title: [The applied anatomy of the periosteal flap composed of submental artery and dgastric muscle].
abstract: OBJECTIVE
  To provide anatomical basis for a new style operation using periosteal flap composed of submental artery, anteroventral portion of digastric muscle and submental artery for the renovation of laryngotrachea.
  
  
  METHODS
  The anatomical structures correlative with submental artery, submental vein, anteroventral portion of digastric muscle and mandibular periosteum in 23 (46 sides) cephalocervical samples were measured.
  
  
  RESULTS
  The periosteal flaps had shown many advantages inculding large transfer capacity, rich blood supply, flexibility.
  
  
  CONCLUSIONS
  It is feasible that the periosteal flap composed of submental artery, anteroventral portion of digastric muscle and mandibular periosteum is useful laryngotracheal renovation.
