Traumatic pseudoaneurysm of floor of mouth treated with selective embolization: a case report.

False aneurysms may be caused by trauma to the floor of the mouth from surgical procedures. The condition is hazardous because of the potential for airway obstruction from hematoma. A case of pseudoaneurysm of the facial artery occurring in the floor of the mouth is described. Treatment with superselective percutaneous angiographic embolization is a novel and efficient alternative for dealing with aneurysms arising in this region, with low morbidity.

Alveolar bone grafting in unilateral complete cleft lip and palate patients.

Autogenous bone graft of an alveolar cleft area has the following advantages: (1) assistance in the closure of buccoalveolar oronasal fistula; (2) provision of bony support for unerupted teeth and teeth adjacent to the cleft; (3) formation of a continuous alveolar ridge to facilitate orthodontic correction of malocclusion; (4) supporting the nostril floor and alar base to improve nasal aesthetics. It has been well accepted in most craniofacial centers as routine procedure in cleft lip and palate rehabilitation. A new surgical technique for alveolar bone grafting has been introduced to the Chang Gung Craniofacial Center since July 1991. It provided a good exposure of the alveolar cleft, primary closure of the fistula and adequate volume of bone graft. A review of 27 consecutive alveolar bone grafting procedures performed in unilateral cleft lip and palate patients from July 1991 to June 1992 was presented. Patients have been followed up for at least 6 months. The alveolar bone graft was evaluated clinically and radiologically at one week, six months and one year after the surgery. The preliminary results indicated that the new surgical technique produced less chance of recurrent fistula, good postoperative gingival height, and improvement of nasal aesthetics. Based on the results of this new study we strongly advocate the use of this new surgical technique.

[Osteotomy of the median tubercule as a consequence of bilateral complete labio-maxillo-palatal cleft].

In the bilateral total labio-maxillary cleft the premaxilla is sometimes very protrusive at the completion of facial growth. This kind of malposition cannot be treated by orthodontics. Surgical repositioning of the premaxilla with simultaneous bilateral alveolar maxillary bone graft is done before the revision of lip and nose. Its goal is the reconstruction of a solid and harmonious dental and maxillary arch, closure of bucconasal fistulas, improvement of facial profile by closure of nasolabial angle. The authors describe the operation technique and illustrate it by two cases.

The importance of restorative margin placement to the biologic width and periodontal health. Part II.

Part I of this article presented the rationale for the use of the crown-lengthening procedure prior to final prosthetic or restorative treatment. The primary objective of the procedure is the attainment of a periodontal biologic width, free of any invasive restorative dentistry, circumferentially around the tooth. Part II of this article presents a clinical case to demonstrate, step by step, the crown-lengthening procedure. Concurrently the clinical rationale for these steps is also explained.

New ideas and advancing technologies in periodontology: surgical options with advancing technologies.

Extensive clinical studies over the last two decades have documented the effectiveness of both non-surgical and surgical periodontal therapy. When deemed necessary, surgery is usually performed as an elective phase of therapy, within a programme of ongoing maintenance care. Traditionally surgical therapy has been aimed at the treatment of the periodontal pocket by resective procedures. However, research has now focused on reconstructive surgery, with the objective of regenerating the structure of the lost periodontium (cementum, periodontal ligament and also alveolar bone). With advancing technology, materials and surgical modalities that have been advocated to facilitate periodontal reconstruction fall into the following main categories: 1. Chemical and biochemical conditioning agents, e.g. citric acid, fibronectin, tetracycline, growth and differentiation factors. 2. Transplants of autogenous or allogeneic (osteogenic or osteoinductive) materials, e.g. osseous coagulum, decalcified freeze-dried bone allograft. 3. Implants of alloplastic (osteoconductive) 'filler' materials, e.g. hydroxyapatite, tricalcium phosphate. 4. Guided tissue regeneration (GTR) utilising membranes, e.g. Teflon (e-PTFE), collagen, polylactic acid. 5. Combined techniques, e.g. GTR and allograft/alloplast. The scientific evaluation and the role of these reconstructive surgical procedures in contemporary dental practice is discussed in this paper.

Subcortical bone grafting for ridge augmentation.

A surgical technique for augmentation of the alveolar ridge, involving horizontal osteotomy in the anterior part of the mandible with insertion of an autogenous bone graft, was studied in monkeys. The technique of closure results in an immediate vestibuloplasty. Results of the study showed a significant improvement in alveolar ridge height with minimal resorptive changes during the experimental period of 50 weeks. The effect of stress on the graft site was not evaluated. However, it is hypothesized that this technique would result in less resorptive changes than in onlay bone grafts because of the subcortical placement of the autogenous bone.

Primary (early) alveolar bone grafting.

Early primary bone grafting is successful when performed as a separate operative procedure after lip repair and before palate closure. It must be done in conjunction with neonatal orthopedics. The graft is placed only after the alveolar segments have molded and grown to a butt joint. Minimal soft-tissue dissection of the alveolus and maxilla are performed. The graft stabilizes arch form, allows for tooth migration and eruption through its site, and decreases anterior and posterior crossbite. There is no facial growth attenuation, and a good foundation for further soft-tissue growth is provided.

Secondary (intermediate) alveolar bone grafting.

Secondary bone grafting of the maxilla and the residual alveolar clefts at the stage of transitional dentition, and in conjunction with orthodontic treatment, has become a well-accepted treatment modality. This article discusses the goals of the procedure, the timing of the bone graft, and the design of the flap for soft-tissue coverage of the bone graft.
