| Popis: | Background The lag time between injury and treatment (LTIT) plays an important role in reduction of complications in mandibular fractures. The aim of this study was to measure the effect of LTIT on recovery of the inferior alveolar nerve (IAN) neurosensory disturbances (NSDs) following surgical management of mandibular body fractures. Methods This was a prospective cohort study. Patients who had a unilateral mandibular body fracture with paresthesia were studied. Paresthesia was evaluated by 2-point discrimination (TPD) test, brush stroke test and self-reporting before and 6 months after the surgical procedure. Results Forty-five patients were studied. There was a correlation between LTIT and TPD test result and self-reported paresthesia at 6 months, postoperatively (P = 0.001). Fifteen patients (33.3%) had complete improvement in NSD 6 months after treatments (group 1) and 30 patients (group 2) had hyposthesia (N = 17, 37.77%) and paresthesia (N = 13, 28.88%). There was a significant difference in LTIT between groups 1 and 2 at 6 months postoperatively (P = 0.001). Cox regression model demonstrated the hazard ratio increased significantly for self-reported NSD when treatment was done 10 days after trauma (P = 0.001, confidence level = 95%). Conclusion It seems that conduction of open reduction with internal rigid fixation shortly after mandibular fracture may shorten the recovery time of NSDs of the IAN following mandibular body fractures. |
