title: [Isolated bilateral macrostomia: case report and literature review].
abstract: BACKGROUND
  The macrostomia is a facial abnormality also called transverse facial cleft or Tessier cleft number 7. Macrostomia is a rare condition with an incidence from 1/80,000 to 1/300,000 live births. The left commisure is more commonly affected. Bilateral macrostomia is extremely rare, with only 10 to 20% of all cases of macrostomia, and 50% of bilateral cases are associated with different syndromes. To date just over 20 cases of isolated bilateral macrostomia have been described in the literature.
  
  
  METHODS
  We report the case of a patient with isolated bilateral macrostomia solved by surgery and with good aesthetic and functional results.
  
  
  CONCLUSIONS
  The treatment of bilateral macrostomia is surgical and should be done early. Although there are many techniques, the key is to recreate a new and correct commisure through a good reorientation of the orbicularis oris.
