Maxillary distraction resulting in facial advancement at Le Fort III level in cleft lip and palate patients: a report of two cases.


Zwahlen, R A; Bütow, K W (2004). Maxillary distraction resulting in facial advancement at Le Fort III level in cleft lip and palate patients: a report of two cases. Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology, 98(5):541-545.

Abstract

An 18-year-old female and a 14-year-old male who had previously received surgery for primary repair of a nonsyndromic cleft lip and palate (including alveolar defect bone grafting) unintentionally developed facial advancement at the Le Fort III level after surgical correction of their maxillary hypoplasia. The Le Fort I osteotomy, originally performed for their maxillary dentoalveolar hypoplasia, was an incomplete osteotomy. It was performed without down-fracture, leaving the pterygomaxillary and septal junctions intact. The gradual advancement of the maxilla during distraction osteogenesis was planned to correct the hypoplastic maxilla, and also prevent subsequent hypernasality; however, during the distraction procedure by means of a rigid external device both patients developed an unintentional facial advancement at the Le Fort III level.

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.
