identified as influential to facial structure formation, and as causal for syndromic facial clefting. Nonsyndromic CL/P has been associated with the transcription factor forkhead box protein E1 (FOXE1), as mutations have resulted in cases of CL/P in mice. Other genes which have been found to interact with or contribute to craniofacial clefting include FGFRs, TWIST, MSXs, GREM1, TCOF1, PAXs, MAFB, ABCA4, and WNT allowing great cause for more research into the genetic basis for craniofacial disorders. Prevention Because the cause of facial clefts still is unclear, it is difficult to say what may prevent children being born with facial clefts. It seems that folic acid contributes to lowering the risk of a child being born with a facial cleft. Treatment There is no single strategy for treatment of facial clefts, because of the large amount of variation in these clefts. Which kind of surgery is used depends on the type of clefting and which structures are involved. There is much discussion about the timing of reconstruction of bone and soft tissue. The problem with early reconstruction is the recurrence of the deformity due to the intrinsic restricted growth. This requires additional operations at a later age to make sure all parts of the face are in proportion. A disadvantage of early bone reconstruction is the chance to damage the tooth germs, which are located in the maxilla, just under the orbit. The soft tissue reconstruction can be done at an early age, but only if the used skin flap can be used again during a second operation. The timing of the operation depends on the urgency of the underlying condition. If the operation is necessary to function properly, it should be done at early age. The best aesthetic result is achieved when the incisions are positioned in areas which attract the least attention (they cover up the scars). If, however, the function of a part of the face isn’t damaged, the operation depends on psychological factors and the facial area of reconstruction. The treatment plan of a facial cleft is planned right after diagnosis. This plan includes every operation needed in the first 18 years of the patients life to reconstruct the face fully. In this plan, a difference is made between problems that need to be solved to improve the health of the patient (coloboma) and problems that need to be solved for a better cosmetic result (hypertelorism).
