RESUMO
BACKGROUND: The muscular sculpture (MS) is a new technique of male body contouring to achieve: tight skin that very well reveals muscular bulk, a male muscular and athletic body, minimal observable scars and even patients who are not, nor have been in. With this study, we describe the new technique for sculpting of lower extremities. In literature are not described techniques to accomplish a sound aesthetic result in sculpting surgery about lower extremities. METHODS: For this surgical procedure, we illustrate the technique that was obtained from 5 male patients (principles outlined in the Declaration of Helsinki have been followed). We describe this surgery with six steps: defatting step; MS; internal scar removal; irregularity removal; dermal grasping; last residues of fat removing. RESULTS: We obtain a high satisfaction rate as high as 100% for short and long term. Compared to the complications more described in literature (infection, hematoma, seroma, wound dehiscence, hypertrophic scars, sensory nerve injury and recurrent skin laxity, Monarca and Rizzo in Aesthetic Plast Surg 39(2):199-202, 2015), we have not had complications. We had no major complications. We observed, with our other studies, a direct relationship between complications and smoking habit. Successful body-contouring surgery requires a patient to embrace positive lifestyle habits: exercise, a proper diet and other positive lifestyle changes (Monarca et al. in Plast Reconstr Surg 123(5):1637-1638, 2009), and a high compliance and to avoid all the excesses. CONCLUSIONS: We obtain amazing aesthetic results with total patient satisfaction without complications. There are not enough studies in the literature about body sculpting, and is necessary to deepen this technique in order to obtain increasingly encouraging results.

OBJECTIVE: This study evaluates long-term outcomes in adults with Unilateral and Bilateral Cleft Lip and Palate (UCLP/BCLP) treated during the period 1992 to 1995 with tibial periosteal graft in primary repair. DESIGN: Retrospective study. SETTING: Department of Plastic and Maxillofacial Surgery, Children's Hospital Bambino Gesù (Italy). PATIENTS: The study included 52 patients with non-syndromic BCLP/UCLP who met the inclusion criteria. INTERVENTIONS: All patients underwent a standardized surgical protocol using a tibial periosteal graft as primary repair of the hard palate. MAIN OUTCOME MEASURE(S): Long-term outcomes on maxillary growth, residual oronasal fistula, and leg length discrepancy. RESULTS: About <2% of patients showed oral-nasal communication. Mean value of maxillary depth was 86° ± 4.5°. The lower value for maxillary retrusion was 76.8° in relation to the Frankfurt plane. At the x-ray control, 12.2% of patients showed leg discrepancy with a difference of always <2â cm. CONCLUSIONS: The rate of maxillary retrusion obtained was the same if compared to other techniques. Tibial periosteal graft reduces the risk of fistula and the need for reintervention after secondary bone graft. The study did not observe negative impacts on leg growth after 25 years.
RESUMO
Background and Objectives: Previous literature has disclosed that facial attractiveness affects the esthetic evaluation of nose and lip deformity on frontal and lateral photographs. However, it has never been debated if the removal of the external facial features on three-dimensional (3D) models ("cropped assessment bias") could provide a considerable usefulness in the interpretation and comparison of the results. Additionally, it has been assumed on two-dimensional (2D) studies that esthetic assessment biases with respect to observer gender, and it is not acknowledged if and to the extent that "gender assessment bias" may be influenced by a three-dimensional layout. The aim of this study is to investigate if facial traits and observers' gender may affect the esthetic ratings of unilateral cleft lip and palate (UCLP) patients after soft tissue reconstruction. Materials and Methods: Three-dimensional images of ten UCLP patients' images were acquired before the intervention (T0), one-month (T1) and six-months (T2) postoperative. Geomagic® software (version 2014; 3D Systems, Rock Hill, SC, USA) was used to remove the external facial features of 3D surface models. Five-point scale developed by Asher-McDade et al. was used to rate both nasolabial attractiveness and impairment for full-face (FF) and cropped-face (CF) 3D images. Forty-three judges (21 males, 22 females) were enrolled for the esthetic evaluation. Intraclass correlation coefficient (ICC) was used to test intra- and inter-examiner reliability; a value of 0.7 was set as the minimum acceptable level of reliability. Results: When comparing the 2 sets of observations (FF and CF), the ICC ranged from 0.654 to 0.823. Concerning gender assessment bias, the ICC ranged from 0.438 to 0.686 and from 0.722 to 0.788 for males and females, respectively. Concerning inter-examiner reliability, ICC for questions 2-7 ranged from 0.448 to 0.644 and from 0.659 to 0.817 at T0 and T2, respectively. Conclusions: The removal of external facial features provides subtle differences on the esthetic assessment of UCLP patients. Moreover, based on our data, examiners' gender differences may affect esthetic assessment of UCLP patients. Despite the subjectivity of esthetic judgments, a reliable, validated and reproducible scoring protocol should consider the influence of gender differences on 3D esthetic assessment of UCLP patients.

Cancer stem cells (CSCs) are a group of cells with eternal life or infinite self-renewal ability, which have high migrating, infiltrative, and metastatic abilities. Though CSCs only account for a small proportion in tumors, the high resistance to traditional therapy exempts them from therapy killing and thus they can reconstruct tumors. Previous studies found that heterogeneity of cancer cells extensively exists in head and neck cancers. Our current knowledge, about CSCs in the laryngeal cancer (LC), largely depends on head and neck studies. Given the lack of systematic data about CSCs in LC, we propose a review of the literature, reporting the evidences of CSCs in tumorigenesis of LC, with the purpose to provide new insights into the prevention and/or treatment of laryngeal carcinoma.

PURPOSE: Retromolar trigone (RMT) tumours are rare and aggressive malignancies, which require an aggressive surgical approach. The reconstruction oral cavity defects represent a challenge because of the critical role of this area both aesthetically and functionally. Free radial forearm (RF) or anterolateral thigh (ALT) flap are the first choice for the repair of intraoral defects. In reviewing the literature, there is lack of evidence pertaining to the differences between RF and ALT flaps in the reconstruction of patients with RMT tumours. This study evaluates the better microvascular reconstruction after RMT cancer resection. METHODS: Thirty patients with RMT cancer underwent oropharingectomy and microvascular reconstruction using the free RF flap (RF group) and the ALT perforator flap (ALT group). The two groups were homogeneous for sex, age, anatomic area, body mass index, and clinicopathologic profile. Viability, complications, scarring, cosmetic appearance, disorder of sensations, ROM, disease-specific items and satisfaction rate were analyzed, and statistical analysis was performed. STUDY DESIGN: Prospective study. RESULTS: There were differences between the RF and ALT groups in the morphofunctional outcomes, both short-term and long-term follow-up. These differences were statistically significant (p < 0.05) for donor site complications, cosmetic appearance, and scar evaluations. Manual dexterity was slower on the operated donor side than on the nonoperated side in the 33.3 % in the RF group. CONCLUSIONS: The study showed that the free ALT perforator flap provides better results in appearance and scarring than the RF flap for intraoral reconstruction after RMT cancer resection.

Radiotherapy represents a major problem in facial surgery. Orbital and periorbital radiation therapy causes a contraction of the soft tissues. Scarring with ectropion is the most severe complication, with shrinking of the anterior lamella, skin dystrophy, muscle atrophy, and alteration of the remaining soft tissues. Goals for reconstruction include correction of distorted orbitofacial tissues and the restoration of orbital structures. The management of these patients is not standardized. We suggest systematically using a combined approach of surgery and lipofilling to restore the orbital deformity and dystrophy, respectively. For this purpose, we present the case of a 65-year-old woman with asymmetry of the orbital regions and severe lower eyelid cicatricial ectropion due to multiple radiation treatments in childhood for an extensive cavernous hemangioma of the right side of the face. We performed a reconstructive procedure using a tarsal strip technique in association with contralateral upper eyelid graft to correct the extensive retraction of the right lower eyelid and lid asymmetry. Subsequently, the patient underwent lipofilling to correct the post-radiotherapy dystrophy. Skin texture, softness, and elasticity greatly improved with further symmetrization. The combined treatment with surgery and lipofilling can significantly improve the functional and cosmetic outcome of shortened and dystrophic eyelids with a successful result with regard to post-radiotherapy retraction.

BACKGROUND: Reconstruction of face deformities resulting from skin cancer includes reconstructing the area with similar tissue. This prospective study aimed to compare the functional and aesthetic outcomes between two types of local flaps (the island pedicle flap vs the bilobed flap) used in reconstruction of the ala and back nose. METHODS: In this study, 120 patients with skin cancer of the nose underwent ala and back reconstruction: 60 patients using the island flap (IF group) and 60 patients using the bilobed flap (BF group). The two groups were homogeneous for sex, age, and anatomic area. Complications, scarring according to the scale of Vancouver, cosmetic appearance, and disorders of sensations were analyzed, and statistical analysis was performed using Chi-square and analysis of variance (ANOVA). RESULTS: Early complications were more common in the BF group than in the IF group (p < 0.005). The Vancouver Scar Scale scores were significantly better for the IF patients (p < 0,005), who also showed better results in the analysis of cosmetic outcomes (p < 0.005). CONCLUSION: The study showed that the island flap used for ala and back nose reconstruction provides better functional and cosmetic results than the bilobed flap, from both functional and aesthetic points of view. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Basal cell carcinoma (BCC) is the most common type of cancer in Europe, Australia and the U.S.A. After nasal skin cancer excision, especially if it is less than 1-2 cm in diameter, several surgical techniques can be used to reconstruct the lack of substance.In the management of our two patients we have chosen to utilize, instead, a well-known plastic surgery technique, Z-plasty, which is both easy to perform that effective to achieve excellent cosmetic results. As shown by our two clinical cases, the use of Z-plasty for lack of substance of the nose tip and bridge can be extremely effective in terms of cosmetic results. In comparison with the other reconstructive techniques, in fact, it is very easy to perform and allows to avoid or minimize the distortion of the nasal tip and wing, to orient the incision along the skin tension lines and, finally, to replace the lack with very similar structures regarding color, thickness and tissue architecture to those removed.

BACKGROUND: Upper-lip augmentation is used to enhance a thin upper lip or correct lip deficiencies or senile hypotrophy. We describe an easy, effective, and reproducible technique. METHODS: We use two preseptal orbicularis oculi muscle grafts that provide a reliable option for soft-tissue upper-lip augmentation, with improved vertical lip height and lateral lip projection and reappearance of the Cupid's bow. Muscle grafts are harvested from a blepharoplasty done at the same time. RESULTS: The advantages of this procedure include the creation of an anatomically natural upper lip through preserving the continuity and function of the labial structure, good augmentation, no donor-site morbidity, no visible scars on the vermilion, and successful rejuvenation with the associated blepharoplasty. CONCLUSION: Both patients and surgeons were satisfied with the results because the muscle grafts produce a youthful appearance by adding natural, soft roundness and fullness to the upper lip without an artificial look or the use of synthetic material, providing long-term augmentation.

The presence of circulating tumor cells (CTCs) in the blood of patients with metastatic breast, colorectal and prostate cancer have been widely investigated; however, few studies have examined CTCs in patients with laryngeal cancer. The present pilot study aimed to detect pre- and postoperative CTCs in the blood of patients with laryngeal cancer and evaluate the association with prognosis. Eight patients with laryngeal squamous cell carcinoma (LSCC) at stage III were included in the present study and underwent total or subtotal laryngectomy and radical bilateral neck lymph node dissection. Blood samples were collected from all patients before and after surgery at different time-points. The following processing steps were followed; preoperative blood sampling, surgery, postoperative blood sampling at 3, 6 and 12 month follow-ups, and prognostic association analysis. CTCs were retained on ScreenCell filters for cytological characterization. The presence of CTCs was associated with a less favorable prognosis, whereas a decrease of CTCs in the postoperative sampling was observed in patients who exhibited an improved therapeutic response. The results of the present pilot study revealed a possible association between the presence of CTCs and a less favorable prognosis in patients with LSCC; therefore, these preliminary findings may encourage further research into the incorporation of a liquid biopsy in the management of LSCC, as this may help identify patients with occult metastatic disease earlier and in a non-invasive manner. In addition, this approach may represent novel independent prognostic factor for use in the clinical evaluation of patients with LSCC.
RESUMO
BACKGROUND: Macromastia is a health problem that requires the coordination of surgical and medical specialists. Goals of reduction mammaplasty are to alleviate physical, emotional and psychosocial discomforts and to restore a conical-shaped breast, maintaining scars as short as possible. We report our approach for reduction mammaplasty with superior pedicle. MATERIALS AND METHODS: Our method combines advantages of round block with vertical scar, using a dermal flap that is fixed to the new mammary crease. We analyzed skin and glandular resection customizing the mammaplasty. RESULTS: The dermal flap works against the weight of residual tissue, maintaining the crease at the desired position with a natural result. Benefits are an excellent projection, short scar, suitable reshaping and patient satisfaction. CONCLUSION: This technique can be used for mild to severe hypertrophy with various degrees of ptosis. It results in a successful aesthetic outcome with minimal scarring, suitable breast remodeling and natural long-lasting projection.

BACKGROUND: Facial hemiatrophy, a typical manifestation of Parry-Romberg syndrome, produces massive face asymmetry, causing marked aesthetic damage and severe psychological discomfort, with repercussions to the psychophysical status of the patient. This article presents a successful combined treatment that results in resolution of symptoms and patient satisfaction. METHODS: The authors proposed a clinic-therapeutic management comprising a customized program of bio-lipo-intense pulsed light (IPL) remodeling. RESULTS: In 2007, at a 1-year follow-up visit, the patient presented a stable result. She is satisfied with the augmentation treatment, the new volume and contours of the face, and the resolution of the sclerosis and ochrodermia. CONCLUSION: The authors have succeeded with a minimally invasive reconstructive technique for Romberg disease using a customized therapeutic program of poly-L-lactic acid, lipofilling, and IPL therapy. They report a case of good healing without recurrences and complications, with a good cosmetic result, and with satisfaction of the patient.

PURPOSE: To quantify and compare pre-operative and post-operative volumetric adjustments of the upper lip tissues in patients with cleft lip. METHODS: The authors performed an anthropometric study and a quantitative analysis of the differences based on three-dimensional morphology of the nasolabial area. Twenty facial images using the three-dimensional stereophotogrammetry were taken from ten selected subjects on two separate occasions, sitting in natural head position. Facial landmarks were marked and measurements recorded, in order to calculate the volumetric adjustments in the soft tissues of the upper lip, comparing the preoperative and postoperative results. Student test and p-Value were performed for statistical analysis. RESULTS: The analysis of the 3D images showed variability with the pre- and postoperative volumes of the nasolabial area with: an increase of upper lip volume all patients; a complete view of the severity in the preoperative; and an improvement of the appearance in the postoperative. The amount of increase of the upper lip volume was established about 29,7%. For all measurements, the variability between pre- and post-operative was significant (p < 0.01). CONCLUSION: The 3D stereophotogrammetry technique allows a detailed preoperative evaluation and an accurate assessment of the surgical outcomes. The study provides a value of volumetric variation of the upper lip in individuals with cleft lip. KEY WORDS: Cleft lip, Nasolabial area, 3D Morphological Analysis, 3D Stereophotogrammetry, Upper lip volume.

BACKGROUND: Skin grafting is a frequent surgical procedure used to reconstruct a soft-tissue deficit. Tie-over bolster dressing is the traditional technique made to fix the graft to the recipient area. This dressing does not always provide satisfactory results in some difficult body areas, with poor skin graft taking as an outcome. Here, we used a soft "polyurethane sponge" as a compressive tool. MATERIALS AND METHODS: A therapeutic protocol was used to select patients, splitting them into 2 groups: tie-over bolster dressing versus polyurethane sponge. Data analysis and calculation of sample size were performed using the Statistical Package for the Social Sciences Windows version 13.0. RESULTS: Of the 106 patients treated by traditional compressive dressing, 11 had complications, thus achieving a success rate of 89.6%. Of the 106 patients treated by polyurethane sponge dressing, 3 had complications, providing a success rate of 97.1%. CONCLUSION: Compared with the conventional tie-over dressing, the sponge dressing technique was demonstrated to be more successful in graft taking in selected areas.

PURPOSE: To report a surgical algorithm for the treatment of bilateral cleft lip stigmata. METHODS: The investigators designs a retrospective study composed of patients with bilateral cleft lip stigmata. The surgical approach is on the basis of the severity of the deformity and of course the age of the patient. It consists in Simple scar revision with orbicularis muscle synthesis; Two dermal flaps tunneled in the central vermilion; Abbe flap. The investigators analyzes early and late complications, and performs the evaluation of the cosmetic appearance by a parent or patient himself/herself, a surgeon and a blinded third party observer. RESULTS: The sample was composed of 351 patients. At short-term follow-up, viability of the flaps, function and morphology are good. At long-term follow-up, we observed significant improvement of the characteristics and profile of the patient's face and a normal function of the lips. We recorded a good scarring and a high satisfaction rate by evaluation of patients/ surgeon/ blinded third party observer. CONCLUSION: The results of this study suggest that a surgical algorithm on the basis of the severity of the deformity and of course the age of the patient can represent an option of choice for most patients with bilateral cleft lip stigmata. KEY WORDS: Abbe flap, Bilateral cleft lip stigmata, Cleft lip, Dermal flaps, Orbicularis muscles.

Glaucomatous optic neuropathy is the most commonly acquired optic neuropathy encountered in clinical practice. It is the second leading cause of blindness globally, after cataracts, but it presents a greater public health challenge than cataracts, because the blindness it causes is irreversible. It has pathogenesis still largely unknown and no established cure. Alterations in serum antibody profiles, upregulation, and downregulation have been described, but it still remains elusive if the autoantibodies seen in glaucoma are an epiphenomenon or causative. Hypertension, diabetes, and hearing disorders also are associated. This review is a glaucoma update with focus about the recent advances in the last 15 years.

Hypertrophic pachymeningitis (HP) is a rare disorder that causes thickening of the dura mater. Inflammatory lesions may be located in the cerebral or spinal dura mater or, less frequently, in both locations simultaneously. Numerous clinico-pathological entities cause thickening of the pachymeninges. Indeed, HP is a potential manifestation of many different diseases, but the diagnosis often remains uncertain. Cases in which the pachymeningitis has no known aetiology are termed "idiopathic" HP (IHP). Recently, it has been suggested that IgG4-related disease represents a subset of cases previously diagnosed as idiopathic hypertrophic pachymeningitis. Little is known regarding the pathogenic events of IHP. In a general theory, the inflammatory infiltrate, mainly consisting of B and T lymphocytes, activates fibroblasts and induces collagen deposition, leading to tissue hypertrophy and increased dural thickness. Clinical manifestations of IHP depend upon the location of the inflammatory lesions and compression of the adjacent nervous structures. Three central pathological features are lymphoplasmacytic infiltration, obliterative phlebitis, and storiform fibrosis. MRI is the examination of choice for the preliminary diagnosis of IHP. Histopathological examination of a biopsy specimen of the dura mater would finally confirm the diagnosis. The differential diagnosis for HP is broad and includes infections, autoimmune disorders, and neoplasia. Currently, there is no consensus about treatment for patients with IHP. There is a preference for glucocorticoid treatment on diagnosis followed by the addition of other immunosuppressive agents in the event of a recurrence. Rituximab is used in patients who did not respond to glucocorticoids or to conventional steroid-sparing agents.
