title: Neuroanatomy of extensor digitorum brevis muscle for reanimation of facial paralysis.
abstract: OBJECTIVE
  This study explores the vascular and morphologic anatomy of extensor digitorum brevis (EDB), which can be alternatives to donor muscles used in functional muscle transfer in long-standing facial paralysis reanimation.
  
  
  METHODS
  A total of 14 EDB muscles from 7 embalmed cadavers were dissected and examined. Diameters and lengths of major and minor arteries supplying the muscle, venous pedicle diameter, neural pedicle diameter and length, their entrances into the muscle, the extendibility of neurovascular pedicles, when necessary, and the morphology of muscles were evaluated.
  
  
  RESULTS
  Mean results obtained for EDB muscle in the study were as follows: the longest distance between the starting point and the area where the tendon started was a mean of 5.1 ± 0.1 cm (range, 4.8-5.4 cm), the distance between the widest points was 4.2 ± 0.3 cm (range, 3.7-4.9 cm), the thickest area was 1.4 ± 0.8 cm (range, 1-1.9 cm), and surface area was a mean of 32.1 ± 1.2 cm (range, 29.8-35.7 cm). The mean length of the major artery is type 2 according to Mahtnes-Nahai classification and was found to be 2.1 ± 0.03 cm (range, 1.6-3.2 cm), and its diameter was found to be 1.95 ± 0.15 mm (range, 1.7-2.1 mm). Mean length and diameter of the nerve providing motor innervation to the muscle were found to be 2.3 ± 0.03 cm (range, 2.1-2.6 cm) and 2.4 ± 0.08 mm (range, 2-2.9 mm), respectively.
  
  
  CONCLUSIONS
  As a result of this preliminary study, we think that the morphologic and neurovascular structures of this muscle are suitable for use in long-standing facial paralysis reanimation.
