1/44. 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.

2/44. 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.

5/44. Three-dimensional computed tomography in evaluation of ankylosis of the temporomandibular joint.

    ankylosis is an uncommon disease of the temporomandibular joint (TMJ), the effective treatment of which requires detailed preoperative evaluation of the type and extent of the deformity. As well as lateral radiographs and computed tomography (CT), three-dimensional CT has been introduced to improve the preoperative evaluation. We present six patients with ankylosis of the TMJ who were evaluated by three-dimensional CT before and after condylectomy. Preoperative findings were compared with operative findings. Three-dimensional CT provides a detailed three-dimensional image of the TMJ non-invasively and we suggest that it is a valuable tool for evaluation of ankylosis in the TMJ.

6/44. A 'made in one piece' skeleton in a 22-year-old man suffering from sickle cell anaemia.

    A 22-year-old African male with known sickle cell anaemia was referred by a Congolese medical centre with a request to improve his poor physical condition. He was unable to walk, stand or sit because his large joints and his spine were either ankylosed or very rigid. Radiographs showed joint fusion from the third to the fifth cervical vertebrae, of both hips, of the left knee, and a bilateral osteonecrosis of the humeral head. There was no scintigraphic evidence for an active osteomyelitis (99mTc-MDP (methyldiphosphonate) bone scan, Tc monoclonal antigranulocyte scan and 99mTc sulphur colloid scan). To improve his mobility the right femoral head was resected in June 1997; 14 days later the left femoral head was resected. Four months after the resection of the right hip, a right uncemented total hip prosthesis was implanted on this side. One month later the same type of hip arthroplasty was performed on the left side. During the postoperative rehabilitation period the patient regained autonomy. We have found no previous reports of such severe and multiple joint complications in a single patient suffering from sickle cell anaemia.

7/44. temporomandibular joint ankylosis: review of the literature and report of two cases of bilateral involvement.

    The factors predisposing to ankylosis and the probable pathogenesis are discussed, as treatment, both past and present. arthroplasty with Silastic interposition is presented as an acceptable means of managing ankylosis, as shown in two case reports. The ultimate postoperative result is dependent on surgical timing, surgical technique, and attention to postsurgical physiotherapy.

8/44. Mandibular distraction in temporomandibular joint ankylosis.

    Condylar damage during childhood can produce ankylosis and alteration of the mandibular growth. In case of unilateral ankylosis occurring in early childhood, a mandibular hypoplasia of the affected side may develop. The patients have limitation of mouth opening, facial asymmetry, and chin deviation toward the affected side. The aims of this study are to show the use of distraction osteogenesis in mandibular hypoplasia associated with ankylosis and to present our experience with a new therapeutic option for the treatment of mandibular hypoplasia with unilateral ankylosis in the childhood consisting of the association of arthroplasty to treat the ankylosis and mandibular distraction to correct the facial asymmetry, both accomplished in the same surgical procedure. From November of 1996 to November of 1997, three male patients aged 2, 7, and 13 years with mandibular hypoplasia and ankylosis were treated by distraction osteogenesis. An arthroplasty consisting of the resection of the ankylotic block and interposition of a temporalis muscle flap, plus coronoidectomy was done in two of them and mandibular distraction was done in all three patients. Articular functional rehabilitation began on the first postoperative day. Mandibular distraction began on the fifth postoperative day with a rate of 1 mm per day, ending when the facial symmetry was achieved. From the first postoperative day, an increase in the mouth opening was achieved; this increase continued until ending the distraction. The average duration of distraction was 22 days. Average duration of consolidation was 6 weeks. Oral opening increased from 10 mm to 35 mm in the 7-year-old patient, from 9 mm to 27 mm in the 2-year-old patient, and from 14 mm to 38 mm in the 13-year-old patient. To date, oral opening and facial symmetry persist. Osseous mandibular distraction together with arthroplasty offers an excellent new alternative for treatment of patients with mandibular hypoplasia and associated ankylosis, with minimal morbidity and complications.

9/44. Preoperative arterial embolization in heterotopic ossification: a case report.

    We report a case of preoperative embolization in a 64-year-old patient suffering from total stiffness of the right hip joint due to heterotopic ossification following brain injury and pertrochanteric fracture of the right femur. A previous attempt of operative treatment could not be performed successfully due to bleeding complications. After the embolization of the correlating hypervascularisation, the surgical procedure was redone and finished with good result and minimal bleeding complications during the operation and a tolerable drop of the haemoglobin concentration postoperatively.

10/44. Preserved costal cartilage homograft application for the treatment of temporomandibular joint ankylosis.

    ankylosis of the temporomandibular joint has been a daunting problem in oral and maxillofacial surgery. Condylectomy with gap arthroplasty is the basic technique for treatment of the fully grown patient. In the past, reconstruction has primarily been accomplished with alloplastic materials or with autogenous tissue harvested from the patient. joints reconstructed with alloplastic materials have been subject to complications such as acute infection and chronic inflammatory problems as a result of foreign-body reaction with the immune system. Biologic reconstruction with autogenous materials does expose the patient to the risk of complications at the donor site. In the last 4 years, we have treated seven patients between the ages of 20 and 42 years who had complete temporomandibular joint ankylosis. In each patient, the affected joint was exposed through an extended preauricular incision. The ankylosed mandibular condyle with the surrounding abnormal bone, together with the coronoid process, was resected and removed. The ankylosed area was resected until an improvement of at least 15 mm in the interincisal opening distance was obtained. A solvent-preserved homologous cartilage graft was sculpted according to the size and shape of the gap and was then placed in it as interpositional material. Physical therapy, including active and passive mouth-opening exercises, began on the second postoperative day and continued for 6 months. patients were observed for 6 months to 4 years. During this period, no major complications were noted, and satisfactory results were obtained. The initial mean interincisal opening distance was 15.2 mm after surgery, and the final mean interincisal opening distance was 32 mm after completion of physiotherapy. No recurrence was seen during the 4 years of follow-up. This technique seems to be an effective, time-saving, and simple alternative to other methods of joint reconstruction in adults who have fairly extensive ankylosis of the temporomandibular joint. In this article, a description of the surgical technique, a review of all cases, and recommendations for the use of this type of graft material are discussed. Our clinical experience over the past 4 years with the use of preserved homologous costal cartilage grafts as interpositional material has been encouraging.
