Evaluation of Efficacy of Slot Head Screw with Philips Head Screw in Maxillofacial Fixation - A Comparative Study
Abstract: Aim & Objective: The aim of this study was to compare the efficacy of Slot head screws and Philips head screws in maxillofacial fixation - a prospective case control study. Methods- This study was performed on 20 patients with clinical and radiological evidences of mandibular parasymphysis fractures randomly divided into 2 groups where Group A was case group, treated with open reduction and internal fixation using 2mm Titanium plates secured with Philips head screws whereas group B was control group, treated with open reduction and internal fixation using 2mm Titanium plates secured with slot head screws. Parameters assessed were time taken for loading of screws, tightening of screws, detachment of screw driver, total time taken for placement of screws, number of slippage of screwdriver, and iatrogenic damage to surrounding tissues. Results: It was seen that the time required for loading of screws, tightening of screws detachment from screw driver and placement of screws was significantly less in Group A than Group B. No significant difference was observed with respect to parameters like wound dehiscence and occlusion. Conclusion: It was concluded that Philips head screw performed significantly better than slot head screw in above evaluated areas as well as operating time and operator fatigue were found to be less with Philips head system than Slotted head system.
