RESUMO
INTRODUCTION: Skin malignancy is one of the most common reasons for seeking out a plastic surgery clinic. This article presents an overview of the therapeutic results at Department of Plastic and Aesthetic Surgery Brno and includes an algorithm according to which we proceed in the treatment of patients with skin malignancy. MATERIAL AND METHODS: Retrospective analysis of data for the year 2022, including a set of 791 patients with a total of 1,117 procedures to remove skin malignancy. The representation of cutaneous malignancy was as fol-lows - basalioma (51%), squamous cell carcinoma (14%), and other malignancies including precancerous lesions were represented in 35%. Age, sex, a character and a number of procedures (excision, re-excision, controlled excision), and the histological results of resected specimens (with a sufficient margin or ingrowth) were evaluated. Based on the analysis of the patient cohort, an algorithm is presented to guide the surgical management of the patient. RESULTS: Patients' age ranged from 26 to 102 years. There was a discrete male predominance in the cohort (51%). Tumour localization was most frequently on the skin of the face, cleavage, and extremities. Regarding the spectrum of procedures, excision accounted for the largest proportion (83%). Re-excision accounted for the rest of the procedures (10%), controlled excision was performed in 6% and excisional bio-psy accounted for 1%. Primary sanative excision with a histologically sufficient margin was performed in 96%. In the group of controlled excisions, 59% were sanative. Overall, 73% of patients in our cohort underwent a single operation only to remove a cutaneous malignancy. CONCLUSION: The results of the therapy and the algorithm of the care for patients with skin malignancy can be evaluated as successful based on the analysis performed. The determination of the surgical strategy according to the algorithm appears to be effective. The authors recommend its use in practice, especially with the current trend of the increasing incidence of skin malignancies and the desire to improve the effectiveness of surgical interventions.

INTRODUCTION: The bilobed flap was first described by Esser in 1918. He used it to reconstruct the defects of the nose. It has been used in the reconstructions of trunk and feet defects by many authors since then. Its principle is also advantageous in reconstructions of larger facial defects. Successful reconstruction of problematic suborbital area using the bilobed flap was reported by Yenidunya in 2007. The design of the flap can be successfully used in other atypical facial defects. MATERIAL AND METHODS: The bilobed flap was used to cover facial defects of 199 patients who underwent 203 tissue reconstructions from 1st January 2007 to 31st December 2016 at the Department of Plastic and Aesthetic Surgery St. Anne´s University Hospital in Brno. RESULTS: The flaps were equally distributed between the genders, men 101 and women 98. Ages of patients ranged from 39 to 98 years (mean 76 years). It was used in the reconstruction of the tip and alars defects of the nose 159 times, in the reconstruction of periorbital defects 16 times and in other atypical facial areas 28 times. The excision of malignant tumours of the face (basal cell carcinoma, squamous cell carcinoma, SSM) were usually the causes of the defects (89.7%). There were 80 cases with defects of the nasal tip and ala in men and 79 cases in women. Complications occurred 41 times of all reconstructions (20.2%). The most common complication was abundance of the flap (4.9%). The postoperative results were favourable due to the preservation of colour, texture and function of the reconstructed areas. CONCLUSION: Bilobed flap in different modifications should always be considered in the reconstruction of extensive defects of the face, because unlike other techniques, it preserves good texture and colour of facial skin with minimal donor site morbidity.

The reconstruction of complex craniofacial and orbital defects should satisfactorily restore functional and aesthetic integrity. Autologous reconstruction of nasal, periorbital and auricular facial subunits as a whole using a locoregional or a free flap is very challenging and the results are not sometimes ideal. With advanced technologies that are currently available it is possible to plan and produce authentic facial prosthesis that can satisfactory substitute these facial subunits. We demonstrate an alternative reconstructive concept for complex craniofacial defects based on a free flap combined with a facial prosthesis for the replacement of periorbital or auricular facial subunits. This approach was used in two patients with very satisfactory results. Combination of a free flap with a facial prosthesis may become a preferable approach for the reconstruction of complex craniofacial defects. Clinical outcomes of the reconstructions may be enhanced respecting the principle of aesthetic facial subunits.

BACKGROUND: The effect of magnesium sulphate on mechanically provoked vasospasm of the flap pedicle on porcine model was not studied yet. Positive effect of magnesium sulphate on vasospasm was proved in previous studies on rat. METHODS: The bilateral pedicled flaps based on the caudal superficial epigastric arteries were raised on 8 pigs. Flaps on the right side were the treatment group; flaps on the left side were the control group. The vasospasm was provoked by the tension applied on the pedicle in the axial direction using 160g weight. The blood perfusion of the flap was monitored using laser-Doppler. The duration of the vasospasm was defined as the time from the release of the tension until the blood flow began to rise. These times were detected using an automated computerized detection. In the treatment group, magnesium sulphate was given topically on the vessel; saline was used in the control group. RESULTS: The duration of the vasospasm in the treatment group was significantly shorter than in the control group (P = 0.024). CONCLUSION: Magnesium sulphate 10% shortened significantly the mechanically provoked vasospasm on caudal superficial epigastric flap in a porcine model. Further clinical studies are needed to prove the effect in humans.

PURPOSE OF THE STUDY: Two tendons, i.e., the extensor indicis proprius (EIP) and the extensor carpi radialis longus (ECRL), are commonly used to reconstruct the function of a ruptured extensor pollicis longus (EPL) tendon. We reviewed a group of patients with EPL ruptures treated by ECRL tendon transfer to the EPL tendon, which was the method of choice. The aim was to evaluate the results and to assess the effect of ECRL detachment on hand function. MATERIAL AND METHODS: Twenty patients were treated surgically for a subcutaneous rupture of the EPL tendon between 2003 and 2007. Each patient was examined at 2 years after surgery. The range of motion (ROM) of both the injured and the contralateral hand was recorded and evaluated with a modified Geldmacher scoring system; a response to the DASH questionnaire was obtained. The mean follow-up was 24 months (19-31 months). RESULTS: For the ROM of the operated hand, the mean Total Active Motion (TAM) of 98.75 degrees (60-140, SD 22.74) was calculated. The mean extension lag at the interphalangeal (IP) joint was 5.42 degrees (0-25, SD 8.77) and the mean IP flexion was 65.8 degrees (40-80, SD 13.2). In order to evaluate body side differences, the ROM of the contralateral thumb was recorded. The values were as follows: mean TAM, 141.3 degrees (115-190, SD 20.43); mean IP extension lag, 0 degrees (0-0, SD 0); mean IP flexion, 68.8 degrees (50-80, SD 9.6). DISCUSSION: The extension lag at the IP joint was detected in both the operated and the contralateral hands. The patients examined at a longer interval after surgery showed an increase in extension lag. This may have been caused by undesired adaptation of the donor muscle, the presence of adhesions or suture loosening. CONCLUSIONS: The results showed increased adaptation of thumb motion to the extension lag at the IP joint, which had a mild effect on the patient's hand function. The difference in wrist extension between the operated and the contralateral hand corresponded to the pre-operative condition.

We present a group of 20 patients who underwent transposition of the extensor carpi radialis longus to the extensor pollicis longus between April 2003 and September 2007. The group was divided into ten patients with an early dynamic splint and ten patients with a static plaster cast following the standard rehabilitation protocols. We compared these two rehabilitation protocols. The post-rehabilitation total range of motion was 87.5 degrees in the dynamic group and 58.75 degrees in the patients treated by the static protocol. The total time of rehabilitation was 10.2 weeks in the dynamic and 14.2 weeks in the static group. The overall mean follow-up was 12.2 weeks. We conclude that early dynamic splinting brings shorter recovery time, shorter time off work and significantly better movement of the thumb.

Venous free flaps should be considered as potential reconstructive options for large dorsal digital defects with exposed bone, joint and/or extensor tendons, if local flaps are inadequate or unusable. We describe our experience of thirteen venous free flaps in twelve patients with large dorsal digital defects. Our survival rate for these flaps is comparable to the published data. The forearm donor site was closed primarily in all cases with minimal morbidity. The flaps should be monitored with Doppler devices as clinical evaluation is misleading secondary to the venous congestion inherent in these flaps. This reconstructive option has become a well-established procedure in our hands and is the alternate reconstructive method of choice for large dorsal digital defects where local flaps are not usable or inadequate due to complex hand injuries or multiple finger defects.

BACKGROUND: Unilateral breast reconstruction with a free abdominal TRAM or DIEP flap restores the shape of the amputated breast with acceptable donor site morbidity. In patients with small breasts and ample lower abdominal tissue this can be achieved by using only a hemi-abdominal flap. In these cases, the contra-lateral flap is usually discarded, but it could potentially be left in situ as a "spare" hemi-abdominal flap, especially in patients at high risk for contra-lateral breast cancer or flap failure. We report our early experience with this preservation technique. MATERIAL AND METHODS: The authors report two cases of unilateral breast reconstruction with hemi-abdominal DIEP free flaps in women at high risk for contra-lateral breast cancer and/or flap failure, who opted not to have prophylactic contra-lateral mastectomies. They consented to having the unused "spare" hemi-abdominal deepithelialized flap left in situ in case the need for a secondary flap arose. RESULTS: The "spare" hemi-abdominal flap was used for immediate reconstruction as an SIEA free flap when the first patient's original flap necrosed secondary to microcirculation problems. The second patient's spare flap was left in situ by burying it after de-epithelialization. CONCLUSIONS: We believe that patients undergoing unilateral breast reconstruction who are at high risk for contra-lateral breast cancer and/or free flap failure, and who choose not to undergo an immediate contra-lateral prophylactic mastectomy, should have the "spare" hemi-abdominal flap buried. This tissue could be used as a potential bailout flap in cases of original flap failure or for contralateral breast reconstruction at a later date.

Twenty two patients with gender dysphoria underwent neo-phalloplasties using a novel technique. Latissimus dorsi musculocutaneus re-innervated free flap was used to allow voluntary rigidity of the neo-penis. From the first 22 patients, 18 have obtained motoric function of reconstructed penis; the "paradox erection" was obtained. 14 patients came for examination after a follow-up period of mean 26.4 months. We evaluated the motility and shape changes of neo-phallus measuring its different size and dimension during relax and muscle contraction. The range of neo-phallus length in relaxed position was between 7 and 17 cm (mean 12.2 cm), its circumference in the same position had a range between 13 and 20 cm (mean 13.7 cm). All patients were able to contract the muscle with an average length reduction of 3.08 cm and an average circumference enlargement of 4 cm. In this study, the dimensions and motility were quantified demonstrating the neo-phallus function and size changes during sexual intercourse.

The authors used as a standard a one-stage method of microsurgical reconstruction of the penis, urethra and glans in 38 transsexual patients, a combination of Biemer's method, Trengove-Jones and Horton's suture of the glans. The reconstruction method is described in detail. Although reconstruction of the penis and urethra involved a group of 49 patients and accounted for less than 10% of all microsurgical tissue transfers in traumatology, oncological surgery and congenital defects, they are an important activity in systematic surgery.

One of the important microsurgical procedures in our department is breast reconstruction after ablations. For many years, the standard method was reconstruction with autologous tissues--a free TRAM flap with a recipient vessels vasa mammaria. We are convinced that this give very satisfactory results with microsurgical safety of operations. We use this method of reconstruction in 17-20 patients per year. The standard time of unilateral reconstruction is 2.5-4 hours, of bilateral reconstruction 4-6 hours. Postoperative morbidity in the abdominal region is, as a rule, associated with a weakening of the abdominal wall and the development of hemias (Galli et al., 1992); a perforator flap in which neither muscle nor fasciae are used creates the prerequisite condition for markedly reduced the morbidity associated with the site of flap collection. Although we used a perforator flap three times for reconstructions of the extremities as early as three years ago, we began to use it for breast reconstruction from the beginning of 2000. No doubt this late use of a large skin flap supplied by 1-2 perforators was due to a lack of trust in the provision of adequate blood perfusion for the large amount of tissue of the flap. From the beginning of 2000, in the course of five months, nine DIEP flaps were used for breast reconstructions, in two cases for bilateral reconstruction. In two instances sensory nerves of the flap were sutured to the branch of the intercostal nerves at the site of insertion. Seven flaps healed p.p.i; in two instances we were faced with the complication of postoperative venostasis, calling for revision and connection of the superficial venous system of the flap to the circulation. Subsequent healing was without complications. Preparation of the flap appears to be relatively easy, and the only pitfall is the selection of a suitable perforator. The operation is longer by half an hour than the classical free TRAM; when the sensory nerve of the flap is sutured, it is ca 1 hour longer. We like to use the DIEP flap for breast reconstruction, and it is a reliable method even for the reconstruction of large pendulous breasts. The donor site morbidity is significantly lower.

Replantation surgery is a specialization in plastic surgery which, in comparison with other disciplines, has a relatively short history of only forty years. Replantation surgery developed due to experience with macrovascular anastomosis and to the evolution of the operative microscope, special micro-instruments and ultra delicate suturing material. Due to these advances, it is possible to implement anastomosis of blood vessels with a diameter smaller than 1-2 mm. Each of the three pillars of microvascular surgery has its own history. This work outlines their use and the contribution of each to the development of microsurgery. Finally, it compares the development of replantation surgery in the Czech Republic and worldwide within a specific time frame.

BACKGROUND: In our preliminary experiments we found that composite skin grafts consisting of allogeneic acellular dermis and thin epidermal autologous grafts applied to the excised burn wound in one stage led to better results in terms of viscoelastic properties than autologous split-thickness skin grafts. PATIENTS AND METHODS: In ten burn patients we applied composite skin grafts consisting of allogeneic acellular dermis and thin epidermal autologous grafts and followed the quality of the reconstructed skin cover with a special device, Cutometer MPA 580, over a period of four years. RESULTS: The cutometric curves demonstrated better viscoelastic properties in composite skin grafts than in conventional split-thickness skin grafts after four years. We found Cutometer MPA 580 to be an advantageous device for the objectification of improved quality of reconstructed skin cover. DISCUSSION: Among the various methods the cutometer showed the advantage of being a non-invasive, precise, and objective method of measuring skin's viscoelastic properties. The Vancouver Scar Score is a subjective evaluation of skin viscoelasticity. CONCLUSION: Our prospective clinical study clearly demonstrated that cutometric measurement produced objective results in contrast to clinical evaluation, the Vancouver Scar Score, and other non-quantitative methods. Our hypothesis that composite skin grafts consisting of allogeneic acellular dermis and thin epidermal autologous grafts applied onto the excised burn wound in one stage led to better results in terms of viscoelastic properties than autologous split-thickness skin grafts was fully confirmed.
