[Pre-implantation apposition grafts for edentuous anterior maxillary. Retrospective study of 36 patients].

INTRODUCTION: Apposition grafting is a method of choice for reconstruction of the anterior maxillary. The purpose of this work was to evaluate the success rate, the degree of bone resorption and the osteointegration of these grafts. MATERIAL AND METHODS: We reviewed retrospectively 36 cases of pre-maxillary bone apposition in patients operated from 1998 to 2002. Autografts were used for all patients. The harvesting site was parietal for 24 patients, intraoral for 8 and iliac for 4. RESULTS: There was two graft failures. The success rate was 94.5%. Partial resorption with effect on implantation was noted in 3 patients. Eighty implants were inserted successfully in 234 grafted sites with on average 2.4 implants per graft. Three implants were removed. Implant survival was 96.2%. DISCUSSION: This study demonstrated that the premaxillary apposition technique using autologous grafts provides sufficient bone volume to enable optimal implant insertion and stability.

[Stability of grafts and implants after bone grafting of the maxillary sinus. Retrospective analysis of 44 patients].

OBJECTIVES: We assessed the reliability of maxillary bone grafting and implant stability, comparing our results with reports in the literature. MATERIAL AND METHODS: This retrospective series included 44 patients who underwent maxillary sinus bone grafting between 1998 and 2002. An analogous graft was used for 31 patients and a combination autologous-bone substitute graft for 13. One hundred twelve dental implants were positioned at the grafting site (2.5 implants per graft). We assessed recipient site morbidity, bone graft integration and stability, and stability of the implants. RESULTS: Bone grafting was successful in 97.8% of patients. There was one failure. Two of the 112 implants failed. DISCUSSION: Our results are comparable with those in the literature. This study demonstrated the reliability of maxillary bone grafting with equivalent results using autologous bone and combination autologous bone-bone substitute.

[Reconstruction of complex tissue loss of the medial canthus].

The medial canthus is an anatomic and surgical entity. Reconstruction after cancerological resection is complex. The purpose of this article is to report a reconstruction technique for massive loss of tissue of the medial canthus which was applied in 2 patients with 2 years follow-up. Anatomic reconstruction was achieved. Each element of the canthus was restored: skin using Mustardé temporojugal and frontal flaps, conjunctive using a palatine mucosal graft, lacrimal canal using conjuctivo-rhinostomy, the medial canthal ligament using a fascia lata graft and transnasal canthopexia. Both patients developed an ectropion which required revision surgery. At 2 years, the functional outcome is good. Reconstruction allowed adapted social life and the cancer was controlled successfully.

[Reconstruction of complex loss of maxillary substance using a vascularized fibular flap after arteriovenous fistulization with a saphenous loop].

INTRODUCTION: When major loss of bone stock requires a vascularized transfer, the poor quality of the receiver vessels may require complementary lengthening of the vascular pedicle. This can be achieved with venous bypasses or by preparing the recipient site with a vascular loop. We have used this later approach successfully in a patent with major tissue loss involving the maxillary bone. CASE REPORT: A 39-year-old man presented total loss of the maxillary tissues due to a firearm wound. A free fibular flap was considered. Due to the limited length of the fibular pedicle, and the scar tissue in the area of the vascular anastomoses, reconstruction was performed in two phases: first preparation of the recipient site with a saphenous loop then fifteen days later transfer of the fibular flap. DISCUSSION: This technique is an alternative to venous bypass which increases the risk of postoperative thrombosis. The objectives of the vascular loop are to position the anastomoses in a healthy area and to achieve end-to-end anastomoses. This technique has been described basically for the treatment of post-traumatic tissue loss of the limbs, but can be applicable for the face, particularly after radiation.

[Anterolateral thigh free flap. Surgical technique].

The anterolateral thigh free flap is a cutaneous or fasciocutaneous flap vascularised by one or several perforating arteries arising from the descending branch of the lateral circonflex femoral artery. Venous drainage occurs via the perforators or a similar route to the deep femoral system or the femoral vein. This flap is commonly used in Asia (China, Japan) where for certain teams, it replaces the classical radial forearm flap or the rectus abdominis myocutaneous flap for the reconstruction of head and neck defects after tumor ablation. We briefly describe the anatomy and vascularization of this flap and present the harvesting technique as well as the properties of the flap.

[Dental agenesis. Results of a prospective study of 30 cases].

OBJECTIVE: We conducted a prospective study to determine the types of bone anomalies observed in different types of dental agenesia. PATIENTS AND METHOD: This prospective series included 30 patients who attended our pluridisciplinary clinic since 1988. There were 22 cases of non syndromal agenesia and 8 cases of syndromal agenesia. Patients consulted for a variety of reasons, no specific sign was found. The diagnosis was based on the panoramic x-ray and confirmed at the genetic consultation. RESULTS: Results were systemized by localization of the agenesia. In all cases, the height of the bone crest was preserved compared with the adjacent teeth. In the anterior part of the maxillary, the bone crest was thin showing a water drop aspect. In the posterior maxillary, there was a decrease in the subsinusal height due to invagination of the floor of the sinus. In the anterior part of the mandible, the crest had a knife blade aspect but no loss of height and in the posterior part, a preserved distance between the residual crest rim and the dental canal. DISCUSSION: In 60% of the solitary agenesias in the anterior part of the maxillary, augmentation was not required. A sinus graft was required in all cases involving the posterior maxillary. Multiple anterior or lateral agenesias were treated with a parietal graft.

[The facial artery-buccinator musculo-mucosal flap for reconstruction of the palate].

Since may 1999, 5 facial artery musculo-mucosal (FAMM) flaps have been used for mucosal reconstruction of the top of the mouth. The FAMM flap, first described by Pribaz in 1993 is a modification of the naso-labial cutaneous flap. The flap can be inferiorly based on the facial vessels (orthograde flow) or superiorly based (retrograde flow). It can easily reconstruct palate, alveolus and soft palate defects. The are of rotation has its pivot point inferiorly at the retromolar trigone, superiorly at the gingival labial sulcus. The FAMM flap has been used for 2 palatal fistula after facial blast injuries and 1 secondary cleft palate surgery. For the cleft palate surgery an Lefort 1 osteotomy with iliac crest graft was associated. All the flap but one survive with primary healing. One partial necrosis was noted but spontaneously healed secondarily. The FAMM flap is a reliable flap for mucosal reconstructions of the top of the mouth. The flap dissection is easy and the donor site morbidity is low.
