The nasal base para-alar region has been recognized as an important region for overall facial assessment. 1 Epker B.N. The Skeletal Nasal Base.

A technique for three-dimensional cephalometric analysis as an aid in evaluating changes in the crainofacial skeleton. Angle Orthod. 1999; 69: 345 PubMed Google Scholar Although the evaluation of this region is well established, surgical correction for this deficiency to improve the regional aesthetics is mainly by para-alar augmentation procedures. Autologous bone graft and alloplastic onlay are the mainstays of such treatments. Le Fort I osteotomy for advancement is often believed to be helpful for aesthetic improvement for such para-alar deficiencies. Very few articles have illustrated any practical regional osteotomy techniques that have gained wide popularity. Here we describe a new surgical technique for para-alar augmentation in which the pyriform rims are outfractured anterolaterally and maintained with a free interposition bone graft.
