title: Noninvasive treatment choice for an aged down syndrome patient presenting a residual periapical cyst.
abstract: OBJECTIVE
  This is the first report to illustrate the marsupialization as an effective treatment for a Down Syndrome (DS) patient presenting a residual periapical cyst.
  
  
  BACKGROUND
  These cysts occur within the alveolar ridge, usually at the local site of a previously extracted tooth that did not received proper curettage; usually the surgical excision of a cyst and also the vigorous curettage of a socket is very simple, if not for the fact that mentally disabled patients require rapid and non-stressful procedures.
  
  
  METHODS
  The 54-year-old DS patient represented herein received a minimally invasive marsupialization under local anesthesia. Due to the large extent of the lesion, the acrylic resin drain was maintained for 30 days. Through the following period, a daily irrigation of the cystic cavity with saline solution was carried out to prevent a secondary infection within the cystic cavity. A follow-up of 16 months showed no signs of recurrence.
  
  
  CONCLUSIONS
  Marsupialization of residual periapical cyst is completely effective and safe, even for a DS patient that is considered to be at an advanced age.
  
  
  CONCLUSIONS
  Marsupialization poses as a minimally invasive choice for mentally disabled patients, even when presenting advanced ages; treatment success was stated by the easy clinical conduct, uneventful postoperative situation and the lack of recurrence along 16 months of follow-up.
