3-Dimensional CBCT analysis of mandibular asymmetry in unilateral condylar hyperplasia.

Purpose: Three-dimensional quantification of asymmetry in UCH has not been reported yet, but would be useful for diagnosing and evaluating the degree of deformity in this disease. It enables profound decision-making and timing of surgery. Unilateral condylar hyperplasia (UCH) can subjectively be classified in hemimandibular elongation (HE), hemimandibular hyperplasia (HH) and a combination of these two (hybrid form).

Endoscopically assisted craniosynostosis surgery (EACS): The craniofacial team Nijmegen experience.

Introduction: An evaluation of our first 111 consecutive cases of non-syndromic endoscopically assisted craniosynostosis surgery (EACS) followed by helmet therapy.

Methods: Retrospective analysis of a prospective registration database was performed. Age, duration of surgery, length of hospital stay, blood loss, transfusion rate, cephalic index and duration of helmet therapy were evaluated.

Evaluation of the potential of automatic segmentation of the mandibular canal using cone-beam computed tomography.

We aimed to investigate the effectiveness of software for automatically tracing the mandibular canal on data from cone-beam computed tomography (CT). After the data had been collected from one dentate and one edentate fresh cadaver head, both a trained Active Shape Model (ASM) and an Active Appearance Model (AAM) were used to automatically segment the canals from the mandibular to the mental foramen. Semiautomatic segmentation was also evaluated by providing the models with manual annotations of the foramina.

Accuracy of assessing the mandibular canal on cone-beam computed tomography: a validation study.

Purpose: To establish the accuracy of cone-beam computed tomographic (CBCT) views in determining the position and diameter of the mandibular canal.

Materials And Methods: Two freshly frozen cadaver heads, 1 dentate and 1 edentate, were used to acquire CBCT scans. Measurements on cross-sectional CBCT images were compared with measurements on digitized histologic sections of the same regions in the mandibles.

Accuracy of bone surface size and cortical layer thickness measurements using cone beam computerized tomography.

Objectives: The purpose of this study was to determine the accuracy of Cone Beam Computerized Tomography (CBCT) reconstructions in displaying bone surface size and cortical layer thickness.

Materials And Methods: Two fresh frozen cadaver heads were scanned using a CBCT (i-CAT(™) 3D Imaging System; Imaging Sciences International Inc.).
