Blandin is remembered today for his pioneer work in rhinoplasty and septoplasty. He is credited with coining the term autoplastie (autoplasty) to describe skin taken from same patient for grafting purposes.
He provided an early description of the anterior lingual glands, which are mixed glands of the tongue. These glands are sometimes referred to as Blandin's glands. His best known written work is an atlas of anatomy and surgery called Traité d'anatomie topographique.
