Resumo(s)
In 2009, a pit burial dated to the Bronze Age was excavated in Monte do Gato de Cima 3 (Portugal). The purpose of this paper is to describe the pathological absence of the left mandibular condyle noted in an adult male skeleton and to discuss possible diagnoses, including subcondylar fracture, cystic defect, congenital absence, condylar aplasia and mandibular condylysis. The most likely explanation for the pathological alteration is subcondylar fracture with non-union. Although the occurrence of non-union and slight osteoarthritic alterations in the left glenoid fossa were evident, this mandible was likely functional, as can be inferred from dental wear and muscle attachment sites. This trauma probably occurred before adult age when remodelling capacity is still high. Thus, bones and muscles adequately compensated for the trauma and only minor asymmetry developed. Consequently, this injury seems not to have greatly influenced masticatory functions. This is in accordance with clinical data, which demonstrate that, in growing patients, conservative treatment (non-surgical) results in good remodelling and patient recovery. In addition, in the few paleopathological cases published, the healing capacity of these types of mandibular fractures seems to be good, as can be inferred by evidence from the bone.
