[Consultation for patients with cheilognathopalatoschisis and their family members. Cooperation between orthodontists and human geneticists].

In children with a cleft lip and palate the question of aetiology always arises. This is the case in particular when the neonatologist discovers or suspects additional malformations. Since newborn children with cleft lip and palate are now usually brought for initial treatment to an orthodontist, it is his responsibility to inform the parents about the possibility and necessity of genetic counselling and possibly, to initiate contact with the appropriate institute. This is always the case when the wish for further children is expressed. If the orthodontist recognizes microsymptoms in the parents or finds indications of their occurrence in the family, he will strongly recommend such a consultation, with cleft lip and palate patients, the orthodontist should discuss a genetic consultation as part of his confidential relationship with the patient so that the young patients understand the possible risk for the next generation. This consultation can bring enormous psychological relief for the patient if there is only a slight risk of recurrence.
