METHOD FOR SURGICAL APPROACH TO LOWER JAW EXPERIMENTALLY IN RABBIT

摘要

FIELD: medicine.;SUBSTANCE: method involves general anaesthesia, tissue dissection, lower jaw skeletisation, defect creation, and wound closure. The skin is incised in a projection of a lower edge of the lower jaw within the vascular segment at 5 mm from the edge of the lower jaw. The incision extends by blunt dissection towards the lower edge of the lower jaw with the facial vein and artery towards the mandibular angle; the lower edge of the lower jaw is skeletonised within the vascular segment. A blind vascular bed is formed within the vascular segment or at 1-5 mm anteriad from the vascular segment at an angle of 40-75° to the lower edge of the lower jaw in parallel with the mandibular canal; an implant made of the investigated material is placed into the bone bed until primarily stabilised.;EFFECT: method provides the minimum injuries accompanying creating the wound, reduces the risk of the incision wound damage by animals, enables performing the operation on both sides of the skeleton simultaneously, provides an adequate amount and quality of the bone tissue in the surgical area, reduces a risk of involving vital anatomical regions, and preserves the functional and anatomical integrity of the mastication muscles.;2 ex, 6 dwg
