Although the different techniques and instruments described for lateral osteotomies date back decades, the literature on deciding the position of lateral osteotomies between the sides is limited. In general, the position of lateral osteotomies is decided by frontal view and palpation, but this is not always easy, especially in minimally deviated noses.
The SELF algorithm, which includes 4 developmentally related parameters, was used to decide the position and number of lateral osteotomies. Parameters of the SELF algorithm are septal position in nasal floor, external alar length, lateral pyramidal length and frontal pyramidal deviation's starting side. After considering and evaluating these parameters, either double lateral or high lateral osteotomy was performed on the side where the bony wall was considered to be longer.
Out of 521 patients whose lateral osteotomy level was decided by applying the SELF algorithm, 493 were female, and 28 were male. The ages of the patients ranged from 18 to 59 years. Based on the SELF algorithm, 401 double lateral and 85 high lateral osteotomies were performed on the side with the longest anterior-posterior distance of the bony pyramid. No serious complications, either functionally or aesthetically, were encountered related to lateral osteotomies performed based on the SELF algorithm.
There is a relationship between the position of the septum at the nasal floor, external alar length, lateral pyramidal projection and frontal deviation, as the tissues in the nose are shaped in relation to each other during development. The SELF algorithm based on these parameters can provide assistance to the surgeon in terms of selecting the position and number of lateral osteotomies, especially in minimally deviated noses.

尽管用于侧向截骨术的不同技术和器械可以追溯到几十年前，但关于确定侧向截骨术位置的文献却很有限。一般来说，侧向截骨术的位置是通过正视图和触诊来决定的，但这并不总是容易的，尤其是在轻度偏斜的鼻子中。
SELF 算法包括 4 个与发育相关的参数，用于确定侧向截骨术的位置和数量。SELF 算法的参数包括鼻底鼻中隔位置、外鼻翼长度、侧锥形长度和额状锥形偏离起始侧。在考虑和评估这些参数后，在被认为骨性壁较长的一侧进行双侧或高位侧向截骨术。
在应用 SELF 算法确定侧骨切开术水平的 521 例患者中，493 例为女性，28 例为男性。患者年龄为 18 至 59 岁。根据 SELF 算法，在骨性锥体长轴最长的一侧进行了 401 例双侧和 85 例高位侧向截骨术。根据 SELF 算法进行的侧向截骨术没有出现任何与功能或美学相关的严重并发症。
在鼻部，鼻中隔在鼻底的位置、外鼻翼长度、侧锥形突出和额状偏斜之间存在一定的关系，因为在发育过程中，鼻部的组织是相互关联的。基于这些参数的 SELF 算法可以为外科医生选择侧向截骨术的位置和数量提供帮助，特别是在轻度偏斜的鼻子中。
