    Three-dimensional modeling of nasal septal deviation
    Seyhan, A; Ozaslan, U; Sir, E; Ozden, S
    Background: Some deviated nasal septa can never be straightened completely due to their 3-dimensional (3-D) nature. 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.

    A simplified use of septal extension graft to control nasal tip location
    Seyhan, A; Ozden, S; Ozaslan, U; Sir, E
    Background: For defining the shape and projection of the nasal tip, the bilateral and symmetric batten-type septal extension grafts proposed by Byrd and colleagues have drawbacks. The main problems are stiffness of the nasal tip and thickening of the septum in the nasal valve area. Methods: Since 1998, unilateral single-batten grafts, and more frequently, bilateral asymmetric batten grafts as compared with Byrd's bilateral symmetric application, have been used for 72 patients in our facility. Results: At the 6-month postoperative follow-up assessment, tip projection was found to be satisfactory in 61 patients. Less than desired projection occurred in three cases and overprojection in two cases. Nasal lobule deviation was evident in one patient. The loss of the columellar break point was evident in five cases. Conclusion: Unilateral or asymmetric bilateral batten grafts facilitate adjustment of the nasal tip intraoperatively. This technique results in a more pliable nasal tip in the horizontal plane. Construction of a three-layered cartilage in the nasal valve area is not needed, and the nasal airway is preserved. With this modification, a reliable and predictable nasal tip location is obtained with a minimum of graft usage.
