Maxillary alveolar bone ridge width augmentation using the frame-shaped corticotomy expansion technique.

Maxillary alveolar ridge expansion performed by intercortical bone splitting is a seducing alternative surgical procedure for alveolar bone widening. The aim of this technique is to gain enough bone width to be able to place a dental implant simultaneously. This technique avoids a second surgical site for bone graft harvesting.

[Alveolar ridge augmentation with cortical osteotomies for dental implantation].

Cortical osteotomies allow alveolar ridge augmentation so as to place dental implants of adequate size, most often in one step. This technique is reliable and allows long-lasting prosthetic restoration, without need for a graft-harvesting site. We report an expansion technique, which combines various cortical alveolar osteotomies.

[Amniotic fluid embolism during curettage for a pregnancy arrest. Case report].

Amniotic fluid embolism is always a serious complication during the peripartum period. We report the case of an amniotic fluid embolism during curettage for a pregnancy arrest at 13 weeks. The diagnosis was confirmed by the presence of epithelial cells into the maternal blood.

[Maxillary ridge expansion for dental implant placement with alveolar corticotomy].

Unlabelled: Maxillary ridge transversal expansion is based on osseous plasticity obtained by corticotomy. It allows progressively for an adequate transversal intercortical diameter large enough to insert one or several dental implants. We present a pre-implant maxillary ridge transversal osseous expansion technique.

[The corrugator supercilii muscle. A review].

Corrugator supercilii is a facial, forehead and supra-orbital muscle. The frown glabellar wrinkles are mainly formed by repeated contractions of this muscle. These wrinkles will produce the picture of premature ageing even in a young person.

[Prosthetic rehabilitation with dental implant in cleft lip and palate: a ten-year retrospective study].

Introduction: Two problems need to be faced during cleft lip and palate surgical treatment to gain a functional and esthetic result: restoration of the maxillary bone defect and the missing lateral incisor tooth, which may be replaced by an implant. The aim of our study was to demonstrate that it is possible to successfully place a dental implant after obtaining adequate bone graft volume.

Patients And Method: 12 consecutively treated patients were studied, 7 with unilateral and 5 with bilateral clefts, mean age 21.

[Modified subcutaneous mastectomy. Apropos of 916 cases].

Modified subcutaneous mastectomy was described by one of us in 1968; its approach, the dissection of the gland, plastic reconstruction of shape and volume are completely different from the subcutaneous mastectomy performed by plastic surgeons. 3 different time periods were studied to explain clearly evolution in the technic and indications. During many years retrospective studies made it possible to build a procedure according to the new diagnostic means for infraclinical breast cancer and to the constant improving prosthetic material.

[mandibular reconstruction by free bone flaps with micro-anastomosis. Our current indications].

The frequency with which difficulties were encountered in the reconstruction of the continuity of the mandible led us to attempt to systematize our indications. Although grafts, composite pedicle flaps and prosthetic guides still have their appropriate applications. Local conditions are more and more frequently amenable to free flaps.

[Post-traumatic enophthalmos].

Based on 8 cases, the authors study the mechanisms involved in post-traumatic enophthalmos and demonstrate that they result from an increase in orbital volume. There are no grounds to suggest that the disappearance of orbital fat is involved.

[Experimental study of an axial vascularized pedicle flap induced in rats].

The authors report an experimental study about induced flaps in rats. The aim of this study is to determine that neoangiogenesis can be formed from surgically introduced pedicle. Two main groups were studied: in the first one the arteriovenous pedicle was be anastomased at its distal end, in the other, an arteriovenous loop was created microsurgically.

[Changes in the nasal pyramid in osteotomy of the maxilla].

The correction of dento-facial deformities with Lefort I osteotomy are always accompanied by changes in soft tissue and skeleton. But, in many cases there is also modification of the low floor of the nose and profile changes. This clinical experience has been confirmed in the Laboratory on cadavre experimentation.
