Introduction: It is imperative to have a sound knowledge of causes and various aspects of facial asymmetry. Objectives: To evaluate asymmetry in the lower third of face, correlate the asymmetry with morphological features of the mandible, to correlate the dental and skeletal asymmetry in the mandible and to determine a correlation between these parameters and skeletal asymmetry at point menton using CBCT. Methods: Pre-treatment records of 15 patients (07 males and 08 females, aged 16.93 ± 2.19 years) with asymmetry of lower third of face due to unknown aetiology and chin deviated to right (Group A, study group) were compared with 15 patients (07 males and 08 females, aged 16.12 ± 2.06 years) presenting with no gross facial asymmetry (Group B, control group). Multiplanar Reformation view of CBCT data in sagittal plane was used to assess condylar height, ramus length and mandibular body length in both groups. Results: The mean condylar heights on both sides were similar in Group B (P-value > 0.05). The condylar height on right side in Group A was smaller compared to the left side condyles in both groups (P-value < 0.001). No significant difference was observed in mean ramus and body length between the 02 groups (P-value > 0.05). The skeletal midline deviation was higher compared to the dental midline deviation towards right in Group A (P-value < 0.001). Conclusion: Condylar height is an important factor responsible for asymmetry of the lower third of the face and deviation of chin in adolescent patients with asymmetry of unknown aetiology.

Introduction: Nose holds an anatomically strategic position on face which influences the facial aesthetics and soft tissue profile of an individual, making it indispensable to understand the variations in nasal features and influence of different factors on it. Present study aims at assessing nasal tip projection and nasal tip rotation among patients with different sagittal skeletal relations and vertical facial patterns in Maharashtrian population using photographic analysis. Materials and Methods: Records of 410 patients with age ranging from 17 to 25 yrs were selected from the institutional archives; to assess the nasal projection and rotation. Data obtained was divided into groups depending on the type of sagittal skeletal relation and vertical facial pattern and subjected to the statistical analyses. Results: Nasal tip projection was greater among patients with skeletal Class III malocclusion (mean 0.39) as compared to other malocclusion types, but did not differ significantly (P-value>0.05). Nasal tip rotation was clockwise among patients with skeletal Class III malocclusion and anticlockwise in Class I and Class II malocclusion patients, which was statistically significant (P-value<0.05). Amongst the patients with different vertical facial pattern, no statistically significant result could be obtained for nasal tip projection and rotation. Conclusion: The result of the present study gives an insight about the nasal features prevalent among different types of malocclusion, thus assisting the clinician in treatment planning and achieving good facial aesthetics with pleasing soft tissue profileKeywords

Aim: To assess improvement of soft tissue profile and upper airway dimensions in skeletal Class II adolescent patients treated with Forsus Fatigue Resistant Device (FRD). Material and Methods: This prospective observational study was planned with a sample size of 15 subjects (5 male & 10 female) diagnosed with mandibular hypoplasia as a cause of Class II malocclusion, requiring fixed functional therapy, with the inclusion criteria of age of 16-25 yrs with the ANB value range of 4°+2° with a non-extraction treatment plan. Pre-functional records were recorded once the leveling and alignment phase was complete and Forsus FRD attachments were placed. Treatment continued till the desired objectives were achieved. Post functional records were made at the end of functional therapy, after removal of Forsus FRD. Along with soft tissue analysis on lateral cephalogram, Acoustic Pharyngometry (AP) was recorded for each patient (Eccovision®” (sleep group solutions Florida, US) for airway changes before and after Forsus FRD. Results: Post functional treatment indicated statistically significant changes in nasolabial angle, upper lip position, upper lip strain, H angle and mento-labial sulcus. On evaluation of upper airway dimensions of the subjects by pharyngometry , there were statistically significant changes in mean upper airway volume and area. Conclusion: Study concluded that Forsus FRD is an effective method for correction of skeletal Class II malocclusion among adolescent patients, enhancing marked improvement in soft tissue profile of the patients, along with significant increase in volume and area of hypopharyngeal and oropharyngeal spaces, thus improving the upper airway patency.Keywords
