ABSTRACT
Biopsies of 30 autogenous auricular cartilage grafts previously placed in 21 patients with ankylosis and arthropathy of the temporomandibular joint were studied. These joints were reoperated because of persistent pain and limitation of motion. Histologically, all grafts showed viability of the cartilage. Eighteen cartilage grafts placed after Proplast (Vitek, Inc, Houston, TX) or Silastic (Dow Corning, Midland, MI) implants had been removed, all showed foreign-body granuloma with coexistent intact cartilage grafts. This indicated that the autogenous auricular cartilage was resistant to the foreign-body reaction. All cartilage grafts were encased by fibrous tissue. This overgrowth of fibrous tissue may be responsible for the ankylosis. Seven grafts showed cartilaginous proliferation grossly and all showed proliferation histologically. The cartilage proliferation also may contribute to the persistent symptoms and recurrent limitation of joint motion.

In order to assess the degree of similarity of the infraorbital nerve and inferior alveolar nerve, thirty subjects with no history of sensory injury were examined by a battery of neurosensory tests including: light touch, brush stroke direction, two-point discrimination, and thermal disk temperature assessment. In a matched sample experimental design, the sensibility of the inferior alveolar nerve (lower lip) was compared to the inferior orbital nerve (upper lip). The product moment correlations revealed a significant relationship (degree of sameness) between the upper and lower lip. The comparison of the upper and lower lip appear to be acceptable for retrospective tests for detection of neurosensory injury of the inferior alveolar nerve. Of these tests, light touch appears to be the most consistent while remaining sensitive to individual variation. The thermal disk assessment was least sensitive in that no individual variation could be demonstrated. In addition, there appear to be greater variations in men than in women.

Endothelial damage to heart valves, similar to that seen with rheumatic heart disease, occurs in 50% of all patients with systemic lupus erythematosus. Bacterial endocarditis is a consequence in 1% to 4% of these patients. This rate is greater than the incidence of endocarditis after rheumatic heart disease and compares favorably with the incidence of endocarditis in patients with prosthetic heart valves. At present, it is not possible to accurately delineate the subpopulation of patients with SLE that is at risk for this disease; hence, it is recommended that antibiotic prophylaxis (standard regimen suggested by the American Heart Association) be considered for all patients with systemic lupus erythematosus undergoing dental procedures associated with transient bacteremias.

Although involvement of the jaws by Ewing's sarcoma is uncommon, when it occurs the clinical and radiographic presentation may mimic an inflammatory process, specifically pericoronitis. A case that illustrates this dilemma is presented.

Twenty-one patients who underwent bilateral sagittal split osteotomies using rigid fixation were evaluated by neurosensory testing. Neurosensory tests included light touch (LT), brush stroke direction (BSD), two-point discrimination (2-P), and temperature (T). Tests were conducted using the two-alternate forced choice method. The density of neurosensory disturbance was examined as well as the incidence of neurosensory disturbance as it correlated with age of the patient. The incidence of neurosensory disturbance was 45.2% (19/42) to LT, 52.4% (22/42) to BSD, 33.3% (14/42) to 2-P and 7.1% (3/42) to T. The majority of demonstrable neurosensory disturbances were not dense. Increased age was associated with an increased incidence of neurosensory disturbance.

Twenty adult patients with maxillofacial discrepancies most amenable to correction by Le Fort I osteotomy were evaluated for the incidence of postoperative maxillary sinusitis. Before surgery, each patient was evaluated both radiographically, by Waters' projection technique, and subjectively, according to a brief questionnaire pertaining to sinus symptoms. Identical evaluations were carried out at three- and six-month intervals following surgery. The results show no increase in the incidence of maxillary sinusitis following Le Fort I osteotomy.
