A longitudinal cephalometric study from age 5 to 18 years on individuals with complete bilateral cleft lip and palate


Gnoinski, W M; Rutz, G (2009). A longitudinal cephalometric study from age 5 to 18 years on individuals with complete bilateral cleft lip and palate. Journal of Craniofacial Surgery, 20(2 Supp):1672-1682.

Abstract

Development of the facial profile between age 5 and the end of pubertal growth in patients with complete bilateral cleft lip and palate was studied by means of cephalometric x-rays taken at the age of 5, 10 and 15 years as well as at the end of the growth period. All 29 patients had been treated according to the same plan and operated upon by the same surgeon. Values for the ANB angle are typically very high in 5 year old children, and then decrease to values corresponding to those of the general population by the end of the pubertal growth period. Vertical development maintains the initial pattern; no compensatory vertical excess was observed. Due to the wide range in all measurements, the value of age-related mean values in a patient sample is of little consequence for individuals but can point out tendencies.
The multidisciplinary concept of maintaining the initially protrusive position of the premaxilla by means of a passive plate at the newborn and infant stage, as well as using surgical procedures with limited retrusive effect proved to be correct in the long run: At the young adult stage the angle ANB remained positive for almost all patients except for those with multiple tooth agenesis in the upper arch. A potential benefit of two-stage palate repair is seen
in the neutral vertical development of the patients examined. This hypothesis is supported by comparison with other studies from the literature.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
