Open reduction and internal fixation of mandibular condyle fractures using AUTOFIX 2.0® cannulated compression screw system: A technical innovation with intraoperative CT-scan.

Condylar process fractures remain a matter of ongoing controversy in maxillofacial surgery because of variety of opinions and proposed treatment modalities offered in the literature. The trend is toward open reduction and internal fixation (ORIF) whenever there is displacement or dislocation combined with unstable occlusal conditions. The fundamental treatment goals are anatomical fixation and early return to function.

Topographic superficial craniectomy for invasive scalp carcinoma.

The management of non-melanoma skin cancer of the scalp that invades the deep structures can be challenging. An operative technique of topographic superficial craniectomy using a piezoelectric instrument (Piezosurgery (Mectron S.p.

Chromophore reconstruction at depth in bilayered media: a method for quantification.

We report a method for deriving the absolute value of absorption coefficients at depth in bilayered media. The method was simplified from that of time-resolved diffuse optical tomography (TR-DOT) into one dimension to validate and set up the main parameters with the help of simulations, and to test it in an easy preclinical model. The method was applied to buried flaps as used in reconstructive surgery, and absolute chromophore concentrations in the flap and in the upper (skin and fat) layer were derived.

Replantation of a lip thrown in the bin.

Management of soft tissue avulsion after facial bites could be challenging in some situation. We presented the case of a 32 years old men suffering from a full thickness avulsion of the left lower lip and cheek after a dog bite. Even if the lip fragment was initially put on the bin, a microvascular replantation was performed.

Noninvasive Monitoring of Deep Tissue Oxygenation in Buried Flaps by Time-Resolved Near-Infrared Spectroscopy in Pigs.

Background: Flap monitoring in reconstructive surgery is particularly important because flap failure is a dramatic event for the patient and for the medical team. Noninvasive deep tissue oxygenation monitoring is a challenge. The aim of this experimental study was to assess the performance of time-resolved near-infrared spectroscopy compared with continuous-wave near-infrared spectroscopy and with invasive oxygen partial pressure measurement in pigs.

Distinction between arterial and venous occlusion with tissue oxygen pressure in a porcine fascio-cutaneous flap model.

Background: In recent years, many devices have been developed to monitor free flaps. The Licox probe, which measures tissue oxygen pressure (PtO ), is one of the available devices. Our aim was to demonstrate that PtO could distinguish arterial from venous occlusion in a porcine fascio-cutaneous flap model.

Improvement in accuracy of maxillary repositioning of Le Fort I osteotomy with Orthopilot™ Navigation System: evaluation of 30 patients.

Traditional model surgery with facebow transfer is not very accurate. We aimed to demonstrate that the Orthopilot™ Navigation System improves the accuracy of maxillary repositioning during Le Fort I osteotomy. Thirty patients underwent Le Fort I osteotomy alone or associated to sagittal split osteotomy.

Quantification of the inaccuracy of conventional articulator model surgery in Le Fort 1 osteotomy: evaluation of 30 patients controlled by the Orthopilot navigation system.

Occlusal splints are commonly used to position the maxilla during traditional orthognathic surgery. We aimed to quantify the inaccuracy of the maxillary positioning (in three dimensions) in traditional model surgery with the Orthopilot navigation system. Thirty Le Fort I osteotomies were made using a standard technique.

Learning condyle repositioning during orthognathic surgery with a surgical navigation system.

Condyle repositioning during bilateral sagittal splint osteotomy (BSSO) is a challenging step for the inexperienced surgeon. We aimed to demonstrate the benefit of navigation for learning the condyle repositioning. We treated 100 patients who underwent a BSSO.

Porcine abdominal cutaneous flap model: A simple and reliable method.

The increase of reconstructive microsurgery procedures leads to the development of various technologies. Before being validated in human clinical studies, these technologies and devices need to be validated on animal models. We present a simple, reliable and reproducible model of a cutaneous flap in pigs.

Nasal glial heterotopia or congenital hemangioma? A case report.

Nasal glial heterotopia (NGH) is a rare benign tumor of the median line. We describe the case of a child presenting a lateral nasal mass. The characteristics of the prenatal ultrasound and the postnatal clinical examination argued in favor of a congenital hemangioma (CH).
