The role of temporomandibular joint surgery in the treatment of patients with internal derangement.

Surgery of the temporomandibular joint (TMJ) has made considerable progress, although significant failures have plagued this field in recent years. Despite the controversies, surgery of the TMJ continues to have a small but important role in the management of specific temporomandibular disorders. This article presents an overview of TMJ surgery. It is concluded that careful case selection is the most important aspect for a successful outcome.

A re-evaluation of the importance of disc position in temporomandibular disorders.

During the 1970s there was a resurgence of interest in disc displacement as being central to the pathology of internal derangement. Since then it has been proposed that a displaced disc can result in pain, mandibular dysfunction, degenerative joint disease and mandibular growth disturbances. Two decades later, and with the introduction of sophisticated investigations and treatment modalities, doubts have emerged as to true pathological significance of disc position. Evidence derived from clinical observations, autopsy material, imaging studies and surgical findings has failed to establish strong support for the central role of disc displacement in internal derangement of the temporomandibular joint.

Temporomandibular joint arthrocentesis and lavage for the treatment of closed lock: a follow-up study.

OBJECTIVES: Temporomandibular joint (TMJ) arthrocentesis and lavage, first described in the North American literature in 1991, is a simplified method used for the treatment of severe, limited mouth opening. The purpose of this study is to evaluate the efficacy of this technique as a treatment for closed lock of the TMJ. DESIGN: Forty-six patients with persistent closed lock of the TMJ of acute onset were treated by TMJ arthrocentesis and lavage with manipulation in an out-patient setting. Clinical data was collected in the form of visual analogue scales for pain and chewing ability, and measurements of maximum mandibular opening before and after treatment. RESULTS: On follow-up ranging from 6 to 30 months, jaw opening and mandibular function had significantly improved (p < 0.001), and pain had substantially decreased in all but one patient as a result of this procedure. CONCLUSION: TMJ arthrocentesis and lavage is recommended as a simple alternative to more invasive TMJ procedures as an effective technique for the treatment of acute persistent closed lock of the TMJ.

Temporomandibular disorders. 2. Non-surgical treatment.

There are many treatment modalities for temporomandibular disorders (TMD), most of which are effective in controlling symptoms, at least in the short term. The non-surgical treatment of temporomandibular disorders continues to be the most effective way of managing over 80 per cent of patients who present with symptoms of temporomandibular pain and dysfunction. In this, the second article in the series, a general overview of the current non-surgical treatment strategies for TMD will be presented.

Morbidity from anterior ilium bone harvest. A comparative study of lateral versus medial surgical approach.

The morbidity of bone harvest was compared between anterior lateral and medial surgical approaches in a randomized prospective study. Forty consecutive patients, each requiring a minimum 40 cc of loose corticocancellous bone for maxillofacial reconstruction, were randomly placed into two equal groups. Morbidity vectors assessed included bone volume, blood loss, length of surgery, length of hospital stay, incidence of seroma, incidence of anterior thigh paresthesia, postoperative pain, and gait disturbance. The results demonstrated no significant difference in morbidity between these two approaches; therefore selection of either approach is the surgeon's personal preference. A thorough understanding of the osseous anatomy of the anterior ilium and its muscular attachments, a good surgical technique, an efficient surgical team, and a continuous flow of required surgical instruments are essential to reduce the morbidity of bone harvest.

Is there a role for temporomandibular joint surgery?

In North America, surgery of the temporomandibular joint (TMJ) has made considerable progress, although significant failures have plagued this field in recent years. In spite of the controversies, surgery of the TMJ continues to have a small, but nonetheless, important role in the management of specific temporomandibular disorders (TMD). A general overview of the current thinking in TMJ surgery is presented with the clear message that careful case selection is the most essential ingredient for a successful outcome.

Prevalence and variance of temporomandibular dysfunction in orthognathic surgery patients.

Seventy-five patients were studied retrospectively to assess the prevalence and variance of temporomandibular dysfunction in an orthognathic surgery population. Preoperatively, 49.3% of the sample presented with temporomandibular dysfunction. After orthognathic surgery, of the symptomatic patients, 89.1% had improved temporomandibular function after surgery, 2.7% were unchanged, and 8.1% had increased symptoms. Of the patients asymptomatic prior to surgery, 7.9% developed temporomandibular dysfunction postoperatively. Temporomandibular dysfunction was significantly more prevalent in patients with a Class II skeletal deformity than in those with a Class III deformity, and temporomandibular function generally improved in both groups postsurgically.

Oral and maxillofacial surgical therapy for the older adult.

Older adults can present with a wide range of oral and maxillofacial diseases and conditions, and many of these are best treated surgically. One of the distinguishing features of geriatric surgery is the large percentage of older adults who have medical conditions that must be planned for perioperatively. Good communication between the surgeon and the primary care physician is important for this perioperative management. Orofacial infections, the most common of which are odontogenic in origin, require some form of surgical treatment and may or may not require treatment with antibiotics. Preprosthetic and reconstructive surgery may be necessary to treat the sequelae of oral and maxillofacial fractures, the sequelae of tooth loss, or surgical defects incurred during the treatment of cancer, osteomyelitis, osteoradionecrosis, or disorders of the TMJ.

An alternative explanation for the genesis of closed-lock symptoms in the internal derangement process.

Clinical and surgical data on 194 operated joints (135 patients) were used to substantiate a new concept challenging the presumed natural history of temporomandibular internal derangement (ID). A number of findings were incompatible with the traditional depiction of a progressive process based on gradual changes in disc position and shape. These findings were a lack or correlation between increasing age and the stages of the process; the percentage of patients in the third stage (closed lock) with limited opening (less than 25 mm) too severe to be caused solely by a nonreducible, displaced disc; the unexpectedly high incidence (greater than 50%) of normally shaped discs in the third stage of the process. A specific condition of severe and stubborn limited maximal mouth opening caused by total cessation of gliding, liable to occur at any age and unrelated to disc shape or position, which responds successfully to simple treatment by lavage and lysis, pressured injection, or arthrocentesis, was discerned. Lack of gliding was attributed to adherence of the disc to the fossa by a reversible effect such as a vacuum and/or decreased volume of synovial fluid of high viscosity. This condition was deemed worthy of an independent identity, dissociated from disc displacement, as a causative factor in the second and third stages of ID, and particularly as an aid to accurate diagnosis and treatment.

Facial erysipelas: report of a case and review of the literature.

The diagnosis of erysipelas is usually made clinically. Features that help distinguish erysipelas are acute onset, erythema, warmth, edema, pain, fever, and isolated regional involvement with clearly demarcated margins. High ASO titers and response to penicillin therapy are reassuring. Simple uncomplicated erysipelas or cellulitis in adults can usually be treated on an outpatient basis. Extensive facial involvement with fever and a toxic appearance warrants hospitalization. Facial cellulitis or erysipelas in children, unless quite limited, requires hospitalization because of the high risk of Hemophilus influenzae infection and sepsis. Hospitalized patients should show visible signs of resolution and be afebrile for at least 24 hours prior to discharge. They should be maintained on oral antibiotic therapy at home for an additional 7 to 10 days.

Arthroscopic lavage and lysis of the temporomandibular joint: a change in perspective.

Arthroscopic surgery was applied to correct various disorders of the temporomandibular joint (TMJ). Lysis and lavage of the upper TMJ compartment proved of value in patients with anterior disc displacement without reduction ("closed lock"), because it increased the range of mouth motion and alleviated pain in the TMJ. Because this beneficial arthroscopic intervention did not encompass repositioning the disc, its surgical relocation when attempting to overcome dysfunction and pain in the TMJ is questioned.

Panoramic radiography for temporomandibular joint arthrography: a description of arthropanoramograms.

TMJ arthrograms done with panoramic radiography, i.e., arthropanoramography, can demonstrate intracapsular disk displacement and perforation pathoses. These views are very practical for inferior synovial cavity arthrograms performed in the dental operatory since panoramic radiographic machines have become common in modern dental practices. Specific advantages of arthropanoramography include the decreased financial cost and decreased radiation exposure to the patient. Arthropanoramography does not replace tomography or videofluoroscopy in TMJ arthrography. It is, however, described as a simple alternative to the more conventional forms of arthrography.
