Radiographic Study of Frontal Sinus Patterns and Nasal Septum Patterns Emphasizing their Implication in Personal Identification

Background: Morphometric analysis has been very popular among researchers. In the medical field, morphometric studies have produced significant results in personal identification, differentiating the populations of various races and ethnic backgrounds. This study was intended to evaluate the dimensions of frontal sinus cavities to observe the patterns of frontal sinus & nasal septum. Find out if there is any association between the frontal sinus and nasal septum parameters and their implications in personal identification. Methods: The data used in the study had to be collected from the archival records of digital X-rays so the study was based on a retrospective study design. Two hundred digital radiographic films were collected from both regions, consisting of 100 males and 100 females. The frontal sinus parameters were used to define the pattern for the nasal septum. Five main patterns were recorded. Data was statistically analyzed and descriptive stats, associations and inferences were generated. Results: The results revealed that 69% of males and 66% of females had a symmetrical pattern of frontal sinus. Combined use of FSP and NSP revealed interesting results. Conclusion: The frontal sinus can be used as an adjunct to other firm criteria instead of solely dependent on frontal and nasal sinus septum. However, it can be used to identify the ethnic background of a race.
