Revision rhinoplasty. An analysis of aesthetic deformities.

Revision rhinoplasty can present difficult and challenging problems, which maximally test the skill and judgment of the facial plastic surgeon. We conducted a retrospective study of 1221 consecutive rhinoplasties, of which 170 were revision procedures. The rate of revision of our own procedures is 5.3%. Postrhinoplastic deformities are divided anatomically into the upper, middle, and lower thirds of the nose. The largest category of deformities occur in the lower thirds of the nose, in which bossa are the most common problem. Overall, pollybeak is the most common deformity in 33% of the procedures performed, followed by bossa in 26%, and excessive dorsal removal in 24%. We analyzed the causes and selected management of these cases.

A maneuver to improve the nasal airway.

The functional sequelae of rhinoplastic surgery are emphasized and the functional and anatomical causes of postoperative nasal obstruction are discussed. A maneuver to improve the airway and decrease the incidence of postoperative nasal obstruction is presented.

Sequential rhytidectomy.

An alternate technique of rhytidectomy is described. After adequate undermining, hemostasis and imbrication, the skin flaps are rotated and advanced with sequential tension in contrast to the use of bipolar or tripolar anchoring points. They are then trimmed and sutured in a step-like sequential fashion starting at the temporal incision and proceeding around the ear to the occipital area. The technique has been used in over two hundred patients during a two-year period. The results have been encouraging in eliminating dog-ear formation, excessive tension on wound edges, and step deformities of the hair bearing tissues. A discussion of the advantages of the method and a comparison with other techniques is outlined.

Experience with gel-filled implants in augmentation mentoplasty.

Many materials have been used for augmentation mentoplasty with varying degrees of success. In our experience with the silicone bag-gel implant in 50 cases over the past 18 months the results have been quite satisfactory and there were no untoward complications.

Double lateral osteotomy in rhinoplasty.

Double lateral osteotomy has proved to be useful in the management of broad, thick, and heavy maxillary processes. The technique of performing two lateral ostotomies and the indications for its application are described. The results obtained from cadaver dissection and clinical experience with this technique are discussed.

Gelatin film. A useful adjunct in rhinoplastic surgery.

Gelfilm is a nonporous, rigid, cellophane-like absorbable gelatin. Its use in preventing adhesions in neurosurgery and ophthalmic, otologic, and chest surgery has been well described. It has not been previously reported for nasal surgery. It incorporates many characteristics of an ideal absorbable implant. The material has been used clinically as a dorsal nasal implant either alone or as a vehicle for autogenous cartilage grafts. Its main function is to diminish adhesions between the nasal bones and dorsal skin after surgery on the nasal pyramid. Its benefits seem most applicable in traumatic or revisionary rhinoplasty. Its use has been well documented in 40 cases with a one-year follow-up. The only disadvantage is a slight prolonged dorsal edema until the implant resorbs. The results have been impressive in both early and late postoperative follow-up because the nasal dorsum appears smoother and the skin nonadherent.

Proplast chin augmentation.

A method of chin augmentation employing a newer synthetic material (Proplast) is presented. The characteristics and biocompatibility of Proplast are detailed. Technical considerations and results of short term clinical trials in 20 patients are discussed. One implant necessitated removal secondary to trauma four months after surgery. All other implants including over 30 additional cases have been without incident.

Infrabrow lift.

The infrabrow lift is presented as a specific method to correct skin redundancy between the eyebrow and upper lid. Indications are outlined which differentiate this technique from the suprabrow surgical approach. The surgical technique is discussed. Esthetic results have proven most satisfactory.

An absorbent, non-adherent nasal pack.

A modification of an absorbent, non-adherent material (Telfa) is described for use as an anterior nasal packing. The ideal nasal packing should fulfill certain criteria. It should be easy to introduce and remove, contour to the nasal cavity to exert a tamponade effect, and should not prolapse or react unfavorably with the mucous membranes of the nose. The advantages of Telfa as a nasal packing is discussed and compared to previously described materials in this regard. During the past three years this pack has been used in over 800 patients for anterior epistaxis, septal and rhinoplastic surgery. The results have been extremely satisfactory, and the authors suggest their use in these cases.

The conservative management of the Negro nose.

The difficulties in obtaining an adequate result in the Negroid nose have been elucidated by other authors. Paucity of lobular cartilage; the flat dorsum; short columella; wide flaring nares; and skin that tends to keloid formation have led many surgeons to attempt radical surgical techniques to obtain rather limited results. To circumvent the complications in the more radical procedures, a more conservative concept of an entirely intranasal operation without external skin incisions is outlined. This technique consists of tip rotation andlobular cartilage trimming; the use of a non-absorbable basal bunching suture, and the placement of a dorsal implant without performing osteotomies. A comparison with other techniques is made, as well as surgical aims, limitations and a discussion of results. Pertinent illustrations and photographs are presented.
