Abstract.
The aim of this study was to describe the microvascularization of the area of junction located between the integuments of the nasal ala and the respiratory mucosa. This study is part of an overall study on the microvascularization of the mucocutaneous junctions of the head. It was undertaken on histological or clarified sections of noses from fetuses, newborns and adults whose vascular system was injected with Indian ink agar. The mucocutaneous junction of the nose shows similarities with the mucocutaneous junction of the oral cavity. Under a well-defined avascular and thick epithelium lies a vascular papillary network with typical loops less high than in the lips. The angioarchitectonics of superficial and deep vascular reticular networks is similar to that of the lips but they are less dense.
