21/155. Craniofacial and dental manifestations of proteus syndrome: a case report.

    The proteus syndrome is a rare congenital hamartomatous condition that is characterized by a wide range of malformations, sometimes involving the face. Common manifestations include partial gigantism, congenital lipomas, and plantar hyperplasia. In this report we describe the craniofacial clinicopathological development in a girl with proteus syndrome from age 6 to 20 years. The patient had pronounced hemifacial hypertrophy, exostoses in the left parietal region, and enlargement of the inferior alveolar nerve and mandibular canal in the affected region. The dental development of the affected left mandible and maxilla was characterized by extremely premature development and eruption of the primary and permanent teeth and by pronounced idiopathic root resorptions. The multidisciplinary management of the patient and the treatment outcome is reported. A review of the Proteus patients in the literature who exhibited manifestation in the craniofacial region is presented. ( info)

22/155. aneurysm of popliteal artery caused by cartilaginous exostosis. A case report.

    A case is reported of traumatic aneurysm in a young man, caused by cartilaginous exostosis distally in the femur. An analysis is given of 18 similar cases from the literature. ( info)

23/155. Exostosis following a free gingival graft.

    BACKGROUND: There have been few cases reported of exostoses following a free gingival graft. In 1980, a free gingival graft was placed on the facial level of 33-34, developing over the years a significant enlargement. In 1999, since the patient felt progressively uncomfortable with the enlarged area, its surgical reduction was proposed. METHOD: Under local anesthesia, the hard tissue developed under the previously-grafted area, was significantly reduced. The specimen, together with a fragment of the covering soft tissue, was sent for histological analysis. RESULTS: The surgical wound healed uneventfully, and the patient was satisfied with the results. The histology showed the presence of mature bone surrounded by a dense connective tissue, whereas the gingival tissue showed acanthosis and fibrosis. CONCLUSION: The development of exostoses following a free gingival graft can be considered an unpredictable, albeit infrequent side-effect of this procedure. The fact that most of these exostoses appear in the cuspid-premolar area, deserves further consideration. ( info)

24/155. subclavian vein thrombosis caused by an unusual congenital clavicular anomaly in an atypical anatomic position.

    The optimal surgical management of subclavian vein effort thrombosis remains a dilemma because outcomes after different treatment strategies are only on the basis of small retrospective series. SVT treatment should be on the basis of the cause of thrombosis. Primary effort thrombosis or Paget-Schroetter syndrome frequently necessitates a surgical approach. The type of surgery has to be individualized after careful diagnostic evaluation. We report a congenital clavicular exostosis that had not been identified with chest radiograph and computed tomographic scan that caused SVT in a young woman. This unusual cause of Paget-Schroetter syndrome was treated with a unique approach. ( info)

25/155. Hard palate mucosal grafts for defects of the nail bed.

    The authors present 2 children in whom a hard palate mucosal graft was used for a defect of the nail bed after resecting subungual exostosis. After the tumor was resected with the overriding nail bed, hard palate mucosa without periosteum was grafted to the nail bed defect. In both patients the graft took completely, and within 2 weeks after the operation the patients were able to enjoy activities of daily life, including athletic movement, without any symptoms. Nail growth was uneventful and was complete in 4 or 5 months after the operation without any complications. The authors think that a hard palate mucosal graft is a valid choice for a defect of the nail bed, and the mucosa does not need to be harvested with periosteum. The grafting of hard palate mucosa without periosteum to a defect of the nail bed contributes to a shorter healing time, resulting in a reduction in the period of restriction of movement in activities of daily life, and this is a great advantage in children.

26/155. Late sequelae of secondary Haglund's deformity after malunion of tongue type calcaneal fracture: report of two cases.

    We are reporting two cases of calcaneal fractures with posterior heel pain due to a prominent superior calcaneal tuberosity impinging on the achilles tendon after a tongue type fracture. Malunion of the tongue fracture fragment resulted in the symptomatic bony prominence, which we defined as the secondary Haglund's deformity. Both cases were treated with resection of the superior calcaneal tuberosity when symptoms continued after non-surgical treatment. Clinical results after operations were both satisfactory with complete pain relief. ( info)

27/155. Pericardial hemorrhage caused by costal exostosis.

    This report describes a 21-year-old man who presented with pericardial hemorrhage due to a puncture wound of the pericardium by an inward-facing exostosis of the left fifth rib. ( info)

28/155. Exostosis following a subepithelial connective tissue graft.

    This case report describes the formation of an unusual unaesthetic gingival enlargement during a five year post operative period subsequent to a subepithelial connective tissue graft placed facial to teeth #4 and #6. Histological assessment of the enlarged tissue indicated that it consisted of viable bone and marrow. The exostosis was reduced with rotary instruments and acceptable soft tissue aesthetics were created using a carbon dioxide laser for gingivoplasty. Possible causes for this unusual enlargement are discussed. ( info)

29/155. Case report: differential pressure impressions for complete dentures.

    A method of producing a differential pressure, secondary impression of a lower arch with a sharp bony ridge is described. The use of this technique allows the clinician to dictate where the load is to be borne by the mucosa. ( info)

30/155. Dislocation of the mandibular condyle into the middle cranial fossa: report of a case with 5 year CT follow-up.

    A 17-year-old patient suffered a dislocation of the right mandibular condyle into the middle cranial fossa following a motorcycle accident. Reduction was delayed because of serious orthopaedic injuries. The condyle was relocated into the glenoid fossa through a combined neurosurgical and preauricular approach. Five years later the patient presented for removal of wisdom teeth and a CT-scan was done to determine the effects of the trauma and management to the condyle. A fibro-osseous ankylosis had occurred in the right temporomandibular joint. The radiological changes confirm that early management appears to improve the prognosis for these injuries. ( info)
