Objective: to develop on the skull and polymer embalmed preparations the projection of the triangles of the facial skull and infratemporal fossa and to study the topography of vascular-nervous structures within them.
Materials and methods. The study was performed on 40 corpses and 20 polymer embalmed specimens of the head and neck of adults aged 22 to 60 years. To determine the topography of vascular-nervous formations of the midface we selected new topographic landmarks: lateral facial, anterior maxillary, lateral maxillary, lateral infratemporal triangles.
Results. It is established that according to the standard points on the skull and polymer embalmed preparations it is possible to create a projection triangles: lateral facial, anterior maxillary, lateral maxillary, lateral infratemporal. The topography of the maxillary artery and its branches should be studied within the infratemporal lateral triangle. The topography of the facial artery, facial vein, branches of the trigeminal and facial nerves should be assessed within the lateral facial, anterior maxillary and lateral maxillary triangles.
Conclusions. The proposed projection of the triangles of the facial skull can be widely applied in practice of doctors of oral and maxillofacial surgeons for the planning of operative accesses to the structures of the midface.
