What is Frankfurt line?
Frankfort horizontal line, Reid’s base line Reconstructive surgery An imaginary line that projects from the median line of the occipital bone and upper rim of the external auditory canal–the auricular point, to the lower rim of the orbit–the infraorbital point; the FHL divides the head into upper and lower halves from …
Why is Frankfurt plane important?
Automatic identification of the Frankfurt plane (FP) and mid-sagittal plane (MSP) of a human skull is a very important task. These planes are used to define important landmarks on the skull for surgery planning and guidance, forensic reconstruction, and anthropological and archaeological studies.
Which landmarks define the Frankfort horizontal plane?
The zygomatico-maxillary suture line crossing at the lower orbital rim. The point is located on the inferior margin of the orbit. Table 1. Definition of landmarks and planes….FH analysis.
| Name | Definition |
|---|---|
| Frankfort horizontal plane 1 (FH 1) | FH by connecting mid-Po, Or-R, and Or-L |
Who gave Frankfort horizontal plane?
Brodbent, [1] in 1931 introduced a “new X-ray technique” which provided a standardised method of recording craniofacial structures. The Frankfort horizontal plane; a plane extending from left Orbitale to both Porion points, was officially defined in 1884 in the anthropologic conference in Frankfort, Germany.Ram. 4, 1439 AH
Where is the Frankfurt plane?
Skull. In humans, the anatomical position of the skull has been agreed by international convention to be the Frankfurt plane or Frankfort plane, a position in which the lower margins of the orbits, the orbitales, and the upper margins of the ear canals, the poria, all lie in the same horizontal plane.
What is the purpose of anatomical planes?
Body planes are hypothetical geometric planes used to divide the body into sections. They are commonly used in both human and zoological anatomy to describe the location or direction of bodily structures.Dhuʻl-H. 23, 1441 AH
What is the meaning of vertical plane?
1 : a plane that passes through a vertical line. 2 : a plane of perspective passing through the point of sight and perpendicular to the ground plane and to the picture.
What is Frankfurt horizontal?
A horizontal plane extending through the lateral facial profile with the head in a normal relaxed position. If an imaginary line were drawn from the ear canal to the area just under the eye (infraorbital rim), this should be parallel to the ground.
What is the medical definition of the Frankfort horizontal plane?
Medical Definition of Frankfort horizontal plane. : a plane used in craniometry that is determined the highest point on the upper margin of the opening of each external auditory canal and the low point on the lower margin of the left orbit and that is used to orient a human skull or head usually so that the plane is horizontal.
How is anthropometric method used in everyday life?
Anthropometry represents a system of standardized and unified methods for the measurement of the human body, which, in addition to application in anthropology, finds its use in kinanthropology, medicine, ergonomics, fitness centres, criminology, industry (manufacture of clothing, furniture, means of transport, etc.) and other.
Are there any limitations to the use of anthropometry?
The only limitations to anthropometry are the properties and purpose of the measured problem itself. Anthropometry to an end, not an end in itself.
What are the components of an anthropometric scale?
Basic components include the anthropometer, personal scale, spreading caliper, pelvimeter, sliding caliper, soft metric tape and caliper. These are accurate, standardized instruments designed to measure the height, length, width and perimeter and determine the skinfold thickness.
