Cephalometric computation and analysis is the clinical description and presentation of cephalometry.
It is a thorough investigation of the dental and skeletal relationships of a human skull. It is often taken into consideration by dentists, orthodontists, and oral and maxillofacial surgeons as a treatment planning tool and instrument.
Steiner analysis and Downs analysis seems more popular.
Though there are other methods aside the two such as tweeds analysis, soft tissue analysis and so on.
Cephalometric analysis relies heavily on cephalometric radiography to study existence and relationships between bony and soft tissue landmarks on the craniofacial complex. It can be used to diagnose growth of anomalies prior to treatment, in the middle of treatment to assess progress, or at the end of a treatment to confirm whether the goals of a treatment have been met and established.
"A Cephalometric radiograph is a radiograph of the head taken in a Cephalometer (Cephalostat) that is a head-holding device introduced in 1931 by Holly Broadbent Sr. in USA. The Cephalometer is used to obtain standardized and comparable craniofacial images on radiographic films."Source
Machine and Dimensions of Cephalometry
"To carry out cephalometry, the X-ray source is placed a steady five feet away from the mid sagittal plane, with film situated just 15 cm from there. This allows for accurate measurements to be taken and recorded"Source
For instance, an object-to-film interval distance
14cm and a source-to-object of 5 feet distance, the enlargement of all the parameters is lowered equally in three dimensions.
When trying to visualise a patient's anatomy through lateral and frontal cephalograms, the big issue sets in due to these images being in two-dimensional forms of projections of three-dimensional structures.
Magnification and distortion that always followed after the conduction of traditional radiography further compounds the problem of blurring important details and features of the craniofacial complex.
That's all as regards the write-up on this post more would be discussed in the subsequent posts and happy blogging.
