An Oblique Columellar Artery Variant
A variant of the columellar artery (CoA), also known as the nasal septal branch of the superior labial artery of the facial artery, and its unusual direct anastomosis with the right infraorbital artery were identified in a cadaveric dissection. Numerous variants and distribution patterns of the CoA...

Sumario: | A variant of the columellar artery (CoA), also known as the nasal septal branch of the superior labial artery of the facial artery, and its unusual direct anastomosis with the right infraorbital artery were identified in a cadaveric dissection. Numerous variants and distribution patterns of the CoA have been described in the literature. However, an oblique and a third CoA variant that anastomoses with the contralateral infraorbital artery has never been reported or depicted. We highlight the significance of a preprocedural vascular examination of the perioral region for optimal functional and esthetic outcome by presenting this unique case. This CoA variant should be known by surgeons performing invasive surgical techniques in the columellar region. |
