To discuss how to choose the optimal timing of the fracture in the burn patients with maxillofacial fracture through summarizing the clinical cases.

There were 48 patients of burn and scald with maxillofacial fracture from June 2003 to August 2016 in the first affiliateed hospital of PLA general hospital. Male was 32, female was 16. Age was from 17-45 years old, average age was 35±12 years old. Thirsty six patients had 60 fractures of the mandible, 12 patients had 20 fractures of the maxilla. Burn area was from 34%-76% total body surface area (TBSA). Two groups of patients were treated with burns therapy and maxillaris and facial theray. On the basis of their reduction of fracture operation time, the patients were divided into two groups. The experimental group: an operation after the shock and before the infection time(after injury 1-3 days) . The control group: an operation after the shock time(after injury 4-6 days). The SPSS16.0 was used to analyse the observational index. The t test, Chi-square test and Fisher exact test were used to compare between the two groups.

The results showed that the rate of incision infection after surgery was 7.69%, built-in retainer infection was 0, and the time of hospitalization was (30±3) days in the experimental group are all lower than the control group, that was 36.36%, 18.18% and (47±4)days, there were statistical significance(χ²=3.430, 1.976, t=7.949, P values were less than 0.05).

The burn patients with maxillofacial fracture have reduction of fracture and built-in retainer surgery after the shock and before the infection time(after injury 1-3 days), not only reduce the rate of infection but also realize taking food by mouth in early time, which can provide nutrition support and set up benign relationship, to better promote burn wound healing.
