Efficacy of Transoral Versus Transbuccal Technique for Fixation of Mandibular Angle Fracture

In transoral technique approach inferior alveolar nerve block and buccal nerve block will be given by 2% xylocaine with 1:100000 adrenaline. Incision will be made with surgical blade no 15 from gingival crevices of molars to ascending ramus. Fracture segments will be reduced alongwith MMF. A 5-hole 2mm miniplate with 2 holes anterior and 2 holes posterior to fracture line will be screwed to external oblique ridge and MMF will be removed and incision line will be closed.

In transbuccal technique inferior alveolar nerve block and buccal nerve block will be given by 2% xylocaine with 1:100000 adrenaline. Incision will be made with surgical blade no 15 from gingival crevices of molars to ascending ramus. Fracture segments will be reduced alongwith MMF. extraorally a stab incision will be made with scalpel blade parallel to relaxed resting skin tension lines through which the cannula with a trocar will be inserted through facial tissue down to bone. Transbuccal instrument system will cionsist of transbuccal guide, mountable retractor, drill sleeve, drill guide, and 2mm drill bit. A 2mm titanium miniplate will be placed along buccal cortex and screwed through trocar system. MMF will be removed and incision line closed
