visual assessment of negative and positive vector relationships. Groups A and B comprised 20 subjects (10 male, 10 female) displaying a positive and negative vector relationship respectively. For both groups, Sella-nasion-Orbitale angulations were measured to evaluate the subjects’ anteroposterior position of the malar eminence relative to the cranial base. The angulation measurements obtained for SNO were smaller in the negative vector than the positive on an average of 5.9°, P < 0.05. No significant difference in values between males and females was observed. Visual assessment of vector relationships can effectively classify anterior malar projection which can be utilized to decide different orthodontic treatment modalities.

There is a lack of accurate three-dimensional studies to locate malar prominence for specified population, this study aims to locate the malar prominence using stable landmarks using CBCT. To derive a novel method to accurately locate the malar prominence and to assess and compare the malar prominence between males and females among Bangalore population using 3D CBCT study. All CBCT scans of study subjects belong to Bangalore population were collected from the pre-existing data available in Radiology imaging Solutions (CBCT centre), Bangalore during the period of September 10th to October 10th 2020. This is a descriptive study. A total of 42 subjects including 21 Males and 21 females were assessed using full skull CBCT scans which were converted to DICOM format and reconstructed into 3D images using NEMOCEPH 3D software. Landmarks used to locate the malar prominence were Fzs, Z, Zm and Ans. The intersection of these landmarks is considered to be as constructed maxillozygion(My). For the accuracy of the constructed Maxillozygion point (My), the distance between the actual Maxillozygion (Mzy) and constructed Maxillozygion (My) is measured and calculated between left and right halves of males and females. Three Orthogonal planes constructed were Midsagittal, Axial and Coronal Planes and the linear measurements with reference to all three reference planes in both the groups are measured. Student paired t- Test, Independent Student t Test, Mann Whitney Test. The mean distance from Mzy and my between right and left half of the face was compared using student paired t- Test. There is no significant difference (p=0.35).The mean values of the constructed anatomical landmark (maxillozygion) coordinated to three orthogonal planes between right and left sides of the face is compared using student paired T test and for both the genders (males and females) was compared using Independent Student t Test, and it is significantly higher in males as compared to females and it is statistically significant at (p=0.01). The location of malar prominence using CBCT by a novel method for Bangalore population is found which can be helpful in diagnosis and treatment planning for malar augmentation, camouflage treatment in subjects with midface deficiencies.

“…A comprehensive analysis of facial traits and supporting structures is central to enhance diagnosis, treatment planning, and quality of results [22]. Given the fact that both malar [23,24] and the jaws [25] are among defining components of the facial profile, any discrepancy in the balance between dentoalveolar and malar support may result in distorted nasal base-lip contour (Nb-LC), which may further compromise youthful appearance [24,26].…”

Background: This study aimed to investigate dental student's perception of facial attractiveness with regard to different combinations of anteroposterior malar-jaw positions using 3-dimensional (3-D) reconstructed images of subjects. Methods: Two Chinese young adults (1 male and 1 female) with straight profiles and average malar projections were selected for the study. 3-D facial images and cone-beam computed tomography images of these two subjects were superimposed using 3-D imaging software. Lateral and oblique views of nine different images were created by moving the maxillomandibular complex and/or zygomatic bone by 4 mm either forward or backward along the sagittal plane. One hundred three undergraduate dental students (n = 24, 33, and 46 students from the Year 3, 4, and 5, respectively) then scored lateral and 45°oblique view images of the newly reconstructed faces. Results: In the present study, images with a neutral malar and retruded jaws were found to be the most attractive in both male and female subjects. In addition, the Protruded malar (PM) group (p < 0.001), and the Retruded Jaws (RJ) group were rated more attractive (p < 0.001). Furthermore, the Relatively Prominent malar (RP) group was rated more attractive (p < 0.001) when malar-jaw relative positions were compared. Conclusion: This study shows that a neutral or a protruded malar favours facial attractiveness in both Chinese male and female subjects. Therefore, an appropriate relationship between malar projection and lower facial convexity should be taken into consideration while designing the orthodontic/orthognathic treatment plans for enhanced aesthetic outcomes.
