ANNALI ITALIANI DI CHIRURGIA(2017)
Abstract
AIM: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.
MATERIALS OF STUDY: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.
RESULTS: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.
DISCUSSION:In literature is actually discussed the risks related to the presence of lower third molars during mandibular osteotomies.
CONCLUSIONS:Our study is designed to be helpful to the beginner surgeons during them first time approach to this kind of surgery.
