title: Central neck dissection for the treatment of recurrent thyroglossal duct cysts in childhood.
abstract: OBJECTIVE
  The recurrence rate of thyroglossal duct cysts removed by the classic Sistrunk procedure exceeds 4%, even in skilled hands. Simple reexcision fails in 33% of these patients. Recent pathology literature suggests that the tracts of thyroglossal duct cysts may arborize, arguing for a wide-field approach to recurrent lesions. We describe the anatomic rationale and technique of an en bloc central neck dissection in children, on the basis of cadaver dissections and histopathologic review of recurrent thyroglossal duct cyst specimens.
  
  
  METHODS
  We reviewed the medical records of all the children undergoing surgery for thyroglossal duct cysts and fistulas during the years 1990 to 1998 by the senior author. En bloc central neck dissections were performed on several cadaver specimens to further delineate the anatomic rationale for this procedure.
  
  
  RESULTS
  We have performed an en bloc central neck dissection in 7 children, 5 with recurrent or multiply recurrent thyroglossal duct cysts. None has had a recurrence after follow-up of 9 months to 6 years. All have acceptable functional and cosmetic results.
  
  
  CONCLUSIONS
  An en bloc central neck dissection is a logical and effective surgical technique for the removal of recurrent or multiply recurrent thyroglossal duct cysts.
