The "reading man" procedure: a new technique for the closure of circular skin defects

BACKGROUND: As most of the skin lesions tend to grow in a circular pattern, the resultant defects after surgical removal of these lesions are often circular. Although a number of local flap procedures have been described, alternative techniques are still needed for the closure of circular defects. PURPOSE: Here, a new surgical technique for the closure of circular skin defects is presented. This technique basically uses the extra skin relaxation gained with an unequal Z-plasty maneuver in favor of the defect closure. The procedure is named as "the reading man" because its surgical design resembles the silhouette of a man who is reading a book held in his hand. MATERIAL AND METHODS: In this technique, 2 flaps designed in an unequal Z-plasty manner are used. The first flap is transposed to the defect area whereas the second flap is used for closure of the first flap's donor site. For 3 years, this technique has been used for closure of the circular skin defects in 27 patients (19 men and 8 women) aged from 2 months to 68 years. The defect size was ranging between 1.5 and 14 cm in diameter. RESULTS: A tension-free defect closure was obtained in all patients. All flaps healed with no complications. There was no patient with dog ear formation. A mean follow-up of 15 months (6 months-3 years) revealed an esthetically acceptable scar formation in all patients. CONCLUSION: The reading man procedure was found to be a useful and an easy going technique for the closure of circular skin defects located on various anatomic regions. It enables surgeon to obtain a tension-free closure of considerably large skin defects with minimal scarring and additional healthy skin excision.     

Modified bilateral advancement flap: the slide-in flap.

The bilateral V-Y advancement flaps are used commonly in the closure of circular skin defects. We modified the standard bilateral V-Y advancement flap technique to reduce the tension along the closure, and used it in 10 patients between 1995 and 1997. In the presence of a circular defect, bilateral V-Y advancement flaps were marked on the skin, with the height of the V flaps measuring 1.5 to 2 times the diameter of the defect. The limbs of the V were not drawn as straight lines, but were curved outward slightly, making the flap and its two extensions broader than the standard V-Y flap. The broad extensions of the V flaps encircled the defect from above and below. Skin incisions were made vertically down to the muscle fascia. Additional undermining was carried out to elevate the upper and lower extensions of the V flaps for a distance that equaled the radius of the defect. The upper and lower extensions of the V flap on one side were transposed into the defect and sutured to the concave base of the opposing flap V flap at its midpoint. These extensions were then sutured to each other. The extensions of the opposing V flap were then transposed into the defect; the upper being superior and the lower being inferior to the extensions of the first flap. The rest of the operation was completed by advancement of the V flaps and closure in a Y configuration. The efficient redistribution of available tissue by the combined use of transposition and advancement principles resulted in the repair of relatively large skin defects with reduced tension along the closure. Satisfactory results were obtained in all patients in this series without any surgical complication.     

ISLAND FLAPS INCLUDING THE BEZIER TYPE IN THE TREATMENT OF MALIGNANT MELANOMA

Despite the trend in current surgical practice in the treatment of melanoma to produce smaller excisional defects, any technique which can introduce a surgical closure that does not require split skin grafting must be of benefit. This paper introduces and illustrates a range of island flap techniques that employ no skin grafting for the treatment of malignant melanoma defects. The new cutaneous island flap described, termed the Bezier or the French Curve, employs a double V-Y appositional closure method, thus giving a more refined reconstructive result that fits into the line of the body curves aesthetically. The design of the Bezier flap is almost identical in size and shape to the excisional defect, with a fascial or muscular base for vascular support. Appropriate guidelines that determine the design and application of this island flap technique are listed. They are illustrated both diagrammatically and clinically. Other flaps illustrated include fasciocutaneous island flaps and myocutaneous island flaps that use a single V-Y flap appositional closure technique. All these flaps were designed with special reference to the derma-tomes, which act as an aid memoire upon which the flaps are marked.     

Closure of large myelomeningocele by lumbar artery perforator flaps

Myelomeningocele is the most complex congenital malformation of the central nervous system that is compatible with life. Different closure techniques are available for defect reconstruction, but wound healing and tension-free closure of the skin in the midline remain major considerations in large myelomeningoceles. In this study, bilateral lumbar artery perforator flaps were used for closure of large myelomeningocele defects. Fifteen infants and neonates with large myelomeningocele defects were enrolled in the study. The lumbar artery perforator flaps were elevated bilaterally or unilaterally and advanced toward the midline without tension and were sutured together. Most of the flaps healed without any major complication. The lumbar artery perforator flaps as is an effective method for closure of large myelomeningocele defects.     

Epithelial lining methods in esophageal repair: a comparative study using pedicle flaps in cats

Methods of restoring luminal lining in repair of partial-circumferential esophageal defects were evaluated to compare incidences of strictures and fistulas and quality of surface lining. In cats 50% and 67% circumferential esophageal defects were repaired by direct closure or pedicle flaps (latissimus dorsi) that were unlined (lining restored by epithelialization from wound margins) or that carried lining of normal skin (myocutaneous flaps), skin grafts, or mucosal grafts. Repairs were evaluated for esophagocutaneous fistulas, luminal stricture, flap luminal surface area, and quality of epithelial surface 6 weeks after surgery. Direct closure of 50% circumferential defects was as satisfactory as any flap repair method. Direct closure of 67% circumferential defects caused high incidences of fistulas and strictures, which were lessened by flap reconstructions. Among flap lining methods, normal skin (myocutaneous flaps) gave the lowest incidence of fistulas and strictures and the highest surface quality, but a high incidence of skin paddle loss occurred in this model. Split-thickness epithelial grafts were nearly as satisfactory as myocutaneous flaps, and less lining loss occurred. Epithelialization of unlined flaps gave the poorest results since lining was thin and often incomplete, and wound contraction produced loss of surface area and strictures. The findings are discussed from a perspective of wound healing physiology, and implications for clinical application are presented.     

The helix flap for circular skin defects: case reports

After tumor resection, skin defects generally form circular shapes. However, closure of circular skin defect cannot be achieved satisfactorily by direct suture. Local flaps or skin grafts can be used to cover such defects. However, performing a graft or flap can require additional tissue resection to convert the flap’s shape to the defect’s shape. Reconstruction of these defects may cause problems such as distortion of anatomic points and extra normal skin resection. To solve those problems, a new local flap is reported; this is a combination of transposition, rotation, and subcutaneous flap techniques. This flap has been performed with success on various body surfaces for defects of a size ranging from 1.5 to 9 cm in diameter. In this paper, technical details and some clinical cases are presented.     

Bilateral, extended V-Y advancement flap

A modification of the V-Y advancement flap for the closure of circular skin defects is presented to decrease the tension in the closure and to break the midline vertical scar. Bilateral, extended V-Y advancement flaps with additional limbs extending to the advancing edges of the standard flaps were marked on both sides of the wound. After advancement of the V-Y flaps on their subcutaneous pedicle, the upper and lower extensions were hinged downward as transposition flaps to close the middle portion of the circular defect, where maximum tension occurs. This procedure was applied to 10 patients with sacral and trochanteric pressure sores. No complications or recurrences were noted during the 2 to 10 months of follow-up. Bilateral, extended V-Y advancement flaps enable the reconstruction of large defects without midline tension. Also, the resulting scar where the flaps meet is a zigzag line, so a straight midline scar is avoided.     

The role of soft tissue reconstruction after melanoma resection in the head and neck

INTRODUCTION: Reconstruction after wide local excision of melanomas in the head and neck can be formidable. Many tumors lie close to vital structures, and excision must carefully balance preservation of form and function. For small defects, primary closure or skin grafting is satisfactory. However, it has become increasingly evident that more advanced reconstructive procedures can improve the outcome in terms of both function and aesthetics. This study was undertaken to determine the effectiveness of flap closure after wide local excision of melanomas in the head and neck and to develop a set of surgical recommendations on the basis of our experience. METHOD: We reviewed 35 patients who underwent 39 flap closures at The University of Texas, M. D. Anderson Cancer Center after wide local excision of head and neck melanomas. Local flaps were primarily used to close defects after the resection of superficial or intermediate-thickness melanomas. Pedicle and free flaps were used to cover larger defects resulting from the excision of extensive tumors. The flap closures were compared with an analogous database of 560 melanoma resections that underwent primary closure or skin grafting. RESULTS: The mean age of the patient population was 57 years. The most common location for tumor presentation was the cheek, followed by the ear, forehead, and lip. Pathologic findings most commonly demonstrated superficial spreading melanoma, and the average defect size was 30.7 cm2. Local flaps were used most often for reconstruction. The only variable that significantly predicted local recurrence was the depth of the tumor. Local, pedicle, or free flaps did not decrease the ability of detecting local recurrence or increase this number compared with primary closure and skin grafting. Major postoperative complications were detected in seven patients. We found flap closure to achieve excellent functional and aesthetic results. CONCLUSION: Although primary closure is the ideal method of reconstruction for small defects, flap closure provides a versatile and safe alternative when simple closure would yield unsatisfactory results. With careful planning, flap closure offers an exceptional functional and aesthetic result and may even enhance contour defects after extensive neck or parotid dissections. Moreover, our experience with flap closure did not appear to delay the detection of local recurrence and may have even served to decrease the incidence of local failure after wide local excision of head and neck melanomas.     

Aesthetic repair of small to medium-sized nasal defects

Reconstruction of small and medium-sized defects of the nose poses a challenge to the facial plastic surgeon. Flaps for small to medium-sized defects most often are closed in single-staged procedures as opposed to larger-sized defects. A variety of techniques can be used including secondary intention, primary closure, full-thickness skin grafts, composite grafts, rhomboid flaps, bilobe flaps, dorsal nasal flaps, island flaps, and inferiorly based meliolabial flaps.     

Closure of large myelomeningocele defects using dorsal intercostal artery perforator flap

Small meningomylocele defects can be closed primarily. Other repair techniques are required for closure of meningomyelocele defects of >5 cm. In this anomaly, in which random or musculocutaneous flaps are usually used, the technique for skin defect closure should have the following criteria: a safely harvested flap with good blood supply; minimal morbidity in the donor site; closure with adequate thickness to protect the underlying neural structure; and a repair to prevent leakage of cerebrospinal fluid. The dorsal intercostal artery perforator flap is a new perforator flap with a large skin island that can be used safely in the dorsal region. In this article, repair of large skin defects due to myelomeningocele has been attempted using a dorsal intercostal artery perforator flap, and the results are discussed.     

Soft tissue closure and plastic surgical aspects of large dorsal myelomeningocele defects (review of techniques)

The large myelomeningocele defects that cannot be closed reliably by simple skin undermining require a close cooperation between the neurosurgeon and the plastic surgeon. In this study, a 3-year review was undertaken of nine consecutive patients with a myelomeningocele defect treated in our hospital. The aim of the study was to analyze the size, location of myelomeningocele defects, features of the surrounding tissue, and type and results of the reconstruction method for skin closure. Of the nine patients, five were repaired within the first 48 h of life, two within the 1st month of life, and two were repaired within the 1st year of life. Of the nine patients, seven (78%) underwent repair with direct skin approximation by the Neurosurgical Service. For three patients (33%) with large lumbosacral meningomyelocele defects, including one patient who had failed direct skin approximation, the Plastic Surgery Service achieved the skin closure by bilateral paralumbar fasciocutaneous rotational flaps. Minimal area in the patients referred to the Plastic Surgery Service was 24 cm² (range 24–48 cm²); patients having 18 cm² or less skin defect were not referred for closure. In conclusion, fasciocutaneous rotational flaps provided tension-free, durable, innervated and well-vascularized skin coverage over the dural repair in all three referred patients, without using skin graft. Since myelomeningocele defects vary in size, shape, and location, no single procedure applies to all. Therefore, other reconstruction methods involving skin grafts, fasciocutaneous flaps, and musculocutaneous flaps are reviewed in this report.     

The Modified Bilateral Advancement Flap

BACKGROUND: Bilateral advancement flaps are commonly used in the closure of circular skin defects because of their ease of execution and satisfactory result. However, the limited sliding capacity of these flaps has always been a problem. OBJECTIVE: The modified bilateral advancement flap maximizes the amount of tissue that can be brought into the defect. It relies on both advancement and transposition principles and borrows tissue from two planes. Thus the length of the flap could be shortened for increased flap survival. METHODS: Bilateral transposition flaps are created from tissue on both sides of the wound. These are then approximated and sutured together to form a single, new tip (apex), which is then advanced and sutured into the concave base of the opposing advancement flap at its midpoint. RESULTS: The modified bilateral advancement flap has been used effectively to close defects in the temporal, cheek, forehead, and lower eyelid, among 11 patients, providing a well-contoured and aesthetically pleasing reconstruction. CONCLUSION: This method extends the capacity of the bilateral advancement flap to reconstruct and improves its applications and advantages.     

Defektdeckung mittels Nahlappenplastiken im Gesicht

Local flaps for the closure of facial defects after trauma, tumor resection or due to malformations have been well known since ancient times and allow good to satisfying functional and aesthetic results. Based on the characteristics of skin and soft tissue nearly all clinical situations can be resolved by stretching, rotating and transposing flaps depending on the localization. A good surgical technique is essential for the success. The basic principles are briefly described and suggestions for the application of flaps to different localizations are given. For analgesia local anesthesia is sufficient. As could be demonstrated multitudinously the method is ideal for closure of small to large defects in the face; therefore, microvascular surgery can be extremely restricted in treating defects of the face.     

Intraoral and oropharyngeal reconstruction using a de-epithelialized forearm flap

We have used free forearm flaps for closure of various intraoral and oropharyngeal defects after radical ablation of tumors. A problem remained, however, in that split-thickness skin grafts required to close the forearm defect had to be obtained from other areas. To avoid this disadvantage, we de-epithelialized forearm flaps and the donor defects were closed with the split-thickness skin obtained from flap de-epithelialization. As a result of this procedure, unnecessary scarring has been avoided and postoperative management has been simplified. Such complications as flap loss, fistulae, or scar contracture have not occurred with greater frequency than is seen in normal circumstances. The de-epithelialized forearm flap procedure is explained. Histological findings concerning the de-epithelialized forearm flap are described, and the advantages of this method stated.     

Subcutaneous V-Y advancement flap for closure of nasal tip defect

Our experience with V-Y subcutaneous flaps for nasal tip closure after tumor resection in 10 patients is reported. This method has distinct advantages over previously used methods such as skin graft, rotation, or transposition flap. It allows primary closure of recipient and donor site without the formation of dog-ear or trapdoor deformity. It is easy to design, reliable, and offers good cosmetic results. This method is performed under local anesthesia as an office procedure. It is recommended to plastic surgeons for the closure of nasal tip defects.     

The 180-degree perforator-based propeller flap for soft tissue coverage of the distal, lower extremity: a new method to achieve reliable coverage of the distal lower extremity with a local, fasciocutaneous perforator flap

BACKGROUND: Traumatic and nontraumatic defects of the distal third of the tibia are challenging in regard to soft tissue coverage. While local, pedicled fasciocutaneous perforator flaps allow adequate coverage, the donor site often requires skin grafting. When a local perforator flap is designed as a 180-degree propeller flap, an excellent esthetic result and direct closure of the donor site can be achieved, with minimal morbidity. METHODS: Eight patients with defects in the malleolar region were treated with 180-degree propeller flaps based on perforators from the tibial and peroneal vessels. RESULTS: One partial flap loss was encountered in an insulin-dependent diabetic. Partial superficial epidermolysis was encountered in 2 cases and healed without further interventions. No other complications were encountered. All patients returned to full ambulation within 8 weeks. CONCLUSION: The 180-degree propeller flap is an elegant and versatile method to achieve soft tissue coverage with local tissue in defects of the distal tibia. Contrary to other local perforator flaps, this specific design facilitates direct closure of the donor site. As only local, thin tissue is used, no interference with normal shoe wear occurs. Even in older patients, this flap has proven to be a reliable option.     

The versatility of the hatchet flap in soft tissue reconstruction and a proposed new classification

The Hatchet flap is a well-known flap used to cover round defects with primary closure of the donor sites in a V–Y fashion. This provides a stable coverage of the defect by a skin flap from the adjacent area and thus having similar color, texture, and sensation to the lost skin. Literature showed the application of the hatched flaps in facial, fingertip, pressure sores, and meningomyelocele reconstruction but not in the other anatomic areas. The aim of this study was to demonstrate the versatility and reliability of two types of hatchet flaps to reconstruct soft tissue defects at various anatomical regions of the body. Forty-six hatchet flaps were used in 40 patients to reconstruct defects located at scalp, face, neck, chest, axilla, back, sacrum, trochanter, genitalia, perineum, buttock, thigh, knee, foot, and fingertip. The causes of defects were infection, trauma, tumor excision, pressure necrosis, congenital meningomyelocele, chemical burn, and radiation. Mean follow-up period was 6.6 months. Hatchet type I flaps were advanced without undermining using the viscoelastic properties of the skin, while hatchet type II flaps were undermined before rotation advancement. All defects were successfully covered. The flaps survived completely. Partial dehiscence occurred at the donor site of three flaps but healed without problems after re-suturing. In conclusion, hatchet flaps are versatile flaps that provide a simple but efficient solution to defects of different etiologies located at different anatomical regions in the body. Minimal blood loss and short duration of surgery make them first option flaps for patients with co-morbidities.     

Local Hatchet Flap for Facial Skin Defects Reconstruction in Special Areas

BACKGROUND: The local hatchet flap has been used to reconstruct skin defects of the face with satisfactory results. Cosmetically, it has advantages over other local flaps when skin defects are located in special areas such as the eyelid. OBJECTIVE: The purpose of this study was to examine the application of local hatchet flaps for facial defect reconstruction, especially in cases where reconstruction is classically difficult for cosmetic and functional rehabilitation. METHODS: We report an illustrated case series. Results. In this study, all four cases achieved satisfactory functional and cosmetic results using the local hatchet flap. CONCLUSIONS: The local hatchet flap is an effective and simple alternative for reconstructing facial defects in special areas of the face, offering good cosmetic results and satisfactory function.     

Early coverage of deep hand burns with groin flaps

Deep burns of the hands require skin flap coverage in order to protect the exposed vital structures. The groin flap is a safe and effective method of obtaining early closure of these defects. We have used groin flaps to cover deep hand burn defects in nine patients. In each case, groin flaps effectively covered the various defects, such as the volar aspect of the wrist, dorsum of the hand, first web space, thumb, and fingers.
