Deepithelialized turnover flaps in burns

Acute and chronic burns leave behind a full-thickness defect that always requires a flap cover. Such defects are common in electrical burn injuries of the limbs. This paper deals with 35 patients with full-thickness defects following burns in whom deepithelialized turnover dermis flaps and deepithelialized turnover flaps with deep fascia have been used. This flap is an extension of Hynes's reversed dermis graft and Smahel's deepithelialized turnover flap where there is a larger area of blood supply on the deeper aspect of the dermis. If a good hinge is provided for safe blood supply, such a flap settles well in the defect, and cumbersome multistaged procedures can be avoided. If there is less fatty tissue in the area of flap used, then reversed dermis flaps are ideal because split-skin graft take is good. When there is a lot of fatty tissue on the undersurface of dermis, the fascia is also included to make it a reversed fasciocutaneous flap to augment the blood supply and for better split-skin graft survival. Advantages of the procedure and complications are elaborated.     

Enhancing the take of injected adipose tissue by a simple method for concentrating fat cells

Injection of aspirated fat for the correction of tissue defects is a common procedure in plastic surgery. The reported rates of fat cell survival vary greatly in the medical literature, and different techniques of harvesting, processing, and reinjecting the fat cells are claimed to be responsible for these differences. However, there is no agreement concerning the best way to process the harvested fat before reinjection. The present study was initiated to examine and evaluate the effect of a simple method of isolating the fat particles on the outcome of fat graft survival. In this study, the nude mouse model was used to examine the survival and take of the fat graft concentrated before injection by the cumbersome recommended closed centrifugation technique in comparison with the authors' recommended open method, using an operating room cotton towel as a platform for concentrating the fat cells and separating them from fluids, oil, and debris. One milliliter of concentrated human fat cells preprocessed by towel separation was injected into the nuchal subcutis of 11 nude mice in the study group, and the same amount of fat that was preprocessed by centrifugation was injected into 11 control mice. Injected fat survived in both groups. No significant differences were found regarding fat graft weight and volume, although a tendency for better survival was noticed in the experimental group. Histologic evaluation of the grafts revealed significantly less fibrosis within the study group, meaning that the quality of the fat grafts was better. The authors found this method to be simple, cheap, and friendly to the surgeon in comparison with traditional processing using the centrifuge.     

A prospective, blinded, randomized, controlled clinical trial of topical negative pressure use in skin grafting

Topical negative pressure has been demonstrated to improve graft take in a number of noncomparative studies. This study aimed to assess whether split-thickness skin graft take is improved qualitatively or quantitatively with topical negative pressure therapy compared with standard bolster dressings. A blinded, prospective, randomized trial was conducted of 22 adult inpatients of Liverpool Hospital between July of 2001 and July of 2002 who had wounds requiring skin grafting. After grafting, each wound half was randomized to receive either a standard bolster dressing or a topical negative pressure dressing. Skin graft assessment was performed at 2 weeks by a single observer blinded to the randomization. Two patients were lost to follow-up and were excluded from the study. There were 20 patients (12 men and eightwomen) in the study group. The median patient age was 64 years (range, 27 to 88 years), and the mean wound size was 128 cm2 (range, 35 to 450 cm2). The wound exposed subcutaneous fat in eight patients, muscle in six patients, paratenon in four patients, and deep fascia in two patients. At 2 weeks, wounds that received a topical negative pressure dressing had a greater degree of epithelialization in six cases (30 percent), the same degree of epithelialization in nine cases (45 percent), and less epithelialization in five cases (25 percent) compared with their respective control wounds. Graft quality following topical negative pressure therapy was subjectively determined to be better in 10 cases (50 percent), equivalent in seven cases (35 percent), and worse in three cases (15 percent). Although the quantitative graft take was not significant, the qualitative graft take was found to be significantly better with the use of topical negative pressure therapy (p < 0.05). Topical negative pressure significantly improved the qualitative appearance of split-thickness skin grafts as compared with standard bolster dressings.     

Prefabricated temporalis fascia pedicled flap for previously skin-grafted contracted eye socket

The use of free skin, mucous membrane, or dermis-fat grafts in eye socket reconstruction proved to be unsatisfactory in long-term follow-up because of the progressive contraction of the socket. For achieving eye socket expansion of proper size and shape and a good vascularized lining that can last despite eventual fibrosis, a prefabricated temporalis fascia flap pedicled on the superficial temporal bundle is described in this report. In this technique, a split-thickness skin graft is applied over the termporalis fascia to create a sort of prefabricated flap, on which the proper dimensions of the socket can be fabricated on the grafted temporalis fascia. This study was conducted on 17 patients who had previously undergone eye socket reconstruction with skin graft after posttraumatic enucleation. All patients presented with a contracted eye socket, which manifested clinically by extrusion and migration of the ocular prosthesis. The procedure was performed in two stages. The purpose of prefabrication was to provide the proper shape and size of the newly created socket after release of skin-graft contracture to get a proper fit of the prosthesis, because the flap is thin and can be shaped well. The follow-up period ranged between 1 and 5 years, and the results were good.     

Meloplication of the malar fat pads by percutaneous cable-suture technique for midface rejuvenation: outcome study (392 cases, 6 years' experience)

The aging anterior midface is restored by reversing the contour undulations produced by sagging of the malar fat pad complex toward the nasolabial line. The convex irregularities include the exposed bulges of the post-septal fat, the unveiled malar bag, and the prominent nasolabial fold. The depressed irregularities are represented by the cresent-shaped hollow at the lid-cheek junction, the accentuated nasojugal groove, and the deepening nasolabial line. Repositioning of the ptotic malar fat pad, among other elements of meloplasty, represents a key procedure. In this study, the malar fat pad has been defined as a fan-shaped structure by external anatomic landmarks that correlate closely to the findings in cadaveric dissections and clinical cases, confirmed by the findings of spiral computed tomographic scanning. A simple but powerful adjustable and long-lasting percutaneous suture elevation technique was developed over the past 6 years by the senior author (G.H.S.) to reposition the fat pad in a superolateral direction. Through a dot incision within the nasolabial line, a permanent CV-3 Gore-Tex (or 4-0 clear Prolene) suspension suture, looped through a Gore-Tex anchor graft, suspends the malar fat pad in a direction perpendicular to the nasolabial line. A second suspension system is identically passed through another lower dot incision to broaden the repositioning vectors on the malar fat pad. Tension on each of the paired suture ends elevates the malar fat pad by 1 to 3 mm as measured from the nasolabial dot incisions. The sutures are fixed to the deep temporal fascia through a Gore-Tex tab, effectively stabilizing the soft-tissue repositioning. This maneuver may be performed in younger patients who present with an isolated malar fat pad ptosis without excess facial skin. The procedure may also be incorporated into open rhytidectomies to address this recalcitrant area along with superficial musculoaponeurotic system tightening. A total of 392 patients since 1995 underwent suture elevation of the malar fat pads. An outcome study indicated that the usage of two permanent sutures with Gore-Tex anchor grafts since 1998 resulted in improvement in midface rejuvenation of over 82 percent. Early and late complication rates were small and temporary. Patient acceptance was excellent, indicative of the benefits of anatomic repositioning of the malar fat pad complex.     

Lower eyelid reconstruction with a cheek flap supported by fascia lata.

The use of a cheek rotation flap is a well-known method for reconstruction of a large defect of the lower eyelid. In this technique, a separate lining tissue supporting the cheek flap is required for full-thickness reconstruction. Previously, a chondromucosal graft or conchal cartilage has been used to support this flap. Recently, we have used a homologous or autologous fascia lata as support for the cheek flap instead of rigid tissues like cartilages. A fascia lata strip is fixed with tolerable tension to the medial canthal tendon and lateral orbital rim. The inner surface of the fascia and the cheek flap is lined with a buccal mucosa graft to decrease irritation of the conjunctiva and cornea. We present here seven patients in whom this procedure was used for lower eyelid reconstruction following resection of a malignant skin tumor. Based on follow-ups of 7 to 22 months, the functional and aesthetic results have been good in all cases. This procedure may be applicable for total or subtotal reconstruction of the lower eyelid.     

Pinch skin grafting or porcine dermis in venous ulcers: a randomised clinical trial.

Chronic venous ulcers are common, and even with effective compression or elevation large ulcers may take months to heal. Pinch skin grafting may allow healing from epithelial islands throughout the surface area of the ulcer, and a prospective randomised trial was therefore conducted comparing this treatment with porcine dermis dressings. Most patients were treated as outpatients, 25 ulcers being randomised to treatment with pinch skin grafts and 28 to treatment with porcine dermis. Though the groups were well matched, the mean healing rate in the first week was 15 cm2 for pinch skin grafts compared with 3.5 cm2 with porcine dermis (p less than 0.02). By life table analysis 64% of ulcers treated by pinch grafts were healed at six weeks and 74% by 12 weeks compared with 29% and 46% of ulcers, respectively, treated with porcine dermis dressings (chi2 = 4.1; p less than 0.05). All ulcers that failed to heal within 12 weeks included an area posterior to the medial malleolus, where local compression may have been inadequate. Pinch skin grafting improves the rate of healing in large venous ulcers and is a simple technique that may be performed as an outpatient procedure under local anaesthesia.     

Experimental and clinical applications of fibrin glue

A 2-year experience with laboratory and clinical applications of fibrin glue is presented. An autologous technique, which eliminates the danger of multidonor preparations, has been developed in our blood bank. While one can obtain different fibrinogen concentrations from the same amount of a patient's blood, in vitro mechanical testing demonstrated that at higher fibrinogen concentrations there is an increase in shear adhesive strength. Evaluation of skin-graft take in 16 Sprague-Dawley rats did not demonstrate significant differences in healing when adhesive use was compared with suture technique. In a clinical study, four different groups of patients (facial burns, hand burns, difficult graft sites, and miscellaneous surgical applications) benefited from autologous or single-donor fibrin glue for a total of 82 cases. There are several distinct advantages to the use of fibrin adhesive: The autologous technique eliminates the risk of transmissible viral diseases (AIDS, hepatitis); it can be used as a sealant in the treatment of seromas, dural leaks, and lymphoceles; and it improves hemostasis and early graft adherence. Face and hands are resurfaced with sheet grafts in a single procedure, obtaining a better aesthetic result with complete graft take and immediate start of physical therapy. Neither sutures nor pressure dressings are required. The minimal postoperative care associated with early return to normal activities seems to increase the satisfaction of patients and nurse personnel.     

The relationship of the superficial and deep facial fascias: relevance to rhytidectomy and aging.

Controversy persists regarding the relationship of the superficial facial fascia (SMAS) to the mimetic muscles, deep facial fascia, and underlying facial nerve branches. Using fresh cadaver dissection, and supplemented by several hundred intraoperative dissections, we studied facial soft-tissue anatomy. The facial soft-tissue architecture can be described as being arranged in a series of concentric layers: skin, subcutaneous fat, superficial fascia, mimetic muscle, deep facial fascia (parotidomasseteric fascia), and the plane containing the facial nerve, parotid duct, and buccal fat pad. The anatomic relationships existing within the facial soft-tissue layers are (1) the superficial facial fascia invests the superficially situated mimetic muscles (platysma, orbicularis oculi, and zygomaticus major and minor); (2) the deep facial fascia represents a continuation of the deep cervical fascia cephalad into the face, the importance of which lies in the fact that the facial nerve branches within the cheek lie deep to this deep fascial layer; and (3) two types of relationships exist between the superficial and deep facial fascias: In some regions of the face, these fascial planes are separated by an areolar plane, and in other regions of the face, the superficial and deep fascia are intimately adherent to one another through a series of dense fibrous attachments. The layers of the facial soft tissue are supported in normal anatomic position by a series of retaining ligaments that run from deep, fixed facial structures to the overlying dermis. Two types of retaining ligaments are noted as defined by their origin, either from bone or from other fixed structures within the face.(ABSTRACT TRUNCATED AT 250 WORDS)     

Cultured epithelial autografts for giant congenital nevi

Eight pediatric patients with giant congenital nevi confluent over 21 to 51 percent body surface area were treated by excision and grafting. The nevus was excised to the muscle fascia, and the open wound was grafted with cultured epithelial autografts and split-thickness skin grafts. The patients have been followed from 17 to 56 months. Seventeen operations were performed in the eight patients, excising a mean of 6.9 percent body surface area at each procedure. The mean duration of anesthesia was 3.7 hours, and the mean operative blood loss was 12.3 percent estimated blood volume. The mean "take" for the cultured epithelial autografts was 68 percent, and for the split-thickness skin grafts, 84 percent. Epithelialization of open wound areas adjacent to the grafts was somewhat slower for the cultured epithelial autografts than for the split-thickness skin grafts, but it led to a healed wound in all patients except one. Ten of the 17 areas grafted with cultured epithelial autografts resulted in small open wounds that required regrafting. Wound contraction under the cultured epithelial autografts and under split-thickness skin grafts was similar and depended more on the anatomic site grafted than on the type of graft employed. in 16 of 17 operations, the cultured epithelium remained as a permanent, durable skin coverage. The use of cultured epithelial autografts allowed a larger area of excision than would have been possible with split-thickness skin grafts alone and, therefore, a more rapid removal of nevus. Cultured epithelial autograft are an important new technique in the care of patients with giant congenital nevi.     

Free anterolateral thigh adipofascial perforator flap

The anterolateral thigh adipofascial flap is a vascularized flap prepared from the adipofascial layer of the anterolateral thigh region. It is a perforator flap based on septocutaneous or musculocutaneous perforators of the lateral circumflex femoral system. With methods similar to those used for the free anterolateral thigh flap, only the deep fascia of the anterolateral thigh and a 2-mm-thick to 3-mm-thick layer of subcutaneous fatty tissue above the fascia were harvested. In 11 cases, this flap (length, 5 to 11 cm; width, 4 to 8 cm) was used for successful reconstruction of extremity defects. Split-thickness skin grafts were used to immediately resurface the adipofascial flaps for eight patients, and delayed skin grafting was performed for the other three patients. The advantage of the anterolateral thigh adipofascial flap is its ability to provide vascularized, thin, pliable, gliding coverage. In addition, the donor-site defect can be closed directly. Other advantages of this flap, such as safe elevation, a long wide vascular pedicle, a large flap territory, and flow-through properties that allow simultaneous reconstruction of major-vessel and soft-tissue defects, are the same as for the conventional anterolateral thigh flap. The main disadvantage of this procedure is the need for a skin graft, with the possible complications of subsequent skin graft loss or hyperpigmentation.     

The behavior of fat grafts in recipient areas with enhanced vascularity

Fat grafts are used for soft-tissue augmentation of various anatomic regions, most frequently for the improvement of facial contours. Resorption of the graft is the main problem, and several different procedures have been described to minimize this phenomenon. Using 25 New Zealand rabbits, the behavior of fat grafts in a highly vascularized recipient site was studied. The recipient sites prepared on the backs of the rabbits were divided into four regions. A capsule formation with silicone sheet application was accomplished in two of these recipient areas before the transplantation of the fat grafts. Fat grafts were placed in the other two recipient areas without any prior preparation. We prepared two types of fat tissue; in one the lobular structure was preserved and in the other it was manually crushed and rinsed with lactated Ringer's solution. The fat tissues with preserved lobular structure were placed in area I and area III. Manually crushed and rinsed fat tissues were placed in area II and area IV. In areas III and IV, a capsule formation with silicone sheet had been accomplished 3 weeks before grafting. Biopsy samples were obtained from these sites at the end of the first, third, sixth, and tenth months. Our aim was to observe the histologic fate of fat tissue in different recipient areas. The macroscopic and microscopic evaluation of the fat grafts in areas with silicone sheet indicated significant differences in the resorption time of the fat grafts; however, it was concluded that the significant resorption of the transplanted autologous fat tissue grafts at the end of the first year was an inevitable consequence of fat grafting.     

Take percentage and conditions of cultured epithelium were improved when basement membrane of the graft was maintained and anchoring mesh was added

To achieve a higher take rate for epithelial grafts, this study investigated grafting techniques. Seventy-seven nude mice received flap grafting in which cultured human epithelium was grafted inside the flap, and 55 nude rats received transplantation of epithelium to a full-thickness skin defect. In each group, four models were studied, including model 1, in which epithelium was cultured with the conventional method; model 2, in which epithelium was cultured with fibrin gel to avoid sheet damage, then absorptive mesh was incorporated into the epithelium for anchoring to the graft bed; model 3, in which epithelium was cultured with fibrin gel and combined with absorptive mesh and artificial dermis containing fibroblasts; and model 4, in which the model 2 epithelium was grafted after artificial dermis was transplanted. The take for these models was evaluated grossly and histologically. The results show that the take percentage of models 2 and 3 was significantly higher than that of model 1 (conventional epithelium) and that there was no significant difference between model 3 (simultaneous grafting) and model 4 (two-step grafting). The difference in the take percentages of the grafts to the flap and to the full-thickness skin defect was also insignificant. In immunohistochemistry, human keratin appeared in all epidermis layers and diversification of the layer was observed in models 2, 3, and 4. In these three models, type IV collagen appeared in the basal layer and the formation of basal membrane was confirmed. These findings suggest that epithelia cultured on fibrin gel and combined with absorptive mesh could be used in a new technique for better, more stable take.     

In search of improved fat transfer viability: a quantitative analysis of the role of centrifugation and harvest site

Fat grafting is an unpredictable procedure that continues to challenge the field of plastic surgery due to irregular resorption. Applications for this procedure are broad in both reconstructive and cosmetic plastic surgery. Fat grafts are carefully obtained and manipulated to obtain better graft takes and results, yet there is no universal agreement on what constitutes an ideal methodology. The present study examines adipocyte viability from four commonly used donor sites in five subjects. No statistical differences in adipocyte viability were demonstrated among abdominal fat, thigh fat, flank fat, or knee fat donor sites that were immediately removed and untreated (p < 0.225). In addition, no differences were observed in representative tissue samples that were removed and centrifuged (thigh, p = 0.508; knee, p = 0.302; flank, p = 0.088; abdomen, p = 0.533). On the basis of these quantitative data, neither harvest location nor centrifugation demonstrated any advantage in terms of lipocyte viability. Fat tissue transfers from these common sites may be considered equal, and centrifugation does not appear to enhance immediate fat tissue viability before implantation.     

Safety Concern between Autologous Fat Graft,Mesenchymal Stem Cell and Osteosarcoma Recurrence

Background

Osteosarcoma is the most common malignant primary bone tumour in young adult treated by neo adjuvant chemotherapy, surgical tumor removal and adjuvant multidrug chemotherapy. For correction of soft tissue defect consecutive to surgery and/or tumor treatment, autologous fat graft has been proposed in plastic and reconstructive surgery.

Principal Findings

We report here a case of a late local recurrence of osteosarcoma which occurred 13 years after the initial pathology and 18 months after a lipofilling procedure. Because such recurrence was highly unexpected, we investigated the possible relationship of tumor growth with fat injections and with mesenchymal stem/stromal cell like cells which are largely found in fatty tissue. Results obtained in osteosarcoma pre-clinical models show that fat grafts or progenitor cells promoted tumor growth.

Significance

These observations and results raise the question of whether autologous fat grafting is a safe reconstructive procedure in a known post neoplasic context.     

Increased free fat-graft survival with the long-term, local delivery of insulin, insulin-like growth factor-I, and basic fibroblast growth factor by PLGA/PEG microspheres

The present investigation evaluates the effects of long-term, local delivery of insulin, insulin-like growth factor-1 (IGF-1), and basic fibroblast growth factor (bFGF) on fat-graft survival using a poly (lactic-co-glycolic-acid)-polyethylene glycol (PLGA/PEG) microsphere delivery system. Twelve-micrometer PLGA/PEG microspheres incorporated separately with insulin, IGF-1, and bFGF were manufactured using a double-emulsion solvent-extraction technique. Inguinal fat from Sprague Dawley rats was harvested, diced, washed, and mixed with (1) insulin microspheres, (2) insulin-like growth factor-1 microspheres, (3) basic fibroblast growth factor microspheres, (4) a combination of the insulin and IGF-1 microspheres, and (5) a combination of insulin, IGF-1, and bFGF microspheres. The treated fat grafts were implanted autologously into subdermal pockets in six animals for each group. Animals receiving untreated fat grafts and fat grafts treated with blank microspheres constituted two external control groups (six animals per external control group). At 12 weeks, all fat-graft groups were compared on the basis of weight maintenance and a histomorphometric analysis of adipocyte area percentage, indices of volume retention and cell composition, respectively. Weight maintenance was defined as the final graft weight as a percent of the implanted graft weight. All growth factor treatments significantly increased fat-graft weight maintenance objectively, and volume maintenance grossly, in comparison with the untreated and blank microsphere-treated controls. Treatment with insulin and IGF-1, alone or in combination, was found to increase the adipocyte area percentage in comparison with fat grafts treated with bFGF alone or in combination with other growth factors. In conclusion, the findings of this study indicate that long-term, local delivery of growth factors with PLGA/PEG microspheres has the potential to increase fat-graft survival rates. Further, the type of growth factor delivered may influence the cellular/stromal composition of the grafted tissue.     

Neuromucosal prelaminated flaps for reconstruction of intraoral lining defects after radical tumor resection

To reconstruct intraoral lining defects after radical tumor resection by reinnervated vascularized mucosa, eight distal radial forearm flaps and two fibula flaps were prelaminated. Prelamination was performed by exposing the vascularized fascia, onto which the split distal end of a sural graft was fixed. The fascia and the sural nerve graft were covered by device-meshed mucosa or small full-thickness mucosa pieces. These structures again were covered by a Silastic sheet as large as the future flap, and the wound was closed by the elevated skin and subcutaneous tissue. Coverage by a Silastic sheet enabled mucosal spreading on the fascia, and the final flaps were thin, mucus-producing, and larger than the originally inserted mucosa. The 10 neuromucosal prelaminated flaps were harvested together with the inserted sural nerve graft after 8 to 10 weeks. During this time, the patient underwent radiotherapy and chemotherapy. Donor sites were closed directly by the preserved skin and subcutaneous tissue. Intraoral defects were reconstructed successfully by eight neuromucosal prelaminated distal radial forearm flaps and two neuromucosal prelaminated fibula flaps. The sural nerve grafts, inserted between the fascia and the mucosa, were coaptated eight times with the lingual nerve and two times with the inferior alveolar nerve. Intended reinnervation of the mucosa could already be proved clinically and histologically in the first two patients after 11 and 9 months. Preservation of skin and subcutaneous tissue considerably lowered donor-site morbidity. Neuromucosal prelamination enables reconstruction of intraoral lining defects by reinnervated mucus-producing tissue. Reconstruction of other mucosa-lined structures by this method seems feasible. Avoidance of skin islands for reconstruction lowers donor-site morbidity.     

Cytological and functional characteristics of fascia adipocytes in rats: A unique population of adipocytes

The dermal adipocytes, superficial fascia and subcutaneous adipose tissue (SAT) exist in the interspaces between the dermis and muscular fascia. They are adjacent to each other and traditionally recognized as one SAT. Recently, the dermal adipocyte was redefined as a unique population independent from the SAT. Also, we identified a novel type of adipogenic progenitors in rat superficial fascia. This study aimed to examine cytological and functional characteristics of fascial adipocytes in rats. Superficial fascia had no adipocytes in neonatal rats but gradually appeared numbers of adipocytes in growing rats. Adipogenic progenitors were found to reside in fascia and had strong ability in spontaneous and induced adipogenic differentiation in vitro. Differentiated fascial adipocytes versus subcutaneous or visceral adipocytes expressed increased adipose triglyceride lipase but decreased beta-adrenoreceptor, perilipin-1 and hormone-sensitive lipase (HSL), thus having high basal lipolysis but low lipolysis response to catecholamines. Phosphorylation of perilipin-1 and HSL and translocation of HSL to lipid droplets were attenuated in response to catecholamines rather than post-adrenoreceptoral lipolytic stimulators. The results suggested that superficial fascia was an origin of adipocytes with distinct developmental, cytological and functional characteristics. We proposed that fascial adipocytes could be considered as a unique population of adipocytes in the body. The fascia origin of adipocytes as an adipogenic model might logically explain fat neogenesis occurred at anatomical locations where originally exist no adipose tissues and thereby no adipose-derived stromal precursors. Also, the special histoanatomical relations and overlaps between the dermis, superficial fascia, SAT, and their adipocytes were discussed.     

Temporoparietal free fascia grafts in rhinoplasty

The temporoparietal fascial graft provides adequate coverage, contour, and bulk on the cartilage dorsum of the nose, as well as an inconspicuous donor site. In my opinion, this technique not only prevents the occurrence of noticeable sharp edges of the cartilage graft, but also adds to the smooth contour of the reconstructed nasal dorsum. The improved results either in primary and secondary rhinoplasty would seem to justify this technique. Some variations in fascia grafts are presented with clinical examples.     

Use of a temporoparietal fascia-covered silastic implant in nose reconstruction after foreign body removal

A total of 47 consecutive patients with paraffinoma of the nose underwent surgery for paraffinoma removal and insertion of temporoparietal fascia-covered Silastic implants between January of 1990 and June of 1996. There are several advantages to our procedure, and we obtained satisfactory outcomes with it. A bilateral alar rim incision was sufficient for our procedure. The Silastic implant could be sculptured easily, was not absorbed, and produced excellent cosmetic results. The fascia was highly bioadaptable and survived beneath the dermis through revascularization, even in the places where the paraffin material remained. The fascia reinforced the thinned skin that resulted after paraffinoma removal and, therefore, prevented exposure of the Silastic implant. The telangiectasia of paraffinoma of the nose improved in some patients after surgery.
