Reproducibility of aimed-at profiles.

Would a surgeon always draw the same aimed-at profile when planning the correction of a face with evidently malpositioned jaws? The same 10 profile lines were given to seven maxillofacial surgeons on two occasions at intervals of 6 months. The differences in absolute and proportional vertical measurements were compared. It is shown that the variations between first and second drawing were quite large for individual values. However, even the mean differences per measurement vary between surgeons from 0 to 10%. The drawings for the whole group corresponded reasonably well with the ratios given by Farkas and Munro (1987) but were rather divergent from the 'golden dimensions' proposed by Brons and Mulié (1993). Considering the sometimes significant differences, one is advised not to draw profiles 'off the cuff' but to use a construction system for planning osteotomies.

Profiloplasty: variations in personal views.

There is sometimes controversy among colleagues over treatment plans in orthognathic surgery. This is because there are differing ideas about which part of the facial skeleton should be moved to give an optimal result. A study was therefore set up to obtain insight into the differences between surgeons. Ten unbalanced profile drawings were given to seven experienced surgeons with the request that they draw the profile line which they would like to give these patients. It was acceptable either to draw the profiles 'artistically' off the cuff or to use additional construction lines as long as this was not the profile planning according to Brons and Mulié (1993). The evaluation showed that some surgeons drew profiles which resembled each other to some extent in proportions and inclinations, while others produced variations without any evident regularity and basic concept. The variability per profile was very important in almost all cases. Such discrepancies are not acceptable in a teaching centre.

Differentiation of multiple giant cell lesions, Noonan-like syndrome, and (occult) hyperparathyroidism. Case report and review of the literature.

The history is reported of a boy known to have von Recklinghausen neurofibromatosis and multiple recurrent central giant cell granulomata of the mandible and maxilla. This paper discusses the problem of differentiating multiple central giant cell granulomata, Noonan-like/multiple giant cell lesion syndrome, and brown tumor resulting from (occult) hyperparathyroidism.
