Epignathus
Epignathus
Epignathus (pronunciation: eh-pig-nuh-thus) is a rare type of oropharyngeal teratoma, a complex, usually benign tumor that develops in the oral cavity of a fetus. The term is derived from the Greek words "epi" (upon) and "gnathos" (jaw), indicating its typical location.
Definition
Epignathus is a congenital teratoma that typically arises from the Rathke's pouch, an embryonic precursor to the pituitary gland. It is characterized by its location in the oral and nasal cavities, often extending into the pharynx and neck. The tumor is composed of a variety of tissue types, including bone, muscle, and nerve tissue.
Symptoms
The primary symptom of epignathus is a mass protruding from the mouth or nose of a newborn. This can cause difficulty with breathing and feeding. Other symptoms may include facial deformities, cleft palate, and eye abnormalities.
Diagnosis
Diagnosis of epignathus is typically made prenatally through ultrasound imaging. The presence of a mass in the oral or nasal cavity of the fetus is a key indicator. Postnatal diagnosis can be made through physical examination and imaging studies.
Treatment
Treatment for epignathus typically involves surgical removal of the tumor. The timing and approach of surgery depend on the size and location of the tumor, as well as the overall health of the infant. In some cases, prenatal surgery may be considered.
Prognosis
The prognosis for infants with epignathus varies widely, depending on the size and location of the tumor, the presence of other abnormalities, and the success of surgical intervention. With early detection and appropriate treatment, many infants can survive and thrive.
