摘要

Objectives: This talk aims to explore the revitalization of the depressor anguli oris (DAO) muscle and the treatment of marionette lines through the use of toxin injections. The objectives of this presentation are to provide anatomical insights into the DAO muscle, demonstrate effective injection techniques, and present the outcomes of a clinical study. By understanding the underlying anatomy, refining injection techniques, and examining clinical results, practitioners can achieve successful outcomes in addressing DAO-related concerns and rejuvenating the marionette lines. Introduction: The depressor anguli oris muscle and marionette lines are common concerns in facial aesthetics, as they contribute to a tired and aged appearance. Toxin injections targeting the DAO muscle have shown promise in rejuvenating the lower face, providing a non-surgical solution to address marionette lines and oral commissure downturn. This talk aims to provide a comprehensive introduction to the anatomical insights of the DAO muscle, effective injection techniques, and the clinical study outcomes highlighting the success of toxin treatments in revitalizing the DAO and treating marionette lines. Materials / method: The talk will utilize a combination of didactic lectures, anatomical illustrations, and clinical study data to convey the methods employed in understanding the anatomy of the DAO muscle, perfecting injection techniques, and presenting clinical study outcomes. Attendees will be guided through the intricate anatomy of the DAO muscle, including its origin, insertion, and functional implications. Injection techniques targeting the DAO muscle and marionette lines will be demonstrated, emphasizing accurate needle placement, dosage, and injection depth for optimal outcomes. Results: By the end of the talk, attendees will gain a comprehensive understanding of the anatomical insights of the DAO muscle and its role in facial aesthetics. They will learn effective injection techniques to address DAO-related concerns and revitalize the marionette lines. The presentation of clinical study outcomes will showcase successful results achieved through toxin treatments, demonstrating improvements in oral commissure downturn and marionette lines. Conclusion: Revitalizing the depressor anguli oris muscle and treating marionette lines through toxin injections offers a non-surgical approach to lower face rejuvenation. By understanding the underlying anatomy, refining injection techniques, and examining clinical study outcomes, practitioners can confidently and effectively address DAO-related concerns.
