<unk>  diagnoses have a very poor prognosis or outcome with a death rate of 80–100% in newborn babies (either before delivery or shortly after delivery), primarily due to asphyxiation or suffocation from the tumor blocking the baby's airway. The course of the disease and outcome are dependent on many factors including size, location, and rate of development of the teratoma, all of which affect the magnitude of airway obstruction. Other complications such as the deformation of facial structure or deformation of jaw structure may impact the baby's ability to swallow and breathe, which may also negatively impact the prognosis as well. If the tumors are large, they might cause changes in the structure of face, nose and upper lips, to the point that they cannot be identified. Factors that may improve survival rates include early diagnosis of<unk>  before birth, multidisciplinary management in preventing obstruction in the airways, and feasibility in surgical removal of the teratoma. The prognosis can result in broad range of outcomes. In some cases, pregnancies were terminated after the fetus was diagnosed with<unk>  for different complications. The most common reason was that the tumor was continuing to spread even further in the head and mouth area. Very few long term survivors have been reported so the prognosis past the neonatal period is unclear.
