Open reduction of condylar fractions of the mandible in conjunction with repair of discal injury: a preliminary report.

Fractures of the condylar process of the mandible may require open reduction and internal fixation in some instances. In previous reports on the management of such cases, no discussion has focused on the associated soft tissue injuries of the temporomandibular joint. In this article, the authors review their experiences with open reduction of condylar fractures in conjunction with soft tissue reconstruction of the disc and associated structures.

Fragmented care of facial fractures.

The treatment of facial trauma currently falls within the purview of several surgical subspecialties, including plastic surgery, oral and maxillofacial surgery, otolaryngology, ophthalmology, and neurosurgery. The complexity of facial anatomy and the newer techniques for skeletal and soft-tissue reconstruction demand interdisciplinary, rather than multidisciplinary, care for these injuries. Interdisciplinary cooperation benefits the patient with a complex facial fracture by: minimizing chances for inadequate primary therapy, promoting discussion of controversial therapy, and providing the optimal therapy. Examples are given of unfavorable results following treatment of facial fractures. Recommendations are made to foster communication between the concerned surgical subspecialties.

Central giant cell lesions of the jaws: a clinicopathologic study.

The biologic behavior of central giant cell lesions of the jaws ranges from quiescent to aggressive with destructive expansion. To date, these variations have not been explained by the findings of routine histologic examination. This retrospective clinicopathologic study of giant cell lesions was performed to search for histologic correlates of biologic behavior. Lesions in 17 patients were classified clinically as nonaggressive (group I) or aggressive (group II). In general, group II lesions affected children at an earlier age, were larger at the time of diagnosis, and recurred more frequently. The following histologic parameters were assessed: fractional surface area occupied by giant cells (FSA), relative size index of giant cells (RSI), stromal characteristics, mitotic index, inflammatory cells, and hemosiderin content. Histologic differences between the two groups were not as clear as the differences in biologic behavior. However, aggressive lesions had a higher RSI, and recurrent giant cells lesions had a higher RSI and FSA; these parameters warrant further study. In addition, electron microscopic differences in a small number of aggressive and nonaggressive lesions were documented.

Fractures of the zygomatic complex.

In 1973 methods for diagnosing and treating zygomatic complex fractures were reviewed, with emphasis on the lateral eyebrow incision for access to the zygomaticofrontal region. The following clinical update reviews alternative approaches to the zygomatic complex (coronal incision, upper eyelid incision), and current concepts of treatment for acute injuries and late deformities secondary to malunion.

Diagnosis and treatment of jaw tumors in children.

A retrospective review of experience with jaw tumors in 48 children over a ten-year period was made. These were predominantly benign, nonodontogenic, mesenchymal tumors. Clinical behavior was variable and often did not correspond to the histologic patterns. The clinically aggressive variants displayed rapid growth usually with associated pain. Resection rather than curettage is appropriate therapy when there has been earlier treatment failure by local tumor removal or rapid tumor expansion, or when tumor extensively invades the jaw. When resection is carried out, facial growth is not adversely affected if early reconstruction with autogenous bone is performed.

Intraoral open reduction of mandibular fractures.

Experience with 31 mandibular fractures treated by intraoral open reduction techniques is reviewed and the techniques described. A 12.9% complication rate was experienced, no complication causing significant morbidity. Indications for intraoral open reduction are reviewed and the literature is discussed. The intraoral open reduction technique is a satisfactory treatment method for selected cases of fractures of the mandible.

Contralateral facial palsy following coronoidectomy. Report of a case.

Contralateral facial palsy has been described as an unusual complication following coronoidectomy. The differential diagnosis of facial palsy is reviewed. An idiopathic Bell's palsy, coincident with the surgical procedure, is the most likely diagnosis in the absence of dislocation or acute fracture involving the ipsilateral condyle.

Intraparotid hemangioma in an adult. Case report and review of the literature.

We have reported a case of a vascular malformation within the parotid gland of an adult. The first symptom was acute onset of pain and swelling, consistent, in retrospect, with a thrombophlebitis and associated vascular congestion. Although the hemangioma of the parotid is not uncommon in young children, it is rare in the adult. Several clues to the diagnosis have been reviewed, all absent in the case reported. The potential confusion with primary salivary pathology is emphasized by this report.

Dentigerous cyst involving maxillary sinus: report of case.

The dentigerous cyst is generally discovered during routine radiographic examination although it may be found because of secondary infection. Although the patient described in this report had symptoms of infection, discovery of the lesion was late in the course of development of the cyst as it grew to a large size within the antral cavity without causing external expansion. The panoramic radiograph is an excellent method to screen for central jaw disease but may not allow adequate assessment of processes involving the maxillary sinuses. As illustrated by this report, when the absence of a third molar is not explained by the patient's history or by the panoramic radiograph, additional radiographs are essential to specifically visualize the sinuses and upper middle part of the face for accurate diagnosis.

Oral mucosal presentation of lymphoma: report of case.

We have presented a case of diffuse mixed lymphocytic and histiocytic lymphoma that appeared as persistent oral ulcerations in a pituitary dwarf with combined variable immunodeficiency. The difficulty in diagnosis is emphasized and the differential features of polymorphic reticulosis, Wegener's granulomatosis, malignant lymphoma, and idiopathic midline destructive disease have been reviewed. Awareness of these disease processes and their distinguishing features may expedite accurate diagnosis.

Case 47, part II: Oral hyperpigmentation associated with Addison's disease.

This case is interesting in several respects. Although diffuse oral hyperpigmentation is suggestive of Addison's disease and should prompt the latter to be a prominent potential diagnosis in any setting, diagnosis was delayed by lack of constitutional and systemic symptoms, normal preliminary hematologic and electrolytic laboratory data, and the strong opinion of the pathologist that the oral mucosal biopsy specimen represented a fixed drug eruption. A subsequent orthopedic complaint and the resultant cooperative efforts of staff persons from several disciplines led to the proper diagnosis.
