Validation of Gender Identification From Frontal Sinuses Using Yoshino's Classification: A Morphometric Radiographic Study

Abstract

Introduction: Gender determination of deceased individuals may become necessary in scenarios involving sudden and unforeseen fatalities like explosions, fires, transportation accidents, or instances of mutilation or decomposition, which frequently require medicolegal expertise. Forensic radiology is instrumental in identifying gender. The shape of the frontal sinus is considered distinct for every person, differing even among identical twins, much like individual fingerprints and establishing personal identity.Aims and objectives: This study was designed to validate and determine gender identification by evaluating frontal sinus measurements using digital posteroanterior cephalograms with reference to Yoshino's classification and to determine gender based on measurements of frontal sinus size, bilateral asymmetry, the outline of the upper border of the frontal sinus, partial septa, and supraorbital cells of the frontal sinus.Materials and methods: A total of 300 digital posteroanterior cephalograms (150 males and 150 females) of age groups ranging from 18 to 30 years were collected from the records of the
