The injuries were separated into five grades of severity based on neurological examination, including cranial CT. The injuries were also grouped into three categories based on facial regional involvement, using chi-square contingency table analysis. The data demonstrated that patients with upper facial fractures were at greatest risk for serious CHI. Injuries to both the mandibular and the midfacial regions with no upper facial involvement more frequently resulted in mild CHI with a modest likelihood of no neurological deficits. Trauma to only the mandibular region or to only the midfacial region was least likely to involve CHI.<\/jats:p>","DOI":"10.3171\/jns.1987.66.4.0542","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T12:18:00Z","timestamp":1241785080000},"page":"542-547","source":"Crossref","is-referenced-by-count":94,"title":["The impact-absorbing effects of facial fractures in closed-head injuries"],"prefix":"10.3171","volume":"66","author":[{"given":"K.
