DOI: 10.1001/jamafacial.2016.1115
Abstract: Importance Aberrant depressor anguli oris (DAO) activity may arise after recovery from acute facial paralysis and restrict movement of the oral commissure. Objective To quantify the degree to which DAO inhibition affects smile dynamics and… read more here.

DOI: 10.1097/prs.0000000000008807
Abstract: Background: Nonflaccid facial palsy is a debilitating entity characterized by hypertonicity, synkinesis, and hypomobility. Patients with nonflaccid facial palsy often have smile asymmetry and restriction because of disruption of normal vector forces on the modiolus.… read more here.

DOI: 10.1097/prs.0000000000009283
Abstract: Summary: The complexity of facial synkinesis will likely benefit from an individualized approach to intervene on discrete synkinetic facial subunits. This overarching treatment algorithm requires understanding each synkinetic mimetic subunit. The depressor anguli oris muscle,… read more here.

DOI: 10.1097/prs.0000000000010287
Abstract: BACKGROUND In facial palsy (FP) patients synkinesis of the Depressor Anguli Oris muscle (DAO) is a common pathology impairing dynamic and resting facial symmetry. This prospective study utilizes high-resolution ultrasound (HRUS) to evaluate the morphological… read more here.
