A study of the vascularization of the auricle by dissection and diaphanization.

The vascularization of the auricle is poorly documented, despite the developments in auriculotherapy and reconstructive surgery. The aim of this study was to describe its arterial distribution using two techniques: diaphanization and anatomical dissection. The study was conducted after intravascular injection of eight diaphanized auricles and ten that were dissected.

Gradual and safe technique for sinus floor elevation using trephines and osteotomes with stops: a cadaveric anatomic study.

Objective: The aim of this study was to develop a new technique for maxillary sinus floor elevation through the crestal approach, using trephines and osteotomes with stops, and to assess the risk of sinus membrane lesion.

Study Design: The study was performed on 30 heads removed from fresh nonpreserved cadavers with subsinus bone height >or=5 mm. The anatomic specimens were sectioned axially on a plane passing 1 cm below the infraorbital foramen, to be able to see and film the sinus floor covered by the membrane.
