Ultrasound treatment of cellulitis in the maxillofacial region: a ten-year experience.

AIM: To evaluate the effect of therapeutic ultrasound in the treatment of cellulitis in the maxillofacial region. PATIENTS AND METHODS: We report our experience in the management of maxillofacial cellulitis in thirty six patients using therapeutic ultrasound as an adjunct to the standard treatment. The patients were allocated to two groups: group A, treated by surgery, drugs and ultrasound therapy, and group B, where the patients were treated only surgically and medicamentously. The effect of treatment was evaluated on the basis of inflamed tissue volume reduction and normalization of tissue structure determined by ultrasonography. RESULTS: The dynamic changes in the mean values of inflamed tissue volume indicated more rapid reduction in group A in which therapeutic ultrasound was applied. Analysis of the ultrasonographic images in group A demonstrated merging of the miliary liquid foci as early as the first day of treatment. They coalesced, and this coincided with the initiation of purulent discharge. The reduction in volume was due to the accelerated elimination of breakdown inflammatory products from the tissues. CONCLUSION: The better results in group A compared with group B suggest that the method for ultrasound management was effective and could be recommended for use in clinical practice.

Vertical ramus osteotomy for treatment of mandibular prognathism.

Following a brief literature review of treatment modalities for mandibular prognathism the authors propose a simplified method for vertical ramus osteotomy. The method was successfully used in 24 patients with mandibular prognathism (alone or in combination with open bite). Postoperative complications (suppuration of the operative wound) were found in 2 patients (8%), and postoperative recurrences--in 5 patients (20.8%). No complications, usually associated with sagittal and vertical intraoral osteotomies (hypoesthesia of the trigeminal nerve, Frey's syndrome, dissecting aneurysm of the internal carotid artery) were found to be consequential to the proposed method.

Sarcomas of the mandible. Literature review and case reports.

Sarcomas of the maxillofacial region are rare tumors presenting with wide variety of histopathological and clinical features. The authors treated six patients with sarcomas of the mandible over a period of ten years: 2 patients with fibrosarcomas, 2 with lymphosarcomas, one with osteogenic sarcoma and one with chondrosarcoma. The patients' ages ranged from 28 to 65 years, one was male and five - female. The present study reports three cases (osteogenic sarcoma, fibrosarcoma, chondrosarcoma) with specific clinical and radiographic characteristics, demonstrating the differences between the various types of sarcomas. Special attention is paid to the first clinical signs and symptoms, and to the differential diagnosis with inflammatory conditions (post-extraction alveolitis, chronic odontogenic osteomyelitis), benign tumors (osteoblastoclastoma, ameloblastoma, odontogenic cysts, fibrous dysplasia) and centrally developing jaw carcinomas. Particular emphasis is given to CT imaging and morphological examinations in making an accurate diagnosis and providing adequate treatment. Early diagnosis and precise surgical treatment (total resection or hemiexarticulation, or neck dissection if submandibular or cervical metastases are present) are essential to achieve satisfactory management of these malignant neoplasms. The radiotherapy and chemotherapy administered according to the histologic features of the tumor are also of significance.

A retrospective study of 3326 mandibular fractures in 2252 patients.

Fractures of the lower jaw are the most common facial traumatic injuries and their therapy dominates the treatment activities of oral and maxillofacial surgeons. The present study aimed at determining the types of mandibular fractures and the common trends in their treatment in patients who have sustained facial trauma. The patients have been treated for the last 15 years. MATERIAL AND METHODS. A retrospective study was conducted, which included a series of 3326 mandibular fractures in 2252 patients (1876 male and 376 female, aged 26 months to 85 years) treated in the Clinic of Dentistry between 1986 and 2000. The fracture distribution according to sex and age, anatomic localization, cause, time from trauma to treatment, methods of treatment and complications was investigated. The data were analysed statistically with descriptive statistics, non-parametric (Pearson's chi-square test) and graphic analysis. RESULTS. Mandibular fractures affect all ages; they occur five times as often in males as in females and predominate in young patients (20-29 years of age). The causes for fractures of the lower jaw are varied, the leading factor being assault and alcohol abuse (68.07 +/- 1.19%). According to anatomic localization, the fractures of the angle of the mandible prevail (34.15%), followed by fractures of the body (25.77%) and symphysis (19.57%). Mandibular fractures are treated using different methods, mainly closed reduction and fixation (78.16%) and less frequently open reduction and fixation (20.29%). Complications following treatment of mandibular fractures are encountered in 25.22% of the cases in the form of suppuration of facial wounds, post-traumatic haematomas, development of traumatic osteomyelitis or post-fixation contractures. CONCLUSION. The present study shows that mandibular fractures are not characteristic of certain sex or age, occur in all parts of the jaw and are treated by the methods of both closed and open reduction and fixation. Assault is the major cause of fractures of the mandible.

Sialolithiasis or complex odontoma?

We present a case of a 53-year old woman admitted for treatment in the clinic after detection of radiopacity in the left half of the mandible. The patient was operated on with a tentative diagnosis of complex odontoma. No pathological lesion was found intraoperatively after trepanation of the mandibular bone. Additional clinical examination and contrast media sialography of the left submandibular salivary gland in PA and lateral oblique view were instrumental in making the correct diagnosis and administering the proper treatment. This case demonstrates that difficulties may arise in differentiating between a sialolith and a complex odontoma.

Intermaxillary transalveolar fixation for treatment of mandibular fractures.

The author describes a technique for intermaxillary transalveolar fixation for management of mandibular fractures and discusses the results of treatment of 25 patients (19 male and 6 female) with 39 fractures (12 unilateral, 12 bilateral and 1 triple fracture). The technique was used as the only treatment (22 fractures in 14 patients) or in combination with intraosseous osteosynthesis by wires or miniplates (17 fractures in 11 patients). In comparison to traditional techniques the discussed method is simple and easy to implement, suitable for partially or totally edentulous patients. The indications for using this procedure as an alternative way of treating patients with inadequate dentition or edentulous jaws are presented.

Surgical treatment of chronic mandibular dislocation--report of a case.

Chronic dislocation of the temporomandibular jaw (TMJ) can result from lax joint ligaments and parafunctioning joints; it can also be a consequence of a systemic connective tissue disorder. The authors report a case of hypermobile joint syndrome in combination with mitral valve prolapse. The case was managed by osteosynthesis using modified titanium plate.
