Precision Cephalometry and Pelvimetry

Cephalometry.

With the development of x-ray technology and its application to the craniofacial skeleton, numerous landmarks have been described and studied to better diagnose and plan treatment options for anomalies related to facial architecture. The following text serves to highlight the important landmarks and illustrate how they may be used to plan successful orthognathic reconstruction.

Pelvimetry in obstetrics.

Ultrasonic fetal cephalometry: percentiles curve.

Measurements by ultrasound of the biparietal diameter of the fetal head during pregnancy are a reliable guide to fetal growth. As a ready means of comparison with the normal we constructed from 4,170 measurements in 1,394 cases a curve showing the percentiles distribution of biparietal diameters for each week of gestation.

Supervised and Unsupervised Statistical Models for cephalometry

In this paper, we present an algorithm for aligning and matching unlabeled sets of points and a method for building a statistical model composed of a mean observation and associated variability. This model is used to solve the cephalometric problem. The main idea of this paper consists in using a dual step strategy: estimate the pose and then the correspondence alternatively. Correspondence bei...

Lateral cephalometry changes after SARPE.

Surgically assisted rapid palatal expansion (SARPE) is associated with postoperative cephalometric changes. In this study we analyse these changes in the sagittal plane in orthognathic patients undergoing SARPE followed by orthodontic treatment and Le Fort I, bilateral sagittal split osteotomy (BSSO), or bimaxillary surgery. This is a retrospective review of 50 patients (20 males, 30 females) u...
