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.     

Various uses of the septum in rhinoplasty

The nasal septum can be used with impunity to assist in cosmetic and reconstructive rhinoplasty if an L-shaped bridge with anterior prow is preserved or constructed to maintain normal support to the nose. The septum can serve, of course, as a reservoir of cartilage grafts. Under special conditions, it can spare mucosal and chondromucosal or even osteochondromucosal flaps to aid in the supply of lining and support in reconstructions. The L-shaped septal chondromucosal flap has been found of value in total distal reconstructions and is now offered as a possible adjunct in the correction of certain intact but congenitally flat and/or short noses.     

Nasal reconstruction with a forehead flap in children younger than 10 years of age

Nasal reconstruction has been analyzed extensively in adults but not in children. The purpose of this article is to review the authors' experience with the forehead flap for nasal reconstruction in 10 children under the age of 10 during a 10-year period. Outcomes were assessed by an objective grading system for cosmetic surgical results. Subjective criteria were also applied by an assistant surgeon and by the patients' relatives. Appropriate results were obtained by the following principles: (1) A modified approach that considers three subunits consisting of the dorsum, tip, and ala was used; (2) a forehead flap is the best option for an entire subunit or a full-thickness defect repair; (3) the forehead flap design should be paramedian, oblique, and opposite to the major defect to avoid the hairline and allow better caudal advancement; (4) ear or costal cartilages are good options for structural support (the septum is a nasal growth center that should not be touched); (5) infundibular undermining of vestibular mucosa, turnover flaps, and skin grafts are good options for internal lining; (6) reconstruction is a three-stage procedure (an intermediate operation is added to thin the flap and perform secondary revisions for lining and support); (7) reconstruction should be completed before the child is school aged, to achieve good aesthetic results immediately and avoid psychosocial repercussions; and (8) the reconstructed nose, with skin, lining, and support, will grow with the child (no final surgery should be planned at the age of 18, other than revisions of late complications).     

Oronasal fistula repair with three layers

We present an innovative method for closure of oronasal fistulas involving a three-layer repair, consisting of septal mucosa flap, bone or cartilage graft, and palatal mucosa flap. The septal mucosa flap closes the nasal side of the defect. This is an inferiorly based flap along the nasal floor and consists of septal mucosa from the side opposite the oronasal fistula. A slit is created in the remaining layers of the nasal septum, allowing the flap to be delivered into the defect. When the septal flap is folded down in this fashion, it exposes nasal septal bone and cartilage. The bone and cartilage are harvested and are used to create the middle layer of the three-layer fistula repair. The oral layer of the repair is provided by a palatal mucosa transposition flap. This method allows the bone/cartilage graft to be sandwiched between two vascular layers. We have successfully used the three-layer repair on three patients. All of the oronasal defects were 2 cm in size. All patients are at least 1 year after repair with 100 percent closure; thus, no oronasal leakage. The flaps both septal and palatal resulted in no morbidity once healed. Specifically, the surgically created slit in the nasal septum is well mucosalized and barely discernible. Also, no nasal obstruction occurs from the septal flap on the floor of the nose. We perform the procedure on an outpatient basis. The three-layer repair can be used in adult patients with oronasal fistulas of the middle and posterior hard palate up to 3 cm in size. This technique is not recommended for children.     

Reconstruction of large nasal defects with a combination of local flaps based on the aesthetic subunit principle

Herein is described a technique that uses a combination of local flaps to reconstruct large defects involving the nasal dorsum and cheek. The flaps used are a transposition flap elevated from the area adjoining the defect and bilateral cheek advancement flaps. This technique leaves all suture wounds at borders of the aesthetic subunits that have been described previously. Color and texture matches were good and symmetrical. The transposition flap can be modified according to whether the defect includes the nasal tip. After raising the cheek advancement flap, it is also possible to use a dog-ear on the nasolabial region for any alar defects. Nine patients were treated using this procedure. The technique is very reliable (no complications such as congestion and skin necrosis in our series) and is easy to perform. One patient had palpebral ectropion after the operation and underwent secondary repair. In this series, defects measuring 45 x 30 mm in maximum diameter and including the nasal dorsum, nasal tip, ala, and cheek were treated.     

Complex nasal reconstruction

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Describe the goals of nasal reconstruction as they apply to extensive, complex defects that may also involve the adjacent lip or cheeks. 2. Understand the advantages and disadvantages of different options for reconstruction of lining, skeletal support, and skin cover. 3. Discuss current advances in complex nasal reconstruction, including microvascular reconstruction of lining and the three-stage forehead flap. 4. Understand the concepts of laminated and prelaminated flaps and their application in complex nasal defects. SUMMARY: In this article, the authors review methods of reconstructing complex, multilayered nasal defects that may involve surrounding central facial structures. Different means of lining, skeletal support, and skin cover reconstruction are discussed. Emphasis is placed on newer, state-of-the art techniques and reinforcing basic principles.     

Reconstruction of the nose damaged by cocaine

Nasal snorting of cocaine crystals causes destruction of the septal and nasal mucosa, which eventually provides exposure of the septal cartilage and nasal bones. This exposure eventually leads to septal chrondritis and nasal bone osteomyelitis. As this process continues, the severe loss of cartilage and bone allows gradual to total collapse of the nose. Correction of this deformity is best achieved by supplying new lining; this is possible by turning nasolabial flaps into the nasal vestibule to replace the lost and released lining. Once this has been accomplished, costal cartilage grafts can be inserted along the bridge and alae to maintain the structural integrity of the reconstruction.     

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.     

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.     

A radical method of correcting the nasal deformity in adult patients with repaired unilateral lip clefts

A method of rhinoseptoplasty is described, which combines principles of several well-known procedures, with innovations introduced by the author, for the purpose of eliminating the causes of complex distortions of the lip, maxilla, and nose in unilateral clefts. This method aims at creating a secure support for the atrophic alar cartilage with a pedicled cartilage flap taken from the normal alar cartilage. Elevation of the dome and elongation of the columella on the cleft side are achieved by interdigitating mucocutaneous flaps. To improve symmetry and relieve nasal obstruction, the ala on the normal side is also corrected, as well as the deflected septal cartilage and the anterosuperior margin of the vomer.     

A modified Goldman nasal tip procedure for the drooping nasal tip

A modification of Irving Goldman's nasal tip procedure that borrows from the lateral crus to augment the height of the medial crus is described. Goldman's procedure has been modified by not including the vestibular skin with the segment of the lateral crus that is rolled medially to increase nasal tip projection, by adding a nasal septal cartilage strut between the medial crura for support when the medial crura are weak, and by maintaining a small separation caudally of the repositioned lateral crura at the new nasal dome to simulate a double nasal dome. This modified Goldman nasal tip procedure allows the surgeon to reshape the lower lateral nasal cartilage to increase nasal tip projection as an alternative to the use of a shield-type nasal tip graft, and at the same time it narrows the nasal tip with minimal resection of the lateral crus of the lower lateral nasal cartilage.     

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.     

Nasal reconstruction based on aesthetic subunits in Orientals

Reconstruction based on the aesthetic subunit principle has yielded good aesthetic outcomes in patients with moderate to severe nasal defects caused by trauma or tumor resection. However, the topographic subunits previously proposed are often unsuitable for Orientals. Compared with the nose in white patients, the nose in Orientals is low, lacks nasal muscle, and has a flat glabella; the structural features of the underlying cartilage and bone are not distinctly reflected in outward appearance. The authors devised aesthetic subunits suitable for Orientals, and they used these units to reconstruct various parts of the nose. The major difference between these units and those presented previously is the lack of soft triangles and the addition of the glabella as an independent unit. The authors divided the nose into the following five topographic units: the glabella, the nasal dorsum, the nasal tip, and the two alae. The border of the nasal dorsum unit was extended to above the maxillonasal suture. The basic reconstruction techniques use a V-Y advancement flap from the forehead to reconstruct the glabella, an island flap from the forehead to reconstruct the nasal dorsum and nasal tip, a nasolabial flap to reconstruct an ala, and a malar flap to reconstruct the cheek. A combination of flaps was used when the defect involved more than one unit. This concept was used for nasal reconstruction in 24 patients. In one patient undergoing reconstruction of the nasal dorsum and in one undergoing reconstruction of the nasal tip, the texture of the forearm flap did not match well, which resulted in a slightly unsatisfactory aesthetic outcome. In one patient in whom the glabella, nasal dorsum, and part of the cheek were reconstructed simultaneously, a web was formed at the medial ocular angle, and a secondary operation was subsequently performed using Z-plasty. In one patient undergoing reconstruction with a forehead flap, defatting was required to reduce the bulk of the subcutaneous flap pedicle at the glabella. However, suture lines were placed in the most inconspicuous sites in all patients, and the use of a trapdoor contraction emphasized the three-dimensional appearance of the nose. The use of these aesthetic subunits for reconstruction offers several advantages, particularly in Oriental patients. Because the nasal dorsum is reconstructed together with the side walls, tenting of the nasal dorsum is avoided, which prevents a flat appearance of the nose. A forehead flap is useful in the repair of complex defects. Defects of the alae should be separately reconstructed with a nasolabial flap to enhance the effect of the trapdoor contraction and to highlight the three-dimensional appearance of the nose. Candidates for reconstruction should be selected on the basis of nasal structure. The results suggest that these units can also be used in some white patients.     

Use of the radial forearm flap for deep,central, midfacial defects

Six cases that required soft-tissue replacement in the central midface are presented. The greatest number of flaps were used for large defects in patients with cleft palates who had undergone multiple previous operations. Several were for palatal defects attributable to cocaine abuse, and one was used for lining in a nasal reconstruction. There were no flap losses and, on the basis of these experiences, it is concluded that this is an excellent method for providing soft tissue in these difficult situations.     

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.     

One-stage closure of the entire primary palate

Timing of the closure of the anterior palate and alveolus is a subject of debate. Late repair of this defect is complicated by high fistula formation and subjects the patient to the problems of palate fistula for extended periods of time. We have utilized a single procedure performed when the child is 3 months of age that completely closes the anterior hard palate and alveolus along with the cleft lip. Our series consisted of 61 consecutive patients with unilateral clefts of the primary and secondary palate. Mucosal turnover flaps from the vomer along with lateral nasal mucosal flaps provide the nasal lining. A buccal sulcus flap with a Veau flap completes the oral repair. Ninety-five percent (58 of 61) of the patients had complete and stable closure of their anterior palate and alveolus after 1 year. The incidence of fistula formation in our series (3 of 61) is much lower than that reported with the utilization of other protocols. Excellent exposure of the anterior palate and alveolar defect during lip repair, early restoration of anatomic relationships, establishment of a good nostril floor and sill, and very low fistula formation are among the benefits of this procedure. The increase in operative time is considered minimal in light of aforementioned advantages.     

Nasal reconstruction: seeking a fourth dimension

A method of nasal reconstruction emphasizing the use of thin but highly vascular local lining and cover flaps to allow successful primary placement of delicate cartilage grafts is presented. The cartilage fabrication provides projection in space, airway patency, and, when visible through conforming skin cover, the delicate contour of the normal nose. Because tissue is replaced in kind and quantity, the need for multiple revisions to sculpt and debulk is decreased. Techniques and four case reports describe its applications to tip, heminose, subtotal, and total nasal defects.     

Combined anterolateral thigh flap and vascularized fibula osteoseptocutaneous flap in reconstruction of extensive composite mandibular defects.

Extensive composite defects of the oromandibular area are usually created after the surgical treatment of T3 and T4 cancers, requiring complex reconstructive plastic surgical procedures. The preferred treatment method for this type of defect is reconstruction with two free flaps. The use of the vascularized fibula osteoseptocutaneous flap for the bone and inner lining defect is well known and accepted. Among the flaps that can be used for the outer lining and soft-tissue reconstruction, the two most commonly used have been the forearm flap and the rectus abdominis myocutaneous flap. However, these flaps have some disadvantages that restrict their use for this purpose. The forearm flap is usually too thin to cover the fibular bone and reconstruction plate, and the rectus abdominis myocutaneous flap can cause a subclinical reduction in abdominal strength. Both radial forearm and rectus abdominis myocutaneous flaps are difficult to harvest during tumor excision. Because of these drawbacks, over the past several years the authors have preferred to use the anterolateral thigh flap for outer face, neck, and submandibular region reconstructions. From October of 1998 to June of 2000, 22 extensive composite mandibular defect reconstructions using the free anterolateral thigh flap, combined with the vascularized free fibula osteoseptocutaneous flap, were performed at the Chang Gung Memorial Hospital. Complete flap survival was 90.9 percent (40 of 44 flaps). Complete loss was seen in an anterolateral thigh flap, which was then reconstructed with a pectoralis major myocutaneous pedicled flap (2.3 percent). There were five venous problems: three in osteoseptocutaneous free fibula flaps, the other two in anterolateral thigh flaps; all were revised immediately. However, the skin islands of two osteoseptocutaneous free fibula flaps and one anterolateral thigh flap developed partial necrosis (6.8 percent). The other complications were compartment syndrome in the leg in one patient, external carotid artery rupture in one patient, three donor-site infections in two patients, three neck wound infections, and one myocardial insufficiency; all were treated properly. Thirteen patients underwent revision procedures 6 months after the first operation. These procedures included debulking of the flap or revision of the mouth angle or both. Trismus or intraoral contraction was noted in none of these patients. In conclusion, the free anterolateral thigh flap combined with the vascularized fibula osteoseptocutaneous flap seems to be a good choice in the reconstruction of the extensive composite defects of the oromandibular region aesthetically and functionally.     

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.     

Surgical correction of the severely deviated nose by extramucosal excision of the osseocartilaginous septum and replacement as a free graft

Twenty-five patients with severe internal and external deviation of the nose characterized by deviation of the septum in several planes and almost total obstruction of the airway on one or both sides were operated on. The entire bony and cartilaginous septum was removed in each of these patients, preserving the mucoperichondrial and mucoperiosteal flaps. The extramucosal technique of septal dissection was used. A support graft was fashioned from cartilaginous remnants of the septal cartilage and placed between the mucoperichondrial flaps as a free graft. All patients were followed for a minimum of 1 year. The longest follow-up is 15 years. Aesthetic improvement of the nose was obtained in all patients. All patients experienced varying degrees of improvement in nasal blockade.
