Outcomes and Survivorship of Biomet Microfixation Total Joint Replacement System: Results From an FDA Postmarket Study.

Purpose: In February 2011, the Food and Drug Administration issued a postmarket surveillance order to all manufacturers of temporomandibular joint (TMJ) implants in the United States. The objective of the present study was to measure implant subsequent surgical intervention (SSI) among patients who had undergone TMJ reconstruction with the Biomet TMJ replacement system (Zimmer Biomet, Warsaw, IN).

Materials And Methods: A prospective observational study was conducted by sending a questionnaire to patients who had received a Biomet TMJ replacement system from 1995 to 2010 in the United States.

Microbiology Alloplastic Total Joint Infections: A 20-Year Retrospective Study.

Purpose: Prosthetic joint infection (PJI) is a rare complication of temporomandibular joint replacement (TJR). This study evaluated TJR PJIs at the authors' institution over a 20-year period, including micro-organisms cultured, antibiotic resistance patterns, and intraoperative protocols of TJR.

Patients And Methods: Patients were identified using Current Procedural Terminology and International Classification of Diseases, Ninth Revision codes and surgical logs from January 1995 through 2015.

Retrospective study of facial nerve function following temporomandibular joint arthroplasty using the endaural approach.

The aim of this retrospective case-control study is to evaluate the incidence of facial nerve injury associated with temporomandibular joint (TMJ) arthroplasty using the endaural approach for the treatment of TMJ pathology. The sample consisted of 36 consecutive patients who underwent TMJ arthroplasty. A total of 39 approaches were performed through an endaural incision.

Pigmented villonodular synovitis of the temporomandibular joint.

Pigmented villonodular synovitis (PVNS) is a proliferative disorder that affects synovium-lined joints, bursae, and tendon sheaths. It appears in both diffuse and localized forms, depending on the extent of synovial involvement. PVNS rarely involves the temporomandibular joint (TMJ); when it does, it manifests clinically as a slowly growing and painless preauricular mass that resembles a parotid tumor.

Biomet Microfixation Temporomandibular Joint Replacement System: a 3-year follow-up study of patients treated during 1995 to 2005.

Purpose: To assess the safety and efficacy of a stock alloplastic total temporomandibular joint (TMJ) implant system, the Biomet Microfixation TMJ Replacement System.

Materials And Methods: During a 10-year multicenter clinical trial from 1995 to 2005, 442 Biomet Microfixation TMJ Replacement Systems were implanted in 288 patients (154 bilaterally and 134 unilaterally). Patients were followed at landmark times, including the date of surgery and at 1 month, 3 months, 1 year, 1 year 6 months, and 3 years.

Posttraumatic temporomandibular joint disorders.

The temporomandibular joint (TMJ) has many essential functions. None of its components are exempt from injury. Facial asymmetry, malocclusion, disturbances in growth, osteoarthritis, and ankylosis can manifest as complications from trauma to the TMJ.

Management of surgical failures.

Surgical intervention is appropriate in a small percentage of patients with temporomandibular joint disorders when it is based on a specific diagnosis of intracapsular pathology not amenable to nonsurgical modalities. Expected advances in our understanding of the complex molecular, biochemical, and genetic factors that influence these disease states clearly will allow less invasive techniques and even obviate the need for some open arthroplastic interventions altogether in the future. In the meantime, reasonable, well-intentioned surgeons must rely on the current body of surgical knowledge to use surgery as judiciously as possible.

Fluid and electrolyte management and blood product usage.

Traditionally, the majority of oral and maxillofacial surgery patients are young and healthy. With the ever-expanding scope of the specialty, however, more surgically extensive procedures increasingly are being performed on more medically complex patients. To optimize comprehensive patient care, oral and maxillofacial surgeons are obligated to possess a firm knowledge of the basic principles of fluid management and use a sound strategy for blood product usage.

Novel oral findings in Schimmelpenning syndrome.

We report a patient with Schimmelpenning syndrome with two previously unreported oral manifestations: multiple pigmented malformed teeth and an adenomatoid odontogenic tumor of the anterior mandible. Also found were multiple complex odontomas, bilateral maxillary fibro-osseous lesions and recurrent central giant cell granulomas of the jaws.

Severe proliferative congenital temporomandibular joint ankylosis: a proposed treatment protocol utilizing distraction osteogenesis.

The classical treatment for temporomandibular joint (TMJ) ankylosis in children: 1) joint release; 2) arthroplasty; 3) reconstruction; and 4) postoperative physical therapy (PT), is often unsuccessful. Postoperative physical therapy is difficult in the young patient due to poor cooperation. Moreover, there is a subgroup of patients who have a refractory congenital proliferative bony process that is the cause of their disease.
