Abstract

Purpose

The use of Hybrid arch-bar systems which utilize bone support is a relatively recent development in the management of mandibular fractures with the potential to reduce surgical time. The purpose of this study was to compare the length of surgery time between Hybrid arch-bars and traditional Erich arch-bars in the treatment of mandibular fractures.

Methods

The author implemented a prospective randomized non-blinded study on consecutive subjects presenting with mandibular fractures to Grady Memorial Hospital. The primary predictor variable was the use of Hybrid arch-bars versus Erich arch-bars. The primary outcome variable was the length of surgery time. Secondary outcome variables include time to place the arch-bars and fracture healing. Univariable and multivariable statistics were computed with a p value of <0.05 being considered significant.

Results

Fifty patients were enrolled and completed the study. The mean length of surgery was 108 minutes in the Hybrid group and 117 minutes in the Erich arch-bar group (P=0.62). The mean time taken to place arch-bars was 14 and 37 minutes, in the Hybrid and Erich arch-bar group, respectively. (P<0.0001). There was no difference in fracture healing between the groups. (P=0.58)

Conclusion

Hybrid arch-bars, although reducing the time needed to place arch-bars when compared to traditional Erich arch-bars, do not appear to result in a reduction in the length of surgery time when treating isolated mandibular fractures.
