1/139. Inverted, T-shaped silicone implant for the treatment of temporomandibular joint ankylosis.Reconstruction of the ankylosed temporomandibular joint is a challenging task. speech impairment, difficulties with mastication, poor oral hygiene, facial asymmetry, and mandibular micrognathia results in physical and psychologic disabilities. Various surgical techniques with varying success rates have been reported. Many autogenous and alloplastic materials have been proposed. The authors used an inverted, T-shaped silicone implant for the reconstruction of the temporomandibular joint after the release of the ankylosis in 10 patients without any complications in the postoperative period. The authors assert that the reconstruction of the ankylosed temporomandibular joint with an inverted, T-shaped silicone implant is a reliable and effective alternative. This technique can be used according to the special requirements of each patient and obviating the need for the fixation of the implant and is a safer and better way of using silicone for the treatment of temporomandibular joint ankylosis.- - - - - - - - - - ranking = 1keywords = joint (Clic here for more details about this article) |
2/139. Panclavicular ankylosis in pustulotic arthroosteitis. A case report.A 54-year-old man who had palmoplantar pustulosis showed bilateral, complete osseous fusion of the sternoclavicular and acromioclavicular joints. No significant abnormality was seen in the glenohumeral joint. The left clavicle had a nonunion develop, whereas the right did not. The elevation of the right shoulder was limited to 100 degrees in active and passive measurements. The total external rotation and internal rotation at the side was 135 degrees. This decreased to 90 degrees at 60 degrees elevation and to 10 degrees at maximum (100 degrees) elevation. Based on the kinematic data on normal shoulders, it was thought that the ankylosis of both ends of the clavicle held the scapula unrotated during the arm movement so that, at the arm to trunk angle of 100 degrees, the position of the humerus relative to the scapula was equivalent to that of a normal shoulder in complete elevation. The current case provided an extremely rare clinical setting where shoulder mobility depended only on glenohumeral motion as a result of the complete loss of scapulothoracic motion.- - - - - - - - - - ranking = 0.25keywords = joint (Clic here for more details about this article) |
3/139. Functional rehabilitation of ankylosed temporomandibular joints.Successful chrome-cobalt prostheses have been used to replace the condyle and glenoid fossa in six young macaca irus monkeys. In one group of two animals the left temporomandibular joint was replaced; in the second group the right joint and in the third group both temporomandibular joints were replaced. Neither masticatory function nor ability to open or close the mouth was affected, and all the animals remained in excellent health, living in the colony for 9 to 10 months. A similar surgical procedure was carried out for treatment of three human patients with ankylosed temporomandibular joints.- - - - - - - - - - ranking = 1keywords = joint (Clic here for more details about this article) |
4/139. Using three-dimensional-computerized tomography as a diagnostic tool for temporo-mandibular joint ankylosis: a case report.Roentgenographic examination has long been a useful diagnostic tool for temporo-mandibular joint (TMJ) disease. The methods include TMJ tomography, panoramic radiography and computerized tomography (CT) scan with or without injection of contrast media. Recently, three-dimensional CT (3D-CT), reconstructed from the two-dimensional image of a CT scan to simulate the soft tissue or bony structure of the real target, was proposed. In this report, a case of TMJ ankylosis due to traumatic injury is presented. 3D-CT was employed as one of the presurgical roentgenographic diagnostic tools. The conventional radiographic examination including panoramic radiography and tomography showed lesions in both sides of the mandible. CT scanning further suggested that the right-sided lesion was more severe than that on the left. With 3D-CT image reconstruction the size and extent of the lesions were clearly observable. The decision was made to proceed with an initial surgical approach on the right side. With condylectomy and condylar replacement using an autogenous costochondral graft on the right side, the range of mouth opening improved significantly. In this case report, 3D-CT demonstrates its advantages as a tool for the correct and precise diagnosis of TMJ ankylosis.- - - - - - - - - - ranking = 0.625keywords = joint (Clic here for more details about this article) |
5/139. temporomandibular joint ankylosis: review of thirty-two cases.I have reviewed aetiology, sex, age at time of treatment, clinical features, radiographic findings, anaesthetic techniques, surgical treatment, complications, and results in 32 patients with ankylosis of the temporomandibular joint. Trauma and infection were the commonest causes of ankylosis: 50% and 41%, (n = 13), respectively. The 21-30 year age group had the most trauma cases. Twenty (63%) of the patients presented with bilateral ankylosis. Failing to do jaw-opening exercises was the main cause of relapse.- - - - - - - - - - ranking = 0.625keywords = joint (Clic here for more details about this article) |
6/139. Coronal approach for the replacement of the condylar head in bilateral temporomandibular joint ankylosis: report of three cases.Limitation of mouth opening has long been the chief complaint for patients who suffer from temporomandibular joint (TMJ) ankylosis. For surgical treatment of this disease, several ways have been employed for access to the condylar fossa, including the preauricular, postauricular, perimeatal, endaural and Risdon approaches. In this article, we report three patients with bilateral TMJ ankylosis who underwent replacement of both condylar heads using the bicoronal approach. The advantages demonstrated with this surgical technique are ease of access to the condylar head, ideal surgical exposure field, utility of temporalis muscle and fascia and minimal risk of facial paralysis.- - - - - - - - - - ranking = 0.625keywords = joint (Clic here for more details about this article) |
7/139. ankylosis of the temporomandibular joint as a complication of forceps delivery: report of a case.A two and half years old girl presented with severe limitation of mouth opening, facial asymmetry, inability to masticate, and proclination of the anterior maxillary and mandibular teeth. There was no history of facial trauma, infection or neonatal fevers. A diagnosis of bony ankylosis of the TMJ was made following a confirmation of delivery by means of obstetrics forceps during a difficult labour. The causes of TMJ ankylosis and the sequaele are highlighted.- - - - - - - - - - ranking = 0.5keywords = joint (Clic here for more details about this article) |
8/139. malleus ankylosis: a clinical, audiometric, histologic, and surgical study of 123 cases.OBJECTIVE: malleus ankylosis is a cause of conductive hearing loss that can be difficult to assess, particularly in association with otosclerotic stapes fixation. The aim of this study is to seek the clinical and audiometrical features unique to this pathology. STUDY DESIGN: The study design was a review of malleus ankylosis cases and an analysis of functional results after ossiculoplasty. SETTING: The study was performed at Jean Causse Clinic in france. patients: The authors reviewed a series of 123 ears in 112 patients who underwent surgery for incudo-mallear ankylosis from January 1991 to September 1997. Intervention: The surgical technique depends on the type of pathology encountered. In case of associated stapedial fixation, a stapedotomy with vein graft interposition and reconstruction with a total prosthesis will be performed during a same step. MAIN OUTCOME MEASURES: Clinical evaluation, preoperative and postoperative audiometrical evaluation, operative findings, histologic examination, and postoperative functional results. RESULTS: In our series, a postoperative air-bone gap smaller than 10 dB was obtained in 77% of cases. These results confirm the possibility of managing both pathologies in a single surgical step. CONCLUSION: Incudo-mallear ankylosis remains an unusual pathology but should be systematically assessed during surgery and preferably after separation of the incudo-stapedial joint. A preoperative diagnosis is difficult to ascertain; some audiometrical features allow a suspicion. In this series, it is shown that otosclerosis can be responsible for ankylosis as seems to be confirmed by the two cases presented in this study.- - - - - - - - - - ranking = 0.125keywords = joint (Clic here for more details about this article) |
9/139. Principles of treatment for temporomandibular joint ankylosis.An understanding of the growth and development of the temporomandibular joint (TMJ) is necessary for successful treatment of TMJ ankylosis. The concept of a growth center in the condyle is probably misleading; instead, the soft tissues of the orofacial region seem to provide the primary growth forces. As a result of this concept, methods of treatment should be reexamined.- - - - - - - - - - ranking = 0.625keywords = joint (Clic here for more details about this article) |
10/139. temporomandibular joint ankylosis secondary to Marie-Strumpell disease.Marie-Strumpell disease, or ankylosing spondylitis, is a severe arthritic disorder that may involve the TMJs. Bony alkylosis may result and cause lack of jaw mobility. Familiarity with this disease entity and other arthritic disorders is a necessity for the dentist and oral surgeons.- - - - - - - - - - ranking = 0.5keywords = joint (Clic here for more details about this article) |
