“…During Le Fort I osteotomies, pterygomaxillary separation leads to damage to the descending palatine artery and pterygoid venous plexus. A tomodensitometric study to measure the position of the maxillary artery in relation to pterygomaxillary junction shows that there is a risk of injuring the artery around 20 mm above the inferior extremity of the pterygomaxillary junction [7]. Thus, to avoid bleeding complications during or after surgery, care is needed when performing pterygomaxillary separation.…”

A case of delayed epistaxis from the mucosa behind the right side of the inferior nasal mucosa 11 days after orthognathic surgery by Le Fort I osteotomy is presented. The patient was a 31-year-old man who underwent orthognathic surgery under general anesthesia. No abnormal findings were found during or after the operation. The patient was discharged from the hospital 10 days postoperatively. However, bleeding from the right nasal cavity occurred suddenly on the night after discharge, and he presented to our hospital again. The epistaxis was stopped once by nasal packing containing 0.001% epinephrine and systemic infusion of carbazochrome sulfonic acid and tranexamic acid. However, when the nasal packing was removed the next day, right nasal epistaxis was observed again. Curvature of the nasal septum and thickening of the inferior turbinate mucosa were seen on inspection; although, no active bleeding point was identified. Decreased nasal mucosa thickening and bleeding were observed after nasal packing containing 0.02% epinephrine. When the inside of the nasal cavity was observed endoscopically, an approximately 2 mm laceration was found in the mucosa behind the side wall of the right inferior nasal mucosa, and bleeding from the same part was confirmed. After endoscopic cauterization for hemostasis of the nasal mucosa, no rebleeding was observed. Although delayed epistaxis after Le Fort I osteotomy are often performed CT angiography to confirm the bleeding site, endoscopic cauterization would be primarily useful because of less invasiveness.

“…Bendrihem and Vacher performed a tomodensitometric study to measure the position of maxillary artery in relation to pterygomaxillary junction. They concluded that there is a risk of injuring the maxillary artery 18 mm above the inferior extremity of the pterygomaxillary junction [5]. It is to say how much we are close when performing pterygomaxillary separation.…”

Introduction: When performing a Le Fort 1 osteotomy, there is always a risk of injuring the internal maxillary artery or one of its branches. This diagnosis should be considered when confronted to recurrent or massive epistaxis following surgery.Case presentation: The authors present a case of a life-threatening, delayed and massive epistaxis caused by a ruptured pseudoaneuvrysm of the right sphenopalatine artery as a post-operative complication of a Le Fort I osteotomy successfully managed by anterior and posterior nasal packing.Conclusion: Despite its simplicity and attested reliability, Le Fort I osteotomy is not completely free of complications.

“…The main functions of IkB protein are: prevent NF-kB from transferring into the nucleus; prevent NF-kB from specifically binding to DNA [ 19 ]; Gradually dissociate the NF-KB DNA complex. The IKK complex is composed of three subunits a, β and γ, all of which have similar structural characteristics and high homology [ 20 ]. IKKα and IKKβ play an important role in the phosphorylation of IxB specific sites.…”

In recent years, many studies have found that mechanical tension can activiate NF-kB signal pathway and NF-kB plays an important role in the process of osteogenesis. However, it is still unclear whether this process exists in the anterior palatal suture expansion. In this paper, we mainly studied the effect of intraperitoneal injection of PDTC on the NF-kB signaling pathway and osteogenesis index of the anterior palatal suture expansion model in young adult rats. The expansion model is grouped and established: 45 male 8-week-old Sprague-Dawley rats were randomly divided into three groups, an expansion only (EO) group, an expansion plus PDTC (PE) group, and a control group. The results revealed that PDTC inhibited the activity of NF-kB signaling pathway and promote one morphogenetic protein 2 (BMP-2), steocalatin (OCN) expression. Compared with the control group, the optical density (OD) value of BMP in the EO group and PE group rats increased significantly from the first day to the seventh day, and the difference was statistically significant (P<0.05). After 6.0Gy irradiation, PDTC administration group could slightly increase the total SOD level in the liver and serum of rats, and reduce the MDA level in the liver and serum, especially the effect of 60mg/kg and 90mg/kg was the most obvious.

Radiologic anatomy of the maxillary artery in the pterygopalatine area applied to Le Fort 1 osteotomies

Abstract: According to our results, the height of the PM junction is less than 14 mm and during the PM disjunction there is a risk of injuring the maxillary artery 18 mm above the inferior extremity of the PM junction.
