Rene Le Fort, in 1901, carried out a series of
experiments on cadaver heads to understand fracture
patterns in upper jaw and classified mid face fractures
into few distinct categories, Le Fort I, II and III. The
primary goal of his research was to evaluate the diverse
midface fractures in order to comprehend the response of
mid face to various wounding agents having varying
velocities and masses at a particular time.
The aim of the study is to assess changing patterns of
mid face fractures using computed tomography scans.
Material And Methods
The study was carried out on the 100 patients who
reported to the OPD Of Rama Dental College, Hospital
And Research Centre, Kanpur And Regency Hospital
Kanpur. Patients diagnosed with mid face fracture who
were 15 years and above were selected. All the patients
were advised to undergo computed tomography scan and
the films were analyzed to study the exact nature of mid
face. The fractures were further studied intra-operatively
and compared with standard le fort lines. The data
collected was segregated in terms of age, sex and etiology
of trauma and categorized into three broad groups.
In our study, we observed that most of the cases the
fracture lines do not coincide with traditional le fort
lines(69%). In the 69 cases that were deviated from the
standard Le Fort lines, a total of 80 variations were found
either on same or both sides.
The study shows, CT as a useful tool in the diagnosis
of the midface fractures. There is a need for new studies
and research in this area because variations from the
traditional Le Fort patterns are occurring rather
regularly and necessitating extra places of fixation.
