CLASSIFICATION OF DEFORMITIES To give correctly a classification of nasal deformities would simply mean to mention each anatomical part or division of the nose referring to the deformity involving the same. For this reason such an arrangement would be uselessly extensive, but for the proper recording of such cases the author advises a systematic method of nomenclature in which the deformity is stated, as: left, unilateral deficiency of inferior lobule; or right, median third deficiency of nasal dorsum of the parts destroyed and mentioned as such. [Illustration: FIG. 306.—DEFICIENCY OF SUPERIOR AND MIDDLE THIRD OF NOSE. (Saddle Nose.)] [Illustration: FIG. 307.—POST-ULCERATIVE DEFORMITY OF SUPERIOR THIRD OF NOSE.] [Illustration: FIG. 308.—LOSS OF RIGHT ALA, LOBULE AND COLUMNA.] [Illustration: FIG. 309.—LOSS OF LOBULE, INFERIOR SEPTUM AND COLUMNA.] A fair idea of typical deformities may be obtained from the following illustrations in which deformities from the milder to the most extensive extent are shown. The types here shown are all pathological with the exception of Fig. 306, in which a saddle nose is illustrated which may or may not be the result of disease or traumatism. [Illustration: FIG. 310.—ULCERATIVE LOSS OF RIGHT MEDIAN LATERAL SKIN OF NOSE WITH INVOLVEMENT OF ALA.] [Illustration: FIG. 311.—LOSS OF NASAL BONES AND PARTIAL ULCERATIVE DESTRUCTION OF DORSUM, LOBULE AND SEPTUM OF NOSE.] [Illustration: FIG. 312.—DESTRUCTION OF NASAL BONES WITH DORSAL INTEGUMENT AND LOBULE INTACT.] [Illustration: FIG. 313.—TOTAL LOSS OF NOSE.] Many other deformities of the nose exist, of course, such as lateral deviation, twists, etc., but as in most of such cases cosmetic rhinoplastic operations and subcutaneous injection are required for their correction, inasmuch as in these cases the skin is healthy and intact, they will be considered under that part of the chapter that has to do with purely cosmetic rhinoplasty or under the chapter on subcutaneous protheses. SURGICAL TECHNIQUE Before going into the individual methods involved in the correction of deformities of the nose, it is well here to go into the special details required for the performance of operations about the nose proper. =Anesthesia.=—It may be well here to state that many of the smaller or cosmetic operations can and should be done under local anesthesia, and that the anterior nares should be plugged to prevent the blood from running into the pharynx, but in operations of greater extent the posterior nares should be plugged by Bellocq or other method, and that since the patient must be placed under a general anesthetic, some special plan must be followed to give the same.
