Abstract

A method, and the apparatus for carrying out the method, for post-operative treatment of rhinoplasty patients. The method includes the preparation of a ''''before'''' cast of the patient''s nose and preparation of an ''''after'''' configuration or model of the nose so that the patient can see the expected results. One version of the method includes forming a progressive series of splints of differing contours intended to compensate for the reduction of swelling in the period following surgery, with these splints being formed to conform with the step-by-step models until the ultimate nose configuration is achieved. The method also contemplates securing the splints to the head of the wearer by a headband which would be of the cervical or low pull type so that proper pressure is applied by the splints during the time they are in place without causing discomfort to the wearer. The preferred form of splint contemplates using a universally adaptable form thereby precluding the necessity of ''''step-bystep'''' molding as previously stated.

ATTORNEYS RHINOPLASTY TREATMENT, METHOD, AND APPARATUS BACKGROUND OF THE INVENTION The invention, in general, relates to the medical field of rhinoplasty or plastic surgery relating to the nose and, in particular, relates to a system of predetermining the ultimate desired configuration of the nose following surgery and healing, and relates to methods of accurately and comfortably splinting the nose during the healing process.

DESCRIPTION OF THE PRIOR ART The following patent prior art is known to Applicant:

Lowman US. Pat. No. 1,062,654 l-Iilgers U.S. Pat. No. 1,378,455 Benjamin U.S. Pat. No.'l,7l5,027 Dawn US. Pat. No. 2,124,767 Kosior U.S. Pat. No. 2,882,892 Radewan US. Pat. No. 3,426,751 Grove US. Pat. No. 3,512,184

While a number of the above-noted patents do disclose various methods of making molds or casts of parts of the body to obtain a desired configuration, none of them appear to disclose a precise molding method and use contemplated by Applicant, and further none of them disclose the unique splinting structure and system, and none show the preferred universally adaptable form of splint contemplated by Applicant.

Applicant is also aware of the present method of post-operative treatment of rhinoplasty patients, which is to utilize a lightweight aluminum splint that fits over the nose and then is simply taped to the face. It is believed that this method is unsatisfactory primarily because it is very difficult to keep the piece in place due to movement on the part of the patient.

Further, the broken nasal bones are not stabilized to encourage rapid and proper healing as is the case in other cases of fracture treatment.

Additionally, there is no easy selectability of areas of needed pressure to properly assure the molding effect desired by the operation.

SUMMARY OF THE INVENTION This invention contemplates a method of first preparing a cast or model of the patients nose prior to surgery. A before and after model can then be obtained, and the before model can then be shaved or pared down to conform to the progressive reduction in swelling, which would normally be encountered following surgery, ultimately arriving at a final configuration for the nose which is the cosmetic object of the operation.

In conjunction with each trimming of this model, a plurality of splints are employed, and these splints can be contoured so that there will be a specific splint for each stage of the model. In this fashion it is contemplated that periodic visits of the patient to the surgeon will permit replacement of the splints on a regular and reducing basis so that they will closely conform to the desired configuration of the nose at the various stages of healing.

It is contemplated that the splints may be of either two-piececonstruction or may be of a preformed blank which can simply be heated and then formed to the desired configuration.

If a two-piece splint with opposed splint members interconnected by flexible cross-pieces is employed, the model can be eliminated and the progressive adjustment can be achieved by simply bending the crosspieces and/or heating and shaping the splint member.

It is further contemplated that the splints, in contrast to the prior art, would be held on the head of the user by utilization of a headband similar to that used in orthodontics, with the headband being of the cervical or low pull type or a combination high-low pull so as to securely hold the splints in place without discomfort to the patient and also so as to apply the pressure in the desired direction and on the desired areas.

Accordingly, production of a method and apparatus for carrying out that method of the character just described becomes the principal object of this invention, with other objects thereof becoming more apparent upon a reading of the following brief specification and claims considered in view of the accompanying draw- FIG. 1 is a perspective view showing the original casting made of the patients face.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS Considering first FIGS. 1 through 5 in describing the method of forming the moulage and the model, it will first be assumed that the patients face has been prepared by lubricating it with a suitable material to avoid harm to the face when the cast is made. Furthermore, a plastic airway 20 will have been placed in the mouth of the user. Following this, the exposed area of the face will be covered with one layer of a gauze impregnated with a suitable fast-setting material, such as alginate, and three additional layers of fast-setting plaster bandage will be applied. After the gauze-alginate and plaster bandage layers have set up, a moulage similar to that indicated by the numeral in FIG. 1 will be achieved.

Referring to FIG. 2, It will be seen that by reversing this moulage, a mold will, in effect, have been formed including depressed areas 11,1 1 for the eyes, 12 for the mouth, and 13 for the nose.

The next step in the method isto make the face models, paying particular attention to the nose area.

The models are formed by filling the moulage 10 with plaster and pouring it into the impression.

After the plaster has set, the impression or model is removed, and of course any number of such models can be obtained. At least one of these models, as shown in FIG. 3, will be the before" model, which shows the nose in its configuration prior to surgery. Furthermore, at least one of the models, as shown in FIG. 4, will be the after model which will show the nose in the configuration it is anticipated will be taken following completion of the surgery and the healing process. Any

- number of intermediate models could, of course, be

made if desired.

Turning first then to the form of the splint which would be used in conjunction with the model, attention is called to FIG. 13 where it will be noted that a preformed blank 50 of plastic or some suitable and which is bent or deformed in its central portion so as to provide raised areas 51,51 and a depressed central area 52 (see FIG. 14) is disclosed.

In this form of the invention the heating element, generally indicated by the numeral 70 is utilized. This heating element consists of a base 71, an electrical cord 72, and a heating chamber 73 which contains a plurality of heating coils 74,74. In utilization of the type splint disclosed in FIGS. 13 and 14, it is simply necessary to activate the heating device 70, place the blank 50 thereon and heat it until it becomes pliable; Following this it would, of course, be placed over the model and contoured to the desired configuration.

In this regard, one splint will be formed, and then the model will be pared down to represent the first stage of swelling reduction and another splint will be prepared. This process can be repeated as often as the surgeon thinks necessary until the after configuration is arrived at, with the series of splints so formed being fitted to the patient during periodic follow-up visits.

After the splint is formed, it is then necessary to apply a restraining member 60, as shown in FIG. 17, which has its central portion 62 received in the depression 52 of the blank, and with the ends 61,61 being secured to a resilient member (not shown) which passes around the head as will be described below with regard to FIG. 6.

FIG. 18 shows a top view of the splint of FIG. 17 with the restraining member 60 in place.

FIG. 16 shows a similar splint assembly except that the restraining member 160 is integral with the blank 150. Again the blank or blanks would be heated and then shaped to the desired configuration as described above in connection with the blank of FIGS. 13 and 14. It will be noted that the restraining member 160 is deformed at 162,162, and the purpose of this is to avoid obscuring the wearers field of vision.

Turning next then to FIG. 6 for a description of a modified form of splint, it will be seen that the splint shown in that figure consists of a pair of opposed splint members 30,30 of plastic or similar material which have an arched connecting wire 31 embedded in them and which also have, on their outer surfaces, a plurality of locating notches 32,32. The splint is, of course, held in place on the face of the wearer by the holding member 40, which is a wire member bent back upon itself at its ends 42,42 and having a V-shaped central portion 41. Secured to the holding member 40 is a cross-piece 43 which will fit into the locating notches, and in this I regard it is contemplated that, depending upon where the most pressure is desired, the cross-piece 43 can be selectively located in any of the notches 32,32.

The holding member 40 has its ends 42,42 connected to an elastic member 44,44 which is similar to the headband of an orthodontic cervical type which passes around the head of the wearer and can be adjusted to securely hold the splint in place.

FIG. 8 shows a modified form of the splint with a pair of opposed splint pieces 130,130 containing the locating notches 132,132, but also in this case having two connecting members 131 and 131a embedded therein.

FIG. 11 shows a splint similar to that shown in FIGS. 6 trough 10 with central portion bent down as a modified form of restraining member 240. This member is similar to that of FIG. 6 but has its to at 241 to minimize visual obstruction to the wearer. In using this form of splint, it is simply necessary to place it over the selected model and then deform it to the desired configuration, with it being understood again that it is contemplated that a progressive series of splints will be used during the healing process.

In this form of the invention the model is not required. The splint can be deformed to conform to the nose configuration at the various stages of healing by simply deforming the cross-pieces 31, 131, or 231, as shown in FIG. 10, for example.

It is also possible to modify the configuration of the splint members 30,30, 130,130, and 230,230 if desired by heating them until they become pliable and then shaping them as desired.

It is submitted, therefore, that a unique, practically fool-proof method of post-operative rhinoplasty care and the apparatus for carrying out that method have clearly been set forth above. By this method the surgeons time is believed to be reduced inasmuch as most of the steps, except actually shaping the models, can be handled by para-medical personnel. It is also believed that the patient gains an advantage from this system in that he is able to see the ultimate desired result before surgery is performed, and further the patient is believed to benefit because of the increased comfort since it is believed apparent that applying splints in the fashion described herein would definitely result in improved comfort over the present tape-on method. Additionally, there is assurance that theproper molding and splinting pressures achieve the desired end result.

While a full and complete description of the invention has been set forth in accordance with the dictates of the Patent Statutes, it is to be understood that modifications can be resorted to without departing from the spirit hereof or the scope of the appended claims.
