title: [A retrospective study of orthodontic treatment of children with clefts].
abstract: OBJECTIVE
  To evaluate the population of cleft patients treated in a Department of Orthodontics and the types of treatment modalities provided.
  
  
  METHODS
  Demographic, cleft related and treatment related data existing in the patients' files were supplemented by questionnaires. Comparisons were conducted among 3 cleft groups: cleft lip (CL), cleft lip and palate (CLP) and cleft palate (CP).
  
  
  RESULTS
  The response rate was 36% (n = 152). The distribution of the patients in the 3 cleft groups, the sidedness, the male predominance and association with additional anomalies were similar to the reports in the literature. Most of the patients were the 3rd born (or more) and were of normal birth weight. Consanguity in the cleft families was at least 2.5 times more prevalent than that of the Israeli population and 30% reported on additional cleft in the family. Low birth weight and additional anomalies were found mainly in the CP group. Orthodontic involvement spanned 3 developmental periods: immediate postnatal presurgical treatment, phase I between the ages 6-8 years and full orthodontic treatment at a later age. Up to the age of 5 years only one lip operation was performed for 60% of the lip-affected children and one palate operation for 65% of the palate affected patients.
  
  
  CONCLUSIONS
  1. The distribution of the various cleft-related parameters in this retrospective study was similar to the findings in the literature. 2. The high prevalence of additional anomalies found emphasizes the need for a thorough examination of the cleft babies. 3. Orthodontic treatment was rendered in one and two phase protocols in addition to immediate postnatal pre-surgical intervention.
