Abstract

Objective: The objective of this selective EBM review is to determine whether or not “Submental deoxycholic acid injections reduce submental fat in adult patients enough to create a significant increase in patient satisfaction”

Study Design: Review of 3 double blind, randomized control trials that were selected based on their relevance to the clinical question.

Data Sources: All three peer-reviewed articles were found using PubMed and Cochrane Database. The keywords “ATX-101”, “submental fat”, and “deoxycholic acid” were used.

Outcomes Measured: Satisfaction with appearance in association with face and chin evaluated by a patient reported subject self-rating scale (PR-SSRS), a numeric scale with values from 0-6.

Results: All three trials recorded significant improvement in subject satisfaction compared to placebo with a p-value <0.001. The REFINE-1 study showed had an NNT value of 2 with 82.8% of the treatment group showing improvement compared to 31.0% of the placebo group. Ascher et al had an NNT of 3. 64.8% of the treatment group showed improvement with only 29.3% of the control group showing improvement. Finally, Rzany et al reported an NNT of 3. The treatment group had an improvement rate of 66.1% and the control group’s rate was only 28.7%.

Conclusion: Deoxycholic acid injections to the submental region resulted in a consistent improvement in patients’ satisfaction with the appearance of their submental region. The NNT values are low proving these injections to be effective in improving satisfaction.
