Otodental syndrome. A case report.

A 12-year-old boy with characteristic findings of otodental syndrome is presented. Abnormalities of deciduous and permanent dentition included bulbous canines, globe-shaped posterior teeth and agenesis of maxillary premolars. High-frequency sensorineural hearing loss was demonstrated, and results of genetic studies indicated an autosomal dominant trait. This patient presented previously unreported findings, including generalized macrodontia, delayed mineralization of the mandibular premolars, and supplementary permanent maxillary canines.

[CO2 laser sterilization in periradicular surgery: a clinical follow-up study].

Periradicular surgery combined with final laser sterilisation was performed on 62 teeth of 50 patients by 3 trained oral surgeons, according to a well defined treatment protocol. It concerned a 5 Watt continuous wave CO2-laser. After a follow-up period ranging from 6 to 17 months all patients were recalled. 28 patients (56%) or 33 teeth (53%) could be evaluated. The successrate was determined by a questionnaire, a standard clinical examination and an X-ray evaluation. Complete surgical healing was found in 59% of the teeth and incomplete healing in 23%. Uncertain healing and unsatisfactory healing were observed in respectively 11% and 7% of the teeth. Better healing results were found in elements with one endodontic canal (67% complete healing) and when endododontic treatment was combined with the intervention (71% complete healing). Comparison of the results of the present study with comparable studies without laser sterilisation, showed however no statistical significant improvement.

Clinical examination of the T.M.J. interobserver reliability.

A clinical study was performed on 18 healthy persons, chosen at random and without major T.M.J. complaints, by 4 different examiners (2 physiotherapists and 2 oral and maxillo-facial surgeons). The main goal was to examine the interobserver reliability of the different clinical examination methods commonly used in the department of Oral and Maxillo-Facial surgery and physiotherapy. The clinical examination consisted of bilateral palpation of the active movements of the T.M.J., evaluation of the passive movements and evaluation by specific manual distraction and compression tests. Statistical processing was performed with a Pearson correlation coefficient. The critical positive value for a good correlation was never reached. Although evaluation of 5 subjects with minor complaints, shows a low tendency of positive correlation. Therefore, interobserver reliability for the examination of the T.M.J. seems to be fictive in an at random sample. Examination of pathologic cases may be more concordant.

Periostitis ossificans.

Mandibular periostitis ossificans was assessed in a 18-year-old black boy. This form of chronic osteomyelitis (Garré osteomyelitis) resulted from a periostitis on the 4.8 in association with an infected and ankylosed 4.7. Clinically a firm swelling of the right mandibular angle was noticeable. The diagnosis was confirmed by computed tomography and biopsy. After extraction of the causative teeth, in combination with an antibiotic treatment, a good evolution was obtained. The possible pathogenesis and the differential diagnosis are discussed.

[Post-therapeutic follow-up of oral spinocellular epithelioma].

During the follow-up of patients treated for squamous cell carcinoma, dentists have to look for recurrences and metastases. They play also a very important role in the prevention and treatment of the different treatment induced oral sequelae. Special attention is drawn to the postradiation complications like mucositis, xerostomia, radiation caries, trismus and osteoradionecrosis. Despite the fact that no universal accepted protocols are available, the author presents some therapeutic procedures, based on the review of the literature and clinical experience. The importance of a long time follow-up is underlined.

[Atypical histiocytic granuloma].

This report deals with a case of atypical histiocytic granuloma in a male patient of 65 years old. The white ulcerative lesion was located in the upper labial mucosa. No bleeding or pain was observed on palpation. A complete spontaneous healing was observed within two weeks. On histologic examination an excess of atypical cells with multiple mitotic configurations was seen. These cells were histiocytes (this was substantiated by the use of a specific histochemical colour method (KP1-CD 68)). The authors emphasize the difficult clinical differential diagnosis with a traumatic eosinophilic granuloma. Also the other ulcerative lesions, including spinocellular epithelioma, of the oral mucosa must be considered. Only biopsy will differentiate between these entities.

Nodular fasciitis in a temporomandibular joint.

A patient is presented with nodular fasciitis of the right temporomandibular joint. The clinical presentation and radiologic and light microscopic findings are described. Clinicians should be aware of this condition, particularly when there is a history of trauma.

[The Wurzburg titanium miniplate system: evaluation of 3-year utilization].

In this article the use of Titanium miniplates in the maxillo-facial surgery is being examined. After a literature-study concerning the qualities of Titanium and the advantages, disadvantages aswell as indications of the miniplates, the stability of osteotomies using this system is being traced, aswell as its eventual developments. From this research it becomes clear that the miniplates indeed contribute to greater stability of the skeletal fixation in maxillo-facial surgery.

[Orthognathic surgery: a team effort].

Patients in daily practice can be asking us about the problems they experience with their occlusal relationship, facial esthetics and joint dysfunction. If this dysfunction is present in a harmonious facial balance, the treatment plan should be classically dental (building-up plate to free the joint, occlusal equilibration, amalgam reconstructions, crown and bridgework, orthodontics). If the dentist observe a facial imbalance, whether it is antero-posterior, vertical or transversal, the treatment should be in cooperation with an orthognathic team (orthodontist and maxillo-facial surgeon). If the clinical problem is exclusively esthetic, without any relation with dental malocclusion and/or joint dysfunction, the treatment planning can be plastic surgery only.

Management of large oral tumours by mandibular swing and myocutaneous flap.

Median mandibulotomy with mandibular swing combined with immediate reconstruction by a myocutaneous flap has been carried out in 11 patients with large intraoral tumours. Mandibular swing appeared to achieve better local control and caused less problems in resection of these T3 and T4 tumours compared to lateral mandibulotomy. The use of a myocutaneous pectoral flap instead of a deltopectoral skin flap reduced the need for reintervention and abolished that for delayed reconstruction. The combined approach also reduced the time of hospitalization.
