The aim of our study is to demonstrate that the presence of upper wisdom teeth must be evaluated before and during Le Fort I osteotomy because attention must be focused to the disadvantages or facilitations of surgery depending on molar presence.
Our study has analyzed two groups, each one including 20 patients, 10 males and 10 females, with an age between 16-30 years. The first group was treated with le Fort I osteotomy leaving in situ the wisdom upper third molars. The second group was treated with Le Fort I osteotomy after the extraction of the wisdom upper third molars.
Group A: upper third molar avulsion, necessary in 5 cases, was the main reason for prolongation of surgical time. However, in group A, increased bleeding occurred in 3 cases, bone irregularities and bone interferences occurred in 2 cases, neurological injuries occurred in 2 cases, any complications occurred in 8 cases. Group B: the management of the hemorrhage resulting from the vascular injuries, occurred in 7 cases, was the main reason for prolongation of surgical time. However, in group B, bone irregularities and bone interferences occurred in 4 cases, neurological injuries occurred in 3 cases, any complication occurred in 6 cases.
In literature is actually discussed the risks related to the presence of lower third molars during mandibular osteotomies.
Our study is designed to be helpful to the beginner surgeons during them first time approach to this kind of surgery.

我们研究的目的是证明在Le Fort I型截骨术前和术中必须评估上颌智齿的存在情况，因为手术的利弊取决于磨牙的存在情况，必须予以关注。
我们的研究分析了两组，每组包括20名患者，10名男性和10名女性，年龄在16至30岁之间。第一组接受Le Fort I型截骨术，上颌第三磨牙保留原位。第二组在拔除上颌第三磨牙后接受Le Fort I型截骨术。
A组：5例需要拔除上颌第三磨牙，这是手术时间延长的主要原因。然而，在A组中，3例出现出血增加，2例出现骨不规则和骨干扰，2例出现神经损伤，8例未出现任何并发症。B组：7例因血管损伤导致出血的处理是手术时间延长的主要原因。然而，在B组中，4例出现骨不规则和骨干扰，3例出现神经损伤，6例未出现任何并发症。
目前文献中讨论了下颌截骨术中与下颌第三磨牙存在相关的风险。
我们的研究旨在帮助初涉此类手术的外科医生。
