Objective To investigate the incidence of preoperative nutritional risk in patients with maxillofacial fractures,
and to compare the differences in general information and oral health-related quality of life between the patients with and with
out nutritional risk. Methods Convenience sampling method was used to administer questionnaires to oral craniomaxillofa
cial inpatients who met the nadir criteria within 24 hours of admission. The questionnaires included general information, oral
health-related quality of life questionnaire (OHIP-14), and nutritional risk screening score short form (NRS-2002). SPSS26.0
software was used to analyze the incidence of nutritional risk in patients with maxillofacial fractures and the differences in gener
al information and oral health-related quality of life between the patients with or without nutritional risk. Results A total of 201
questionnaires were distributed at this stage, and 195 valid questionnaires were collected, with a valid recovery
Data analysis indicated that patients with maxillofacial fractures were mainly male (68.7%), married (69.7%), and aged between
18 and 40 years old (54.4%). The highest percentage of education level was 74.9% in high school and below. Most patients had
no religious beliefs (94.4%). The source of medical expenses was mainly self-pay (65.6%). The highest percentage of monthly
family income was below 10,000 yuan (56.4%). The most common admission diagnosis was zygomatic arch fracture (45.1%),
followed by mandibular fracture (32.8%). The incidence of nutritional risk of maxillofacial fracture was 32.8% (NRS-2002 ≥ 3
points). The overall weight loss was (1.86±2.62) kg. The total OHIP-14 score was 39.02±11.81. The differences in total OHIP-
14 score, functional limitation latitude, physiological pain latitude, social impairment latitude, and disability impairment latitude
between the patients with or without nutritional risk were all statistically significant (P<0.05). Conclusion The prevalence of
preoperative nutritional risk is higher and the overall preoperative oral health-related quality of life is worse in patients with
maxillofacial fractures. Moreover, the oral health-related quality of life is worse in patients with nutritional risk compared with
those without nutritional risk.
