Purpose

The purpose of this study was to evaluate and compare the demographic characteristics of maxillofacial fractures between women and men in China.

Patients and Methods

The sample was composed of all patients who sustained maxillofacial fractures during a 10-year period (2000 through 2009). Incidences, age distributions, etiologies, fracture patterns, associated injuries, and occupation distributions were recorded and analyzed. Data analysis included the χ2 test, the Fisher exact test, and the t test. A P value less than .05 was considered significant.

Results

There were 1,131 patients (881 male and 250 female) who sustained maxillofacial fractures, with a male-to-female ratio of 3.5:1. Male patients sustained injuries most frequently during the autumn (P = .048), whereas female patients sustained more maxillofacial injuries during the summer (P = .006). Men sustained motorcycle (P = .023) and assault-related accidents (P = .036) more frequently than women, whereas women were more frequently injured in bicycle-related accidents (P < .001) or falling while at ground level (P = .001) than men. Women presented more frequently with condylar fracture than men (P = .028), whereas men were more prone to symphysis fractures than women (P = .037). For drivers, only men were involved (P = .001). Male workers sustained maxillofacial fractures more frequently than female workers (P < .001). Female children, students, and company staff were more prone to maxillofacial fractures than their male counterparts (P = .010, P = .004, and P = .044 respectively).

Conclusions

The demographic characteristics of maxillofacial fractures in female patients considerably differ from those in male patients.

Patients and Methods

Guidelines of the Declaration of Helsinki were followed in this investigation. The protocol, survey forms, and consent forms were approved by the institutional review board of Wuhan University (Wuhan, China). Written consent provided by the patients was waived by the institutional review board. The information and data were collected and standardized by an investigator based on case history, clinical and radiographic examinations, and medical records for each patient. Patients were excluded as

Results

Table 1 lists the gender distribution according to seasons. Statistical analysis showed female patients were more likely to have maxillofacial injuries during the summer than male patients (P = .006), whereas male patients sustained injuries more frequently during the autumn than female patients (P = .048).

Female patients younger than 20 years were more likely to have maxillofacial injuries than their male counterparts. In particular, a statistical difference in percentage distribution existed

Discussion

In this retrospective study, the occurrence and distribution of maxillofacial fractures between female and male patients were evaluated and compared. The demographic characteristics of maxillofacial fractures in female patients differed considerably from those of male patients.

More facial fractures occurred in male patients, with a male-to-female ratio of 3.5:1; consistent with findings in previous studies.9, 10, 12, 13, 14, 16, 21, 23, 29 However, it was still lower than in other developing19,

      It also should be noted that male drivers outnumber female drivers.15 It is interesting to note, however, that a study by Zhou et al16 (2015) in China found that women in the 11- to 20-year-old group were more associated with facial trauma than were men. This finding indicates that female individuals tend to take an early active role in society and is associated with the greater participation of women in extra-community activities, bringing them closer to men in risk groups in some countries.16,17

      We mainly found that male patients are significantly more affected then female patients (1.8:1). This is a common finding in many studies (Afzelius and Rosèn, 1980; Iida et al., 2001; Laski et al., 2004; Brasileiro and Passeri, 2006; Zhou et al., 2015; Boffano et al., 2015), as male patients have intense social interaction and an high rate of mobility, are more likely to take part in dangerous exercise practices, unsafe driving and interpersonal violence. Despite the fact that, in recent years, a gradual levelling of this gender difference was detected, probably due to a more active lifestyle among women, in our study, no significant variations of the gender ratio or trend during the 15-year period of observation were detected.
