Abstract. A cartilage graft from the cartilaginous hump can be used in primary rhinoplasty for nasal tip projec- tion. This technique has now been used for two years without complications in 35 patients with similar nose deformities, which included an inadequately projected tip and a high dorsal line. These grafts have proved to be another easy way to get an adequate tip projection in primary rhinoplasty.

Key words: Rhinoplasty - - Cartilage - - Graft - - Tip

To get an adequate nasal tip projection, the advan- tages of cartilage grafts in primary rhinoplasty, are well known. The use of these grafts have been widely popularized by several authors [1, 4, 5, 6].

Jack Sheen is one of the most enthusiastic pro- moters in the use of these grafts. He describes in his book, Aesthetic Rhinoplasty [7], a deformity called tip inadequately projected (TIP). in it he also men- tions that a cartilage graft can be used to produce a well-projected nasal tip.

In Mexico, the so-called Mestizo nose, shows several problems as perfectly described by Monas- terio and Olmedo [3]. They provide solutions for the correction of this nasal shape and procedures to get a satisfactory final result.

The characteristics of this kind of noses can be classified among the TIP deformity group described by Sheen. Frequently, this deformity includes a high dorsal line with a hump mainly formed of carti-

lage from the septum in conjunction with the upper lateral cartilages.

In Skoog's rhinoplasty technique [8], a big piece of the osteocartilaginous hump is resected in one block and reapplied once it has been reshaped and reduced in size, obtaining a better profile line. Based on this type of hump resection in block, but conservatively resected, it is possible to obtain a quadrangular piece, mainly of cartilage. This piece, if properly shaped, can be used as a graft for the nasal tip.

In this article, we are reporting on our experience with the use of grafts obtained from the cartilagi- nous vault, for projection of difficult nose tips in primary rhinoplasty.

Thirty-five patients, selected with similar charac- teristics, were operated on between November 1980 and September 1982. The most important defect in all o f these patients was a poorly projected tip or a tip with a bad definition and a predominantly carti- laginous high hump.

A conservat ive rhinoplasty was performed on each patient [2]. The osteocartilaginous hump was resected in one piece with the use of a No. 11 blade. At this stage the cartilaginous portion of the upper lateral cartilage was removed. We finished the re- section with a chisel, removing a very small part of bone. This specimen was cleaned of small amounts of at tached soft tissue and at the same time taking care to preserve the perichondrium. The bony por- tion was detached and any possible residue of nasal mucosa was eliminated from its under surface. A supramucosal resection of the hump is recom- mended in big noses. Following this, a proper graft for each case was designed. In most cases a triangu- lar-shaped graft can be tailored to measure 2 cm by 8 to 10 mm on its base (Fig. 1). Its upper surface has a little convexity, avoiding the shape edges of the

graft. The undersurface has a central projection (Fig. 2) that corresponds to the septum. This projec- tion can be preserved to facilitate graft fixation.

The graft was applied in the nasal tip in the usual way, through a marginal incision (Fig. 3). The pocket formed to contain the graft can have a groove between the medial crura of the alar carti- lages where the undersurface edge of the graft can lie. This edge rests on the groove, secures the posi- tion of the graft, and avoids any displacement (Fig. 4).

The postoperative results have been very satis- factory, as far as the rhinoplasty is concerned. The graft has not had any displacement in any case; there has also been no reabsorption, probably be- cause the perichondrium attached to the surface en- sures the survival of the graft, and finally the shape and projection of the tip has been very adequate in all cases (Figs. 5-8).

Discussion and Conclusions

A well-projected nasal tip can be obtained, in some nasal deformities; with cartilaginous grafts, as is ev- idenced with this group of selected patients. Fur- thermore, the use of part of the cartilaginous hump as a graft demonstrated the following advantages:

1. It is not necessary to touch or modify other structures such as the nasal septum or the concha of the ear.

2. It saves time. There will not be an extra surgi- cal stage because the hump resection is a necessary step in conventional rhinoplasty.

3. The graft has perichondrium on its anterior surface, which ensures its survival.

4. The graft shape helps its adequate placement. Its edges are slightly convex avoiding abrupt de- marcation. The presence of the septal projection on the back surface places the graft between the medial

crura of the alar cartilages. This septal projection avoids future displacement and malposition.
