  • Osseous Abnormalities Related to the Temporomandibular Joint
    Seminars in Ultrasound Ct and Mri, 2007
    Co-Authors: Tsukasa Sano, Mika Otonari-yamamoto, Takamichi Otonari, Aya Yajima
    Abstract:

    With the arrival of arthrography, computed tomography, and magnetic resonance imaging, diagnostic imaging of the Temporomandibular Joint has improved tremendously over the last 20 years. In patients with Temporomandibular Joint pain and dysfunction, the main focus was on meniscal pathology. The purpose of this article is to discuss several osseous abnormalities and demonstrate their association with Temporomandibular Joint pain and dysfunction.

  • Common abnormalities in Temporomandibular Joint imaging.
    Current Problems in Diagnostic Radiology, 2003
    Co-Authors: Tsukasa Sano, Mika Yamamoto, Tomohiro Okano, Takehiko Gokan, Per-lennart Westesson
    Abstract:

    Abstract Magnetic resonance imaging has evolved as a prime diagnostic method for soft-tissue abnormalities of the Temporomandibular Joint. The most common Temporomandibular Joint abnormalities are internal derangement and osteoarthritis, but there are many other reasons for pain and dysfunction that are often overlooked. The purpose of this paper is to illustrate several of these more unusual and less well-recognized causes for Temporomandibular Joint pain and dysfunction. For example, internal derangement is often seen in asymptomatic individuals. Another purpose is to illustrate the difference in magnetic resonance imaging of asymptomatic and symptomatic internal derangement.

  • A preliminary investigation of a method of detecting Temporomandibular Joint sounds.
    Journal of Orofacial Pain, 1994
    Co-Authors: Hiroshi Yoshida, Tsukasa Sano, Ryuta Kataoka, Koji Takahashi, Ken-ichi Michi
    Abstract:

    This study established a method of detecting Temporomandibular Joint sounds based on signal-to-noise ratios. After comparing the Temporomandibular Joint signals obtained from three different sites over the skin, the articular eminence was found to be the best site for detecting Temporomandibular Joint sounds; this site provided the highest mean amplitude in the time domain waveform. However, using an electret condenser microphone at the intra-auditory meatus provided a broader, 20-decibel signal-to-noise bandwidth, which resulted in minimized artifacts. This method may be useful for recording Temporomandibular Joint sounds in the differential diagnosis of various Temporomandibular Joint conditions using spectral analysis.

  • Observer performance in describing Temporomandibular Joint sounds.
    Cranio-the Journal of Craniomandibular Practice, 2016
    Co-Authors: Lars Eriksson, Per-lennart Westesson, Hasse Sjöberg
    Abstract:

    AbstractTwenty-two dentists and dental students listened to tape recordings of Temporomandibular Joint sounds from 28 Temporomandibular Joint patients and classified their observations as no sound, clicking, or crepitation. The interobserver agreement was low since the observers classified only 14% of the patients the same. The intraobserver agreement was higher with a mean of 79%. The divergent opinions about the character of Temporomandibular Joint sounds indicate that these clinical signs are not as objective as previously postulated.

  • Custom-Made Total Temporomandibular Joint Prostheses
    Atlas of the oral and maxillofacial surgery clinics of North America, 2005
    Co-Authors: David A. Keith
    Abstract:

    In the multiply operated patient and patients with severe anatomic problems that involve the Temporomandibular Joint, total Temporomandibular Joint reconstruction with a prosthesis may be necessary. The various systems available currently are discussed in a previous issue of the Oral and Maxillofacial Surgery Clinics of North America. This article discusses the general principles involved in total Temporomandibular Joint replacement. The choice of which system to use is left to the preference of the individual oral and maxillofacial surgeon.

  • Complications of Temporomandibular Joint surgery.
    Oral and Maxillofacial Surgery Clinics of North America, 2003
    Co-Authors: David A. Keith
    Abstract:

    The complications of Temporomandibular Joint surgery were reviewed in The Oral and Maxillofacial Surgery Clinics of North America in 1990 [1]. Several reviews of complications and unfavorable outcomes also have been published [2–4] in the last decade. The purpose of this article is to review new contributions to the literature in light of the changing nature of Temporomandibular Joint surgery. In the late 1970s and early 1980s, in response to the ability to image the internal structures of the Joint, there was a trend to address internal derangements, perforations, and other anatomic deviations using open Joint surgery. With this trend came the use of alloplastic materials and the subsequent realization of the damage that these materials could produce. Because of the severity of the destructive lesions caused by giant cell foreign body reactions and other postoperative sequelae, there was a move away from open Joint procedures to less invasive procedures, such as arthroscopy and arthrocentesis. Open Joint surgery remains a necessary part of the armamentarium. A group of patients who have continuing problems as a result of multiple surgical interventions still remains. This article reviews complications of open Joint and arthroscopic surgery, with an emphasis on new information that has become available over the last decade and reviews the current knowledge of the multiply operated patient. The available outcome data for all types of Temporomandibular Joint surgery are discussed. Complications of open Temporomandibular Joint surgery Complications of open Temporomandibular Joint surgery previously reviewed [1–4] include fifth and seventh nerve injury, vascular injury, infection, otologic complications, parotid gland injury, cranial fossa perforation, implant failure, malocclusion, degenerative arthritis, adhesions, and ankylosis. These complications are not addressed in this article.

  • Imaging of the Temporomandibular Joint.
    Current opinion in dentistry, 1991
    Co-Authors: Richard W. Katzberg
    Abstract:

    : Imaging of the Temporomandibular Joint recently has been characterized by a shift in emphasis from plain films, arthrography, and computed tomography toward magnetic resonance imaging. The past year represents the continuation of the era of refinement in magnetic resonance technology not immediately obvious as an advantage for Temporomandibular Joint imaging but nonetheless, of potential significant impact. A few examples of relatively "quiet" developments include: 1) new alloys for lighter weight permanent magnets with reduced operating costs; 2) gradient coil technology for more rapid image acquisition leading to the possibility of true cine magnetic resonance; and 3) smaller, more powerful computers for more rapid data processing. The implications are for comprehensive anatomic and physiologic assessments of the Joint along with increased patient throughput and reduced costs. This review surveys the recent literature on the techniques and selection of imaging modalities, new observations regarding the pathophysiology of Temporomandibular Joint diseases afforded by advances in imaging technology, and my opinions regarding future directions in imaging technology based on my own experience and a review of the current literature.
