[Application of a new vascular injection technique in the study of the infratemporal region].

The infra-temporal region (ITR) is an anatomically rich region thanks to its arterial and venous divisions and large nerve crossroads. It is also, as described by Robert et al". in a publication about the ITR, (22) "the hidden face of the manductory apparatus.

[Venous drainage and innervation of the maxillary sinus].

The maxillary sinus, or "Highmore's antrum", is a cavity of the facial structure buried in the body of the maxillary body joined to the nasal fossae with which it communicates via the maxillary ostium. The dissection of 25 maxillary sinuses has enabled us to study its venous drainage and innervation. The venous system is collected either by a single trunk, which is a continuation of the spheno-palatine vein, or by three venous plexus: the anterior and posterior pterygoid plexus, and the alveolar plexus.
