RESUMEN

BACKGROUND: In recurrent hypopharyngeal/laryngeal squamous cell carcinoma after radiation salvage-laryngectomy (salvage-LE) represents the best curative treatment option. Pre-irradiation promotes development of pharyngocutaneous fistulas (pc-fistula). Transfer of unirradiated tissue to the surgical site reduces fistula rate. Frequently, a myocutaneous Pectoralis-major-flap (PMF) is applied. We describe a muscle sparing, myofascial PMF (ms-PMF) and its functional & aesthetic results. METHODS: For the ms-PMF, the pectoralis major is exposed via two 8 cm long subclavicular & submammary horizontal incisions. The pectoral branch of the thoracoacromial artery, which represents the blood supply for the ms-PMF, is identified between the clavicular and sternocostal aspect of the muscle. A craniocaudal stripe of the pectoralis major is recovered and supraclaviculary transposed towards the pharynx. The clavicular and sternocostal part of the muscle remain untouched.The clear-margin resection rate (CMRR), mean overall survival (OS), complications, median length of hospital stay, & functional & aesthetic outcome were assessed. RESULTS: In 25 patients, salvage-LE with ms-PMF was performed. The CMRR was 100 %, median OS 1.3 (follow-up 2.8) years, complications rate 16 % (4 complete lobe necroses, 3 pc-fistulas) and median inpatient stay 20 (11-78) days. Good functional outcome were observed: limitations of oral food intake occurred in 2-, limitations in voice rehabilitation in 3 patients. Wound healing disorders without lobe necrosis were not observed. The aesthetic results were appealing. CONCLUSION: The ms-PMF is a less invasive & safe procedure for fistula prophylaxis in salvage-LE with favorable functional & aesthetic results.

RESUMEN

BACKGROUND: Pectoralis major flap reconstruction is often associated with large unappealing scars in head-neck surgery. We recently established an alternative harvesting technique that improves aesthetic outcome. OBJECTIVES: The objective of this study was to demonstrate a modified surgical technique that harvests the pectoralis major muscle as an island flap and focuses on minimizing incision lines and applying a muscle-sparing approach. METHODS: A retrospective analysis covering the period 2008-2018 was conducted. Patients who underwent pectoralis major island flap reconstruction for fistula prophylaxis after salvage laryngectomy at the Medical University of Innsbruck were included. Flap harvesting was performed subcutaneously using two small incision lines, thereby sparing the clavicular and upper sternocostal aspects of the pectoralis muscle. RESULTS: Twenty-three patients with squamous cell carcinoma of the larynx (n = 19) or pharynx (n = 4) underwent salvage laryngectomy and consecutive reconstruction using a pectoralis major island flap and our muscle-sparing technique. Mean overall operation time was 147 ± 48.6 min. The majority (70%) of patients had an uneventful course of recovery and showed satisfying aesthetic results and low donor site morbidity as compared to traditional harvesting techniques. Six (26%) patients had major complications that required surgical revision. Three (13%) cases were complicated with fistulas. CONCLUSION: The pectoralis major island flap is shown to be reliable in otolaryngeal surgery. This surgical technique minimizes scarring and preserves thoracic wall architecture by taking a less invasive approach, thereby improving aesthetic outcome and reducing overall patient morbidity.

RESUMEN

Postoperative wound-healing problems are relatively high in post-bariatric body-contouring procedures, partly because of electrosurgery and the associated thermal tissue damage. This study is a retrospective randomised evaluation of the effect of a low-thermal plasma dissection device (PEAK PlasmaBlade, Medtronic, Minneapolis, Minnesota) in comparison with conventional electrosurgery. A total of 24 patients undergoing upper arm or medial thigh lifting were randomised to PEAK PlasmaBlade on one side and to monopolar electrosurgery on the other side of the same patient. Wounds of 10 patients were examined histologically for acute thermal injury depth. Significantly lower total volume of drain output (61,1 ± 70,2 mL versus 95,1 ± 176,0 mL; P = .04) was found on the PEAK PlasmaBlade side compared with the electrosurgery side. Furthermore, the PEAK PlasmaBlade side showed fewer seromas (no case of seroma versus three seromas in the electrosurgery group) and less thermal damage (40% versus 70%; P = .26). Acute thermal injury depth from the PEAK PlasmaBlade was less than from monopolar electrosurgery (425 ± 171 µm versus 686 ± 1037 µm; P = .631). PEAK PlasmaBlade appears to be superior to traditional monopolar electrosurgery for post-bariatric body-contouring procedures because it demonstrated less tissue damage, lower total volume of drain output, and fewer postoperative seromas resulting in faster wound healing.

RESUMEN

OBJECTIVES: Postoperative pain management is of utmost interest for patients undergoing orthognathic surgery. Currently, there is a lack of information regarding process and outcome parameters of postoperative pain management after bilateral sagittal split osteotomy. MATERIALS AND METHODS: In a prospective clinical study, 31 adults were evaluated on the first postoperative day following bilateral sagittal split osteotomy using the standardized questionnaire of the Germany-wide project Quality Improvement in Postoperative Pain Management (QUIPS). It allows a standardized assessment of patients' characteristics, pain parameters, outcome, and pain therapy process parameters. RESULTS: Pain management consisted mainly of premedication with midazolam, sufentanil, and metamizol intraoperatively; piritramide in the recovery room; and metamizol and tramadol on ward. Twenty patients (64.5%) showed inadequate pain management with pain levels ≥4. Patients receiving tramadol as opioid on ward presented significantly higher maximum pain levels (p = .037). Significantly lower satisfaction with postoperative pain intensity (p > .001) and significantly higher desire for additional pain medication (p = .023) were detected, when duration of surgery was above the median of 107.5 min. CONCLUSIONS: Inadequate pain management on the first postoperative day following bilateral sagittal split osteotomy was widespread on our ward. QUIPS helped us to identify it and thereby gave us the possibility to improve the situation. Prolonged duration of surgery seems to be a predictor of an elevated postoperative pain medication demand. CLINICAL RELEVANCE: Only the establishment of an ongoing monitoring of postoperative pain management can help to reduce or even avoid inadequate postoperative pain management. In accordance to the existing literature, we found inadequate postoperative pain management more widespread than thought.

RESUMEN

BACKGROUND: The free radial forearm flap phalloplasty is the most utilized method for penile reconstruction. Among the techniques described in the literature, evidence for the flap design after Gottlieb and Levine is poor. METHODS: From January 1993 until December 2015, 402 phalloplasties were performed in our clinic. Among the 247 free radial forearm flap phalloplasties, 232 free radial forearm flap phalloplasties were performed after Gottlieb and Levine in 229 patients. Operation and patient-specific characteristics were evaluated. RESULTS: This study presents the highest number of free radial forearm flap phalloplasties after Gottlieb and Levine. The rate of total flap failure was 3%; 46% of the patients were heavy smokers. Urinary fistulae and strictures are common. The revision rate for urinary fistulae and/or strictures was 1.3 per patient. The number of postoperative complications, such as bleeding (14.2%), thrombosis of the flap requiring revision (11.2%), or delayed wound healing (16.8%) was considering the high rate of nicotine abuse (45.9%) reasonable. CONCLUSION: The free radial forearm phalloplasty in the design by Gottlieb and Levine is well established at our institution and has proven safe and reliable since 1993. The operative results are satisfactory for both patients and surgeons even in the presence of relevant comorbidities and heavy smoking. We acknowledge the long ordeal and psychological pressure that our patients suffer from, before presenting in our outpatient clinic.

RESUMEN

Blepharoplasty is the third most common plastic surgical procedure in the USA. Due to the emergence of multiresistant bacteria, optimising the antiseptic procedure is crucial. Choice of antiseptics plays an important role as they may cause skin irritation and colouring of disinfected areas. In this study, the use of the aqueous antiseptic octenisept® (octenidine) was evaluated in the outcome of blepharoplasties: incidence of wound dehiscence; haematoma; and infection in correlation with gender, medication, smoking habits and time of year. This retrospective surveillance study included 352 patients (median age 58·3 years). Skin disinfection was performed thrice prior to blepharoplasty. Sutures were removed on day 6. None of the patients suffered from wound infection. The total rate of wound dehiscence was 6·3%, with a higher ratio among male patients. Smokers and patients on anticoagulant medication showed a significantly higher incidence of wound dehiscence. Throughout the year, rates of wound dehiscence were highest in summer. Aseptic surgical preparation for blepharoplasty via full-face scrub with octenisept® without oral antibiotic prophylaxis is well tolerated, with no report of wound infection, which may improve antibiotic stewardship as well as patient comfort. Elective upper eyelid blepharoplasty may ideally be performed in winter.

RESUMEN

OBJECTIVES: Postoperative pain management is of highest interest for patients undergoing maxillofacial surgery including microvascular reconstructive surgery. Currently, there is a lack of information regarding process and outcome of postoperative pain management after microvascular reconstruction. MATERIALS AND METHODS: In a prospective clinical study, 31 adults were evaluated on the first postoperative day following microvascular reconstruction with a radial forearm flap using the standardized questionnaire of the Germany-wide project Quality Improvement in Postoperative Pain Management (QUIPS). It enables a standardized assessment of patients' characteristics, pain parameters, outcome and pain therapy process parameters. RESULTS: Pain management consisted predominately of premedication with midazolam, sufentanil and metamizol intraoperatively, piritramid in the intensive care unit and metamizol, tramadol and fentanyl patches on ward. Nineteen patients (61.3 %) showed inadequate pain management with pain levels ≥4. Among other significant relations, patients exhibiting an age below the median presented significant higher levels of pain under strain (p = .041) and maximum pain (p = .006) as well as rate of breathing (p = .009) and mood (p = .006) disturbance. Performance of pain counselling showed specific impact on pain under strain (p = .008), maximum pain (p = .004) and satisfaction with pain intensity (p = .001). Whether microvascular reconstruction was performed with primary or secondary intention or performance of a neck dissection did not show significant influence. CONCLUSIONS: QUIPS helped us to adequately evaluate the procedure-specific quality of postoperative management following microvascular reconstruction with a radial forearm flap. It helped us to identify a surprisingly high amount of inadequate pain management. Postoperative pain levels seem to be primarily influenced by the performed reconstruction. CLINICAL RELEVANCE: Establishment of a continuous and procedure-specific evaluation of postoperative pain levels should help to avoid inadequate pain management, which is widely prevalent according to the literature and our study. Preoperative pain counselling is essential and should be procedure specific to be its best.

RESUMEN

Capnocytophaga canimorsus is a bacterium transmitted through the saliva of dogs. An infection can cause severe sepsis with acral necrosis and is potentially fatal. Here, we report the case of a 41-year-old man who was infected through a wound that was licked by his dog. He went into septic shock with disseminated intravascular coagulation and subsequently lost both lower legs, his nose and all the fingers on both hands.

RESUMEN

Pressure sore rates remain high in both nursing homes as well as in hospitals. Numerous surgical options are available for defect coverage in the sacral region. However, objective data is scarce as to whether a specific flap design is superior to another. Here, we aim to compare two fasciocutaneous flap designs for sacral defect coverage: the gluteal rotation flap and the gluteal V-Y flap. All primary sacral pressure sores of grades III-IV that were being covered with gluteal fasciocutaneous rotational or V-Y flaps between January 2008 and December 2014 at our institution were analysed. A total of 41 patients received a total of 52 flaps. Of these, 18 patients received 20 gluteal rotational flaps, and 23 patients received 32 V-Y flaps. Both groups were comparable with regards to demographics, comorbidities and complications. Significantly more V-Y flaps were needed to cover smaller defects. Mean length of hospital stay was significantly prolonged when surgical revision had to be carried out. Both flap designs have proven safe and reliable for defect coverage after sacral pressure sores. Gluteal rotational flaps appear to be more useful for larger defects. Both flap designs facilitate their reuse in case of pressure sore recurrence. Complication rates appear to be comparable in both designs and to the current literature.

RESUMEN

The development of pressure sores is still not only an enormous economical but also a medical burden. Especially in the ischial region, the local defect coverage remains demanding as it is the main weight-bearing area in wheelchair-mobilised patients and is prone to high mobility. The purpose of our study was to report our long-time experience with the reconstruction of ischial pressure ulcers with the medially based posterior thigh flap. A retrospective analysis of all primary pressure sores grade III-IV in the ischial area, which were covered with a medially based posterior thigh flap between January 2008 and December 2014, at our department was conducted. A total of 28 patients underwent defect coverage of an ischial pressure sore with the aforementioned flap. The subgroup with complications showed a statistically significant longer hospital stay. A statistically significant correlation between age and the coincidence of comorbidities could be seen. Older patients showed significantly higher grades of pressure sores. The medially based posterior thigh flap is a safe and reliable flap design. Complication rates are comparable to other flaps. Nevertheless, in case of complications, a significantly longer duration of hospitalisation has to be taken into account.

RESUMEN

Soft tissue defects in the genito-perineal region are predominantly because of trauma, infections, neoplasms or iatrogenic causes. As a result of the region's urological, reproductive and gastrointestinal function, defects in this area may cause devastating physical and psychological consequences as well as diminished sexual functioning. The purpose of this study was to examine the efficacy of implementing a medial thigh lift for defect coverage in the perineal region. A retrospective analysis of all medial thigh lift procedures for defect coverage in the genito-perineal region between November 2010 and March 2015 was conducted at three institutions. Ten consecutive patients underwent a medial thigh lift for defect coverage in the genito-perineal region. Nine patients were male, and one was female. The causative factors were Fournier's gangrene in eight patients, one patient had a straddle injury, and one suffered from extramammary Paget's disease. The mean follow-up time was 19·8 months. The average total defect size was 11·1 × 11 cm (length × width). The medial thigh lift procedure is a safe, technically easy and reliable technique with discrete scars. Outstanding aesthetic and functional outcomes result in a high rate of patient satisfaction. Through immediate wound closure, a reduction of recovery time can be achieved.

RESUMEN

BACKGROUND: The influence of orbital fractures and their repair on the rate of deformities of the lower eyelid is an ongoing source of discussion in the literature. Most of the present studies include isolated blow-out as well as combined orbital fractures. MATERIAL AND METHODS: We present a retrospective evaluation of a series of 100 patients after isolated blow-out fracture repair using reference anthropometric data on standardized photographs. Analysis included eye fissure width and height, lid sulcus height, upper lid height, upper and lower iris coverage, position of cornea to palpebra inferior, canthal tilt, scleral show, ectropion and entropion. It was clearly distinguished between operated and contralateral eyelid, whether a transconjunctival or a subciliary approach was performed and amount of fracture. Our main interests were changes of the aforementioned parameters with regards to eyelid deformities. RESULTS: Surgery per se did not significantly influence eyelid deformities. However, the surgical approach selected significantly affected eye fissure index, lower iris coverage and rate of scleral show, indicating retraction of the lower eyelid. CONCLUSIONS: The standardized measurements described here are accurate and objective to evaluate postoperative results. The subciliary approach included the highest risk of lower lid retraction as compared to transconjunctival approaches.

RESUMEN

OBJECTIVES: There is a lack of literature regarding the procedure-specific quality of acute postoperative pain management after midfacial fracture repair. The purpose of the presented prospective clinical study was to evaluate postoperative pain management after surgical repair of midfacial fractures. MATERIALS AND METHODS: Eighty-five adults were evaluated on the first postoperative day following midfacial repair using the questionnaire of the Quality Improvement in Postoperative Pain Management (QUIPS) project. The main outcome measures were patients' characteristics and clinical- and patient-reported outcome parameters. RESULTS: Overall, pain on the first postoperative day was moderate. A significant correlation between process and outcome parameters could be shown. Duration of surgery above the calculated median was significantly associated with higher maximum pain intensity (p = 0.017). Patients requiring opioids in the recovery room presented significantly higher pain on activity (p = 0.029) and maximum pain (p = 0.035). Sleeping impairment (p = 0.001) and mood disturbance (p = 0.008) were significantly more prevalent in patients undergoing repair of a centrolateral midfacial fracture. CONCLUSIONS: QUIPS is a simple and qualified tool to evaluate the procedure specific quality of acute postoperative pain management. Pain on the first postoperative day following midfacial fracture repair seems overall to be moderate. Nearly a third of the patients showed inadequate postoperative pain management. To prevent inadequate postoperative pain management, it is necessary to establish a continued procedure-specific outcome measurement.

RESUMEN

OBJECTIVES: To adequately perform orthognathic surgery procedures, it is from basic interest to understand the morphologic changes caused by orthognathic surgery. Anthropometric analyses of standardized frontal view and profile photographs could help to investigate and understand such changes. STUDY DESIGN: We present a pre- to postoperative evaluation of orthognathic surgery results based on anthropometric indices described by Farkas and cephalometric measurements. 30 Class III patients undergoing maxillary advancement by Le Fort I Osteotomy and mandibular setback by bilateral sagittal split osteotomy were evaluated. Preoperative as well as three and nine months postoperative lateral cephalograms as well as standardized frontal view and profile photographs were taken. On the photographs 21 anthropometric indices given by Farkas were evaluated. In cephalograms SNA and SNB angle as well as Wits appraisal were investigated. RESULTS: The investigated anthropometric indices showed a significant increase of the vertical height of the upper lip without changing the relation of the upper vermilion to the cutaneous upper lip. The lower vermilion height increased relatively to the cutaneous lower lip without vertical changes in the lower lip. Due to maxillary advancement the upper face height increased meanwhile the lower face height decreased due to mandibular setback. SNA and SNB angle and Wits appraisal showed typical changes related to surgery. CONCLUSIONS: The investigated photo-assisted anthropometric measurements presented reproducible results related to bimaxillary surgery.

RESUMEN

Skin dendritic cells (DC) express C-type lectin receptors for the recognition of pathogens. Langerhans cells (LC) express the receptor Langerin/CD207, whereas DEC-205/CD205 is mainly expressed by dermal DC, but can also be detected at low levels on LC. In this study, we tested an ex vivo approach for targeting DC in situ with monoclonal antibodies (mAb) against Langerin and DEC-205. The targeting mAb was injected intradermally into human skin biopsies or added to the medium during skin explant culture. Corresponding to the expression patterns of these lectin receptors on skin DC, Langerin mAb was detected merely in LC in the epidermis and DEC-205 mainly in dermal DC in human skin explants, regardless of the application route. Migratory skin DC bound and carried targeting mAb from skin explants according to their lectin receptor expression profiles. In contrast to the very selective transport of Langerin mAb by LC, DEC-205 mAb was more widely distributed on all CD1a(+) skin DC subsets but almost absent in CD14(+) dermal DC. As effective vaccination requires the addition of adjuvant, we co-administered the toll-like receptor (TLR)-3 ligand poly I:C with the mAb. This adjuvant enhanced binding of DEC-205 mAb to all skin DC subsets, whereas Langerin targeting efficacy remained unchanged. Our findings demonstrate that LC can be preferentially targeted by Langerin mAb. In contrast, DEC-205 mAb can be bound by all CD1a(+) skin DC subsets. The efficacy of DEC-205 mAb targeting strategy can be boosted by addition of poly I:C underlining the potential of this combination for immunotherapeutical interventions.

RESUMEN

UNLABELLED: This retrospective study aimed to evaluate how reduction mammaplasty influences the bodyweight of patients 5 years after the procedure. The literature shows controversy regarding the effect of breast reduction on the progression of bodyweight. Between 1 January 2006 and 31 July 2007, 249 reduction mammaplasties were performed in the Department of Plastic, Reconstructive, and Aesthetic Surgery at the University Hospital Innsbruck. The exclusion criteria ruled out patients with oncoplastic breast reduction plasties, unilateral reduction mammaplasty, no documented preoperative weight, and bariatric procedures. The study finally included 50 women with a mean age of 44 ± 12 years. Of these 50 women, 26 (52 %) gained weight, 18 (36 %) lost weight, and 6 (12 %) remained stable during a 5-year follow-up period after the procedure. The mean weight gain was 4.50 ± 3.5 kg, and the mean weight loss was 3.44 ± 2.20 kg. The results of the study suggest that reduction mammaplasty is not a stimulus for weight loss. Although a tendency to gain weight was discovered, the weight gain compared with that of the standard population did not reach statistical significance.

RESUMEN

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Despite diverse anatomical and histological trials in humans and animal models, the aetiology of hypospadias remains unknown and currently there is no clear molecular explanation about the emergence of this disease; however, genetic, endocrine and environmental mechanisms have been suggested. The aim of the present study was to quantify and compare the androgen receptor (AR; mRNA and protein) levels in 40 prepuces of boys with and without hypospadias using quantitative real-time polymerase chain reaction, Western Blot and standardised, automated immunohistochemistry. AR mRNA (P = 0.013) and AR protein (P = 0.014) was significantly elevated in the prepuces of boys with hypospadias compared with boys without hypospadias. Altogether our data indicate that elevated AR mRNA and protein levels can be considered as a biochemical response of an AR signalling defect as an identified cause in boys with hypospadias. Additionally, nuclear staining intensity for AR-protein in specimens of boys with hypospadias was higher than in boys with phimosis. OBJECTIVE: To address the role of the androgen receptor (AR) on mRNA and protein levels in prepuces of boys with and without hypospadias. PATIENTS AND METHODS: Data from 40 foreskin specimens of consecutive circumcised boys (20 with vs 20 without hypospadias) were enrolled in this prospective study. After surgery, samples were fixed in formaldehyde and frozen in liquid nitrogen. Total RNA was isolated from frozen tissue and transcribed to complementary DNA. The amount of AR mRNA was measured by quantitative real-time polymerase chain reaction and Western Blot and standardised, automated immunohistochemistry were used to assess AR protein levels. RESULTS: The mean age at time of surgery was 61.8 and 30.9 months in boys without and with hypospadias, respectively. There was penile, coronal and sine hypospadias in seven (35%), nine (45%), and four (20%) boys, respectively. AR mRNA was significantly elevated in the prepuces of boys with hypospadias compared with boys without hypospadias, at a mean (sd) of 28.33 (5.39) vs 15.31 (1.85) (P = 0.013). Furthermore, the amount of AR protein was higher in boys with, compared with boys without hypospadias, at a mean (sd) of 133.25 (6.17) vs 100 (4.45) (P = 0.014). CONCLUSIONS: Different AR mRNA expression and protein levels seem to be an indication of an AR signalling defect as a cause in boys with hypospadias. Decreased AR DNA binding and functional capability may result in a compensatory up-regulation of both AR mRNA and protein. Further studies are necessary to perform structural analysis of the AR and to corroborate these preliminary findings.

RESUMEN

(1) Background: Postoperative pain is a frequently underestimated complication significantly influencing surgical outcome and patient satisfaction. While abdominoplasty is one of the most commonly performed plastic surgery procedures, studies investigating postoperative pain are limited in current literature. (2) Methods: In this prospective study, 55 subjects who underwent horizontal abdominoplasty were included. Pain assessment was performed by using the standardized questionnaire of the Benchmark Quality Assurance in Postoperative Pain Management (QUIPS). Surgical, process and outcome parameters were then used for subgroup analysis. (3) Results: We found a significantly decreased minimal pain level in patients with high resection weight compared to the low resection weight group (p = 0.01 *). Additionally, Spearman correlation shows significant negative correlation between resection weight and the parameter "Minimal pain since surgery" (rs = -0.332; p = 0.013). Furthermore, average mood is impaired in the low weight resection group, indicating a statistical tendency (p = 0.06 and a Χ2 = 3.56). We found statistically significant higher maximum reported pain scores (rs = 0.271; p = 0.045) in elderly patients. Patients with shorter surgery showed a statistically significant (Χ2 = 4.61, p = 0.03) increased claim for painkillers. Moreover, "mood impairment after surgery" shows a dramatic trend to be enhanced in the group with shorter OP duration (Χ2 = 3.56, p = 0.06). (4) Conclusions: While QUIPS has proven to be a useful tool for the evaluation of postoperative pain therapy after abdominoplasty, only continuous re-evaluation of pain therapy is a prerequisite for constant improvement of postoperative pain management and may be the first approach to develop a procedure-specific pain guideline for abdominoplasty. Despite a high satisfaction score, we detected a subpopulation with inadequate pain management in elderly patients, patients with low resection weight and a short duration of surgery.

RESUMEN

The ever-expanding number of transmen as well as their surgeons share an increasing interest in the construction of a neophallus. While the indication for surgery and the positive effect of a phalloplasty on the quality of life, mental health and sexual function has already been thoroughly analysed, there is a lack of data comparing and evaluating the surgical steps. During the consensus conference on the "choice of flaps for phalloplasty" at the annual meeting of the German-Speaking Society for Microsurgery of Peripheral Nerves and Vessels, the current literature was discussed and a consensus on the surgical technique of a phalloplasty was reached. This manuscript publishes jointly developed recommendations on the following topics: choice of flaps for phalloplasty, preoperative diagnostic tests before phalloplasty, urethral construction in the radial forearm flap and anterior lateral thigh flap, preformation of the urethra at the forearm or thigh, venous drainage of the radial forearm flap, innervation of the phallus, staged phalloplasty, coronaplasty and managing the donor site of a radial forearm flap.

RESUMEN

BACKGROUND: Reconstructed mechanically stressed zones of the lower extremity frequently suffer from problems such as hyperkeratotic edges or chronic ulcerations in the transition zone between conventional thigh skin grafts and normal skin. Defect coverage with skin grafts harvested from the instep region and placed on muscle flaps is not yet an established alternative. METHODS: This is a retrospective study of a series of 12 clinical applications of soft tissue reconstruction at mechanically exposed zones of the lower extremity. Locally transposed or transplanted muscle flaps were covered with meshed instep skin instead of meshed thigh skin for the purpose to gain a superior stable skin surface and transition zones adjacent to normal skin. RESULTS: There is no ulceration found at follow-up from 6 to 72 months. Only one case presented with delayed graft take. Different thicknesses of the corneal layers of the healed instep versus thigh skin grafts were verified histologically. Instep skin grafts showed substantial durability as well as advantageous aesthetic appearance with respect to texture and coloring. All donor sites healed without notable scars or sensitivity disorders. CONCLUSIONS: The instep split skin graft is particularly well suited for defect coverage of muscle flaps transposed or transplanted to mechanically stressed zones of the foot or lower leg. The paramount advantage of transplanted instep skin as compared to thigh skin is given by the feasibility to create a durable graft with a thick horny layer and a stable transition zone at its periphery that is bordering normal skin.
