Is Hyaluronic Acid or Corticosteroid Superior to Lactated Ringer Solution in the Short Term for Improving Function and Quality of Life After Arthrocentesis? Part 2.

PURPOSE: Although arthrocentesis has been used for the management of patients with temporomandibular joint pain, the benefit of hyaluronic acid (HA) or corticosteroid (CS) remains uncertain. The purpose of this study was to assess the efficacy of HA, CS, and lactated Ringer solution (LR; placebo) after arthrocentesis for changes in quality of life (QoL), jaw function (Jaw Function Limitation Scale [JFLS] score), and maximum incisal opening (MIO). MATERIALS AND METHODS: This was a prospective multicenter double-blinded randomized clinical trial. Consecutive patients presenting to the oral and maxillofacial departments at Emory University, the University of Pennsylvania, the University of California-Los Angeles, the University of Cincinnati, and the Oregon Health Sciences University were enrolled in the study. Patients were randomized to HA, CS, or LR. All patients underwent arthrocentesis and then instillation of HA, CS, or LR. All patients were evaluated clinically at 1 and 3 months. The outcome variables were QoL, JFLS score, and MIO. Univariate, bivariate, and multivariate statistics were computed, with a P value less than .05 considered significant. RESULTS: One hundred two patients were enrolled in the study. Four were lost to follow-up, leaving 98 patients for analysis of data at 1 month. An additional 51 were lost to follow-up at 3 months, leaving 51 patients for data analysis at this time point. There was no difference among groups for QoL Mental Health Composite score at 1 month (P = .70) or 3 months (P = .69). There was no difference among groups for JFLS score at 1 month (P = .71) or 3 months (P = .98). There was no difference among groups for MIO at 1 month (P = .47) or 3 months (P = .31). All groups showed within-group improvements in JFLS score and MIO at 1 and 3 months. CONCLUSION: Arthrocentesis alone is as efficacious as arthrocentesis with HA or CS in improving jaw function and MIO at 1 and 3 months. QoL is not improved with arthrocentesis alone or in combination with CS or HA.

Is Hyaluronic Acid or Corticosteroid Superior to Lactated Ringer Solution in the Short-Term Reduction of Temporomandibular Joint Pain After Arthrocentesis? Part 1.

PURPOSE: Arthrocentesis has been used for the management of patients with temporomandibular joint (TMJ) pain, with good success. The additional use of hyaluronic acid (HA) or corticosteroid (CS) remains controversial. The purpose of this study was to compare HA, CS, and lactated Ringer solution (LR; placebo) after arthrocentesis. MATERIALS AND METHODS: This was a prospective multicenter double-blinded randomized clinical trial. Consecutive patients presenting to the oral and maxillofacial departments at Emory University, the University of Pennsylvania, the University of California-Los Angeles, the University of Cincinnati, and the Oregon Health Sciences University were enrolled in the study. Patients were randomized to HA, CS, or LR. All patients underwent arthrocentesis and then the instillation of HA, CS, or LR. Patients were evaluated clinically at 1 and 3 months. The primary outcome variable was pain at 1 month (by visual analog scale). Secondary outcome variables were pain at 3 months and analgesic consumption. Univariate, bivariate, and multivariate statistics were computed, with a P value less than .05 considered significant. RESULTS: One hundred two patients were enrolled in the study. Four were lost to follow-up, leaving 98 patients for the final analysis. The mean age of patients in the HA, CS, and LR groups was 39.6, 44.3, and 51.8 years, respectively (P = .02). There was no difference among groups in time to follow-up at 1 month (P = .11). The mean decrease in pain in the CS group was 19% for right-side procedures (P = .12) and 36% for left-side procedures (P = .02). The mean decrease in pain in the HA group was 31% for right-side procedures (P = .01) and 34% for left-side procedures (P = .01). The mean decrease in pain in the LR group was 43% for right-side procedures (P < .01) and 37% for left-side procedures (P < .01). There was no difference in pain decrease among groups (P = .55). There was no difference in the use of narcotic (P = .52) or nonsteroidal anti-inflammatory drugs (P = .71) among groups. CONCLUSION: Arthrocentesis alone is as efficacious as arthrocentesis with HA or CS in decreasing TMJ pain.

Hemophilia: What the Oral and Maxillofacial Surgeon Needs to Know.

Hemophilia will be encountered in the oral and maxillofacial surgeon's office. A thorough understanding of hemophilia is necessary to safely care for these patients. One must understand the severity of the patient's hemophilia as well as whether or not inhibitors are present. The patient's surgical management will be influenced by these two factors. In addition to the possible need to transfuse factors or desmopressin, special care must be taken perioperatively to avoid bleeding complications. This article reviews the overall management of hemophilia A and B as well as the specific perioperative management of these patients.

HIV and AIDS in the adolescent and adult: an update for the oral and maxillofacial surgeon.

HIV and AIDS are among the most complex disease states affecting the worldwide population. OMS and other care providers should have a good understanding of the myriad of systemic effects of this disease and its treatment. This disease affects every system in the body, and in order to provide the best care to these patients, a basic knowledge of this disease process is mandatory. The OMS has the potential to assist in the initial diagnosis of HIV and in recognition of worsening disease. Research continues to examine new treatment modalities, and the search for a vaccine continues. Until a cure is found, the stark statistic seen on bumper stickers remains: 40,000,000 infected. 0 cured.
