RESUMEN
The aim of this prospective study was to analyse if a delay in the time from injury to definitive surgical intervention of open reduction and internal fixation (ORIF) of compound mandibular fractures predisposed to an increase in postoperative infectious complications. ORIF beyond 72 hours from injury was considered to be delayed intervention. Postoperative surgical site infections (SSI) and non-infectious complications (NIC) were recorded. The Mann-Whitney U test was used to compare the delay in ORIF with SSI. The chi squared test/Fisher's exact test was used to find the association of the infectious complication status with predetermined risk factors. Eighty-three patients underwent a delayed ORIF with a median (range) of 8 (4-19) days. SSI was documented in eight patients (9.6%) and could be managed as outpatient medical and surgical intervention. Two patients needed repeat surgical intervention due to non-union of the fracture. The median (range) time to ORIF was 6.5 (5-12) days in patients who developed SSI; the Mann-Whitney U test did not show a statistically significant association between delayed ORIF and SSI (p = 0.7). The univariate analysis did not establish a significant relationship between SSI and predetermined risk factors. The delay to definitive surgical intervention was not observed to be an independent attributing factor in postoperative infectious complications of compound mandibular fractures.
