Based on a study of models and clinical cases, a basic classification and treatment strategy was proposed for 3-D septal deviations. METHODS: Basic types of 3-D septal L struts were crafted from pieces of thick plastic sheeting. By a carefully placed through-and-through incision in the angle area and overlapping the resultant segments, the models became 2 dimensional (2-D). We used this technique intraoperatively, in some cases resecting the overlapping area of septal tissue, along with a septal extension graft, in 11 patients who were followed up for more than 6 months. RESULTS: External nasal deviation due to a deviated septum was obvious in 5 cases, and all were relieved postoperatively. Preoperative breathing difficulties were improved in 7 of 8 patients. CONCLUSION: Correction of 3-D septal L deformity can be successfully performed by constructing 2-D L struts by making a full-thickness incision of the angle area and then overlapping the segments. This approach is especially beneficial in those having a septal extension graft that need a perfectly straight caudal septum upon which to fix the extension graft. © 2008 Lippincott Williams & Wilkins, Inc.EnglishAdultFemaleHumansMaleNasal SeptumRhinoplastyarticledyspneafemalefollow uphumanintraoperative periodmalemathematical modelnose malformationnose reconstructionnose septumpostoperative periodpreoperative periodpriority journalthree dimensional imagingArticle10.1097/SAP.0b013e31805b0517
