Dynamics of rhinoplasty

Nasal dynamics were studied on 87 patients undergoing rhinoplasty of one zone or two distant nasal zones. Statistical analysis of the result revealed that reduction of the nasion area, besides setting the soft tissue back, gave the appearance of increased intercanthal distance and lengthened the nose. Reduction of the nasal bridge resulted in a wider appearance on front view and a cephalically rotated tip on profile. Augmentation of the bridge affected the nose reversely. Tip cephalad rotation was achieved by resecting one of the three areas: the cephalad portion of the lower lateral cartilages (affecting the rims more), the caudal septum (affecting the central portion more), and the caudal portion of the medial crura of the lower lateral cartilages (affecting the central portion only). Resection of the alar base not only narrowed the nostrils but also moved the alar rim caudally. Furthermore, it reduced tip projection when a large alar base reduction was done. Reduction of the nasal spine increased the upper lip length on profile and reduced tip projection when a large reduction took place. Significant reduction in caudal nose projection resulted in widening of the alar base.

Alar rim lowering

A technique for the lowering of the alar rim is presented. The indications for this technique, originally presented by Meyer and Kesselring, have been expanded to other related nasal deformities, including the high-arched nostril, the asymmetrical nostril, the Mestizo nose, and the hanging columella, in which the surgeon feels that total nasal length should not be sacrificed. The technique consists of an incision parallel to the alar rim and an unfurling of the vestibular mucosa caudally. A cartilage graft from the septum, lowering lateral cartilage, or other source is placed between the two layers at the newly proposed alar height. Through-and-through sutures hold the graft and alar rim in place.     

Surgical correction of burn deformities of the nose.

We present a method for reconstruction of the everted nostrils of the burned nose. Through a "ram's horn" incision, the everted vestibular lining and lower lateral cartilages are mobilized and repositioned, and the resultant defect is covered with a full-thickness skin graft. The linear scar is created as part of a circle, so that the postoperative contracture will improve the alar contour.     

The hanging ala

The relationship of the alar rim to the columella can be altered during rhinoplasty. This may be especially true when a long nose has been shortened. In thin-skinned individuals, elevation of the ala may be accomplished by resection of the caudal aspect of the lateral crus without trimming the lining. In thick-skinned individuals, elevation of the ala may be accomplished by resection of the nasal lining at the cephalad border of the alar cartilage.     

Lifting of the upper lip: personal technique

The authors illustrate a personal technique for lifting of the upper lip with augmentation of the lower lip. With this procedure, a shortening of the "prolabium," an increase of the vermilion, and a natural, nicer mouth are obtained, with the possibility of increasing the volume of the lower lip simultaneously. The operation is carried out as outpatient surgery using local anesthesia, with intravenous sedation if requested. Incisions are made bilaterally beginning at the alar fold of the nose; they then enter the nostrils and rise medially on the skin below the lower margin of the medial crura of the alar cartilage. In this way, the columella is safe, and there are no scars. Then, the two pieces of excess skin and a small, whole strip of orbicular muscle can be cut away, just under the nose. If the goal is to better extrude the vermilion, the skin as far as the Cupid's bow also has to be undermined; if the goal is to shorten the prolabium, a slightly wider amount of orbicular muscle can be removed. The muscle is suspended to the base of the nose with interrupted stitches (absorbable 4-0 suture), the subcutaneous tissue is sutured, and finally the skin is closed with a running suture. The removed muscle is a good graft for increasing the size of the lower lip.     

Valvular obstruction of the nasal airway.

Valvular nasal obstruction may occur in the postoperative rhinoplasty patient. One may anticipate a dropping of the tip, from residual redundant or inelastic skin, in some older patients with long noses. Measures to correct (or avoid) this may be undertaken at the time of the primary rhinoplasty. However, an overcorrection may be necessary if there is much redundant skin. Discretion may indicate the need for a secondary procedure. Lateral wall valving is unusual-but it may occur in the long, high, thin nose (where a suggestion of this action may be observed preoperatively). Maintenance of continuous cartilage along the alar rim, at the time of alar cartilage resection, appears to be important in prevention of postoperative valvular obstruction in these few patients.     

A rotational method of bilateral cleft lip nose repair

Repairs of the bilateral cleft lip nasal deformity have focused on lengthening the lower columella by adding lip, nasal structure, or a piece of ear. In these methods, the raised true columella worsens the dorsal dislocation of the lateral crura of the alar cartilages and the lateral and dorsal displacement of the alar domes. We believe that lengthening the upper columella from above is more anatomic and reasonable than lengthening the lower columella. A method for reconstructing the upper columella by medial and ventral rotation of the dislocated alar domes is described. Figi's "flying bird" incision was extended to the columellar base along the nostril margin. Through this incision, the lower one-third of the nose, including the alae and nostril floors, was undermined widely. The inner layers, the nostrils, were freed from the surrounding tissues, except in the region of the columella and the septum, and rotated medially in the opposite direction of Cronin's technique. The resulting nasal shape, involving the columellar length and the concavity between the nasal tip and lateral ala, improved in 11 patients.     

Columellar elongation in bilateral cleft lip repair: early results.

Flattening of the nasal tip and shortness of the columella are two of the deformities that remain following successful repair of a bilateral cleft of the lip. Until now, correction has not been possible without producing undesirable scars on the surface of the nose or lip. A three-dimensional Z-plasty on the alar rim achieves columellar lengthening and forward projection of the tip, but it does not have these disadvantages.     

The alar contour graft: correction and prevention of alar rim deformities in rhinoplasty

One of the most common problems affecting both the primary and secondary rhinoplasty patient is deformity of the alar rim. Typically, this deformity is caused by congenital malpositioning, hypoplasia, or surgical weakening of the lateral crura, with the potential for both functional and aesthetic ramifications. Successful correction and prevention of alar rim deformities requires precise preoperative diagnosis and planning. Multiple techniques of varying complexity have been described to treat this common and challenging problem.Over the past 6 years (1994 through 2000), the authors have employed a simple technique in 123 patients for alar retraction that involves the nonanatomic insertion of an autogenous cartilage buttress into an alar-vestibular pocket. Among the 53 patients who underwent primary rhinoplasty in this study, 91 percent experienced correction or prevention of alar notching or collapse. However, correction was achieved for only 73 percent of the patients who underwent secondary rhinoplasty; many of whom had alar retraction secondary to scarring or lining loss. In patients with moderate or significant lining loss or scarring, a lateral crural strut graft is recommended. The alar contour graft provides the foundation in the patient undergoing primary or secondary rhinoplasty for the reestablishment of a normally functioning external nasal valve and an aesthetically pleasing alar contour. This article discusses the anatomic and aesthetic considerations of alar rim deformities and the indications and the surgical technique for the alar contour graft.     

Use of a temporoparietal fascia-covered silastic implant in nose reconstruction after foreign body removal

A total of 47 consecutive patients with paraffinoma of the nose underwent surgery for paraffinoma removal and insertion of temporoparietal fascia-covered Silastic implants between January of 1990 and June of 1996. There are several advantages to our procedure, and we obtained satisfactory outcomes with it. A bilateral alar rim incision was sufficient for our procedure. The Silastic implant could be sculptured easily, was not absorbed, and produced excellent cosmetic results. The fascia was highly bioadaptable and survived beneath the dermis through revascularization, even in the places where the paraffin material remained. The fascia reinforced the thinned skin that resulted after paraffinoma removal and, therefore, prevented exposure of the Silastic implant. The telangiectasia of paraffinoma of the nose improved in some patients after surgery.     

Nasal tip sutures part II: the interplays

The achievement of consistently superior results in rhinoplasty is rendered difficult in part by a number of complex interplays between the anatomical structures of the nose and the techniques used for their alteration, such as tip sutures. The effects of sutures depend largely on the magnitude of suture tightening, the intrinsic forces on the cartilages, cartilage thickness, and the degree of soft-tissue undermining. The tip complex is perhaps the most intricate of the nasal structures, exhibiting subtle but evident responses to manipulations of the lower lateral cartilages. The three-dimensional effects of nine suture techniques that are frequently used in nasal tip surgical procedures are discussed and illustrated. (1) The medial crura suture approximates the medial crura and strengthens the support of the tip. The suture also has effects that are less conspicuous immediately. There is slight narrowing of the columella, caudal protrusion of the lobule, and minimal caudal rotation of the lateral crura. (2) The middle crura suture approximates the most anterior portion of the medial crura. There is greater strengthening of the tip and some approximation of the domes with this suture. (3) The interdomal suture approximates the domes and can equalize asymmetric domes. However, the entire tip may shift to the short side if there is a significant difference in the heights of the domes because of short lateral and medial crura. (4) Transdomal sutures narrow the domal arch while pulling the lateral crura medially. The net results are increased tip projection, alar rim concavity, and the potential need for an alar rim graft. In addition, depending on suture position, cephalic or caudal rotation of the lateral crura may be observed. (5) The lateral crura suture increases the concavity of the lateral crura, reduces the interdomal distance, and may retract the alar rims. Perhaps the most significant inadvertent results of this suture are caudal rotation of the tip and elongation of the nose. This is important because patients who undergo rhinoplasty would often benefit from cephalic, rather than caudal, rotation of the tip. (6) The medial crura-septal suture not only increases tip projection but also rotates the tip cephalically and retracts the columella. (7) The tip rotation suture shifts the tip cephalad while retracting the columella. (8) The medial crura footplate suture approximates the footplates, narrows the columella base, and improves undesirable nostril shape. (9) The lateral crura convexity control suture alters the degree of convexity of the lateral crura. The nuances of these sutures and their multiplanar effects on the nasal tip are discussed.     

Alar rim deformities

Alar disharmony is one of the most common abnormalities observed after a rhinoplasty. This article describes three classes in addition to Gunter's classifications of alar/columella deformities, which include concave ala, convex ala caused by convex lateral crus, and convex ala caused by thick alar tissues. These deformities are best visualized from the basilar view. The different surgical techniques for correction of true alar abnormalities are presented. The alar convexity, when it is the result of a misshapen cartilage, is corrected using a lateral crura spanning suture, posterior transection of the lateral crura, or transdomal suture. A thick ala, resulting in convexity, can be thinned through either a direct incision on the ala or an incision in the alar base. A lateral crura strut, an onlay graft, or a rim graft eliminates the concavity. For a slight retraction, an alar rim cartilage graft is an optimal choice. For significant alar retractions, the author's preferred technique is an internal V-to-Y advancement, which is described in detail. An elliptical excision of the alar lining will effectively correct the hanging ala. These techniques have been used to correct alar disharmonies on 58 patients. One patient from the V-Y advancement group exhibited a small area of alar necrosis, and two early patients demonstrated an overcorrection; all were easily resolved with revision surgery. By carefully identifying nasal base and alar abnormalities, harmony can be established to correct an undesirable appearance.     

Indications and use of composite grafts in 100 consecutive secondary and tertiary rhinoplasty patients: introduction of the axial orientation

The fragile alar rims are complex structures whose specialized and supportive skin ensures the competence of the external valves and the patency of the inlets to the nasal airways. A chart review was performed of 100 consecutive secondary or tertiary rhinoplasty patients in whom the author had placed composite grafts before February 1999. Follow-up continued for at least 12 months. In 94 percent of the patients, composite grafts were harvested from the cymba conchae by removing the cartilage with its adherent anterior skin. In 6 percent of the patients, independently indicated alar wedges supplied the grafts. Six patients required secondary procedures to thin the alar rims, but such revisions have not been necessary since primary contouring of the cartilaginous graft component was instituted. Three auricular donor-site complications (one keloid, two thickened graft contours) were successfully revised through office procedures. Prior cosmetic rhinoplasty in a patient with normal alar cartilage anatomy exceeded all other etiologies as the cause of the deformity for which composite grafts were indicated (50 percent). The second most common etiology was deformity from prior rhinoplasty in a patient with alar cartilage malposition (33 percent of patients). Congenital deformities (7 percent of patients), trauma (6 percent), and prior tumor ablation (4 percent) comprised the remaining etiologies. Composite grafts were used most frequently to correct alar notching or asymmetry in rim height (43 percent of patients) or to provide an increase in apparent or real nasal length (28 percent). External valvular incompetence (14 percent of patients), nostril or vestibular stenosis (11 percent), or combined vestibular stenosis and lateral alar wall collapse (4 percent) were less common indications. Most composite grafts were oriented in the coronal plane (parallel to the alar rims). However, nostril or vestibular stenosis was corrected by sagittally placed composite grafts, and a third orientation (axial plane), to the author's knowledge not described previously, was used in patients with combined nostril stenoses and flattening of the alar walls. In this secondary rhinoplasty series, iatrogenic alar rim deformities or stenoses following cosmetic rhinoplasty dominated other causes requiring composite graft reconstruction (83 percent of patients). Of these 83 patients, 39.7 percent had preexisting alar cartilage malpositions, further supporting the importance of making accurate anatomical diagnosis part of every preoperative rhinoplasty plan.     

A simple method for alar rim reconstruction

A one-stage repair procedure is described for the reconstruction of small to medium-sized full-thickness alar rim defects with a hinged medially based nasolabial island flap. The operation is performed under local anesthesia as an office procedure and is indicated particularly in older patients. The hinged flap provides both the inner and outer layers of the alar rim. The donor site is closed primarily with no need to mobilize a large skin flap. The procedure leaves no conspicuous scars on the face. This method was found to be simple and safe, providing excellent tissue viability and yielding good color and texture match.     

Onlay cartilage graft of the alar lateral crus for cleft lip nasal deformities

The onlay cartilage grafting technique is described for treatment of unilateral or bilateral cleft lip nasal deformities. The alar cartilage is exposed through rim and intercartilagenous incisions. The cephalic half of the alar cartilage is excised, similar to the technique of traditional tip rhinoplasty. The harvested cartilage is applied to the intact caudal cartilage in layered fashion and secured with absorbable sutures. If necessary, successive layers may be added. These grafts provide a sturdy, yet delicate framework for a more normal appearing alar rim. We have performed this procedure on 16 patients, ages 10 to 41. Follow-up intervals range from 13 to 40 months, with a mean of 19 months. Results have been rated good-to-excellent by patients and surgeons. There has been no recurrence of the deformity. The only complication has been one nasal vestibule synechia.     

The residual unilateral cleft lip nasal deformity: a three-phase correction technique

The author presents a three-phase correction technique for the residual unilateral cleft lip nasal deformity. This procedure involves a sculpting excision of the alar rim, use of this alar rim as an interpositional flap in lengthening the columella, and augmentation of the nasal tip and perialar sulcus with a free ear conchal cartilage graft. The concept has been incorporated in the revisionary surgery program of 74 patients over a period of 5 years with a minimal follow-up of 2 years. The majority of the patients are operated on between the ages of 5 and 7 years based on the concept of a need for a "tidy appearance" by first grade.     

Anatomic reconstruction of the nasal tip cartilages in secondary and reconstructive rhinoplasty

Most techniques for secondary rhinoplasty assume that useful residual remnants of the tip cartilages remain, but frequently the alar cartilages are missing--unilaterally, bilaterally, completely, or incompletely--with loss of the lateral crura, middle crura, and parts of the medial crura. In such severe cases, excision of scar tissue and the residual alar remnants and their replacement with nonanatomic tip grafts have been recommended. Multiple solid, bruised, or crushed cartilage fragments are positioned in a closed pocket or solid shield-shaped grafts are fixed with sutures during an open rhinoplasty. These onlay filler grafts only increase tip projection and definition. Associated tip abnormalities (alar rim notching, columellar retraction, nostril distortion) are not addressed. Problems with graft visibility, an unnatural appearance, or malposition have been noted. Fortunately, techniques useful in reconstructive rhinoplasty can be applied to severe cosmetic secondary deformities. Anatomic cartilage replacements similar in shape, bulk, and position to normal alar cartilages can be fashioned from septal, ear, and rib cartilage, fixed to the residual medial crura and/or a columellar strut, and bent backward to restore the normal skeletal framework of the tip. During an open rhinoplasty, a fabricated and rigid framework is designed to replace the missing medial, middle, or lateral crus of one or both alar cartilages. The entire alar tripod is recreated. These anatomic alar cartilage reconstructive grafts create tip definition and projection, fill the lobule and restore the expected lateral convexity, position the columella and establish columellar length, secure and position the alar rim, and brace the external valve against collapse, support the vestibular lining, and restore a nostril shape. The anatomic form and function of the nasal tip is restored. This technique is recommended when alar cartilages are significantly destroyed or absent in secondary or reconstructive rhinoplasty and the alar remnants are insufficient for repair. Anatomically designed alar cartilage replacements allow an aesthetically structured skeleton to contour the overlying skin envelope. Problems with displacement are minimized by graft fixation. Graft visibility is used to the surgeon's advantage. A rigidly supported framework with a nasal shape can mold a covering forehead flap or the scarred tip skin of a secondary rhinoplasty and create a result that may approach normal. Anatomic alar cartilage reconstructions were used in eight reconstructive and eight secondary rhinoplasties in the last 5 years. Their use in the repair of postrhinoplasty deformities is emphasized.     

Asymmetric incision for open rhinoplasty in cleft lip nasal deformity.

One of the problems in the correction of the unilateral cleft lip nasal deformity is the alar web deformity on the mediosuperior side of the nostril. A number of methods for the correction of the alar web deformity have been introduced, but no single procedure has been identified as the standard. In this report, the incision line of the open rhinoplasty was modified and the alar web deformity was corrected by using an incision and closure. Open rhinoplasty with the asymmetric incision was performed on 18 patients with unilateral cleft lip nasal deformity. The incision line used in the normal side was the usual intranasal rim incision line and that used for the columella was the transcolumella incision line. For the cleft side, an intranasal rim incision line was plotted after the rim was lifted upward with forceps to achieve symmetry of the nasal tip. After removal of the forceps, the incision line of the cleft side was displaced outside the nostril. After such an incision, the alar cartilage mobilization and suspension were performed with or without the conchal cartilage graft. All patients used nasal retainers for 6 months after the procedures. So far, satisfactory results have been obtained with the modification of the incision line for open rhinoplasty. This method is unique in designing the incision line, and its procedure is rather simple. The postoperative follow-up period has been 12 to 26 months. A long-term follow-up is still needed, especially in growing children.     

Anatomy of the Caucasian alar groove

Anatomic studies performed on the noses of 15 cadavers examined the alar groove, alar lobule, and lower lateral crus areas both microscopically and on gross appearance to determine what effect these structures have on overall nasal appearance. In contrast to the findings of previous studies, the authors found the alar lobule to be an area in which dermis is interdigitated with muscle throughout and up to the alar rim. The anteroposterior lengths of the lower lateral crura were again seen to vary in length, presence or absence of accessory cartilages, and shape. Neither corrugation of the posterior elongation nor overlap of the accessory cartilages of the lower lateral cartilage had an effect on phenotype; sharp angles formed by the cartilage were blunted by the layer of fibrofatty muscular tissue between the cartilage and the skin. The alar groove, which lies at the junction of the lower lateral crus (medially) and the alar lobule (laterally), is defined not as much by a muscular attachment between the perichondrium of the lower lateral cartilage and the vestibular mucosa as by a bulging in the fatty layer on one side of the groove (within the cheek, lateral nasal wall, and nasal tip) and a relative paucity of fatty tissue on its other side (within the alar lobule).
