Determination of Gender from Paranasal Frontal Sinuses by Digital Radiography.
Pak J Med Health Sci Jan ;12(3):917-20.

Background: Establishment of individuality of unknown person is very important in forensic medicine. When only fragmentary remains are available such as skull, the identity can be determined by taking radiographs of frontal sinuses. These radiographs can also be helpful in gender ascertainment. Aim : To identify significant variables of frontal sinus that could be used to distinguish sex. Methods: This cross-sectional study was carried out at Outpatient Department of Radiology of Kuwait Teaching Hospital Peshawar Pakistan over a period of six months from March 2017 to August 2017. Posteroanterior digital radiographs of frontal sinus were collected from radiology department of Kuwait teaching hospital Peshawar. Maximum height, maximum width and areas of both frontal sinuses were evaluated in 100 radiographs each for males and females with a total of 200 subjects with age range 18 years to 45 years. Radiant Dicom viewer version 3.4.2 was used to take measurements. Results: The mean values of frontal sinuses were greater in men as compared to women. All six variables were significant predictors of gender (P<0. 05). Right height was better predictor for gender estimation based on binarylogistic regression with correct accuracy rate of 68.5%. Conclusion: Radiography is a low cost and reliable tool for sex determination from frontal sinus.
