Congenital isolated absence of the nasal columella: reconstruction with an internal nasal vestibular skin flap and bilateral labial mucosa flaps

Congenital aplasia of the nasal columella is a very rare anomaly. The deformity is characterized by the isolated absence of the columella from the nasal tip to the root of the philtrum, including the medial crura of the alar cartilages; surrounding structures such as the septum, nose, and upper lip are normal. To the best of our knowledge, only four such cases have been described to date. The embryopathogenesis for this uncommon disease is presently unknown. Our report describes a 14-year-old girl with congenital agenesis of the columella as an isolated anomaly. Her family history was positive for the presence of the same congenital deformity, which also affected her older brother; there was, however, no consanguinity between the parents. The columella defect was reconstructed with an internal nasal vestibular skin flap and bilateral upper labial mucosa flaps. There are many techniques available to repair columella defects, including free grafts from the ear, local flaps from the forehead, face, upper lip, and nose, distant flaps such as tube pedicle flaps, and free flaps from the ear. Each of these techniques has advantages and disadvantages. Because of this, the treatment of columella defects should be individualized.     

Management of congenital bilateral cleft nose

A rare case of nasal clefting was presented to illustrate and emphasize the following points: The workup of nasal clefting should be complete to rule out associated deformities. Marked improvement may be noted with normal growth during the first few years of life. The surgical procedure employed a primary V-Y flap harvested from the central excess of nasal skin based on a very thin vascular area at the nasal columella. At this primary procedure, the flap was telescoped on itself to provide fullness in the nasal tip area. It was also split, and two transposition flaps were inset into the gap left behind by rotating the ala into normal position. The donor area of the V-Y flap provided easy access to the intercanthal area so that the excess skin on the bridge of the nose could be reduced. Two subsequent minor procedures were required for adjusting irregularities in the tip.     

A comparative study of the skin envelope of the unilateral cleft lip nose subsequent to rotation-advancement and triangular flap lip repairs

The secondary nasal skin envelope asymmetries were studied after unilateral cleft lip repair using the original (obsolete) rotation-advancement (Millard I) and the triangular flap techniques (Bardach's modification). Secondary correction of the nasal deformity was not performed in either group. Our findings indicated that in both groups, vertical asymmetries of the nasal skin envelope were similar. The alar dome on the cleft side was depressed, the columella was shorter on the cleft side, and there was hooding at the nostril apex. The principal difference between the two lip repairs was observed in the horizontal dimension of the nasal skin envelope. The position of the alar base was more normal following the Millard I repair, while the triangular flap repair left the alar base laterally displaced. When considered together with flattening of the cleft alar dome, a horizontal skin-envelope deficiency from middome to lateral alar crease was produced in the Millard I group. More lateral positioning of the alar base after the triangular flap technique minimized this horizontal skin deficiency. The triangular flap technique produced a secondary nasal deformity that looked worse but was easier to correct. The clinical implications of these findings are discussed.     

Nasal support and lining: the marriage of beauty and blood supply

Assured of a robust blood supply by its narrow pedicle centered on the septal branch of the superior labial artery, the pivoting septal flap provides nasal support from the radix to the most distal nasal tip and from the tip to the columella base--plus a large bonus of lining tissues for the nasal vault and vestibules. Lining flaps from such intranasal tissues are thin, vascular, and flexible. They allow the use of primary cartilage grafts and the establishment of a subsurface architecture in the shape of a nose. When visualized through a conforming forehead flap, the normal landmarks and highlights are restored. In cases of total nasal amputation, a pivoting septal flap permits the fabrication of dorsal nasal support weeks before lining and cover flaps are assembled.     

Primary repair of the bilateral cleft lip nose: a 15-year review and a new treatment plan

For 15 years a forked flap has been used for columella reconstruction in primary repair of the bilateral cleft lip nose. With the adolescent growth spurt, three unfavorable features have become apparent: (1) the columella may grow too long and the nostrils too large, (2) often the nasal tip remains broad, and (3) there is a drift of the columellar base and the lip-columellar angle is transgressed by scar. This procedure has therefore been discontinued. A new treatment plan is presented in which the columella is reconstructed from tissues in the splayed-out nasal tip.     

Designs for correction and camouflage of bilateral clefts of the lip and palate

The bilateral cleft anomaly is difficult to correct and camouflage because of the double lack of many important landmarks and the shortness of skin in the midvertical plane. A possible solution in patients who have some columella or in those of races not needing a long columella is the strap flap advancement of the nostril sills and alar bases. In all other cases, the forked flap is the method of choice for adequate correction and camouflage of the bilateral cleft lip-nose deformity.     

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.     

Measurement precision and reliability in craniofacial anthropometry: implications and suggestions for clinical applications.

Craniofacial anthropometry has become an important tool used by both clinical geneticists and reconstructive surgeons. Yet little attention has been paid to the potentially serious problem of measurement error. This paper examines intra-observer measurement error and precision (also called repeatability or reliability) for 52 commonly used anthropometric variables of the head and face. Two factors proved critical to reliability: magnitude of the measurement in question and the degree to which its constituant landmarks could be readily identified. Thus, all of the measurement variables with means above 10 cm proved to have good or excellent reliability. In contrast measurement variables with means below 10 cm were more likely to have poor reliability. This trend was especially evident in variables with means of 6 cm or less where 18 of the 20 variables in this range had poor reliability. The least reliable variables were those like philtrum breadth, columella breadth, and nasal root breadth that combine small magnitude with difficult to define landmarks. While these results suggest that it may be prudent to avoid using craniofacial variables with small dimensions this may be neither practical nor desirable. In such cases repeat measurements may be the best means for optimizing reliability.     

Reconstruction of proximal nasal defects with island composite nasal flaps

There are few local nasal flap options for repair of proximal nasal defects. Absence of suitable donor sites and the large dimensions of the defects limit the use of local nasal flaps in this region. Regional paranasal flaps may not be suitable in these cases because of color, texture, and donor-site scars. The composite procerus muscle and nasal skin flap, which is vascularized by the dorsal nasal branch of the angular artery, can be a useful treatment modality for proximal nasal reconstruction. Seven patients were successfully treated using the composite nasal flaps. The maximal size of the defects was 2.4 cm. In one case, the composite nasal flap was readvanced to close a new defect resulting from reexcision. The composite nasal flap has several advantages in reconstruction of proximal nasal defects. Reconstruction is performed with the same tissue and the donor defect is closed primarily. The composite nasal flap can be moved in multiple directions and has great mobility to reach every point of the proximal part of the nose with axial blood supply. Furthermore, it can be easily readvanced without additional morbidity in case of reexcision.     

Caudal nasal deviation

Caudal nasal deviation, manifested by a "crooked tip," asymmetric nostrils, and a deviated columella, is one of the most challenging deformities encountered in rhinoplasty. This entity is often ignored by rhinoplasty surgeons, on the basis of the assumption that correction of other segments of the deviated nose will improve the caudal nose. Failure to correct this imperfection (or, occasionally, deformity) invariably produces suboptimal results. The nasal structures involved in caudal nasal deviation, namely, the septum, the lower lateral cartilages, and the anterior nasal spine, must be evaluated for identification of the anatomical blocks that have a causative role in caudal nasal deviation. The specific structures with abnormalities related to this deformity are discussed, as are techniques for the correction of the deformities. These techniques significantly augment the surgeon's repertoire of methods for addressing the subtleties of caudal nasal deviation correction and achieving predictable results.     

Unilateral cleft lip repair

The marking of the medial lip segment of the Millard rotation advancement procedure for repair of the unilateral cleft lip has been altered in the uppermost portion by utilizing tissue from the columellar base. Once adequate length has been obtained, cutback is utilized at approximately 90 degrees. With adequate full-thickness release of this medial lip segment and subsequent rotation into the proper position, the C flap is advanced into the donor defect of the columellar base and is also used to lengthen the shortened columella on the cleft side. This results in placement of a scar that will closely simulate the "mirror image" of the noninvolved philtral column. Fifty-seven patients with unilateral cleft lip have been repaired utilizing this technique during the past 14 years. Several of these children have required secondary surgeries because of mucosal irregularities or residual nasal deformities, but none has required additional surgery because of inadequate rotation of the medial lip segment or for correction of any donor-site defect at the base of the columella.     

A new twist to the nasolabial flap for reconstruction of lateral alar defects

The nasolabial flap remains the favored technique for alar and lateral nasal reconstruction. Results with currently popular techniques tend to be inartistic and aesthetically disappointing. Improved results can be achieved, however, by a technique using a medially based nasolabial turnover flap for lining with a distal extension providing the cover. Reconstruction of the ala begins by designing a nasolabial flap with its base as close as possible to the site of the proposed ala. The flap is incised to the required margins, carrying 2 to 3 mm of underlying fat; then, hinged on its base, the flap is flipped over medially like the page of a book. As the proximal flap is sutured to the lining side of the defect, the distal flap gracefully twists 90 degrees and is then folded on itself to form the external surface of the ala. The donor site is closed primarily. With this procedure, a natural-appearing and appropriately positioned ala may be reconstructed in one step, although a second procedure may be helpful to sculpture the margin or precisely position the alar base.     

A 10-year experience in nasal reconstruction with the three-stage forehead flap

Because of its ideal color and texture, forehead skin is acknowledged as the best donor site with which to resurface the nose. However, all forehead flaps, regardless of their vascular pedicles, are thicker than normal nasal skin. Stiff and flat, they do not easily mold from a two-dimensional to a three-dimensional shape. Traditionally, the forehead is transferred in two stages. At the first stage, frontalis muscle and subcutaneous tissue are excised distally and the partially thinned flap is inset into the recipient site. At a second stage, 3 weeks later, the pedicle is divided. However, such soft-tissue "thinning" is limited, incomplete, and piecemeal. Flap necrosis and contour irregularities are especially common in smokers and in major nasal reconstructions. To overcome these problems, the technique of forehead flap transfer was modified. An extra operation was added between transfer and division.At the first stage, a full-thickness forehead flap is elevated with all its layers and is transposed without thinning except for the columellar inset. Primary cartilage grafts are placed if vascularized intranasal lining is present or restored. Importantly, at the first stage, skin grafts or a folded forehead flap can be used effectively for lining. A full-thickness skin graft will reliably survive when placed on a highly vascular bed. A full-thickness forehead flap can be folded to replace missing cover skin, with a distal extension, in continuity, to supply lining. At the second stage, 3 weeks later during an intermediate operation, the full-thickness forehead flap, now healed to its recipient bed, is physiologically delayed. Forehead skin with 3 to 4 mm of subcutaneous fat (nasal skin thickness) is elevated in the unscarred subcutaneous plane over the entire nasal inset, except for the columella. Skin grafts or folded flaps integrate into adjacent normal lining and can be completely separated from the overlying cover from which they were initially vascularized. If used, a folded forehead flap is incised free along the rim, completely separating the proximal cover flap from the distal lining extension. The underlying subcutaneous tissue, frontalis muscle, and any previously positioned cartilage grafts are now widely exposed, and excess soft tissue can be excised to carve an ideal subunit, rigid subsurface architecture. Previous primary cartilage grafts can be repositioned, sculpted, or augmented, if required. Delayed primary cartilage grafts can be placed to support lining created from a skin graft or a folded flap. The forehead cover skin (thin, supple, and conforming) is then replaced on the underlying rigid, recontoured, three-dimensional recipient bed. The pedicle is not transected. At a third stage, 3 weeks later (6 weeks after the initial transfer), the pedicle is divided.Over 10 years in 90 nasal reconstructions for partial and full-thickness defects, the three-stage forehead flap technique with an intermediate operation was used with primary and delayed primary grafts, and with intranasal lining flaps (n = 15), skin grafts (n = 11), folded forehead flaps (n = 3), turnover flaps (n = 5), prefabricated flaps (n = 4), and free flaps for lining (n = 2). Necrosis of the forehead flap did not occur. Late revisions were not required or were minor in partial defects. In full-thickness defects, a major revision and more than two minor revisions were performed in less than 5 percent of patients. Overall, the aesthetic results approached normal.The planned three-stage forehead flap technique of nasal repair with an intermediate operation (1) transfers subtle, conforming forehead skin of ideal thinness for cover, with little risk of necrosis; (2) uses primary and delayed primary grafts and permits modification of initial cartilage grafts to correct failures of design, malposition, or scar contraction before flap division; (3) creates an ideal, rigid subsurface framework of hard and soft tissue that is reflected through overlying skin and blends well into adjacent recipient tissues; (4) expands the application of lining techniques to include the use of skin grafts for lining at the first stage, or as a "salvage procedure" during the second stage, and also permits the aesthetic use of folded forehead flaps for lining; (5) ensures maximal blood supply and vascular safety to all nasal layers; (6) provides the surgeon with options to salvage reconstructive catastrophes; (7) improves the aesthetic result while decreasing the number and difficulty of revision operations and overall time for repair; and (8) emphasizes the interdependence of anatomy (cover, lining, and support) and provides insight into the nature of wound injury and repair in nasal reconstruction.     

The median forehead flap revisited: the blood supply

In 6 fresh cadavers, an injection study of the facial vessels with disulfine blue dye and Microfil demonstrated visualization of large-caliber vessels of the median forehead skin even when the supraorbital and supratrochlear vessels were interrupted. The results of the study would suggest that the median forehead flap can be elevated without incorporating the supratrochlear vessels, but the flap design should be reserved for those clinical situations where the pedicle must be extensively mobilized, e.g., reconstruction of the nasal tip and columella and the presence of a low-lying frontal hairline.     

The "iatrogenic-hanging columella": preserving columellar contour after tip retroprojection

This article discusses a method for treating the ultraprojecting tip by the resection of columellar skin in open rhinoplasty. Lack of postoperative contraction of columellar skin and soft tissue may result in an "iatrogenic-hanging columella." Columellar skin resection frequently produces its own deformities because of a discrepancy in the width of the columellar base side and the infralobular flap side. The ultraprojecting tip was present in 56 of 660 consecutive rhinoplasty patients (8 percent) over 8 years (1991 to 1998). Of these 56 patients, 48 underwent partial resection of the infralobular skin flap. Of these 48 patients, eight (17 percent) required secondary skin revision of the columellar resection area. The technique was then modified since 1998. Over 2 years, 13 of 129 consecutive rhinoplasty patients (10 percent) were judged to have an ultraprojecting tip. Of these, eight patients were treated with a modification in the technique by resecting skin on the posterior columellar base. No resection areas were revised in the second series. Of the 789 patients in both series, 647 (82 percent) underwent primary rhinoplasties, 126 (16 percent) had secondary rhinoplasties, and 16 (2 percent) had tertiary rhinoplasties. The treatment of excess columella skin adds a subtle aesthetic improvement to the postoperative nasal contour. By resecting skin on the posterior columellar base or the posterior columellar base and, rarely, the anterior flap, an iatrogenic-hanging columella can be avoided.     

The Turkish delight: a pliable graft for rhinoplasty

In nose surgery, carved or crushed cartilage used as a graft has some disadvantages, chiefly that it may be perceptible through the nasal skin after tissue resolution is complete. To overcome these problems and to obtain a smoother surface, the authors initiated the use of Surgicel-wrapped diced cartilage. This innovative technique has been used by the authors on 2365 patients over the past 10 years: in 165 patients with traumatic nasal deformity, in 350 patients with postrhinoplasty deformity, and in 1850 patients during primary rhinoplasty. The highlights of the surgical procedure include harvested cartilage (septal, alar, conchal, and sometimes costal) cut in pieces of 0.5 to 1 mm using a no. 11 blade. The fine-textured cartilage mass is then wrapped in one layer of Surgicel and moistened with an antibiotic (rifamycin). The graft is then molded into a cylindrical form and inserted under the dorsal nasal skin. In the lateral wall and tip of the nose, some overcorrection is performed depending on the type of deformity. When the mucosal stitching is complete, this graft can be externally molded, like plasticine, under the dorsal skin. In cases of mild-to-moderate nasal depression, septal and conchal cartilages are used in the same manner to augment the nasal dorsum with consistently effective and durable results. In cases with more severe defects of the nose, costal cartilage is necessary to correct both the length of the nose and the projection of the columella. In patients with recurrent deviation of the nasal bridge, this technique provided a simple solution to the problem. After overexcision of the dorsal part of deviated septal cartilage and insertion of Surgicel-wrapped diced cartilage, a straight nose was obtained in all patients with no recurrence (follow-up of 1 to 10 years). The technique also proved to be highly effective in primary rhinoplasties to camouflage bone irregularities after hump removal in patients with thin nasal skin and/or in cases when excessive hump removal was performed. As a complication, in six patients early postoperative swelling was more than usual. In 16 patients, overcorrection was persistent owing to fibrosis, and in 11 patients resorption was excessive beyond the expected amount. A histologic evaluation was possible in 16 patients, 3, 6, and 12 months postoperatively, by removing thin slices of excess cartilage from the dorsum of the nose during touch-up surgery. This graft showed a mosaic-type alignment of graft cartilage with fibrous tissue connection among the fragments. In conclusion, this type of graft is very easy to apply, because a plasticine-like material is obtained that can be molded with the fingers, giving a smooth surface with desirable form and long-lasting results in all cases. The favorable results obtained by this technique have led the authors to use Surgicel-wrapped diced cartilage routinely in all types of rhinoplasty.     

History of total nasal reconstruction with particular emphasis on the folded forehead flap technique

The history of plastic surgery is identified throughout the centuries with the history of rhinoplasty. The Indian Koomas first and later the Italian surgeons found valid solutions to the problems caused by partial loss of the nasal pyramid. However, the idea of rebuilding, with a single forehead flap, the tip and columella and providing at the same time a lining of skin for the newly formed nose goes back to the middle of the nineteenth century. The Italian Natale Petrali (1842) and the Germans Johann Friedrich Dieffenbach (1845) and Ernst Blasius (1848) contend for precedence in carrying out this important procedure still used today, which, barring postoperative contracture, represented a great advance in successful total rhinoplasty.

Facial artery in the upper lip and nose: anatomy and a clinical application

Twenty-five facial arteries were examined radiographically in 19 fresh cadavers that had been injected systemically with a lead oxide-gelatin mixture. Major branches of the facial artery in the upper lip and nose were investigated, and the anatomical variations were classified into three types on the basis of the anatomy of the lateral nasal artery, which was determined as an artery running toward the alar base. In 22 cases (88 percent), the facial artery bifurcated into the lateral nasal artery and superior labial artery at the angle of the mouth. In two cases (8 percent), the facial artery became an angular artery after branching off into the superior labial artery and the lateral nasal artery sequentially. In one case (4 percent), the facial artery became an angular artery after branching off into the superior labial artery, and the lateral nasal artery then branched off from the superior labial artery. Branches from the lateral nasal and superior labial arteries were observed stereographically. Vascular anastomoses between those branches were created in the upper lip, columella base, and nasal tip, and an intimate vascular network was formed. With a vascular network in the mucosa of the upper lip, a bilobed upper-lip flap was created for a clinical case with a full-thickness defect of the ala.     

A new technique in nasal-tip reduction surgery.

This article presents a technique for the reduction of the overprojected nasal tip with a proportional reduction of the nostril-margin circumference. To achieve these reductions, a modified open rhinoplasty technique is used, which is unique in that it involves the total transection of the columella through the medial crura of the alar cartilage. The alar cartilage is raised with the flap.The technique was first developed and introduced by the senior author (R.A.S.) 25 years ago and has since been refined through the execution of several thousand rhinoplasties. The results continue to be consistent and pleasing from both the patients' and the surgeon's points of view.
