“…A possible cause of nontraumatic coronoid process fractures may be acute reflex contraction of the temporalis muscles, leading to a coronoid stress fracture. 7,8 The present case reports coronoid process fracture complicated with refracture after plate fixation, which appears to be a mechanical failure in the plate.…”

Summary: Mandibular coronoid fractures are mainly the result of motor vehicle accidents, followed by assaults and falls. We report a case of failure of miniplate fixation in a coronoid fracture. A 57-year-old man fell onto his face from a 3-m height. Panoramic radiography and computed tomography confirmed a right tripod fracture, a LeFort I fracture, and a right coronoid process fracture. On day 6 posttrauma, open reduction and miniplate fixation were performed. Instead of performing intermaxillary fixation, we recommended consumption of a soft diet for at least 1 month. On postoperative day 30, while opening his mouth to eat, the patient felt a strange sensation in his right cheek and heard a clicking sound. He then began to feel pain and had difficulty chewing. On postoperative day 40, follow-up panoramic radiography revealed breakdown of the previously fixed miniplate. Pain and difficulty chewing continued, and coronoidectomy and plate removal were performed at 18 months postoperatively. It is thought that a miniplate large enough to withstand the pull of the temporalis muscle should not be applied to a fractured coronoid process due to the shallow anterior border of the coronoid process. Although the patient’s quality of life, feeding and oral hygiene care are a big burden of care in postoperative intermaxillary fixation, rigid internal fixation and intermaxillary fixation for at least 1 month are recommended in patients with significant displacement of a fractured coronoid process or limited mouth opening.

“…In such cases the piece that breaks off is unlikely to greatly dislocate. 43 Descriptions in the literature also mention the possible occurrence of inflammation as a result of the trauma. Enlargement of the coronoid process can be accompanied by syndromes such as trismus-pseudocamptodactylia.…”

In 2014, we had the opportunity to study a Bronze Age multilayered settlement at Boconád-Alatka-puszta within the framework of a KEOP project. The site is located in the southern part of Heves County, northeast of Boconád. On the basis of archaeological research, the examined settlement layers can be connected to the Hatvan culture. In the central part of the settlement, surrounded by a ditch, human bones, i.e. fragments of skeletal bones and skulls of a child and an adult were recovered, concentrated in the same area, at the lowerpart of the plowed layer and the gray layer below it. Shell jewellery and a bone tool observed at the level ofthe bones were presumably the remnants of grave goods. It is certain that, taking advantage of the features of the place, the burials might take place after the abandonment of the settlement. Due to the extent of the disturbance, the results of scientific research may give the answer to who buried here and when.
