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.

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.

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.
