The auricular cartilage,which is typically soft and flexible,can calcify or ossify because of diseases such as diabetes mellitus,trauma,radiation therapy for cancer,and more commonly from frostbite.Calcified,ossified,or hardened auricular cartilage is a rare finding in the clinical literature and appears to be absent in the physical and forensic anthropological literature.This study examines the ossified auricular cartilage and tests whether the hypothesis can be identified in postmortem skeletonized tissue and be part of the external auditory meatus.A total of 290 crania were examined for accessory ossicles.A descriptive and interpretative analysis was performed grossly,histologically,and morphometrically to document the morphology and location of the ossicles,investigate their structure,and perform hypothesis testing.Results revealed that seven females and one male crania from a total of 290 crania(2.76％)exhibit semi-ossified auricular cartilage attached to the tympanic plate of the temporal bone.The morphology and location of the ossicles at the junction of the auricle and external auditory meatus indicate they are hardened auricular cartilage that was verified with histological observations.Regression analysis indicates that addition of the ossicle to the depth of the auditory tube significantly changes coefficient of determination(R2)with respect to cranial breadth.In conclusion,results indicate that small cartilaginous structures of the external ear may ossify forming accessory tympanic plate ossicles that potentially could be identified in skeletal remains as a new osteological entity.This report highlights the types of information that can be gained using an approach that integrates forensic anthropology,gross anatomy,and histology.
