In children with simple cleft lip without cleft palate and cleft alveolar ridge, although the orbicularis oris muscle of the upper lip is not continuous and the sucking activity is weak compared with normal children, the oral and nasal cavities are not connected and the normal negative pressure is maintained in the mouth during sucking, and the muscle strength of both cleft lips can be improved to a certain extent through compensation, so there is no great difficulty in feeding these children and no special apparatus or special feeding method is needed; in children with cleft palate and/or cleft alveolar ridge, because the oral and nasal cavities are connected, the normal negative pressure cannot be maintained in the mouth during sucking and too much air is easily swallowed during sucking from the nose. Because the nasal cavity is connected to the mouth, the normal negative pressure cannot be maintained in the mouth during sucking, so it is easy to swallow too much air during the sucking process, and it is easy to choke milk out of the nose through the cleft in the palate. This design allows the flow of milk to be adjusted to an even flow rate so that the infant can easily control the flow of liquid and reduce the amount of air swallowed. When feeding, the infant should be held at an angle of 35-45° to the ground. This angle facilitates the flow of milk to the nipple due to gravity and prevents otitis media caused by milk flowing into the middle ear from the short, straight eustachian tube when feeding in a horizontal position. Adjust the teat so that it is located on the inside of the non-cleft side of the cheek and not at the throat. Gentle pressure on the bottle, together with the baby’s sucking action on the pacifier, makes it easy for the milk to reach the tongue and for the swallowing reflex to occur naturally, so that uniform and effective feeding can be achieved. The amount of artificial feeding should not be too much at a time, 60-80 ml is appropriate. In order to avoid excessive muscle activity in the wound after surgery and to promote wound healing by retaining food residues in the wound, the child should only be fed with milk-based total fluids within one week after cleft lip surgery and within two weeks after cleft palate surgery, during which active sucking activities, such as the use of straws, are strictly prohibited and replaced by milk pump dripping from the corner of the mouth. The wound should be flushed with water in the same way after feeding.
