Long-Term Outcomes of Arthroscope-Assisted Bone-Ligament-Bone Reconstruction for Nonstatic Scapholunate Ligament Injury.

BACKGROUND: Scapholunate ligament injury is the most common cause of carpal instability. This retrospective case series aimed to assess the effectiveness and the maintenance of the results obtained by reconstructing the scapholunate ligament with a bone-ligament-bone autograft through an arthroscope-assisted minimally invasive approach. METHODS: Thirty-six patients were enrolled initially but only 31 constituted the final population study (23 male, eight female; median age, 38 years; age range, 18 to 55 years). Radiographic (posteroanterior and true lateral radiographs to assess the scapholunate gap, radiolunate, and capitolunate angles; computed tomographic scan; magnetic resonance images), functional [grip strength (Jamar test and pinch test), active range of motion], and subjective (patient-rated wrist evaluation test) outcome measurements were collected. Minimum follow-up was 50 months. RESULTS: Grip strength and wrist mobility were significantly improved from the preoperative values and improved over time. No scapholunate synostosis or carpal bone necrosis was observed. No wrist showed any sign of arthrosis or progression towards wrist instability. Only four patients had scapholunate gap greater than 3 mm. CONCLUSIONS: The proposed technique for scapholunate reconstruction, providing a biologic reconstruction of both the volar and dorsal portion of the scapholunate ligament and avoiding extensive capsulotomy, obtained significant functional outcomes improvement that was maintained over time and prevented degenerative changes to the articular surfaces. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

The First Use of Human-Derived ADM in Prepectoral Direct-to-Implant Breast Reconstruction after Skin-Reducing Mastectomy.

INTRODUCTION: Large and ptotic breasts always represented a great reconstructive challenge for plastic surgeons. In order to deal with these patients, we started performing Wise-pattern skin-reducing mastectomies (SRM) followed by direct-to-implant breast reconstructions (DTI-BR) in the prepectoral space where the implants were covered with the autologous adipo-dermal flap and a human acellular dermal matrix called MODA. MATERIALS AND METHOD: We retrospectively reviewed all patients that underwent Wise-pattern SRM followed by MODA-assisted, prepectoral, DTI-BR between January 2017 and November 2019 at our Institution. Inclusion criteria were large ptotic breast and pinch test >2cm, while exclusion criteria were smoking >10 cigarettes/day, history of prior radiotherapy, patients supposedly requiring breast implants bigger than 550cc or post-mastectomy radiotherapy. Patients' data were collected through their electronic medical records. Both short- and long-term outcomes were reported. RESULTS: Seventeen patients underwent Wise-pattern SRM followed by MODA-assisted, prepectoral, DTI-BR for a total of twenty-one breast reconstruction and fourteen matching procedures. Mean follow-up was 13.4 months (SD= ±3.67). No major complication was reported. Three (14.3%) reconstructed breasts had minor complications: 2 (9.5%) minimal (<1cm2) wound dehiscence and 1 (4.8%) de-epithelization of the skin at the T junction that were treated conservatively. Drainages gave mean output of 410.59 ml (SD= ±214.83) and were kept in place on average for 8.59 days (SD= ±3.45). CONCLUSION: Few are the reports in the literature regarding DTI-BR following SRM and even fewer are those where BR was performed in the prepectoral space. Our work demonstrated the safety of prepectoral DTI-BR following SRM in selected patients in accordance with the "conservative reconstruction" principles. Furthermore, we confirmed the reliability of MODA in accordance with previously published works. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

"Bifidus pedicle", The Use of Bilobed Superomedial Pedicle for Breast Reshaping Following Upper Outer Quadrantectomy: A New Oncoplastic Breast Surgery Technique.

INTRODUCTION: The aim of this work was to describe our technique, the "Bifidus pedicle", which is a modification of the superomedial pedicle, for managing large breast cancers (BCs) in the upper outer quadrant (UOQ) in patients with medium/large breasts and associated ptosis. Observed complications, cosmetic outcome and oncologic safety were also reported. MATERIALS AND METHODS: Thirty patients underwent our modification of the superomedial pedicle combined with a Wise skin resection pattern for large BCs in the UOQ. All patients underwent contralateral Wise pattern breast reduction/mastopexy for symmetry. RESULTS: The average weight of the quadrantectomy specimen was 235 grams (range: 36-400 grams). Mean free tumour margin was 19.4 mm (range: 16-30). Mean operative time was 165 minutes (range: 150-220). Eight (13.2%) breasts had minor complications: two partial NAC necrosis, and six minimal wound dehiscences. Mean follow-up was 22 months (range: 12-30). Overall satisfaction rate was 91%; patients reported to be satisfied the most with the shape (92%) of the breasts, the achieved symmetry (94%), and the volume (85%), focusing on the fullness in the UOQ. CONCLUSIONS: Our Bifidus pedicle allowed to fill even wide defects in the UOQ, because we selectively employed it in patients with medium to large ptotic breasts where the lower pole had enough tissue to be displaced. Satisfactory cosmetic and oncologic outcomes were achieved with low complication rate. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Activity Evaluation of Facial Muscles by Surface Electromyography.

BACKGROUND: Surface electromyography (sEMG) is an easy, noninvasive, and reproducible way to assess spontaneous electrical activity of muscles in real time. In this study, we report data on the correlation between sEMG and mimetic muscle activity during specific tasks so as to create a case-control reference for future studies on acute, chronic, and congenital facial palsy. METHODS: Twelve healthy participants were enrolled (6 women and 6 men) with a mean age of 42.75 (range, 26-58 years) years. sEMG signals were recorded at rest and while performing voluntary and specific tasks that elicited selective contraction of frontalis, orbicularis oculi, zygomaticus major, orbicularis oris, and platysma muscles simultaneously and bilaterally for each muscle group. Statistical analysis was performed to evaluate if there was a statistically significant difference of the average contraction values between left- and right-side data sets and between male and female participants. RESULTS: No statistically significant difference was found between male and female participants or between the right and left sides at rest and while performing the requested tasks, even though they were not identical. No participant complained about the procedure. CONCLUSIONS: Interindividual and intraindividual variability of the sEMG signal as well as crosstalk between muscles groups were reported downsides that we did not encounter. The absolute noninvasiveness of our procedure makes it feasible to be applied even to young children. This dataset obtained in healthy participants might also be useful in the observation of patients undergoing regeneration/reinnervation procedure following recently acquired facial palsy or mimetic muscle reconstruction for congenital/inveterate one.

Vascular malformation and their unpredictable evolution: A true challenge for physicians.

Vascular anomalies are mainly divided into two groups: vasoproliferative/vascular neoplasms (e.g., hemangioma), and vascular malformations (VMs). The main difference between the two resides in the histopathological assessment, while vascular tumors are true neoplasm, typically congenital with rapid postnatal growth, and eventual slow regression; VMs have a single endothelial cell lining, tend to be regarded as acquired despite being congenital in nature, can undergo sudden and massive growth, miming neoplastic proliferation. Arteriovenous malformation (AVMs) are one type of fast flow VMs, with a four-stage natural history, and potentially disruptive evolution. Magnetic resonance is the gold-standard for diagnosis and pre-operative planning while computer tomography is particularly valuable for AVMs involving bones, and selective angiography can define source / draining vessels for sclerotherapy and surgical planning. Given their unpredictable evolution, AVMs shouldn't be treated until symptomatic, complicated, or aesthetically unacceptable. Surgical resection should be preceded by arterial embolization from 24 to 72 hours, which must be extensive in order to reduce the risk of recurrence. Pain due to ischemic condition is one of the most common and debilitating symptoms of AVM, while gassosus gangrene is the most feared complication as they can become pabulum for bacteria overgrowth eventually resulting in necrotizing fasciitis. Given their clinical evolution, VMs pose physicians at great challenge in identifying the best-suited treatment for each case. It is of paramount importance to be able to make accurate diagnosis, understand the basic physiology, and use appropriate diagnostic and treatment modalities to optimize outcome. Proper multidisciplinary approach along with constant psychological support is the basis for a successful final outcome. Aim of this work was to provide a deeper insight into these relatively uncommon pathology and related hardship that afflicts both patients and their families.

From liposuction to adipose-derived stem cells: indications and technique.

BACKGROUND AND AIM OF THE WORK: Adipose tissue is an organ of energy storage, an endocrine organ, a soft tissue filler and a cosmetically unnecessary tissue discarded by liposuction. Liposuction was designed to correct unaesthetic deposits of subcutaneous fat; it produces satisfactory silhouette contouring when performed by appropriately trained operators using properly selected technologies. However, from lipoaspirate it is possible to obtain autologous fat graft and adipose-derived stem cells (ASCs) for reconstructive surgery and regenerative medicine. Autologous fat transplantation uses include the correction of body contour, malformations and post-surgical outcomes. The regenerative properties of ASCs allow treating damaged tissues such as wounds, burns, scars and radiodermatitis. The aim of this study was to perform a literature review highlighting the crucial role of adipose tissue in plastic and reconstructive surgery, from liposuction to lipofilling and ASCs, exposing the indications, procedures and complications of these surgical techniques. METHODS: Literature review of publications concerning liposuction, lipofilling and adipose-derived stem cells (ASCS). RESULTS: The introduction of liposuction allowed the use of adipose tissue for many clinical uses. The adipose tissue filling properties have been highlighted by the advent of lipofilling. The regenerative properties evidence of autologous fat transplantation encouraged the research on the clinical use of ASCs. CONCLUSIONS: Adipose tissue is not only the main energy storage of our body but also an important source of stem cells that can be used in various fields of regenerative medicine and tissue engineering with encouraging results for the future.

Single center evidence for the treatment of basal cell carcinoma of the head and neck.

AIM: Basal Cell Carcinoma (BCC) alone accounts for 80% of cases of non-melanoma skin cancer (NMSC), which characteristically develops on sun-exposed skin. Indeed the most common site of BCC is the head and neck region (80%). The purpose of this study to review the experience of our center with BCC in the head and neck region to report the sites of occurrence and treatment. MATERIALS AND METHOD: We retrospectively reviewed 77 patients with BCC of the head and neck, who revived surgical treatment within our plastic surgery division. Basic demographic data, cancer site and size, surgical treatment and histological data were collected. The mean follow-up period was 12 months. RESULTS: The study population included 37 males and 40 females, with a mean age of 74.12 years. The nasal unit was the main site of BCC (31.82%), followed by the periorbital (13.64%) and cervical (12.5%) units. Primary closure was the main surgical procedure performed (72.5%), followed by local flap (26.1%) and full-thickness skin grafts (1.4%). The safety resection margin ranged from 4.5 to 9 mm, with a 98.7% complete removal rate. Neither recurrence nor any newly-developed lesions were reported during follow-up in any patient. DISCUSSION: Our work reflects the shift in the incidence of BCC, which now seems to be more frequent in females. Furthermore, our data strengthens the association between UVR exposure and BCC, confirms its predilection to occur on the nasal unit and validates surgical excision as the gold standard treatment for skin cancer.

Breast reconstruction with breast implants.

BACKGROUND: Breast cancer is the most common noncutaneous malignancy among women worldwide. After a breast cancer removal procedure, women are asked to decide about breast reconstruction, mainly to improve their life quality, and they can choose from among many options. Broadly, there are two different types of breast reconstruction procedures: prosthetic implant-based reconstruction and autologous tissue-based reconstruction. METHODS: Implant-breast reconstruction is a minimally invasive procedure compared with autologous breast reconstruction. It is associated with fewer short- and long-term complications. RESULTS: The ideal candidates for implant-based reconstruction are patients with non-redundant soft tissue coverage, who desire a moderate sized non-ptotic breast and have not been previously irradiated. CONCLUSION: The state of the art for implant-breast reconstruction is briefly described in this article.

Trigger Site Inactivation for the Surgical Therapy of Occipital Migraine and Tension-type Headache: Our Experience and Review of the Literature.

Literature from the last decade has shown a correlation between resection of the occipital muscles and vessels and relief from migraine and tension-type headaches. METHODS: The aim of this article was to describe the authors' technique to treat occipital migraine, while comparing our approach with the other currently available surgical options. Relevant anatomical issues and their implications in the surgical treatment of occipital migraine have been reviewed. We undertook a modified version of the currently used method of occipital migraine surgery. Patients completed questionnaires before and after surgery, and results were compared. RESULTS: To identify all trigger points, we used a constellation of symptoms referred to by the patient rather than injection of botulinum toxin type A. The entire procedure was carried out under local anesthesia. In most of the patients (56) in whom a dilated/aneurysmal occipital artery was found, the procedure was limited to ligation of the occipital artery, with no further undermining of muscles or neurolysis, which reduced the invasiveness of the procedure. CONCLUSIONS: The main differences between our procedure and the currently used method were that (1) extensive undermining and muscular or nerve resection were not necessary and (2) no flap was transposed with the purpose of covering isolated nerves. Hence, our method could improve the currently used method, while minimizing its invasiveness.

Umbilical reconstruction: different techniques, a single aim.

The umbilicus is a unique physiologic scar of human life resulting from the healing process of the cut umbilical cord at birth. Its absence leads to an unnatural abdominal appearance, and an abnormally shaped or misplaced umbilicus may draw undue attention to the central abdomen. Loss of the umbilicus can be an embarrassing deformity; this occurs when older techniques of umbilical hernia or incisional hernia repair are employed and after abdominoplasty, urachal cyst repair, omphalocele repair, gastroschisis repair, some tumor excisions, and mobilization of bipedicled or bilateral TRAM/DIEP flaps for breast reconstruction. Umbilicoplasty, in which the umbilicus remains anchored to the deep abdominal fascia but is transposed through a newly-formed aperture in the upper abdominal skin flap, is performed in abdominoplasty either for abdominal flap harvest or purely for aesthetics. On the other hand, umbiliconeoplasty describes the de novo creation of an umbilicus that is absent for either congenital or acquired reasons. The optimal umbilical reconstruction should be reliable, reproducible, aesthetically appropriate, and associated with low morbidity. Ideally, it is also single-staged, except in the case of an infected wound, in which case a delayed primary approach may be prudent. (www.actabiomedica.it).

A three-year experience with medial-pedicle-based breast reduction for different mammary hypertrophy.

BACKGROUND AND AIM: The aim of breast reduction is to reduce excessive breast volume, ensuring an adequate vascular supply and sensitivity of the nipple-areola complex, as well as to produce an aesthetically pleasing final shape. The authors report on their experience with medial-pedicle-based breast reduction combined with both vertical and inverted-T skin resection patterns for different types of breast hypertrophy. METHODS: From January 2012 to June 2015, 27 female patients (mean age: 49 years) underwent reduction mammoplasty with the medial pedicle technique. The choices of medial pedicle base widths were: 6 cm for low-grade mammary hypertrophy (350-500 gr per breast), 6-8 cm for medium-grade hypertrophy (500-1000 gr per breast), or 8-10 cm for severe mammary hypertrophy (>1000 gr per breast). The authors chose the model of vertical skin resection for low-grade breast hypertrophy. The vertical model was used for medium-grade breast hypertrophy, and Wise skin resection was chosen on a case-by-case basis; only the Wise model was applied to severe breast hypertrophy.  Results: The mean weight of breast excised was 540 g on the left (range, 207 to 1160 g) and 564.8 g on the right (range, 215 to 1150 g). The complications were minor and self-limiting. All patients reported relief of neck pain, back pain, and bra strap indentations after 6 months of follow-up. CONCLUSIONS: Breast reduction surgery must address both functional and aesthetic issue by restoring an aesthetically pleasing shape to ptotic or hypertrophic breasts, repositioning the NAC in a physiological position. Various breast reduction techniques have been attempted to combine the safety of the pedicle with aesthetic and functional results. Surgeons should tailor the best technique to each patient. We found that medial-pedicle-based reduction mammoplasty is effective and reliable because it can be applied to a wide range of breast hypertrophy, with reproducible breast weight reduction and results that are aesthetically satisfactory for both patients and surgeons.

Surgical therapy of cutaneous squamous cell carcinoma: our experience.

INTRODUCTION: Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer, with an excellent prognosis after surgical removal. However, nodal metastasis are present in about 5% of cases and the death rate is about 2%. PRESENTATION OF CASE: The aim of this study is to report our experience about the surgical treatment of cSCC at the Cutaneous, Regenerative, Mininvasive and Plastic Surgery Unit, University of Parma, Italy, between January 2014 and February 2016. We statistically analyzed the group of patients regarding the average age, gender, localization and size of the lesions. The surgical margins of the excisions are studied and we report the results obtained after a follow up of 3 to 25 months. DISCUSSION: Between January 2014 and February 2016 in our Cutaneous, Regenerative, Mininvasive and Plastic Surgery Unit, we removed 36 squamous cell carcinomas, including 11 cSCCs in situ. The average annual incidence of squamous cell carcinoma in northeast of Italy is about 28,9  cases per 100,000 individuals.The number of cSCCs that we removed is lower than the Italian average. In our opinion, this is due to an increase in the early diagnosis of precancerous lesions and their medical or surgical treatment. This reduces the incidence of squamous cell carcinomas developing from precancerous lesions. CONCLUSION: The excision of cutaneous squamous cell carcinoma should be undertaken with a safety margin of at least 0.9 mm to minimize recurrence and metastasis.

Nose defects reconstruction with the Zitelli bilobed flap.

The skin cancers of the head and neck district are localized mostly on the nose, which, by being in the center of the mid-face, has an important aesthetic role. Therefore, many reconstructive techniques have been studied; among them regional skin flaps appeared the most suitable since they guaranteed the oncological radicality as well as a good aesthetic outcome. In this paper, we present our experience with the use of the Zitelli bilobed flap, which is defined as a double transposition flap for the reconstruction of the nose defects. From 2008 to 2012, we have treated 86 patients (56 men and 30 women, aged between 47 and 83 years) for skin cancer of the nose (72% basal-cell carcinoma, 28% squamous cell carcinoma); for all patients, the nose defects' reconstruction was performed by means of the modified Zitelli bilobed flap. The results were evaluated by short- and long-term follow-up; no infections or major complication were reported, while high preservation of the patient's facial characteristics and normal functions of the nose were observed. In 12 cases, little distortions of the alar rim were recorded although these patients still evaluated the cosmetic outcome as good. In our experience, the Zitelli bilobed flap remains a robust and reliable tool for the reconstruction of the nose defects, since it preserves its function, while ensuring a good aesthetic result.

Surgical Therapy of Temporal Triggered Migraine Headache.

BACKGROUND: The auriculotemporal and zygomaticotemporal nerves are the 2 primary trigger points in the temporal area of migraine headache. Different surgical approaches are described in literature, either open or endoscopic ones. METHODS: We described and delineated the currently adopted strategies to treat temporal trigger points in migraine headache. Furthermore, we reported our personal experience in the field. RESULTS: Regardless of the type of approach, outcomes observed were similar and ranged from 89% to 67% elimination / >50% reduction rates. All procedures are minimally invasive and only minor complications are reported, with an incidence ranging from 1% to 5%. CONCLUSIONS: Just like upper limb compressive neuropathies, migraine headache is believed to be caused by chronic compression of peripheral nerves (ie, the terminal branches of trigeminal nerve) caused by surrounding structures (eg, muscles, vessels, and fascial bands) the removal of which eventually results in improvement or elimination of migraine attacks. Particular attention should be paid to the close nerve/artery relationship often described in anatomical studies and clinical reports.

One-Stage Immediate Breast Reconstruction: A Concise Review.

BACKGROUND: One-stage direct-to-implant immediate breast reconstruction (IBR) is performed simultaneously with breast cancer resection. We explored indications, techniques, and outcomes of IBR to determine its feasibility, safety, and effectiveness. MATERIAL AND METHODS: We reviewed the available literature on one-stage direct-to-implant IBR, with or without acellular dermal matrix (ADM), synthetic mesh, or autologous fat grafting. We analyzed the indications, preoperative work-up, surgical technique, postoperative care, outcomes, and complications. RESULTS: IBR is indicated for small-to-medium nonptotic breasts and contraindicated in patients who require or have undergone radiotherapy, due to unacceptably high complications rates. Only patients with thick, well-vascularized mastectomy flaps are IBR candidates. Expandable implants should be used for ptotic breasts, while anatomical shaped implants should be used to reconstruct small-to-medium nonptotic breasts. ADMs can be used to cover the implant during IBR and avoid muscle elevation, thereby minimizing postoperative pain. Flap necrosis, reoperation, and implant loss are more common with IBR than conventional two-staged reconstruction, but IBR has advantages such as lack of secondary surgery, faster recovery, and better quality of life. CONCLUSIONS: IBR has good outcomes and patient-satisfaction rates. With ADM use, a shift from conventional reconstruction to IBR has occurred. Drawbacks of IBR can be overcome by careful patient selection.

Off-label use of adipose-derived stem cells.

BACKGROUND: Adipose-derived stem cells (ASCs) have a broad range of clinical applications. The ease of cell harvest and high yield with minimal donor-site morbidity makes adipose tissue an ideal source of stem cells. Further, the multi-lineage potential of these cells present significant opportunities within the field of tissue engineering, with studies successfully demonstrating their ability to produce a range of tissue types. MATERIALS AND METHODS: Literature review of publications on the use of ASCs, in the context of current European and US regulations. RESULTS: According to European and US regulations, many clinical trials reported in literature to date could be considered off-label. CONCLUSION: In Europe, clinical trials involving cultured ASCs and/or the use of collagenase, which causes changes in the structural and functional properties of stem cells, and/or ASCs application in non-homologous tissue, should be considered off-label. ASCs should be non-cultured, isolated mechanically, and used only in the subcutaneous tissue.

Breast reconstruction with anatomical implants: A review of indications and techniques based on current literature.

One important modality of breast cancer therapy is surgical treatment, which has become increasingly less mutilating over the last century. Breast reconstruction has become an integrated part of breast cancer treatment due to long-term psychosexual health factors and its importance for breast cancer survivors. Both autogenous tissue-based and implant-based reconstruction provides satisfactory reconstructive options due to better surgeon awareness of "the ideal breast size", although each has its own advantages and disadvantages. An overview of the current options in breast reconstruction is presented in this article.

Tissue expansion for breast reconstruction: Methods and techniques.

OBJECTIVE: In this work, the authors review recent data on the different methods and techniques of TE/implant-based reconstruction to determine the complication profiles and the advantages and disadvantages of the different techniques. This information will be valuable for surgeons performing breast reconstructions. MATERIALS AND METHODS: A thorough literature review was conducted by the authors concerning the current strategy of tissue expander (TE)/implant-based breast reconstruction following breast cancer surgery. RESULTS: Loss of the breast can strongly affect a woman's personal and social life while breast reconstruction reduces the sense of mutilation felt by women after a mastectomy, and provides psychosocial as well as aesthetic benefits. TE/implant-based reconstruction is the most common breast reconstructive strategy, constituting almost 65% of all breast reconstructions in the US. Although numerous studies have been published on various aspects of alloplastic breast reconstructions, most studies are single-center observations. No evidence-based guidelines are available as yet. Conventional TE/implant-based reconstruction can be performed as a two-stage procedure either in the immediate or delayed setting. Moreover, the adjunctive use of acellular dermal matrix further broadened the alloplastic breast reconstruction indication and also enhanced aesthetic outcomes. CONCLUSIONS: TE/implant-based reconstruction has proved to be a safe, cost-effective, and reliable technique that can be performed in women with various comorbidities. Short operative time, fast recovery, and absence of donor site morbidity are other advantages over autologous breast reconstruction.
