Current Trends in Management of Submental Liposis: A Pooled Analysis and Survey

Assessment and Treatment Strategies for the Aesthetic Improvement of the Lower Face and Neck

Background

Interest in aesthetic rejuvenation of the lower face and neck is growing, but published expert guidance is limited.

Objective

Review aesthetic concerns of the lower face and neck and provide expert guidance on evaluation and treatment.

Methods

Twelve international experts participated in an advisory board on lower face and neck aesthetic treatment. They completed a premeeting survey and met twice, reviewing responses and discussing patient evaluation and treatment strategies. They developed decision tree algorithms on patient assessment and treatment planning and sequencing, using clinical cases as a reference.

Results

Treatment concerns include neck and lower face skin laxity, structural bone deficiency, insufficient or excess volume, submental fat, jowls, platysma bands, and masseter muscle prominence. Advisors agreed that the lower face and neck may be the most challenging areas to assess and treat; treatment goals include lower facial contour and overall facial harmony/balance. Advisors recommended first ruling out a surgical approach, then determining whether midface treatment is needed to support the lower face, and lastly evaluating the lower face for significant submental fat, excess or insufficient volume, and structural bone deficiency. To treat the lower face and neck, an anatomical layer approach, moving from deep to superficial layers, beginning with structural support, was recommended. Assessment and treatment decision trees were based on this approach.

Conclusion

The lower face and neck are important but underrecognized areas of aesthetic concern. This article provides expert guidance and a suggested algorithm for assessment and treatment aimed at achieving satisfying and harmonious facial aesthetic results.

An Assessment of the Reduction of Submental Fullness With ATX-101 (Deoxycholic Acid Injection) in the Expanded Safe Zone

Background and objective Facial aesthetics have a huge impact on how individuals view themselves and are viewed by society. The aesthetics of the face are tremendously influenced by the shape of the chin and neck. In this study, we aimed to observe the outcomes in individuals after the use of ATX-101 (deoxycholic acid injection) in an expanded safe zone for submental fullness. To ensure optimal outcomes and reduce the risk of adverse events, appropriate patient selection is the key. ATX-101 treatment may be administered in combination with hyaluronic acid fillers, botulinum toxins, cryolipolysis, and radiofrequency treatment. This is the first study of its kind to be carried out at the national level in Pakistan. Materials and methods This was a quasi-experimental study conducted at the Rawalian Burn and Reconstructive Surgery Unit, Holy Family Hospital, Rawalpindi, Pakistan for a period of nine months, from 10-1-2021 to 11-10-2021. A total of 62 patients who fulfilled the inclusion criteria were enrolled. We recorded if any complications had occurred or not. Moreover, the total number of treatment sessions, the volume of injectables used, and the interval between sessions were also documented. ATX-101 package was injected into the treatment area. Due care was taken to avoid the region of the marginal mandibular nerve. After the procedure, outcomes and complications were observed. Results In this study, patient satisfaction was reported in 59 (95.2%) patients. After the fourth session, final improvement was observed in 59 (95.16%) patients. Tenderness was found in seven (11.3%) patients, bruising was noted in four (6.5%), edema was found in seven (11.3%), numbness was noted in one (1.6%), whereas paresis and alopecia were not found in any of the patients. Conclusion Our study concluded that ATX-101 is a very useful modality with fewer complication rates and is associated with significant improvement in the expanded safe zone for submental fullness.

Assessing the Efficacy of Deoxycholic Acid for the Treatment of Submental Fat: A Three-Dimensional Study

BACKGROUND

Deoxycholic acid is used for the treatment of excess submental fat, offering a potential alternative to more invasive surgical procedures. However, there is currently an absence of high-level evidence in the literature outside of Phase 3 clinical trials.

OBJECTIVES

The aim of this study was to evaluate the efficacy of deoxycholic acid for the treatment of submental adiposity by correlating objective 3-dimensional (3D) data with subjective patient assessment scores.

METHODS

Thirteen patients were prospectively enrolled into the study. 3D images were obtained prior to initial treatment, at 4-week intervals, and in the acute recovery period. Volumetric changes were calculated using Vectra software. Corresponding subjective surveys using the FACE-Q tool evaluated the perceived treatment results and side effects.

RESULTS

Objectively, there was a significant reduction in submental volume following treatment (P = 0.004), with total rounds of treatment averaging 3.4 (SD: 1.19). During the immediate recovery period, there was a statistically significant increase in submental volume, with an average increase of 8.68% (P = 0.0003). Subjectively, patient satisfaction scores improved significantly for both the aesthetics of the area under the chin and jawline (P < 0.005). Self-resolving paresthesia following treatment occurred in all study participants. There were no major complications. Participant scores of early treatment recovery also improved significantly with subsequent treatments (P < 0.005).

CONCLUSIONS

This study validates the use of deoxycholic acid for reducing supraplatysmal adiposity in the submental area. Objective volume changes showed positive correlation with subjective improvements in patient satisfaction scores. Recovery and side effect profiles were also described and may aid in future patient education and management.
