Let the author warn the operator against the “beauty cranks,” especially of those who are just about to engage in great theatrical ventures, circus performances, or “acts,” and very desirable marriages. These are patients who are not only difficult to deal with, but the first to harm the hard-earned, well-deserved reputation of the surgeon and to drag him into courts for reimbursement for all kinds of damages, especially backed up by events, losses, and sufferings largely imaginable and untrue, and ofttimes entirely impossible. In all cosmetic surgery this branch is the most dangerous from that point of view; therefore the operator should take his case well in hand, proceed with an unshakable determination and give the patient to understand his position, even to explaining what disappointments there might be and what dangers, if any, he might look forward to. The author believes it no unjust demand to have an agreement made with the one to be treated in which these matters are fully considered. Such an arrangement will save him much worry and will tend in the majority of cases to keep his patient satisfied. On the other hand, the operator should not undertake to do an operation of a cosmetic nature unless he has a fundamental and practical experience of long standing in this branch of surgery, and is ready at all times to cope with such post-operative conditions as are likely to arise, which will be described later. The author has on various occasions been asked to correct the most hideous malformations of parts of the face, particularly the nose, in which surgeons of high standing, both here and abroad, had injected paraffin in liquid form, usually under a general anesthetic, the most remarkable being that of a hospital orderly in the United States service, who had been subjected to not only one of such injections to correct a saddle nose under chloroform anesthesia, but to three distinctive operations, with the result of a permanent disfigurement, bettered only by a succession of excisions at different parts of the nose. Apropos of such cases it may be timely to state that a general anesthetic for the performance of a prothetic injection operation is never justifiable and should be considered a lack of knowledge on the part of the operator, unless its use be advised by another surgeon in consultation. The greatest mistake made with this so-called “filling method” has been a desire on the part of the patient or the operator, or both, to complete the work too quickly. Unscrupulous operators have restored a saddle nose or the contour of the cheeks in a few minutes, when it is an established fact that the work should be done slowly, giving time for the injections to accommodate themselves and to organize before others are attempted. This is not only true of fillings about the cheeks and shoulders, but also of injections about the nose and forehead.
