RECONSTRUCTION OF CHIN AND LOWER LIP USING BILATERAL SEGMENTAL PECTORALIS MAJOR MYOCUTANEOUS FLAP WITH FUNCTIONAL SUPPORT

A 21-year-old man sustained an extensive high voltage electrical injury to his lower face, lower lip, chin, mandibular symphysis and floor of mouth. He lost all soft tissue as well as the outer cortex of the mandibular symphysis and lower teeth at the entry site. This soft tissue and skin loss was replaced by a left segmental pectoralis major myocutaneous flap [3] for lining of floor of the mouth and a right segmental pectoralis major myocutaneous flap augmentation of the chin and lower lip. The function of muscles and modiolus and orbicularis oris was reasonably regained by using bilateral temporalis muscle functional support [7]. The soft tissue on the left lower face was replaced by expanding the skin and soft tissue on the left submandibular area.
