This article reviews the indications and techniques for performing a bilobed flap for reconstruction of surgical wounds. Various examples of surgical defects where a bilobed flap can be used are shown. Possible complications and pitfalls are also reviewed The bilobed flap is a random-pattern double transposition flap. The key principles to this repair are 5,6,7: First lobe fills the primary defect, second lobe fills the secondary defect. Double transposition will distribute tension to wider area of skin The bilobed transposition flap began as a technique to repair the nasal tip. The purpose of our review is to catalogue the successes of the bilobed flap since it was first described by Esser in 1918, as well as the modifications created by other physicians since then
A double transposition flap with a stable stem from a subcutaneous vascular plexus and depending on the localization including muscle fibers. The tissue is rotated through an angle of about 90-100° into the defect. This section has been translated automatically. The bilobed flap is often used to cover defects on the nose, but also on the cheek. The bilobed flap is a local transposition flap useful for the repair of nasal defects commonly seen after Mohs surgery. The bilobed flap has benefits over other nasal transposition or advancement flaps because it distributes wound closure tension over a larger surface area through the use of 2 lobes The bilobed flap is a double-lobed modification of the banner transposition flap described above. The principle of transposing skin from an area of laxity remains the same; however, the transfer of..
The proposed technique involves designing and carving a modified bilobed flap that uses redundant skin at the lower ear pole. The flap consists of fat skin tissue and has two wings identical in size, designated A and B (Fig. 1). This provides two branches, a and b, which, once sutured, constitute the curved earlobe free edge. Fig. 1. A bilobed flap with the first lobe at 80% of the defect at a 30-40 degree angle and the second lobe at 80% of the donor site at a 90 degree angle to the original lesion. These were elevated using sharp and blunt scissors dissection. Dissection was then used to elevate the skin around the margin. Cautery was used to control bleeding A transposition flap is cut, lifted, and transferred over intervening tissue onto the defect. This type of flap is also referred to as a rhombic, bilobed, or nasolabial fold flap. And with an advancement flap, tissue is moved in a straight line and stretched over the defect. This is also referred to as a V-Y repair or flap - Rhombic Transposition flap - Bilobed transposition - Nasolabial transposition Tissue reorientation flaps are characterized by the lifting of skin from an adjacent donor site and reorienting it through the transposition of the flap over a peninsula of skin between the donor site and the defect. There is a pivot point at the base of this flap. The bilobed flap is a double transposition flap commonly used in reconstruction of facial skin defects. The bilobed flap allows for the movement of more skin over a longer distance than that possible with a single transposition flap
Bilobed Flap. An interesting flap design is the bilobed flap described by Esser (1918). The two flaps have a common base and form an angle between 45° and 180°. Smaller angles make it easier to rotate the two attached transposition flaps (Fig. 3.23), while larger angles require longer flaps and cause greater skin bunching In this paper, we present our experience with the use of the Zitelli bilobed flap, which is defined as a double transposition flap for the reconstruction of the nose defects The bilobed flap is a double transposition flap where the first flap (or lobe) serves to fill the primary defect, and a further flap (or lobe) fills a secondary defect. This approach seeks to distribute tension across a wider area. It is a random pattern flap. The random pattern nature of the flap means that the flap has no specified blood supply
The bilobed flap is a double transposition flap commonly used in reconstruction of facial skin defects. The bilobed flap allows for the movement of more skin over a longer distance than that.. The bilobed flap, as Esser first described, comprises 2 flaps identical in size and form and separated by angles of 90°, as seen in the image below. Skin is transposed over 180°
The bilobed flap is a random-pattern cutaneous transposition flap consisting of two lobes based on a single pedicle. Although the bilobed flap has been used in sites as disparate as the face, eyelids, trunk, foot, scalp, and hand, its greatest use is in nasal reconstruction .5 and 1.5 cm. By enabling the transposition of skin over a larger distance than would be possible via a single flap, the bilobed flap allows for the use.
The bilobed flap can effectively transfer tension across a larger angle of rotation and thus distributes the load more evenly. With this in mind, let us take a closer look at the use of a bilobed transposition flap to help heal a wound plagued by chronic recurrence for five decades The bilobed flap, as reported in this case, is considered a rotational and transpositional cutaneous flap, with two lobes and only one random pedicle. 1,7 It is classically described for nasal reconstructions, and lately for other anatomical sites such as dorsal area of the hand, malar region, palpebral, retro-auricular, axillary, plantar.
The most commonly used flap was the bilobed double transposition flap that is especially useful for reconstruction of defects on the lower third of the nose. While the standard design often results in tissue protrusions or pincushioning, improvements in the design are outlined herein to achieve the best results for defects on the nose transposition ﬂap for medial canthal reconstruction. Esser de-scribed a ﬂap of 2 lobes of the same size, angled at 90 and 180 degrees to the site of the defect. More recent modiﬁcations use narrower angles to avoid dog-ear formation and create less tension.14 Sullivan and Bray5 described 36 bilobed-ﬂap media

Free ﬂap Patel and Sykes Local Flap Design and Classiﬁcation 1 The trilobed flap's design and execution leverage the strengths of the bilobed flap to allow application to a broader range of surgical nasal defect sizes and locations, particularly distal defects. OBJECTIVE To present our surgical execution and application of the trilobed flap for reconstruction of distal nasal Mohs surgery defects The rhomboid flap is a local transposition flap - a flap that moves laterally about a pivot point into an adjacent defect. This lateral movement differs it from a rotation flap. The donor site wound is closed directly under minimal tension. Other examples of transposition flaps include: Bilobed Flap. Z-plasty Zimany  popularized use of the bilobed flap & defined this as a flap consisting of 2 lobes separated by an angle & based on a common pedicle. Relevant Anatomy. Bilobed flap is a random transposition flap because blood supply does not arise from a segmental artery & no defined pedicle is present The Bilobed Flap. This double transposition flap was first described by Esser in 1918. 28 Modification of the bilobed flap by Zitelli 29 made it an ingenuous technique for reconstruction of defects of the caudal aspect of the nose. 29 He reduced the pivotal angle from 180 o to 90 o, thus minimising donor site distortions which gives a good.
There are many reasons why there may be asymmetry after a bilobed transposition flap, some of these resolve with time, some with treatment and some may not resolve completely. The best starting option is to return to the doctor who performed the reconstruction and discuss what has happened and what can be done The bilobed flap is a random-pattern cutaneous flap consisting of two lobes based on a common pedicle. It is a double transposition flap and is the epitome of the Robin Hood concept of flaps—that is, taking tissue from where there is abundance and laxity and moving it to an area where there is a paucity of tissue The most common transposition flaps in cutaneous surgery include rhombic flaps (and their variations), bilobed flaps, and banner flaps such as the nasolabial flap. Knowledge of the tissue dynamics used in these three basic transposition flaps can be carried over to the planning and execution of numerous flap variations

The tissue efficiency of common reconstructive design and modification Aim: The correction of nasal tip defects presents many challenges. Zitelli's bilobed flap has been widely used for such repairing defects, but may be complicated by interrupted scars on the nasal dorsum. Our study evaluates the design principles, results, and advantages of a modified bilobed flap for repairing nasal tip defects. Methods: The primary lobe was located between the defect and the. Authors : N. Hokayem MD PhD, J. El Khoury MDThis video shows how to perform a nasal reconstruction with a simple bilobed flapCome and visit us on wikiplastic.. The bilobed flap is a special type of transposition flap. All flaps are restricted in motion at the flap's point of rotation or transposition; this restriction has been termed pivotal restraint .Thus, the primary lobe of the bilobed flap effectively undergoes flap shortening as the primary lobe is transposed into the primary defect
THE ADAPTABILIT Y AND UTILIT Y OF THE BILOBED TRANSPOSITION FLAP Abstract The bilobed transposition flap began as a technique to repair the nasal tip. The purpose of our review is to catalogue the successes of the bilobed flap since it was first described by Esser in 1918, as well as the modifications created by other physicians since then. A PubMed Search from 1900 to 2015 for the words. The bilobed flap, originally described by Esser, is a special type of transposition flap. It is an extremely useful technique as it effectively transfers tissue from areas of abundance to areas of deficiency Other single-transposition flaps such as rhomboids are less effective in the lower third of the nose, in which the tight skin limits flap rotation and tends to cause more tissue protrusion around the pivot point. The main reported disadvantages of the Zitelli bilobed flap are distal flap tension resulting in retraction and pincushioning The bilobed transposition flap began as a technique to repair the nasal tip. It is an extremely versatile procedure that has expanded its scope over the entire body. Methods. A PubMed Search from 1900 to 2015 for the words bilobed flap yielded 132 results—31 of the nose, 7 of the ear, 11 of the forearm, 19 of the hand, 9 of the cheek. bilobed flap a transposition flap consisting of two lobes: a large lobe that is transposed into the primary defect and a second, smaller lobe that is transposed to fill the defect left by mobilization of the large one..

The primary flap was rotated to repair the surgical defect, and the secondary flap was placed to close the primary flap donor site. The defect from the secondary flap was undermined and closed primarily. The geometric design and biomechanics of the bilobed flap ad its release of tension are similar to those of the Z-plasty transposition flap. Applying key principles to the design and execution of transposition flaps results in reliable outcomes. Conclusion Carefully designed and executed rhombic, bilobed, and trilobed transposition flaps provide an excellent reconstruction option when tension at a cutaneous defect is too great for primary closure Local Flaps I: Bilobed, Rhombic, and Cervicofacial. This article is the first in a series focusing on the reconstruction of defects of the head and neck created by the resection of a skin cancer. This series begins with a detailed description of specific types of local flaps, and is followed by articles emphasizing the options for.
A number of modifications to the standard transposition flap have been described and many have been used in the foot. These modifications include rhomboid flaps, bilobed flaps, and Z-plasties . Transposition flaps move over adjacent intact skin to close a defect and combine the use of both rotation and advancement. These flaps include the. The following article presents a comprehensive review of rhomboid flaps in the English literature and discusses the indications, applications, and results. Nearly 100 years after it was first described by A.A. Limberg, the time has come to embrace this simple and elegant flap as the preferred method of reconstruction of cutaneous defects of any. 9.

An ulnar transposition flap may be used to close a small residual donor defect. An ulnar immobilizing splint is then applied for approximately 1 week. The wrist is in slight extension to eliminate dead space between the brachioradialis and flexor carpi radialis muscles, where a hematoma may form The bilobed flap is a double transposition flap commonly used in reconstruction of small-to-medium skin defects of the face where skin is less mobile. However, larger defects can also be effectively treated with a bilobed flap in certain cases. The classi
An advantage of the bilobed flap is that most of the incisions necessary to create the flap produce scars that can be placed parallel to relaxed skin tension lines . Moreover, the second lobe of the transposition flap reduces the overall wound closure tension and provides additional skin to the proximity of the reconstruction [ 7 ] traditional bilobed flap. (C) This surgery resulted in a cosmetically and functionally good outcome at a 5-month follow-up. tropion and deformities of the eyelid margin1. This leads to difficulties in properly designing local flaps1,2. Bilobed flaps are a double transposition flap using relatively loose tissue, mainly from the glabella or nose3. The bilobed flap is a double transposition flap with a single pedicle in which the first flap is transposed into a defect and the second, smaller flap is transposed to fill the secondary defect caused by the larger flap transposition. Thus, the forces of tension are distributed in various directions, and the skin distortions and redundancy.
The Zitelli bilobed flap has been described for defects of the lower third of the nose that are 1.5 cm in diameter or smaller. Unfortunately, because of loss of length with transposition, use of this flap can lead to alar retraction, which some have proposed to bypass by lengthening the flap.8 We hypothesized that a longer primary flap Transposition flap (Fig 18 E): In these flaps, the skin not directly adjacent, but close to the defect, is lifted over the intervening skin and fitted into the defect. Bilobed flap (Fig. 20): The bilobed flap was originally described by Esser in 1918 for reconstruction of defects of the nasal tip. This flap is widely used for circular. bilobed flap — a transposition flap consisting of two lobes: a large lobe that is transposed into the primary defect and a second, smaller lobe that is transposed to fill the defect left by mobilization of the large one.

It is possible that with time (and perhaps intralesional steroids, massage) the appearance will improve. It takes 6-12 months to reach the final result after reconstructive surgery. If things don't improve or you lose confidence in the first doctor, get a second opinion from somebody who does a lot of reconstruction and bilobed transposition flaps Watch Dr. Steven Swaim demonstrate how to perform this wound reconstruction technique, helpful for when you need to repair a square or rectangular wound and. Analysis of the Effects of Graded Skin Thickness on Mechanical Strain of the Bilobed Transposition Flap. American Academy of Dermatology Annual Meeting, San Diego, CA. February 2018; Gruber PJ, Armbrecht E, Maher IA. Analysis of the Effects of Graded Skin Thickness on Mechanical Strain of the Bilobed Transposition Flap the bilobed flap offers distinct advantages over alternative repairs: access to an adjacent tissue reservoir with similar aesthetic qualities, predictable flap viability, and the reduced morbidity of a single-stage procedure.3 In the traditional design, the vascular inlet, or base, of the bilobed flap is located laterally, where tributaries of. bilobed transposition flap for helical ear reconstruction. added by lbugatti.

Upper lateral cheek defects may be reconstructed with a rhomboid or bilobed flap. However, these flaps are prone to pincushioning and bring paler skin into the more erythematous malar region, thus making the reconstruction obvious. Both flaps might end up with undesirable transposition of hair-bearing areas into non-hair-bearing area With transposition flaps, the position of the main tension vector is changed from the primary defect to a more ample adjacent tissue reservoir, and the elevated flap is transposed under little to no tension. The ability of transposition flaps to push tissue into the defect by redirecting tension vectors perpendicular to the primary closure. One of the methods frequently utilized to manage contractures in this area are skin transposition flaps harvested from dorsal radial aspect of the index finger. In this study, we present our results with bilobed flap modification of the dorsoradial transposition flap we designed to facilitate the transposition of the flap and to minimize the. The rhomboid (Limberg) flap is a transposition flap that, like the bilobed flap and the Z-plasty, depends on the pliability of the adjacent skin, which can be determined by pinching various areas between the thumb and forefinger (2) the bilobed flap has comparable features to the hatchet flap for lower lateral nasal defects , the trilobed flap can be compared to the dorsal Result Both the bilobed and trilobed flaps contain significant elements of rotation and transposition in their design, in addition to an important but subtler element of advancement .Taking.
This patient underwent a neck transposition flap, and forehead and cheek rotation flap procedure to close this large defect. This 52-year-old woman had a squamous cell carcinoma removed from the right side of her nasal tip. A bilobed flap procedure was performed. The after photo shows the patient's result six months after surgery with no. The bilobed transposition flap. The primary donor flap is designed tangential to the defect, and the secondary flap is designed to be smaller and more elliptic to allow for primary closure of the secondary donor site. Rhomboid Flap Rhomboid flaps (Fig. 3)21-25 are rhomboid-shaped skin flaps transposed into like- shaped defects leaving an. nasolabial flap or forehead flap . The bilobed flap was first described by Esser in 1918 for use in nasal tip defect reconstruction, it was a double transposition flap using two adjacent skin flaps at 90° to one another with a total rotation of 180°, this flap design produced severa Transposition slap • Limberg Flap • Bilobed Flap • Pectoralis Major Flap • Z-Plasty.

From the type of flap described above, a variant has been developed; in this case the alignment occurs with a second accessory lobe when the lesions between them are more distant . Figure 26. A graphic representation of coaxial transposition bilobed flaps. This variant can also be applied to cases in which. The most commonly used local flaps in nasal reconstruction; bilobed, rhomboid, advancement, dorsal nasal and transposition flaps. Nasal dorsum skin is thin and mobile. Dorsal nasal flap, glabellar flap, forehead and full thickness skin could also be preferred for reconstruction of this region
The SENMI flap offers a unique alternative to the forehead flap for nasal reconstruction. It also supplants some indications for nasolabial fold transposition flaps and bilobed flaps. In some cases, the SENMI flap can be used for reconstruction of alar rim full thickness defects in conjunction with other internal lining techniques The repair of large or deep alar defects following the surgical removal of melanoma and nonmelanoma skin cancer can be challenging. The repair of such defects has been largely dominated by the use of the nasolabial transposition flap, bilobed flap, and forehead flap. For smaller or more superficial defects, second intention and skin grafts are commonly used.The tunneled island pedicle flap. Rhomboid flaps may even be combined with nasolabial flaps for the repair of lateral nasal defects. 26 BILOBED FLAP The bilobed flap is a double transposition flap first described by Esser to reconstruct nasal tip defects. 28 It is a random pattern, single-stage flap, lacking a large-caliber vessel in its base The rhomboid flap of Limberg is a. The bilobed flap, as reported in this case, is considered a rotational and transpositional cutaneous flap, with two lobes and only one random pedicle. 1, 7 It is classically described for nasal reconstructions, and lately for other anatomical sites such as dorsal area of the hand, malar region, palpebral, retro-auricular, axillary, plantar. Glabellar flap can be raised as a V-Y advancement flap, transposition flap, or a V-Y rotation advancement flap depending on the defect size and location. V-Y advancement flap. Outlining the flap.
