Microneurovascular Free Transfer of Extensor Digitorum Brevis Muscle for Facial Reanimation


V. K. RAO

J. A. BUTLER



Because of its size, several bellies, and long neurovascular pedicle, the extensor digitorum brevis muscle seemed ideally suited for use in facial reanimation; however, results have been unpredictable (1, 2, 3, 4, 5). Currently, use of this muscle in facial reanimation has been superseded by gracilis (6, 7) (see Chapter 153) and pectoralis minor transfer (8) (see Chapter 157) because of the larger size and greater power of these muscles.




ANATOMY

The extensor digitorum brevis muscle has four bellies with distal tendons; it is about 5 cm wide, 8 cm long, and 1 cm thick; and it is located on the dorsum of the foot (Fig. 156.1). Its origin is the lateral and superior aspect of the calcaneus. Its insertion is the lateral aspect of the extensor hallucis longus and extensor digitorum longus, which serve the second through fourth toes at the level of the proximal phalanx. It also may insert on the proximal phalanx of the big toe.
