title: The interference of voice change on structural vocal cords lesions.
abstract: A longitudinal cohort study Introduction: Voice change may be defined as a group of changes in voice pattern that take place between childhood and puberty. During this period some vocal cord lesions (specifically cysts and nodules) may undergo transformation.
  
  
  OBJECTIVE
  To evaluate changes in vocal cord structural lesions following voice changes.
  
  
  METHODS
  All laringoscopic exams made at the Sao Paulo Santa Casa de Misericordia between 1997 and 2002 of children aged below 10 years with structural lesions were reevaluated. Children whose voice had already changed repeated the exam and answered a questionary about voice change.
  
  
  RESULTS
  Eleven children were studied. Observation showed that hoarseness was significantly decreased after voice change, and that lesions revealed modifications. Thickened-like lesions were reabsorved, and protrusion-like lesions underwent modification but did not disappear.
  
  
  CONCLUSIONS
  The definition of lesions and subsequent modifications after voice change are important to define the correct approach to children presenting hoarseness.
