A specific and somewhat elaborate classification has been given to the more important and distinctive deformities of the nose, principally to facilitate the proper citation and recording of cases.

It may be readily understood that each one of these classifications may be further subdivided, but such subdivision can be only of the degree or extent of the deformity, and must be left to the individual operator and his thoroughness of observation and nicety of recording.

The author prefers making a plaster cast of the entire nose which is to be corrected, and a second cast after the operation has been completed, or at the time of his discharge. A record sheet, or a direct photograph, can be made before and after operation for the same purpose, which is not so desirable, however, because it has been found quite impossible to procure the desired accurate pictures of a nasal deformity, the photographer not being given to bringing out imperfections as the surgeon wishes them, even under the most explicit instructions, unless the surgeon accompanies the patient to the studio to supervise the posing. This requires a waste of valuable time; not to speak of the expense of making pictures of a pathological nature. The better way would be to have an apparatus in the operating room. The surgeon can then pose his patient against a screen background in the position and to the size of picture he may desire. Plate cameras and time exposures are best for this purpose. For recording and half-tone reproduction silver prints are found best.

For all deformities of the anterior nasal line a hydrocarbon compound of the higher melting points should be used. This should be injected in the cold form. The mixture given on page 39, with perhaps an added half dram or dram of paraffin, has been found excellent, the addition of paraffin being made to assure a suitable fineness of contour and width. The softer mixtures are more liable to cause a lack of contour and a consequent widening of the part injected, even after molding, because of the contractility of the skin overlying the injected mass, which tends to flatten it out, giving the nose a less artistic and delicate appearance.

Furthermore, a soft mixture will be found to be inefficient in overcoming the tension of the skin in most cases, especially those about the middle third of the nose.

In some cases of lateral deformity, and where otherwise mentioned, it is advisable to use only a mixture of the lower melting points, as in the case in the correction of interciliary furrows and temporal muscular deficiency.

Superior Third Deficiency.—The degree of depression about the superior third or root of the nose varies considerably. The most extensive form may be commonly found in the negro nose, where there is almost an absence of a rise in that part of the nasal bones. Such noses are also found in the Chinese and Japanese. The condition ofttimes may be associated with epicanthus.

Epicanthus, formerly corrected by an elliptical excision done anteriorly, can be entirely overcome by the subcutaneous injection method, thus not only avoiding the resultant linear cicatrix, but building up the depressed nose to its normal contour.

The skin overlying most of the defects of the superior third is usually found to be loose, hence injection is readily accomplished.
