["Quadrangular" Le Fort II osteotomy for hypoplasia of the midface. Apropos of 28 cases].

In 1971, Kufner described the "quadrangular" osteotomy of the midface, which he used to correct asymmetry in patients with recession of the midface and a normal nasal skeleton. We have used this method in 28 patients, 5 women and 23 men. The surgical technique is described and the indications, the approach and the stability of the postoperative results are discussed. The conclusion is that the "quadrangular" osteotomy is a very satisfactory method for the aesthetic and functional rehabilitation of a certain group of midfacial anomalies.
