BACKGROUND Severe maxillary hypoplasia in cleft patients is caused by a combination of pathogenic and iatrogenic factors. In this work, the authors investigated anatomical deficiencies in dentition for predicting Le Fort I maxillary advancement surgery for severe maxillary hypoplasia in cleft patients. METHODS Cleft lip-cleft palate and cleft palate patients older than 14 years of age were re...

For accurate superior or posterior repositioning of the maxilla in Le Fort I osteotomy, bone removal around the descending palatine artery (DPA) and maxillary tuberosity is required. Because the most common site of hemorrhage in the Le Fort I osteotomy is the posterior maxilla, this bone removal provides surgeons to surgical frustration of DPA injury. When the DPA is injured during the bone rem...

The purpose of this study was to examine the changes in temporomandibular joint (TMJ) morphology and clinical symptoms after intraoral vertical ramus osteotomy (IVRO) with and without a Le Fort I osteotomy. Of 50 Japanese patients with mandibular prognathism with mandibular and bimaxillary asymmetry, 25 underwent IVRO and 25 underwent IVRO in combination with a Le Fort I osteotomy. The TMJ symp...

The objectives of this study are to assess the velopharyngeal dimensions using cephalometric variables of the nasopharynx and oropharynx as well as to compare the Le Fort I osteotomy technique to Zisser's anterior maxillary osteotomy technique based on patients' outcomes within early and late postoperative follow-ups. 15 patients with severe maxillary deficiency treated with Le Fort I osteotomy...

BACKGROUND Fractures of mid-face were first described by Le Fort and are classified into three categories - Le Fort I, Le Fort II and Le Fort III. The pterygoid processes of the sphenoid bone are fractured in all the three categories of Le Fort fractures as the sphenoid bone connects the cranium vault to the facial bones. Fractures of the pterygoid processes without associated Le Fort fractures...

Objective The aim of this study is to quantitatively evaluate the stability of the skeletal and dental widths using cone-beam computed tomography (CBCT) after segmental Le Fort I osteotomy in adult patients with skeletal Class III malocclusion requiring maxillary expansion. Methods In total, 25 and 36 patients with skeletal Class III malocclusion underwent Le Fort I osteotomy (control group) ...

OBJECTIVE The purpose of this study was to evaluate the horizontal changes in the condylar head with bent plate fixation after sagittal split ramus osteotomy (SSRO) with and without a Le Fort I osteotomy. STUDY DESIGN Of 47 Japanese patients with mandibular prognathism, 24 underwent SSRO and 23 underwent SSRO in combination with a Le Fort I osteotomy. A 3-5-mm gap was made between the proxima...

BACKGROUND The amount of postoperative maxillary relapse of two different bone graft materials after Le Fort I osteotomy were compared in this study. OBJECTIVES The aim of this study is to compare postoperative maxillary relapse rates using heterologous and autologous graft materials after Le Fort I osteotomy. MATERIAL AND METHODS A total of 80 patients who had developmental malocclusion we...

OBJECTIVE Abnormalities of the midface and maxilla are frequently corrected using Le Fort I surgery. This osteotomy passes near the apices of the maxillary teeth, severing the blood vessels and nerves supplying the teeth. The aim of this review was to determine the effect of Le Fort I osteotomy on pulpal vascularity and neurosensory response. DATA SOURCES A systematic search of the literature...

Severe midface hypoplasia in patients with various craniofacial anomalies can be corrected with Le Fort III or monobloc advancement. Often additional corrective orthognathic surgery is indicated to achieve Class I occlusion and a normal inter-jaw relationship. This study evaluated the incidence of, and the surgical indications for, secondary orthognathic surgery following Le Fort III/monobloc a...
