RESUMO

BACKGROUND: We focused on the therapeutic effects of the stable gastric pentadecapeptide BPC 157 in spinal cord injury using a rat model. BPC 157, of which the LD1 has not been achieved, has been implemented as an anti-ulcer peptide in inflammatory bowel disease trials and recently in a multiple sclerosis trial. In animals, BPC 157 has an anti-inflammatory effect and therapeutic effects in functional recovery and the rescue of somatosensory neurons in the sciatic nerve after transection, upon brain injury after concussive trauma, and in severe encephalopathies. Additionally, BPC 157 affects various molecular pathways. METHODS: Therefore, BPC 157 therapy was administered by a one-time intraperitoneal injection (BPC 157 (200 or 2 µg/kg) or 0.9% NaCl (5 ml/kg)) 10 min after injury. The injury procedure involved laminectomy (level L2-L3) and a 60-s compression (neurosurgical piston (60-66 g) of the exposed dural sac of the sacrocaudal spinal cord). Assessments were performed at 1, 4, 7, 15, 30, 90, 180, and 360 days after injury. RESULTS: All of the injured rats that received BPC 157 exhibited consistent clinical improvement, increasingly better motor function of the tail, no autotomy, and resolved spasticity by day 15. BPC 157 application largely counteracted changes at the microscopic level, including the formation of vacuoles and the loss of axons in the white matter, the formation of edema and the loss of motoneurons in the gray matter, and a decreased number of large myelinated axons in the rat caudal nerve from day 7. EMG recordings showed a markedly lower motor unit potential in the tail muscle. CONCLUSION: Axonal and neuronal necrosis, demyelination, and cyst formation were counteracted. The functional rescue provided by BPC 157 after spinal cord injury implies that BPC 157 therapy can impact all stages of the secondary injury phase.

RESUMO

INTRODUCTION: Tibial plateau fractures are articular injuries that may influence final functional outcome of the knee. Although these fractures comprise only 1% of all fractures, the fracture pattern is usually complex and requires anatomical reduction and absolutely stable fixation to achieve satisfactory results. The development of knee osteoarthritis is a common late complication and it can be strongly influenced by additional, underestimated cartilage defects, and meniscal and ligament tears. MATERIALS AND METHODS: Between January 2012 and February 2015, a total of 78 patients with tibial plateau fractures (Schatzker type I-III) were enrolled in the study. Patients were divided into two groups: one group was treated with arthroscopically-assisted reduction and internal fixation (ARIF) and the other with open reduction and internal fixation (ORIF). The final number of patients was 75; 40 in the ARIF group and 35 in the ORIF group. Radiography and computed tomography were used to assess fracture pattern. An immediate postoperative radiograph was performed, and then repeated at 6 weeks, and 3,6 and 12 months after surgery. Demographic data (age and sex), additional intraarticular injuries, hospital stay and complications were noted, and clinical and radiological Rasmunssen score at 3, 6 and 12 months after surgery were evaluated. RESULTS: Additional intraarticular lesions were found in 27 patients; 20 in the ARIF group and 7 in the ORIF group (p = 0.06). There was a statistically significant difference in average duration of hospital stay: 3.10 ± 0.63 days for the ARIF group and 5.51 ± 1.66 days for the ORIF group (p = 0.0001). All fractures healed within 3 months following surgery. The overall complication rate was 12%. There was no statistically significant difference in complication rate between the two groups (p = 0.63). Clinical and radiological scores were excellent in most patients in both groups. There was no statistically significant difference in average clinical and radiological Rasmunssen scores between the two groups. CONCLUSIONS: Both ARIF and ORIF can provide equally good results; however, ARIF seems to offer a more precise evaluation and treatment of associated intraarticular lesions and to reduce the duration of hospital stay.

RESUMO

INTRODUCTION: The aim of this study was to compare reduction quality and functional outcome of posterior malleolus fractures treated with indirect reduction and anteroposterior (AP) fixation or with direct reduction via a posterolateral approach and posteroanterior (PA) fixation. METHODS: Forty-eight patients with trimalleolar fracture were enrolled in the study. Patients were randomised in two groups: indirect reduction and AP fixation (AP group) and direct reduction and PA fixation (PA group). Inclusion criteria were: posterior fragment involving more than 25% of the articular surface, displacement over 2mm and ankle instability. The quality of reduction was evaluated using postoperative plain radiographs. Residual displacement of the posterior fragment, articular step-off and/or articular surface gap were analysed. The reduction was considered excellent (<1mm), good (1-2mm) or poor (>2mm). Range of motion (ROM) was measured bilaterally, and the difference in dorsiflexion between the injured and uninjured side was considered as dorsiflexion restriction. Demographic data (age, sex), type of fracture (AO/ASIF classification) and complications were noted. RESULTS: Forty-six patients completed all follow-up examinations. There was no statistically significant difference in age (p = 0.41), sex (p = 0.29) or specific type of fracture (p = 0.83) distribution between the AP and PA groups. All fractures completely healed within 3 months. The overall complication rate was 8.7%. There was no statistically significant difference in complication rate between the two groups (p = 0.71). Radiological evaluation of the ankle showed there was significantly better quality of reduction with direct reduction via a posterolateral approach in the PA group. Excellent reduction was achieved in 79.2% and 45.5% of the PA and AP groups, respectively. The quality of reduction was significantly higher in the PA group compared with the AP group (p = 0.04). The mean restriction of dorsiflexion was lower in the PA group (5.96 ± 0.65°) compared with the AP group (6.45 ± 1.06°), but this difference did not reach statistical significance (p = 0.07). CONCLUSIONS: The direct reduction technique via a posterolateral approach and PA fixation enables higher quality of reduction and better functional outcome in the management of the posterior fragment compared with indirect reduction and percutaneous AP fixation.

RESUMO

INTRODUCTION: Distal tibial or pilon fractures are usually the result of combined compressive and shear forces, and may result in instability of the metaphysis, with or without articular depression, and injury to the soft tissue. The complexity of injury, lack of muscle cover and poor vascularity make these fractures difficult to treat. Surgical treatment of distal tibial fractures includes several options: external fixation, IM nailing, ORIF and minimally-invasive plate osteosynthesis (MIPO). Management of distal tibial fractures with MIPO enables preservation of soft tissue and remaining blood supply. This is a report of a series of prospectively studied closed distal tibial and pilon fractures treated with MIPO. MATERIALS AND METHODS: A total of 21 patients with closed distal tibial or pilon fractures were enrolled in the study between March 2008 and November 2013 and completed follow-up. Demographic characteristics, mechanism of injury, time required for union, ankle range of motion and complications were recorded. Fractures were classified according to the AO/OTA classification. Nineteen patients were initially managed with an ankle-spanning external fixator. When the status of the soft tissue had improved and swelling had subsided enough, a definitive internal fixation with MIPO was performed. Patients were invited for follow-up examinations at 3 and 6 weeks and then at intervals of 6 to 8 weeks until 12 months. RESULTS: Mean age of the patients was 40.1 years (range 19-67 years). Eighteen cases were the result of high-energy trauma and three were the result of low-energy trauma. According to the AO/OTA classification there were extraarticular and intraarticular fractures, but only simple articular patterns without depression or comminution. The average time for fracture union was 19.7 weeks (range 12-38 weeks). Mean range of motion was 10° of dorsiflexion (range 5-15°) and 28.3° of plantar flexion (range 20-35°). Three cases were metalwork-related complications. Two patients underwent plate removal at 24 weeks because of plate impingement. There was one case of wound breakdown at 11 weeks. One patient had fracture union with tibial recurvatum of approximately 10°, without functional impairment. Two patients had delayed union. CONCLUSION: MIPO is a reliable method of treatment for distal tibial fractures; it provides a high union rate and good functional outcome with minimal soft tissue complications. Skin impingement remains a common complication with MIPO, but this can be solved by timely plate removal.

RESUMO

The paper presents a modified operative technique for involutional lower lid entropion. The prospective noncomparative study of 101 lower eyelids of 88 patients undergoing surgery for involutional lower lid entropion was conducted in period from September 2005 until March 2012. Indication for the surgery was entropion, previously untreated, with moderate to severe horizontal lid laxity and no clinically relevant medial and lateral canthal tendon laxity. The operative technique is our modification of Quickert and Jones procedures. Photo was taken preoperatively and one month after surgery. Clinical follow-up was at 7th postoperative day, one month and six months after surgery and in case of the recurrence. Long-term follow-up was obtained via telephone interviews. There were 44 male (50%) and 44 female (50%) patients included in the study. The age of patients was in average 73.27 +/- 8.1 years (range 53-90 years). Early postoperative complication was localized lid swelling found in two patients starting 4-6 weeks postoperatively at the area of absorbable suture. It resolved spontaneously in two and three weeks respectively. There was recurrence of entropion in 11 eyelids (10.89%) of 10 patients. The mean interval between primary surgery and the recurrence was 17.45 +/- 14.84 months (range 4-48 months). In these eyelids Jones procedure was performed. However in four eyelids of four patients from the recurrent group an additional surgery needed to be performed after 6, 12, 12 and 17 months respectively. Our modification of surgical treatment for involutional lower lid entropion was effective in 89.11% of eyelids. Complications of the procedure were scarce.

RESUMO

PURPOSE: To present our experience with dermofat graft in reconstruction of anophthalmic socket. MATERIAL AND METHODS: In period from September 2005 until June 2009, eight patients have undergone orbital surgery of transplantation of dermofat graft. In six patients the dermofat graft was used as the secondary orbital implant after extrusion of hydroxyapatite orbital implant with major defect of bulbar conjunctiva. The other indication for the dermofat graft was correction of deep superior sulcus of the upper lid in anophthalmic socket in two patients. The graft was harvested from the left side of the belly. The size of the graft purposely exceeded the size of the defect to account for the expected tissue resorption. RESULTS: We experienced no major complication. Approximately 20-40% of dermofat graft reduction was noticed in 3-months period postoperatively. It took 6-8 weeks for the graft to fully epithelize from the conjunctival edge. Silicone conformer was introduced for that period of time. Subsequently, in two out of six patients with dermofat graft as the secondary implant, fornix had to be reconstructed later on with oral mucosa graft. CONCLUSION: Dermofat graft is a valuable material in orbital reconstruction especially in anophthalmic socket.

RESUMO

The incidence of fifth metatarsal fracture is somewhat common in sports and can be complicated in nature. Fractures of the fifth metatarsal can occur at a number of locations. Although some of these fractures respond well to conservative treatment, others have been notoriously hard to heal, with high rates of nonunions and other complications. Foot orthotic devices are commonly used as aids in the treatment of foot problems. In our case, we considered the combined effect of the surgical treatment and application of the custom-made foot orthoses. Special attention was taken with adjustments to the orthotic devices along and beneath the affected regions of the foot for adequate pain management and quick recovery to return to normal sports activities. Requirements for computer aided design/computer aided manufacturing orthotic design and manufacturing in this case were specific and considerably different from the usual procedure.

RESUMO

Cervical spondylosis is common condition rarely associated with radiculomyelopathy which surgical treatment, according to meta-analysis, is not better than nonsurgical. Our hypothesis was that neurodecompression which type is chosen according to spinal alignment should result in better functional improvement comparing with nonsurgical treatment. Between January 1, 1998 and December 31, 2007 a total of 77 patients with spondylogenic myelopathy were selected for the study. The inclusion criteria were symptoms and signs of myelopathy Ranawat grade III. Exclusion criteria were amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS). The curvature of the cervical spine was determined by Ishihara index. Anterior corpectomies and fusion was performed in the kyphotic spines, laminectomy with fusion in patients with neutral position, and open door laminoplasty in lordotic spines. Clinical improvement was assessed as differences between preoperative and 1-year follow up Nurick, modified Japanese Orthopedic Association (mJOA) myelopathy scales and walking test. Preoperative and postoperative transverse cord area and subarachnoid space were measured. Forty-four male and 31 female patients were surgically treated. Two patients with electrophysiological signs of ALS were excluded. Preoperative and postoperative mean +/- SD mJOA index was 9.15 +/- 1 and 13.01 +/- 1.4 (p < 0.001), Nurick grading scale 3.05 +/- 0.7 and 1.8 +/- 0.6 (p < 0.001), walking time (sec) 64.4 +/- 3.2 and 46.2 +/- 3.3 (p < 0.001), and number of steps 69.7 +/- 4.4 and 57.6 +/- 2.8 (p < 0.001) respectively. Preoperative and postoperative transverse cord area (mean +/- SD, mm2) was 46.7 +/- 5.4 and 60.2 +/- 2.6 (p < 0.001), and subarachnoid space 48.0 +/- 4.9 and 68.8 +/- 8.5 (p < 0.001) respectively. Our results showed that surgical treatment is beneficial for patients with spondylogenic myelopathy.

RESUMO

The paper is a prospective study of 23 lids of 20 patients with upper lid aponeurotic ptosis operated using microincision technique in period 2005-2008. There were 7 males and 13 females. Age of the patients was 28-83 years (y), average 61 +/- 17 y, for female 63 +/- 13.4 y and for male 61 +/- 19 y. Inclusion criteria were: aponeurotic upper lid ptosis more than 2 mm, no other lid abnormalities, minimal dermatochalasis, no previous or concomitant lid surgery. The procedure was performed in local anesthesia through 10 mm cut. Aponeurosis was fixated to the tarsal plate with two sutures. Success was considered if operated lid height differed up to 0.5 mm of the other eye and margin-to-reflex distance was 2-4 mm in primary position. Postoperative results regarding contour, skin crease and lash position were good in all patients. Regarding height, 19/23 (83%) met criteria of 0.5 mm of the other eye and MRD 2-4 mm. In one bilateral procedure there was an asymmetry of 1 mm. Three patients with unilateral procedure had at least 1mm asymmetry comparing to the other eye. Reoperation was neccessary in two bilateral cases. Lid fold was symmetrical only in 7 patients (35%). The rest had slight to grose lid fold asymmetry. Complications were scarce, in early postoperative period there was hematoma in two patients lasting up to three weeks. Late failure was noticed in two cases 6 and 8 months postoperatively. Advantages are: less anesthetic results in less decreased levator function and more accurate assessment of eyelid position intraoperatively, less distortion of the lid due to less bleeding and edema, shorter operation time, less scarring and shortened recovery time. However it can be used only in selective cases.

RESUMO

Aim of our paper is to present a case of painless Acanthamoeba keratitis in a soft contact lens wearer. A 17-year-old male, highly myopic, prolonged soft contact lens wearer, presented to us with painless red watery right eye having remarkably diminished vision. Last six weeks he was treated elsewhere for the microbial keratitis with no improvement. No pain was reported and on the direct questionnaire about it he denied it. There was marked mixed conjunctival and ciliary injection. A central stromal opacity with a pronounced surrounding corneal ring of inflammatory infiltration and epithelial defect was seen on biomicroscopy of the right eye. Circular pannus was already formed reaching epithelial defect overlying corneal ring infiltrate. Acanthamoeba spp in the corneal sample was confirmed. Prolonged therapy with 0.02% chlorhexidine digluconate solution combined with 0.1% hexamidine solution resulted in corneal healing left with a large central dense stromal opacity with circular pannus reaching peripheral third of the cornea but with very thin blood vessels and the best corrected visual acuity of 0.1 tested on Snellen chart. In conclusion, even in a lack of typical symptom for Acanthamoeba keratitis such as pain, this amoeba should be ruled out especially in a soft contact lens wearer.

RESUMO

Calcaneal fracture (CF) treatment results are not always satisfied. Our aim was to compare medium-term results between standardized and unstandardized protocol in treatment of displaced intra-articular CF. We evaluate experience of our Department where 50 patients with CF in last 5 years--Group X have been treated with standardized protocol, and compare their postoperative results with unstandardized treatment's effects in 50 patients with CF cured 5 years before--Group Y As based on Sanders classification, radiographic evaluation and Maryland Foot Score, postoperative results were satisfying in 100% X and 90% Y patients with intra-articular type I, in 86% X and 70% Y patients with type II, and sufficient in 75% X and 52% Y patients with type III, in 50% X and 33% Y patients with type IV. We suggest standardized protocol with operative treatment for types II, III and even for type IV of intra-articular CF.

RESUMO

The aim of the study was to supplement data on pelvic morphology and structural geometry. Using these data, a mathematical and biomechanical model was constructed. The research was divided into two parts. The first part comprised radiogrammetric analysis of pelvic morphology and geometry based on 60 AP x-rays of male and female pelvises. The spatial definition of the pelvis was given by three transverse and one sagittal diameter. Transverse diameters were measured at the level of iliac wings, at the narrowest supraacetabular portion and on the line passing through the center of both femoral heads. The fourth diameter was the height of the pelvis. Geometric properties and structure of pelvic bones and position of muscles in relation to bone elements of the pelvis were analyzed in the second part. Knowing geometric dimensions of the pelvis and the body weight, it is possible to calculate the magnitude of gravitational forces acting upon certain pelvic portions. This biomechanical model serves for simulation of operative methods of fixation and allows search for the optimal solution, which is stable enough to withstand all the forces acting upon fragments of a fractured pelvic ring.

RESUMO

CT was used in 50 adult pelvic fractures to determine the size and the position of relevant muscles with regard to bony elements in order to calculate muscle forces acting upon certain pelvic portions. Muscle length was measured to calculate muscle volume and physiological muscle cross-section. Among others, the size and direction of muscle forces were calculated for iliac, pubic and ischiadic fractures. The strongest muscle acting in iliac fractures is m. gluteus medius. The strongest upward pulling of iliac bone fragments is exerted by the erector muscles, while the major anterior, medial and downward pulling is performed by the iliopsoas muscle. In pubic bone fractures, eight muscles push bone fragments downward, the strongest among them being m. adductor magnus. Two muscles pull them upwards: m. rectus abdominis and m. obliquus externus. Nine muscles are responsible for downward displacement of bone fragments in ischiadic fractures, but the strongest is m. semitendinosus. Calculation of moments of muscle forces acting upon bone fragments using CT of pelvic fractures gives additional data for planning of optimal operative treatment that can guarantee stable fixation in individual patients.

RESUMO

Aim of our study was to compare anterior cervical fusion with fusion augmented with dynamic implants and with the first generation-plate. Methods. Patients with radiculopathy and/or myelopathy were included in a prospective cohort study. Clinical outcome was assessed according to the Nurick, Odom, and SF 36 scales. Rotation and translation of screws, and quality of fusion (Tribus) were assessed at the 6-week and 4-year follow-up examinations. Neurodecompression was performed in 81 patients (one-level N = 45, two-level N = 26 and multi-level N = 10) in the period from January 2001 to September 2003. 50 male and 31 female patients were divided into three groups, depending upon type of fusion: 1. Augmented with dynamic implants (N = 33), 2. Augmented with H-plate (N = 33), and 3. Non-augmented (N = 15), one-level. There were no significant differences in clinical outcomes between the groups. Dynamization was detected in both augmented groups: axial in the dynamic implant group (mean translation +/- SD = 2.67 +/- 0.79 mm), and angular in the H-plate group (angle of rotation 7.2 degrees +/- 3.04 degrees). Six-week fusion was significantly better in the dynamic implants and non-augmented groups, as compared with the H-plate group. Two patients in the H-plate group developed pseudoarthrosis, 7 patients in the dynamic implant group had supradjacent segment heterotopic ossification and two of these additional ankylosis. Three patients in the non-augmented group had dislodgement of the bone graft with transient dysphagia in one of them. Our results suggest that selection of implants is not crucial for clinical outcome. Subsidence is allowed with both fixation systems. Fusion is faster and more effective in the axially dynamized group.

RESUMO

The paper is a clinical retrospective analysis of free conjunctival autograft in treatment of pterygia. In period from 1998 until 2006, 47 patients with pterygia were operated using free conjunctival autograft. There were 19 female and 38 male, average age 61 years. In the majority of patients (39/47) it was a primary pterygia. Eight patients were on topical antiglaucoma therapy. Free autograft was taken from superotemporal conjunctiva. Introduction of a single nylon suture to mark the epithelial side of the graft as well as the use of running 10-0 nylon suture for the graft that stays in up to two months, were our modifications of the standard technique. The mean follow-up was 18.7 +/- 9.8 months. Free conjunctival autograft was successfully taken in all patients. Four of them experienced transient graft edema. In glaucoma patients, delayed healing of the cornea, conjunctival harvest area and the graft was noted. The best corrected visual acuity was improved in all patients, from 1-3 Snellen lines. Recurrence of the pterygium was noted in three patients, two of them already with recurrent pterygium. Free conjunctival graft is a safe and effective method of pterygium surgery that produces only few complications and has low recurrence rate. We found useful switch from topical to systemic antiglaucoma therapy as well as adjunctive use of autologous serum drops in promoting and accelerating healing in glaucoma patients.

RESUMO

INTRODUCTION: The purpose of the present study was to evaluate and compare the long-term results of operative treatment of a multifragment fracture of the inferior patellar pole by basket plate osteosynthesis and partial patellectomy. MATERIALS AND METHODS: We retrospectively studied two groups of patients who had operative treatment of a multifragment fracture of the inferior patellar pole between 1988 and 2004. Seventy-one patients who had osteosynthesis by basket plate (Group 1) and 49 patients who had partial patellectomy (Group 2) were followed for an average of 5.3 years. The final evaluation was based on the modified Cincinnati Knee rating system test. RESULTS: The results were excellent or good in 90.1% patients of Group 1, and 73.5% patients of Group 2. Significant differences between the groups were noted with regard to knee pain, swallowing, level activity, compression pain, range of motion, muscular atrophy, muscular strength, and final patellofemoral score which confirms statistical analysis. CONCLUSION: The stability of the osteosynthesis by basket plate allows osseous consolidation of the fracture and permits immediate mobilization and early weight bearing. Osteosynthesis by basket plate can provide better clinical results.

RESUMO

Purpose of the paper was to evaluate ocular optical components (OOC) interactions in a large number of emmetropes. A cross-sectional study of 1,000 emmetropes, aged from 18-40 years, has been conducted. Complete ophthalmological examination, corneal radius (CR) measurement, keratometry and echobiometry of both eyes were performed. The highest correlation of OOC was that of axial length (Ax) with vitreal body (CV) on both eyes (r = 0.79 for the right eye (RE); r = 0.81 for the left eye (LE)). The axial length had a positive correlation with the anterior chamber depth (ACD) on both eyes as well, but the coefficient was very low (r = 0.29 for the RE; r = 0.32 for the LE). The only negative correlation Ax had on both eyes was with the lens (L) (r = -0.17 for the RE; r = -0.19 for the LE). Keratometry of the horizontal (K1) and vertical meridian (K2) showed a negative correlation with CV and Ax on both eyes (for K1 r = -0.64 for CV r = -0.54 for Ax; for K2 r = -0.67 for CV r = -0.68 for Ax). CR had a positive correlation with Ax (r = 0.74) and CV (r = 0.79). It showed a negative correlation with L (r = -0.58). CV had a high, positive correlation with Ax (r = 0.72 for the RE; r = 0.75 for the LE). The correlation with K1 and K2 was negative. Our study showed that the axial length, keratometry, corneal radius, lens thickness and vitreal body were the most important OOC that correlated with each other following a pattern in our group of emmetropes. They interacted in such a way that in the subjects with axial length above the average value, the vitreal body was longer but the lens was thinner and the cornea was of less power. This could explain at least one of the mechanisms of emmetropization.

RESUMO

The paper presents our approach to reconstruction after periocular basalioma (pBCC) excision, especially of large lower lid (LL) and medial canthal (MC) pBCC. Retrospective analysis of data of 123 patients with pBCC, confirmed on histologic examination (HE), operated in period from 1998 to 2006, was performed. Oncologic safety margins of 3 mm were marked after local anesthesia was administered. Reconstruction was done in time of surgery. In pBCC away from a lid margin, adjacent myocutaneous flaps were used. For lid margin involving (LM) pBCC, size of 10 mm and less in horizontal diameter (HD), full-thickness lid excision was performed, combined with lateral canthotomy and/or Tenzel or McGregor flap. When size of LM pBCC was more than 10 mm in HD and it was on a LL, ipsilateral upper lid (UL) tarsoconjunctival (TC) graft combined with single pedicle transposition myocutaneous flap were used. The same size of LM pBCC on a UL required ipsilateral full-thickness LL "switch" flap and/or contralateral LL Hübner graft. In MC pBCC combined approach was used. The follow-up was up to 5 years. The 19 patients (15.4%) had positive tumor margin on HE. Five of them refused further surgery, but only two had recurrence. The rest of 121 patients had no recurrence during follow-up. In 5/14 patients, who underwent additional surgery, no tumor cells were found on HE. The 10/123 patients (8.1%) had complications. The imperative of our approach to reconstruction after pBCC was good functional and cosmetic result, avoiding prolonged lid closure. Accordingly, in large LL LM pBCC we used ipsilateral UL TC graft combined with single pedicle transposition myocutaneous flap. In MC pBCC combined approach was mandatory.
