Abstract
Relevance. Facial paralysis is a common neurological illnesses of the maxillofacial region. Gold standard of dynamic correction of permanent facial paralysis is gracilis muscle transfer. However, using this flap is impractical or impossible in some cases. There are few domestic and international publications about extensor digitorum brevis muscle for facial reanimation surgery.
Purpose. Assessment of muscle variability on the dorsum of the foot; analysis of blood supply and innervation of the extensor digitorum brevis muscle.
Materials and methods. Operations performed on 10 unclaimed corpses: dissection of the extensor digitorum brevis muscle, as well as the blood vessels and nerves of the dorsum of the foot. The legal and ethical requirements for such studies were observed planning the design of the study and during work.
Results. As a result, in 80% of cases, was found a typical anatomy of muscles, blood vessels, and nerves in the dorsum of the foot. In 10% was found a typical anatomy of muscles and nerves, but there was no lateral tarsal artery – the branch of the dorsal artery of the foot. Blood supply to the extensor digitorum brevis muscle performed by perforating branches of the peroneal artery. In 10% was found subtotal atrophy and fibrous degeneration of the extensor digitorum brevis muscle.
Conclusions. The use of the extensor digitorum brevis muscle is a perspective method for the treatment of facial paralysis. Harvesting of this flap is complicated.
