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.     

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.     

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.     

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.     

Resorbable internal splint: an adjunct to primary correction of unilateral cleft lip-nasal deformity

There is usually some relapse in position of the alar cartilage after primary repair of unilateral cleft lip. Therefore, preoperative or postoperative external splinting has been recommended to supplement either closed or open suspension of the alar cartilage. The authors present a method using a resorbable internal nostril splint to shield the positioned alar cartilage from deformational forces caused by scar, and thus avoiding the problems associated with external splinting. An internal nasal splint was placed in 15 infants during repair of unilateral complete cleft lip and nasal deformity. The nasal morphology was compared with that of 15 control patients who had the same nasolabial procedure without internal splinting. Average follow-up time was 20.4 months (range, 4 to 30 months). Photogrammetric analysis showed that asymmetry of the alar contours averaged 8.6 percent in the splinted patients, as compared with 23 percent for controls (p <0.01). Thus, alar asymmetry was decreased two-thirds in the splinted group. An internal resorbable nasal splint is an adjunct to open alar suspension in primary repair of the unilateral cleft lip nasal deformity. An internal nasal splint protects the corrected alar cartilage longer than an external splint and eliminates drawbacks, such as necrosis, cutaneous depression of the nostril sill, and patient noncompliance. This strategy of temporary internal support of healing cartilage has other applications.     

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.     

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.     

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.     

Primary correction of the unilateral cleft nasal deformity

An 18-year experience with the management of the unilateral cleft nasal deformity in 1200 patients is presented. A primary cleft nasal correction was performed at the time of lip repair in infancy; a secondary rhinoplasty was done in adolescence after nasal growth was complete. The technical details of the authors' primary cleft nasal correction are described. Exposure was obtained through the incisions of the rotation-advancement design. The cartilaginous framework was widely undermined from the skin envelope. The nasal lining was released from the piriform aperture, and a new maxillary platform was created on the cleft side by rotating a "muscular roll" underneath the cleft nasal ala. The alar web was then managed by using a mattress suture running from the web cartilage to the facial musculature. In 60 percent of cases, these maneuvers were sufficient to produce symmetrical dome projection and nostril symmetry. In the other 40 percent, characterized by more severe hypoplasia of the cleft lower lateral cartilage, an inverted U infracartilaginous incision and an alar dome supporting suture (Tajima) to the contralateral upper cartilage were used. Residual dorsal hooding of the lower lateral cartilage was most effectively managed with this suture. This primary approach to the cleft nasal deformity permits more balanced growth and development of the ala and domal complex. Some of the psychological trauma of the early school years may be avoided. Also, because of the early repositioning of the cleft nasal cartilages, the deformity addressed at the time of the adult rhinoplasty is less severe and more amenable to an optimal final result.     

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).     

Primary repair of the unilateral cleft lip nose in the Oriental: a 20-year follow-up

The unilateral cleft lip nasal deformity is corrected as a primary procedure with the lip repair. The abnormal attachment of the alar base is first released by an incision along the superior buccal sulcus and piriform margin. There is no intercartilaginous incision. Basically, we use the Brown-McDowell technique with the addition of an alar rim incision. Undermining of the ala between the two incisions is carefully and adequately done, splitting it into two layers. The first is a skin and the second, a chondrocutaneous (vestibular skin) layer, which is handled as a single unit, thus enhancing its vascularity. This second layer is a bipedicle flap with a broad medial pedicle and a narrow lateral pedicle at the alar base. When the alar base is rolled into its normal position, the chondrocutaneous unit hinging on its two pedicles counterrotates, correcting the subluxation of the ala, a major component of the cleft lip nasal deformity. We depend on the normal position of the alar base, the postoperative scar tissue, and the inherently thick nostril wall in the Oriental to keep the alar dome up. No transfixion sutures are used. Ten consecutive patients are shown 20 years after surgery. All had one operation only. None showed any disturbance of nasal growth.     

Cleft lip nose correction with onlay calvarial bone graft and suture suspension in Oriental patients

To correct the secondary cleft lip nose deformity in Oriental patients, many alar cartilage mobilization and suspension techniques have been developed. However, these techniques have critical limitations. One of the limitations is the suspension vector, and another is suspension power. The suspension vector is from inferior to superior and from the deformed alar cartilage to the normal alar cartilage. Thus, the vector is not suitable for normal nasal tip projection. The suspension power is not satisfactory because Oriental people have underdeveloped, thin alar cartilages and thick skin. So, the suspended, deformed alar cartilage may relapse and pull the normal alar cartilage to the deformed side. To overcome these limitations, the authors use the cantilever calvarial bone graft for tip projection; it also serves as a strong, rigid framework for cartilage and soft-tissue suspension. Using these techniques, the authors can create normal nasal tip projection and a normal looking nasal aperture.     

Secondary correction of the unilateral cleft lip nose using a conchal composite graft

The secondary deformity of the unilateral cleft lip nose has many components. One is the dorsal dislocation of the lateral crus of the alar cartilage. We used a conchal composite graft positioned between the piriform aperture and the lateral crus and the upper lateral cartilage to correct this dislocation in nine patients. We believe that this graft is effective because it elevates the lateral crus of the alar cartilage off the depressed piriform aperture. This technique is very simple to perform, and it is easy to achieve nasal symmetry. Our results have been quite satisfactory, with no recurrence of dorsal dislocation. The donor site was covered by a subcutaneous pedicled flap from the cephaloauricular sulcus, leaving an inconspicuous deformity.     

A problem-oriented and segmental open approach to alar cartilage losses and alar length discrepancies

Alar cartilage losses and alar length discrepancies present problems in nasal tip support, contour, and symmetry. The true extent of the cartilage defect is often not apparent until the time of surgery. This article examines a problem-oriented and segmental open approach to such deformities. It is based on the size of the defect, its location within the dome and lateral crus, and the presence or absence of alar collapse. The defects are classified as major when there is a total or near total loss of the lateral crus, moderate when more than 5 mm is involved, and minor when less than 5 mm is affected. In major defects, a segmental reconstruction of the nasal tip cartilages is undertaken. It consists of a septal graft for columellar support and a conchal shield graft and umbrella graft for nasal tip contour. The whole length of the lateral crus is not reconstructed unless alar collapse is present. In moderate cartilage defects, usually seen laterally in secondary rhinoplasties, the remaining central dome segments are remodeled with shaping sutures. Moderate cartilage length discrepancies, as seen in unilateral cleft lip noses, are equalized through reversed alar rotations. The short crus is rotated laterally, taking length from the medial crus, and the long crus is rotated medially, with the excess advanced into the medial crural footplate. Additional shortening of the long crus can be achieved through cartilage division and advancement. The balanced alar units are then raised with tip projection-vector sutures, and onlay grafts are added if required. In minor cartilage losses, symmetry is usually obtained by shortening the opposite uninjured crus. A total of 33 patients are examined in this review. The average follow-up is 14 months. An improvement in nasal tip shape and support was achieved in all patients.     

Alar rim raising.

The relationship of the alar rim to columella visibility and nostril proportion is crucial to a good aesthetic result. The alar rim has been a neglected part of the nose in primary and secondary rhinoplasty procedures for want of a natural contouring operation. Results of directly excising the alar rim and its indications are presented with adequate follow-up. Indications for the procedure include (1) recontouring of the cleft lip nose with anterior webbing, (2) equalizing asymmetrical nostrils, (3) enlarging small nostrils, (4) correcting a hanging (sigmoid) ala, and (5) converting round to oval nostrils.     

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.     

The principle of rotation advancement for repair of unilateral complete cleft lip and nasal deformity: technical variations and analysis of results.

This is an assessment of one surgeon's 15-year experience (1981-1995) using the Millard rotation-advancement principle for repair of unilateral complete cleft lip and nasal deformity. All infants underwent a prior labio-nasal adhesion. Since 1991, dentofacial orthopedics with a pin-retained (Latham) appliance was used for infants with a cleft of the lip and palate. Technical variations are described, including modifications in sequence of closure. A high rotation and releasing incision in the columella lengthens the medial labial element and produces a symmetric prolabium with minimal transgression of the upper philtral column by the advancement flap. Orbicularis oris muscle is everted, from caudad to cephalad, to form the philtral ridge. A minor variation of unilimb Z-plasty is used to level the cleft side of Cupid's bow handle, and cutaneous closure proceeds superiorly from this junction. The dislocated alar cartilage is visualized though a nostril rim incision and suspended to the ipsilateral upper lateral cartilage. Symmetry of the alar base is addressed in three dimensions, including maneuvers to position the deviated anterior-caudal septum, configure the sill, and efface the lateral vestibular web. Secondary procedures were analyzed in 105 consecutive patients, both revised (n = 30) and unrevised (n = .75). The possible need for revision in the latter group was determined by panel assessment of six indicators of nasolabial asymmetry, documented by frontal and submental photographs. In the entire study period, a total of 80 percent of children required or will need nasal revision, and a total of 42 percent required or will require labial revision. In the last 5 years, as compared with the earlier decade, there was a significantly diminished incidence of patients requiring labial revision (54 percent to 21 percent) and alar suspension (63 percent to 32 percent). These improvements are attributable to technical refinements and experience, although dentofacial orthopedics may also have played a role.     

Use of cartilaginous autografts in nasal surgery: 8 years of experience

Although the cartilaginous autografts are one of the tissues more utilized in nasal surgery, a comparative study does not exist to determine which are better options and their precise indications. It is for this reason that a histopathologic analysis was carried out comparing the characteristics and properties of the four principal cartilages that are utilized in aesthetic functional surgery of the nose. Considering these particularities, the precise indications for the employment of the different cartilage as nasal autografts were determined. Of 1120 aesthetic functional rhinoplasties during a period of 8 years, 930 (83 percent) required cartilaginous autografts, 86 percent were primary, 11 percent were secondary, and 3 percent had two or more surgeries. Eighty-three percent of the grafts used were from nasal septum, 12 percent from the auricle, 3 percent from alar cartilages, and 2 percent from the rib. The anatomic sites in which they were employed consisted of the following: 64 percent between the medial crura, 28 percent as in Sheen's graft, 19 percent in the nasal dorsum, 8 percent as spreader grafts, 8 percent as in Peck's graft, and 3 percent in the rim to improve alar collapse. We followed at all times the previous indications for obtaining and placing the nasal autografts. Eighty-four percent of the patients were totally satisfied and only 8 percent required a second surgical procedure to achieve the results desired. Based on this study, it is recommended to utilize the cartilaginous autografts in nasal surgery considering three parameters: the physical and histologic characteristics of each cartilage, the anatomic site in which they are to be placed, and the effect desired with their application.     

Secondary rhinoplasty using flying-bird and vestibular tornado incisions for unilateral cleft lip patients

To correct the nasal deformity in cleft lip patients, a new procedure of open rhinoplasty using a "flying-bird" incision in the nostril tip with a vestibule "tornado"-shaped incision in the cleft side is presented. The newly designed vestibular incision produces effective vestibular advancement with the freed lower lateral cartilage. The flying-bird incision makes it possible to produce a suitable nostril tip appearance with symmetrical external nostril vestibules. If the vestibular defect after flap advancement is wide, a full-thickness skin graft is used to give priority for making a good external nostril shape. This procedure is useful for most cleft lip noses, particularly in cases of moderate to severe deformity.     

The use of nasal splints in the primary management of unilateral cleft nasal deformity

Primary surgical correction of the cleft lip nasal deformity is routinely performed at the Craniofacial Center at Chang Gung Memorial Hospital. Over time, however, there is a tendency for the lower lateral cartilage to retain its memory and, subsequently, recreate the preoperative nasal deformity. Therefore, it is current practice to use a nostril retainer for a period of at least 6 months to maintain the corrected position of the nose. The aim of this study was to qualitatively assess the benefit of postoperative nasal splinting in the primary management of unilateral cleft nasal deformity. Data from two groups of 30 patients with complete unilateral cleft lips each were retrospectively collected and analyzed. The first group served as a control (no nasal splints), and the second group used the nasal retainer compliantly for at least 6 months postoperatively. All patients had their primary lip repair at 3 months of age. A photographic evaluation of the results when the patients were between 5 and 8 years of age was conducted. The parameters used to assess the nasal outcome were nostril symmetry, alar cartilage slump, alar base level, and columella tilt. The first scores were based on residual nasal deformity, and the second set were based on overall appearance. It was found that the mean scores of residual nasal deformity for all four parameters in patients who used the nasal stent were statistically better than the scores of patients who did not (p values ranged from 0.0001 to 0.005). The overall appearance scores for the four parameters in the patients who used the nasal stent after surgery were also statistically better than the scores for those who did not (p values ranged from 0.0001 to 0.01). The results show that postoperative nasal splinting in the primary management of the unilateral cleft nasal deformity serves to preserve and maintain the corrected position of the nose after primary lip and nasal correction, resulting in a significantly improved aesthetic result. Therefore, it is recommended that all patients undergoing primary correction of complete unilateral cleft deformity use the nasal retainer postoperatively for a period of at least 6 months.
