[Study on identification using frontal sinus computer radiographic films of Han population in Sichuan province].

OBJECTIVE

To study identical indexes of frontal sinus in different locative computer radiology.

METHODS

Frontal sinus radiographs were analysed by combining indexes of kinds of distances and patterns, further using descriptive study to describe frontal sinus and to analyse data statistically.

RESULTS

The 8-identical classification of frontal sinus was proposed, basing on the ratio of frontal sinus width and orbit width, the bilateral asymmetry, the superiority of side, the numbers of arches of upper borders (left and right), the partial septa (left and right) and the location of the central septa. There was no statistical significance of sinus between sexes (P>0.05).

CONCLUSION

Frontal sinus is tremendous inter-individual variation so it can be used for identification, but it can not be used for sex determination.
