Accuracy evaluation of CAD/CAM generated splints in orthognathic surgery: a cadaveric study.

Introduction: To evaluate the accuracy of CAD/CAM generated splints in orthognathic surgery by comparing planned versus actual post-operative 3D images.

Methods: Specific planning software (SimPlant(®) OMS Standalone 14.0) was used to perform a 3D virtual Le Fort I osteotomy in 10 fresh human cadaver heads.

Completion of nonreducible Le Fort fractures by Le Fort I osteotomy: sometimes an inevitable choice to avoid postoperative malocclusion.

The aim of this study was to prospectively evaluate the use of a simultaneous Le Fort I osteotomy for completion of nonreducible Le Fort fractures. We analyzed the clinical and radiological data of 44 patients with Le Fort fractures, 9 of whom presented with a nonreducible type. Seven patients with an incomplete Le Fort I fracture had a contralateral Le Fort I osteotomy, and 2 patients with an incomplete Le Fort III fracture had a true bilateral Le Fort I-type osteotomy.

Is age of the patient an independent predictor influencing the management of cranio-maxillo-facial trauma? A retrospective study of 308 patients.

Objective: To determine whether patient age is an independent predictor of indication for surgical treatment, realization of surgical procedure, and care management modality.

Study Design: We analyzed data of 308 patients with facial fractures. Patients were classified into four age groups: (1) 17 to 40 years old; (2) 41 to 64 years old; (3) 65 to 80 years old; (4) more than 81 years old.

Pseudo-Brown syndrome: a potential ophthalmologic sequela after a transcaruncular-transconjunctival approach for orbital fracture repair.

Purpose: To prospectively assess the incidence of orthoptic anomalies and, more specifically, the possible development of pseudo-Brown syndrome related to inferior oblique muscle (IO) myotomy after the transcaruncular-transconjunctival approach for orbital fracture repair and its effect on the possible development of annoying diplopia.

Patients And Methods: We analyzed the clinical data from 14 patients with severe isolated medial wall or combined medial wall/floor fractures treated using titanium meshes placed using a transcaruncular-transconjunctival approach. All patients were assessed with a pre- and postoperative ophthalmologic examination using the following methods: prisms and alternate cover test in all 9 gaze directions, Hess-Weiss coordimetry, Maddox rod screen testing, and Harms wall deviometry.

Computational area measurement of orbital floor fractures: reliability, accuracy and rapidity.

Objective: To evaluate the reliability, accuracy and rapidity of a specific computational method for assessing the orbital floor fracture area on a CT scan.

Method: A computer assessment of the area of the fracture, as well as that of the total orbital floor, was determined on CT scans taken from ten patients. The ratio of the fracture's area to the orbital floor area was also calculated.
