The use of Carrol-Girrard T -bar screw for reduction of zygomatico-maxillary fracture by two different orbital approaches (A randomized controlled clinical trial)

Abstract

Aim: This study aimed to evaluate two different approaches; subtarsal and transconjunctival approaches for reduction and fixation of ZMC fractures with the aid of Carrol-Girrard T -bar screw regarding the accessibility to the surgical site, adequacy of reduction and incidence of postoperative complications. Materials and Method: twenty patients suffering from zygomatico- maxillary complex fracture (ZMC) were selected conveniently and randomly divided into two equal groups. Transconjunctival incision was used for accessing the fractured ZMC in the study group, while the subtarsal approach was used in the control group. The reduction and fixation in both groups was achieved using the Carrol-Girrard T bar screw. Results: No statistically significant difference was seen among both groups in terms of postoperative pain, edema, ocular or sensory complications and adequacy of ZMC reduction. Conclusion: Transconjunctival incision for the exposure of the infraorbital rim and orbital floor combined with the use of Carroll-Girrard T- bar screw for the reduction and management of ZMC fracture is a convenient approach with minimal reported intra or postoperative complications.
