Abstract : [Abstract] Part of a laminated fused epithelial sheet of the palatal shelves undergoes degeneration to disappear while the remaining part forms rosettes which develop later into cystic structures. Some of the cysts further grow to form epithelial pearls which persist until three years after birth. The remaining cysts or epithelial remnants are disrupted to disappear. Epithelial remnants in the nasal mucosa of the hard palate and those in the entire soft palate are promptly disrupted to disappear. None of the cysts could cause rupture of the palate. The fused epithelia of the eyelids are trilaminate from the beginning and never undergo disruption. No extraordinary epithelial cell proliferation is found to be related to loosening the fused eyelids. The disjunction of eyelids is motived by cell degeneration related to erupting eyelashes and secretion of the tarsal glands. No cleft lip or palate related to epithelial hypertrophy such as Barry suggested is found. Possibility of cleft lip formation related to epithelial cell hypertrophy in the nasolabial region is discussed.
