Cleft Palate is indicated by a fissure extending through the soft palate alone, or through both soft and hard palates, and which may be combined with single or double hare-lip, in which case the intermaxillary bones are frequently displaced.
When the cleft is confined to the soft palate, the operation of staphylorraphy may be performed; when, however, the cleft is through both soft and hard palates, the construction of an artificial obturator and palate combined will often prove successful in correcting the voice and preventing much inconvenience in partaking of food and drink.
