Median cleft of the upper lip (MCL) is a specific and rare entity on the spectrum of facial clefts. MCL have different clinical expressions and can be either isolated or part of multiple malformations. Confusion still exists regarding the explanation and classification of MCL; some cases have been reported in the literature, but no studies carried out a complete review of the literature.

Solitary fibrous tumor (SFT) is a rare etiology of progressive unilateral exophthalmia. The tumor is of mesenchymal origin and it is usually well defined. But recurrences can occur despite of complete surgical resection.

Introduction: The main morphological sequels of zygomatic bone fractures are lack of zygomatic projection and enopthalmia. They may be corrected by zygomatic osteotomy which is a difficult operation because of modified anatomic landmarks. Onlay bone or alloplastic grafts are preferred.

Bone wax or Horsley wax, which is used very frequently in bone surgery, is a non-absorbable mixture of beeswax (70%) and Vaseline. It permits the haemostasis of bone gaps by mechanical obstruction of bone pores containing blood capillaries. Complications due to this product are rare but sometimes quoted in literature.

Introduction: Low intensity pulsed ultrasound (LIPUS) is one of the methods used to stimulate bone regeneration. This technique is still not well known or explained. The expression of several proteins (VEGF, IL-8, FGF-β, IL-1 β) or genes (ALP and OP) was increased after being exposed to weak ultrasounds, whereas IL-6 and TNF-α were not affected.

Introduction: The management of post-traumatic deformity in the midface region poses challenges for the maxillofacial surgeon. Ensuring symmetry after zygomatic osteotomy can be difficult and precise positioning of the osteotomised bony fragments requires careful treatment planning. It may be necessary to use a coronal flap to allow the surgeon to compare the contralateral zygomatic bone to allow symmetrical reduction.

Introduction: Our aim was to study the reliability of sagittal split osteotomy and Le Fort I osteotomy respectively, and to try to judge objectively the impact of their order for the final result of bimaxillary osteotomy.

Patients And Method: Fifty patients were included. For each we calculated the errors generated by sagittal split osteotomies on one hand and Le Fort I osteotomy on the other hand, by performing a peroperative splint after each osteotomy.

Introduction: The aim of this study was to assess piezosurgical sagittal split osteotomy with peroperative inter maxillary fixation.

Material And Method: We studied 25 bimaxillary osteotomies, 50 sagittal split osteotomies performed with this technique. It included both maxillomandibular fixation during all the split osteotomy and performing split osteotomy in five steps.

Background: Although patient-controlled analgesia' (PCA) use has been reported in oral and maxillofacial surgery,(8) it has not been evaluated for use in orthognathic surgery. In this study, we evaluated the relationship between age, gender, and preoperative anxiety and postoperative morphine intake after orthognathic surgery in the PCA environment.

Study Design: Fifty-one patients (34 female, 17 male) underwent orthognathic surgery.

Objective: To describe the different myoplasty techniques that could be used for limited commissural reconstruction.

Methods: Twelve cases of congenital macrostomia are reported, with different cleft lengths and termination sites. For each case, an orbicular myoplasty was performed, and in the case of extension to the area of the tragus or tonsillar pillars, a masseteric myoplasty or pharyngoplasty was performed.

Testicular choriocarcinoma is a highly malignant germ cell neoplasm, which metastasises to lungs, and brain. Spread to the skin, however, is rare, with only 11 cases reported to our knowledge. This is the second reported case of a skin metastasis of choriocarcinoma to the head and neck, and the third in which a cutaneous metastasis was the first finding at initial presentation.

Background: We performed the first human partial face allograft on November 27, 2005. Here we report outcomes up to 18 months after transplantation.

Methods: The postsurgical induction immunosuppression protocol included thymoglobulins combined with tacrolimus, mycophenolate mofetil, and prednisone.

Background: Removal of orbital tumors is a difficult problem. The goal of this study was to evaluate the advantages of the craniofacial approach to remove such tumors and to evaluate ultrasonic bone cutting during the procedure.

Method: The authors reviewed their experience with 57 tumors of the posterior cavity using lateral craniofacial and frontal transsinus approaches.

The first facial allograft was realised in Amiens 2005 November 27th. Breaking the technical limits of the so called possible and in appearance transgressing some cultural forbidden in organ transplantation, this resolutely innovative intervention open more than new perspective in the surgery of the reconstruction after disfigurement, but also a wide field of scientific investigations about dynamic and meaning of the facial function. Obviously, it also deals with numerous ethical and medical problems.

Ultrasound osteotomy is a new surgical technique used in dentistry to section hard tissues without damaging adjacent soft tissues. It was hypothesized that this could also be useful in craniofacial and orthognathic surgery. An ultrasonic device was employed in the following craniofacial surgical procedures: 144 Le Fort I osteotomies, 140 palatal expansions after Le Fort I osteotomies and 140 bilateral sagittal osteotomies; 2 Le Fort III osteotomies for treatment of Crouzon syndrome in two patients; 12 cases of unicortical calvarial bone grafting; removal of superior orbital roof in 25 cases of craniofaciostenosis; removal of external wall of the orbit in 10 cases of orbital cavity tumour; removal of anterior and posterior walls of the frontal sinuses in four cases of orbital cavity tumour.

Introduction: Delaire's architectural analysis is a tool used in the maxillofacial field. Its use requires identifying landmarks teleradiographically in order to map appropriate lines dependent on these points. We studied the elasticity of the analysis.

Introduction: Piezosurgery is a new surgical technique used in dentistry to section hard tissues without damaging adjacent soft tissues. We hypothesized that such a device could also be useful in craniofacial and orthognathic surgery.

Material And Method: An ultrasonic device (Mectron) was employed in different craniofacial surgical procedures: a) to perform 144 Le Fort I osteotomies, 140 palatal expansions after Le Fort I osteotomies, and 134 bilateral sagittal osteotomies; b) to perform a Le Fort III osteotomy for treatment of Crouzon syndrome in 2 patients; c) to perform 5 segmental osteotomies and 3 osteotomies of the inferior edge of the mandible for facial asymmetry; d) to perform 12 cases of unicortical calvarial bone grafting; e) to remove the superior orbital roof in 20 cases of craniofaciostenosis and the frontal bone in 5 cases; f) to remove the external wall of the orbit or the anterior and posterior wall of the frontal sinuses in 10 cases of orbital cavity tumors; g) to approach the skull base through the frontal sinuses in 4 cases.

Introduction: Ultrasonic bone cutting is a new surgical technique used in dentistry to section hard tissues without damaging adjacent soft tissues. We hypothesized that such a device could also be useful in craniofacial surgery, particularly during the removal of the superior orbital roof during craniofaciostenosis surgery.

Materials And Methods: An ultrasonic device was employed in different craniofacial surgical procedures: 1.
