The needle should be introduced laterally and anterior to the angular vessels to prevent their occlusion and injection. The point of selection is made at about the middle of the deformity. The needle is introduced until its point lies in the center of the depression, or at the median line from the anterior view. The mass is injected slowly as the skin of the nose is pinched up between the forefinger and thumb of an assistant. The part is injected until a tumefaction, equal in body to the extent of the deformity, is attained. The needle is allowed to remain in place for a moment, to permit of a stoppage of the threadlike mass, usually following the pressure applied to the piston, after the operator has stopped turning the screw. This will prevent the mass from following into the channel made by the needle, or the backing up of the mass, as it were. Should this occur the paraffin mixture should be squeezed from the skin opening to prevent the formation of an intercutaneous encystment. Immediately the needle is withdrawn the operator places a finger tip over the opening and proceeds with the thumb and forefinger of the right hand to mold the mass into the desired shape. The post-operative treatment should be as previously given, and is the same with all injections about the nose, so that it will not be referred to again under this heading. While a fairly large defect can be corrected at one sitting, it is advisable to rather reinject one or two weeks later to secure the exact shape. It is to be impressed upon the operator that there is always a slight broadening of this part of the nose following the development of the connective tissue which takes the place of the injected mass, hence the injection should not be overcrowded nor the parts overcorrected. The mass should be molded out as narrow as possible and be pinched between the fingers by the patient two or three times a day after the reaction has subsided, which is usually about the third day. This procedure will keep the mass from being flattened during the time tissue replacement takes place. =Middle Third Deficiency.=—This defect is commonly seen in football players and pugilists as the result of a breaking of the inferior extremities of the nasal bones and the displacement of the articulating cartilages, although the defect is often seen as a result of an injury to the nose early in life, causing a lack of development in the superior or articulating extremities of the cartilages. Nondevelopment from catarrh, syphilis, and intranasal disease are other causes. This type of deformity is generally designated as the saddle nose. In the latter cases the skin is usually bound down to the cartilaginous structure by cicatricial bands, and needs to be liberated. This is accomplished subcutaneously with a fine tenotome introduced laterally.
