Method to verify the accuracy of model surgery and prediction tracing.

Accuracy of cephalometric tracings and model surgeries is of utmost importance in planning for orthognathic surgery. The technique described allows surgeons to verify position of the models by superimposing a cephalogram of the mounted models over that of the patient. It also reduces the chance of error during actual surgery by placing models in centric relation. Therefore, the possibility of intraoperative complications, and thus longer operating times, is minimized.

Vergence adaptation and the order of clinical vergence range testing.

When measuring horizontal relative vergence ranges, the conventional clinical procedure is to assess the base-in (or divergence) range before the base-out (or convergence) determination. The rationale for this order of testing is that the convergence responses stimulated during the base-out measurements may produce vergence adaptation (i.e., a fusional aftereffect), which may temporarily bias the subsequent base-in values in the base-out direction. However, the effect of reversing this order of testing (i.e, base-out before base-in) has not been directly evaluated. Accordingly, the present study compared distance base-in vergence ranges measured both before and after base-out testing at separate test sessions. Additionally, tonic vergence (TV) was assessed before and after each vergence range measurement. The results indicated that base-out vergence range testing stimulated vergence adaptation, and furthermore produced a statistically significant reduction in the subsequently measured base-in recovery value. However, the magnitude of this shift was less than the estimated degree of repeatability of the vergence range measurement. Therefore, a more appropriate order of testing would be to assess the heterophoria compensating range first in order to obtain accurate results during this more critical measurement.

The spiral curriculum in optometric education.

Optometric education should center around clinical training from the first year and develop within a spiral curriculum as far as possible. This does not eliminate the need for a layered curriculum where basic sciences are considered necessary to further learning but serves to make these sciences more applied and relevant to the study of optometry from the very beginning. A philosophy of science component requires to be integrated in the optometry teaching program so as to provide the student with as wide a range of thinking and problem-solving skills possible, in particular those which relate to optometry in general and clinical learning. Advanced technologies in the areas of computers and video materials as well as modern teaching strategies should be used to make paradigm changes in optometric teaching effective.

A case of pseudoankylosis between the pterygoid plate and mandible.

There are many causes of limitation of mandibular function. The use of CT scanning has enhanced our ability to look beyond the more obvious anatomic areas of mandibular ankylosis. An interesting case of pseudoankylosis of the pterygoid plate and mandible is presented. This case clearly demonstrates the importance of CT scanning in the diagnosis and treatment planning for such an unusual anomaly.

Paroxysmal nocturnal hemoglobinuria: report of case with odontogenic infection.

Paroxysmal nocturnal hemoglobinuria is characterized by chronic hemolytic anemia, leukopenia, and thrombocytopenia. The increased hemolysis and hemoglobinuria associated with sleep have been observed so frequently that these features have been incorporated into the syndrome's name. Infections, especially of the respiratory and urinary system, can cause hemolytic episodes. Patients with paroxysmal nocturnal hemoglobinuria have increased susceptibility to infections. Some PNH patients are leukopenic, but many are not. It has been reported that leukocyte alkaline phosphatase of granulocytes in patients with PNH is low. As Hartmann and Kohlhouse point out, "The principles of treating infection in PNH seem no different than the therapy of infections in any group. "If major surgery is indicated, preparation should include saline-washed red cells, which would increase the patient's number of circulating normal red blood cells, if necessary. The prognosis is variable. A small percentage of patients with PNH develop leukemia. However, in at least half of all patients, the number of complement sensitive cells decreases, and many of these patients live a fairly normal life.

Introduction of the sagittal symphysotomy in the treatment of chin deformities.

The management of chin problems occasionally presents a surgical problem to the clinician because of certain anatomic and clinical considerations. This article reviews and discusses some of the conventional surgical procedures in treating chin deformities. The new and versatile sagittal symphysotomy is introduced and described. Three case reports are presented.
