NEUNER, M.D. Department of Maxillo-Facial Plastic Surgery, University of Berne, Switzerland THE nasal hump consists of varying amounts of the osseous and cartilaginous dorsum of the nose and its removal is generally carried out by chisel, saw, rasp, osteotome or bone cutting forceps. It is almost always necessary to infracture the nasal bones for Fro. I, A One of the set of four forceps which have been developed for nasal hump removal. msthetic reasons as well as closing the open bony roof of the nose. When the mobilised bone segments are shifted medially, however, the dorsum of the nose is raised somewhat. While this is welcome in the treatment of saddle nose, it must be compensated for in obtaining the desired profile line in nasal hump corrections. 375

2 376 BRITISH JOURNAL OF PLASTIC SURGERY In the IO years during which we used saws for hump reductions, we always had some difficulty in obtaining the desired concavity and in making this compensation; nor did the use of a chisel and straight bone-cutting forceps (Kazanjian and Converse, 1947; Rowland, 1955) eliminate the problem. We have therefore developed a set of bone-cutting forceps with blades of varying curvature (Neuner, 197 o) so that the precise concavity desired can be given to the nasal profile (Fig. i). The appropriately curved forceps is selected pre-operafively from the FIG I~ B FIG I~ C Fig. B to D.--B~ C and D, The curvature of the blades is varied and the appropriate forceps chosen pre-operatively from a profile radiograph. FIG I, D study of a profile radiograph, taking into account any elevation of the bridgeline which might occur on infracture. As a rule men prefer a straight or occasionally even a slightly hooked nose ; women prefer a more concave profile. Operative Technique.--The new nasal profile is first marked on the skin, which is then undermined ill the usual way through two intercartilaginous incisions. The lateral triangular cartilages are separated from the anterior border of the septum. The selected forceps is now guided through the intercartilaginous incision and appropriately placed beneath the external skin marking (Figs. 2 and 3). By closing the forceps the cartilaginous and bony hump can be separated as one piece (Fig. 4). If required, one can use the cartilage from the excised hump as a free transplant in the lower lip for the

The whole hump can also be implanted in the columella and the tip of the nose elevated somewhat, particularly in cleft lip and post-traumatic deformities ; the bony portion is set on the anterior spine and the cartilaginous part is pushed forward between the two Mar cartilages so that the nasal tip remains elastic and the bony base unites with the spine.

An oblique osteotomy is now made across the nasal root using the circular saw developed by the author (Neuner, I966) (Fig. 5). The lateral osteotomy is carried out through an incision in the canine fossa. Usually the straight, hollow-ground saw is used for this. If a curved effect is desired or additional nasal root correction is needed, we use our own specially developed drill (Neuner, I966) (Fig. 6). In addition to the osteotomy

We have been using this method for about 5 years and have operated on about 13o cases during this time. All operations proceeded without complication. A FIG. 7 A~ Pre-operative.

Four patients required further correction of minor irregularities on the dorsum. Summary.--A procedure for the correction of the excessively aquiline nose is presented in which the hump reduction adheres strictly to a pre-operatively decided profile. A set of specially developed forceps is described with which the osseocartilaginous hump can be removed in one piece and, if necessary, be set as a free implant into the upper lip or columella. The remaining osteotomies are completed with
