Teratomas develop in the head and neck region with a live birth (fetus shows signs of life after leaving mother's womb) incidence of 1:20,000 to 40,000. Due to the rarity of<unk> , the information gathered regarding incidence and prevalence is sourced from case reports. The occurrence of<unk> , a teratoma of the oropharynx, is extremely rare with a live birth incidence found to be 1:35,000 to 200,000. Of the reported incidents, epignathi was found to be more common in females than males (3:1 ratio), however there is no evidence proving an individual's genetics makeup will increase likelihood of developing this form of teratoma. The studies have shown having one child with<unk>  does not increase the chances of having pregnancies with this disease in the future. An estimated 10% of most epignathi diagnoses also report epignathi related abnormalities and deformities such as the formation of a cleft palate (split in the mouth's roof due to abnormal fusing of the hard palate during fetal development), hemangiomas (development of extra blood vessels), and more.
