Muscles Used in Facial Expression

4

 

Melvin A. Shiffman

 

 

 

4.1 Introduction

Facial expression is the mirror of our emotions. We express ourselves not only in words but in facial muscle contraction as well hand and body movement and body stature. Paralysis of facial muscles causes loss of expression of what we are trying to say or do. The face gives voice to what we are feeling.

The muscles used in human facial expression were reported by Duchenne de Boulogne in 1862 [1]. His research was through the use of electrophysiological

analysis stimulating each of the facial muscles and correlating the muscles stimulated with facial expression and taking photographs of the results (Fig. 4.1).

Duchenne described a variety of neurologic and muscular disorders such as Duchenne–Aran motor neuron disease (1849) [2], Duchenne’s pseudohypertrophic muscular dystrophy (1852) [3], and Duchenne– Erb palsy caused by upper brachial plexus injury during childbirth (1855) [4]. He was the first to use clinical photographs to illustrate neurological diseases (1862) [5].

4 Muscles Used in Facial Expression

4.2 Discussion

References

Surgery of the face is fraught with the danger of injury to motor nerves. Loss of facial nerve function is very distressing to patients. Surgeons should understand that not only can appearance be altered with motor nerve function loss but expression of emotions can also be altered. Perhaps in understanding what each facial muscle contributes to facial expression, the surgeon can understand the seriousness of the potential loss of any one of the muscles’ function.
