Clefts develop during utero and can affect either the lips, the palate or both structures. Specifically, a cleft lip results from the philtrum not coming together properly. A cleft palate occurs when the roof of the mouth does not close normally which leaves a wide opening between the oral and nasal cavities (Kummer, 2014). These craniofacial anomalies typically occur within the first trimester of pregnancy (Shah & Wong, 1980) and are evident in 1 to 2 newborns per 1,000 births (Robin, Franklin, Guyton, Mann, Woolley, Waite, & Grant, 2006).
A cleft lip and/or cleft palate are caused by internal and/or external factors (Kummer, 2014). Internal factors include chromosomes or genetic disorders, while external factors can either be environmental or mechanical. Common environmental factors are cigarette smoke, the anti-seizure medication Dilantin, or viruses like Rubella. Mechanical factors refer to specific body positions. For instance, if a baby has his or her head down constantly in utero, the tongue will lie on the palate and cause it to form really wide. This position results in a cleft palate (Kummer, …show more content…
Infants with just a cleft lip may require a change in position to facilitate their ability to obtain fluids from a nipple on a bottle or from their mother’s breasts. However, infants who have both a cleft lip and cleft palate require more than a change in position. These infants cannot properly seal their lips around their mother’s nipples or the nipples of standard bottles to produce negative intraoral pressure to obtain nutrients (Clarren, Anderson, & Wolf, 1987). Therefore, breastfeeding and the use of standard bottles are inefficient and will result in prolonged feeding periods that are beyond 30 minutes. During this time, the infant takes in excessive air which may cause fatigue, nasal regurgitation, coughing, or gagging and a loss of engagement (Clarren et al., 1987). Consequently, these children do not consume adequate amounts of nutrition and have difficulty gaining weight. Thus, SLPs use adaptive management approaches such as feeding products, techniques and nutritional knowledge to help facilitate the process of feeding and swallowing for children who have a cleft lip and/or palate and for their families (Reid,
