Abstract

Facial palsy, or weakness of the facial muscles, arises from injury to the facial nerve and can lead to debilitating morbidity by affecting facial expression, speech, and daily activities. Playing a wind instrument, such as the saxophone, requires formation of an airtight seal with the instrument’s mouthpiece through a coordinated effort of facial muscles known as embouchure. Consequently, facial palsy can impair a musician’s ability to play a wind instrument. To address this functional disability, we present a novel 3D-printed embouchure-assistive device designed for application in saxophone players with facial palsy. Quantitative and qualitative metrics were recorded, demonstrating improved duration of note sustain, increased mean air pressure within the mouthpiece during play, and subjectively improved patient comfort and overall tone quality with use of the device.  We also include design iterations of the prototype device as they may serve as a template for broader applications in musicians with facial palsy.
