Mandibular condyle fracture and dislocation into the middle cranial fossa.

A case report is presented concerning a patient who sustained a condyle fracture with superior dislocation into the middle cranial fossa. Although relatively rare, other cases of central condylar dislocation have been presented and will be discussed and compared. Diagnosis has been a problem, and treatments have varied greatly for these cases. This is the first case on record, however, in which such a dislocation occurred in conjunction with a fracture of the condylar head. In the present case, the dura was covered with temporalis muscle and the glenoid fossa was covered using the fragments of the fractured condyle as an autogenous free bone graft.

[The retromandibular approach in fractures of the mandibular condyle].

Various approaches have been proposed for surgical treatment of displaced condylar fractures included submandibular approach, preauricular approach, rhytidectomy approach or intraoral approach. Since 1992, we used a short retromandibular approach to treat displaced subcondylar fractures with a miniplate. When open reduction and osteosynthesis are required, the retro-mandibular approach is an easy and safe technique for displaced condylar fractures. The aim of this article was to describe the short retro-mandibular approach. Indications for surgical treatment, surgical approach and techniques of osteosynthesis for condylar fractures are discussed.

[Displacement of the titanium endoprosthesis of the mandibular condyle process towards the middle cranial fossa and method for its repair].

A clinical case is presented: endoprosthesis of the articular depression of the temporomandibular joint (TMJ) was used in the treatment of a patient with a complication which developed several years after insertion of an isolated endoprosthesis of the mandibular condylar process. This case is presented as a proof of the efficiency of a complete TMJ endoprosthesis.

Fractures of the mandibular condyle: a review of 466 cases. Literature review, reflections on treatment and proposals.

INTRODUCTION: The incidence of condylar fractures is high. Condylar fractures can be extracapsular (condylar neck or subcondylar) or intracapsular, undisplaced, deviated, displaced or dislocated. Treatment depends on the age of the patient, the co-existence of other mandibular or maxillary fractures, whether the condylar fracture is unilateral or bilateral, the level and displacement of the fracture, the state of dentition and the dental occlusion, and the surgeon's experience. PURPOSE: This report presents the experience acquired in the treatment of 466 condylar fractures over 7 years, reviews the pertinent literature and proposes guidelines for treatment. MATERIAL AND METHODS: The archives of KAT, General District Hospital between 1995 and 2002 were scrutinized and the condylar fractures were recorded. The aetiology, age, sex, level of fracture, degree of displacement, associated facial fractures, malocclusion, and type of treatment were noted. RESULTS: Four hundred and sixty-six condylar fractures were admitted, the male:female ratio was 3.5:1. Road traffic accidents were the main cause and most fractures were unilateral, displaced, subcondylar, occurred on the left side and were treated conservatively. CONCLUSIONS: Early mobilization is the key in treating condylar fractures. Whilst rigid internal fixation provides stabilization and allows early mobilization, conservative treatment is the treatment of choice for the majority of fractures. Children and intracapsular fractures are treated conservatively with or without maxillo-mandibular fixation. Open reduction is recommended in selected cases to restore the occlusion, in severely displaced and dislocated fractures, in cases of loss of ramus height, and in edentulous patients. It may be considered in those with 'medical problems' where intermaxillary fixation is not recommended.

[The use of kinesiography and electromyography in assessing the outcome of a fracture of the mandibular condyles].

The purpose of this work is to consider the sensibility, reliability, and utility of the computerized electromyography and kinesiography in the diagnosis and study of the functional results in patients affected of single or bilateral previous fractures of the condyles. The Authors analyse three clinical parameters and compare them with thirteen parameters gathered from the computerized data and the kinesiogram and electromyogram analysis of a selected sample of thirteen patients with previous fractures of the condyles. This comparison has shown the greatest reliability and sensibility (a larger quantity of instrumental data as regards the clinical checkup and absence of false negative diagnosis) of these techniques with regard to ordinary clinical checkup. Furthermore the features of objectivity, non invasion and easy repetition, indicate that computerized electromyography and kinesiography play an important role in the diagnosis and study of the functional results of fractures of the condyles and in the follow-up examination.

Enlargement of the rabbit mandibular condyle after experimental induction of anterior disc displacement: a histomorphometric study.

PURPOSE: Clinical and autopsy studies have shown that patients with temporomandibular joint dysfunction are more likely to have enlargement and deformity of the condyle and subsequently occlusal disharmony. However, it is not known what causes this enlargement. This study was designed to test the hypothesis that surgical induction of anterior disc displacement (ADD) in the rabbit craniomandibular joint (CMJ) could lead to enlargement and deformity of the condyle. MATERIALS AND METHODS: The right CMJ was exposed surgically, and the discal attachments were severed except for the posterior discal attachment (bilaminar zone). Then, the disc was repositioned anteriorly and sutured to the zygomatic arch. The left joint served as a sham-operated control. CMJ tissues then were removed after fixation at 24 hours (5 rabbits), 1 week (10 rabbits), 2 weeks (10 rabbits), or 6 weeks (10 rabbits), processed, and stained with hematoxylineosin. Histomorphometric assessment was used to evaluate changes in condylar volume, and thickness of the fibrous, reserve cell, and condylar cartilage layers. RESULTS: The results showed a progressive enlargement of the condylar volume in all experimental joints compared with controls (P < .01). The enlargement was attributable to a significant increase in the cartilage thickness and surface area of the nonarticulating portion of the condyle in the 1-week group (P < .01). In the 2- and 6-week groups, there were significant, progressive increases in cartilage thickness and surface area of the articulating portion of the condyle (P < .01). In all animals, increased cartilage thickness was associated with a decrease in the thickness of the fibrous and the reserve cell layers (P < .01). CONCLUSION: It is concluded that surgical induction of ADD in the rabbit CMJ causes enlargement of the condyle, which is in part caused by hyperplasia of the condylar cartilage.
