Effective clinical outcome of a mandibular distraction device using three-dimensional CT with volume rendering in Pierre-Robin sequence.

Computed Tomography (CT) with three-dimensional reconstructions was studied in cranio-facial deformities. The pre-operative and follow-up study of cranio-facial deformities can be performed with spiral CT. With this modality quantitative information can be provided in order to measure the entity of airway obstruction and the result of procedure affecting bone structures.
