Auriculotemporal syndrome following the preauricular approach to temporomandibular joint surgery.

Forty-seven joints in 28 patients were examined 4 months to 10 years after temporomandibular joint (TMJ) surgery via a modified preauricular approach. Many patients had undergone multiple procedures. None of the patients had any subjective or objective evidence of auriculotemporal syndrome (ATS), although patients in previous studies with more extensive incisions have demonstrated ATS. It was concluded that ATS is an unlikely complication following TMJ surgery. A small incision without an oblique superior extension may further reduce the risk.

Temporomandibular joint after meniscoplasty: appearance at MR imaging.

Twenty-five temporomandibular joints (TMJs) were studied in 20 patients who had undergone meniscoplasty. In all patients, preoperative magnetic resonance (MR) images showed anteriorly dislocated disks; all patients underwent a similar postoperative MR examination an average of 6 months after surgery. The results of these studies were correlated with clinical results of surgery, which were classified as poor, fair, good, or excellent at follow-up MR imaging. In 10 TMJs (eight patients [40%]) the clinical results were excellent or good; in 15 TMJs (12 patients [60%]), fair or poor. The position of the disk relative to its preoperative position was a good discriminator in determination of the clinical success of meniscoplasty. After surgery, in all patients with good or excellent results, the disks appeared to be in a normal or an improved position compared with that prior to surgery; in those with poor or fair results, the TMJs had anteriorly dislocated disks that showed no improvement.

Transcranial radiographic and tomographic analysis of the lateral and midpoint inclined planes of the articular eminence.

A radiologic study of the articular eminence was performed on 10 skulls by means of tomograms and transcranial radiographs. Angulation of the articular eminence at the lateral and midpoint inclined planes was measured from the radiographs and compared with direct anatomic measurements. With both radiographic methods, the results showed no significant difference between left and right side measurements. The mean angulation of the midpoint inclined plane was significantly greater than that of the lateral inclined plane with both techniques. With transcranial radiographs, the angulation values were the same as the direct anatomic measurements despite a 25-degree change in skull orientation required for the radiographic method. In the tomographic study, all measurements corresponded with the anatomic and transcranial measurements except that angulation of the lateral inclined plane differed slightly from the direct anatomic measurement. The results show that both tomography and transcranial radiography are adequate for visualization of the midpoint region. However, tomography is preferable for viewing the lateral aspect of the articular eminence.

Intercanthal and interpupillary distance in the black population.

Intercanthal distance is an important measurement in the evaluation of congenital deformities and posttraumatic telecanthus. In this study 100 black patients (71 female and 29 male) were measured for intercanthal and interpupillary distance. For the overall group the mean intercanthal distance was 33.9 +/- 3.0 mm; previous studies of white persons and mixed populations indicate an average of 32 +/- 3 mm. The mean interpupillary distance for this study was 63.7 +/- 3.7 mm; previous studies indicate an average of 63 +/- 3 mm. This study suggests that the intercanthal and interpupillary distances in blacks are similar to findings of previous studies on whites and mixed populations.

Double-blind comparison of meclofenamate sodium plus codeine, meclofenamate sodium, codeine, and placebo for relief of pain following surgical removal of third molars.

A single-dose, randomized, double-blind, parallel-treatment study was performed in 200 outpatients with acute pain caused by the surgical removal of impacted third molars. Meclofenamate 100 mg plus codeine 60 mg, meclofenamate 50 mg plus codeine 30 mg, meclofenamate 100 mg, codeine 60 mg, and placebo treatment groups were compared for sum of pain intensity differences, peak pain intensity difference, sum of pain relief scores, peak pain relief, number of observations at which pain was half relieved, overall evaluation of effectiveness, and time to remedication with a backup analgesic. Meclofenamate 100 mg plus codeine 60 mg was significantly more effective (P less than .005) than codeine 60 mg for all variables except number of observations at which pain was half relieved. Both meclofenamate-codeine combinations and meclofenamate 100 mg alone were significantly more effective (P less than .005) than placebo for all variables. Eleven adverse experiences were reported in 7 patients (3.5%); the most common was somnolence in 1 patient receiving meclofenamate 100 mg plus codeine 60 mg, in 2 treated with meclofenamate 50 mg plus codeine 30 mg, and in 1 treated with codeine 60 mg.

Technological methods in the diagnosis and treatment of temporomandibular disorders.

Although there have been numerous technological devices introduced for the diagnosis and treatment of temporomandibular disorders, many are either ineffective or are research tools without direct clinical application. This article reviews the various modalities and makes recommendations regarding their effectiveness based on the available clinical and scientific evidence.

Delayed healing of muscle after injection of bupivicaine and steroid.

The purpose of this study was to evaluate the histologic changes that occur in an area of rat skeletal muscle injected with a local anesthetic and steroid combination. Thirty adult male laboratory rats were assigned to one of six groups. Group 1 received bupivicaine injected into the right gastrocnemius muscle; Group 2 received procaine; Group 3 received bupivicaine and triamcinolone; Group 4 received procaine and triamcinolone; Group 5 received triamcinolone; and Group 6 received normal saline. Animals were sacrificed at 24 hours and at 1, 2, 3, and 4 weeks. The saline, steroid, and procaine groups showed minimal tissue reaction. The procaine/steroid group had focal areas of inflammation at 24 hours but none on subsequent evaluations. The bupivicaine group showed moderate localized necrosis of muscle fibers and a mild inflammatory cell response at 24 hours. Regeneration of muscle fibers was seen at 1 week, and at 3 weeks the tissue had returned to normal. The bupivicaine/steroid group showed extensive localized necrosis of muscle fibers with a heavy inflammatory cell response at 24 hours. These areas of necrosis persisted throughout the 4-week post-injection period, although some muscle fiber regeneration and fibrosis were also noted. This study shows that bupivicaine produces more tissue reaction than procaine and that the addition of steroid to bupivicaine increases the initial tissue damage and prolongs the healing phase.

Nasotracheal tube obstruction from a central incisor. Report of a case.

After maxillofacial trauma, teeth and other objects can become potential foreign bodies. Whenever possible, careful examination before intubation should be undertaken to avoid serious morbidity secondary to aspiration. The anesthesiologist should be informed and necessary preventive measures taken. This article describes a situation in which this not being done could potentially have led to serious complications.
