Phenytoin Induced Purple Glove Syndrome: An Effective Management Technique.

Background: Purple glove syndrome (PGS) is a rare condition characterized by limb edema, discoloration, and pain associated with intravenous and oral phenytoin administration. The pathophysiology is poorly understood, and there is no established treatment. Simple cases have previously been managed with hyaluronidase subcutaneous injections, with more severe cases resulting in compartment syndrome, debridement, or even amputation. Methods/Results: In this case report, a 2-year-old boy with status epilepticus developed PGS after receiving intravenous phenytoin via a cannula on the dorsum of the right hand. The patient was successfully managed by locally infiltrating subcutaneous hyaluronidase diffusely to the affected area, titrating its dose to effect, rather than aiming to adhere to any specific dosing limitation. The child was reviewed daily by the Plastic Surgery team until being discharged, and focal lesions began to demarcate after 48 hours, with epidermal loss but no deeper trauma. The epidermis peeled within one month, with healthy underlying skin found underlying when followed up in clinic. Conclusions: This case illustrates that subcutaneous administration of hyaluronidase and titrating to effect provides an effective and safe treatment for treating distal cases of early PGS in children.

Outcomes in facial transplantation - A systematic review.

Facial transplantations have become a clinical reality as the last reconstructive option in severely disfigured patients. To date, clinical outcomes remain unclear. The purpose of this paper was to analyse the outcomes in facial transplantation (FT) and determine the risks and benefits of FT based on short- and long-term outcomes. An electronic literature search was performed across PubMed, EMBASE and the Cochrane Central Register for Controlled Trials (CENTRAL) databases to capture all the relevant records relating to outcomes in FTs from 2005 to 2021. Articles for inclusion were decided upon pre-defined inclusion and exclusion criteria. A total of 48 FTs has been performed to date. A total of 90 studies met the eligibility criteria and were included in the outcome analysis. Studies were analysed based on each of the 48 cases and outcomes categorised into short-term (<36 months) and long-term (>36 months) outcomes. Primary outcomes included patient and graft survival and secondary outcomes included functional, surgical revision events, immunological, medical complications, aesthetics, psychosocial and quality of life. Mortality rate, infection and malignancy incidence remain high, and patients should be fully informed of the potential life-threatening complications. FTs improve outcomes such as quality of life and psychosocial recovery in the short- and long-term. Outcomes remain under-reported in peer-review journals.

Four-Layer Wound Closure Technique with Barbed Sutures for Inframammary Fold in Mastopexy Augmentation.

BACKGROUND: The inframammary fold (IMF) is an important landmark in breast aesthetic surgery. In augmentation mastopexy procedures, secure and accurate placement of the IMF is essential to aesthetic outcomes and to allow the new IMF to heal in the correct position without displacement. The authors present a simple and efficient four-layer wound closure technique using barbed sutures for closure of the repositioned IMF in augmentation mastopexy procedures. This method was previously described by the first author for reset of the IMF in breast augmentation surgery and has been adapted to the longer IMF incision in augmentation mastopexy procedures. METHODS: A retrospective review was undertaken of 335 patients who underwent bilateral breast augmentation mastopexy procedures with a Wise pattern technique at a single unit. The newly reset IMF was closed using barbed sutures and a four-layer closure technique. RESULTS: There were no cases of complications related to wound healing or wound dehiscence. One patient required explantation for an infected implant. CONCLUSION: The four-layer wound closure technique with barbed sutures provides a quick and efficient method for accurate closure of the newly reset IMF, with positive outcomes related to wound healing. Secure and accurate placement of the inframammary fold is crucial in augmentation mastopexy procedures. The use of a four-layer wound closure technique with barbed sutures provides an efficient method for accurate closure of the newly reset inframammary fold. This method was previously described by the first author for reset of the IMF in breast augmentation surgery and has been adapted to the longer IMF incision in augmentation mastopexy procedures.

Pharmacological interventions for early-stage frozen shoulder: a systematic review and network meta-analysis.

OBJECTIVES: To evaluate the efficacy of pharmacological interventions for treating early-stage, pain predominant, adhesive capsulitis, also known as frozen shoulder. METHODS: We performed a systematic review in accordance with PRSIMA guidelines. Searches were conducted on PUBMED, EMBASE and Cochrane Central Register of Controlled Trials on the 24th of February 2022. Outcomes were shoulder pain, shoulder function and range of movement. Synthesis involved both qualitative analysis for all studies and pairwise meta-analyses followed by a network meta-analysis for randomised controlled trials (RCTs). RESULTS: A total of 3,252 articles were found, of which 31 met inclusion criteria, and 22 of these were RCTs. Intraarticular (IA) injection of corticosteroids (8 RCTS, 340 participants) and IA injection of platelet-rich plasma (PRP) (3 RCTs, 177 participants) showed benefit at 12 weeks compared with physical therapy in terms of shoulder pain and function, while oral non-steroidal anti-inflammatories (NSAIDs) (2 RCTs, 44 participants) and IA injection of hyaluronate (2 RCTs, 42 participants) did not show a benefit. Only IA PRP showed benefit over physical therapy for shoulder range of movement. CONCLUSION: These results shows that IA corticosteroids IA PRP injections are beneficial for early-stage frozen shoulder. These findings should be appraised with care considering the risk of bias, heterogeneity, and inconsistency of the included studies. We believe that research focused on early interventions for frozen shoulder could improve patient outcomes and lead to cost-savings derived from avoiding long-term disability. Further well-designed studies comparing with standardised physical therapy or placebo are required to improve evidence to guide management.

Osteocutaneous Turn-Up Fillet Flaps: A Spare-Parts Orthoplastic Surgery Option for a Functional Posttraumatic Below-Knee Amputation.

This article portrays the authors' experience with a complex lower limb bone and soft tissue defect, following chronic osteomyelitis and pathological fracture, which was managed by the multidisciplinary orthoplastic team. The decision for functional amputation versus limb salvage was deemed necessary, enhanced by the principles of "spare parts" in reconstructive microsurgery. This case describes the successful use of the osteocutaneous distal tibia turn-up fillet flap that allowed "lowering the level of the amputation" from a through knee to a below-knee amputation (BKA) to preserve the knee joint function. We comprehensibly review reports of turn-up flaps which effectively lower the level of amputation, also applying "spare-parts" surgery principles and explore how these concepts refine complex orthoplastic approaches when limb salvage is not possible to enhance function. The osteocutaneous distal tibia turn-up fillet flap is a robust technique for modified BKA reconstructions that provides sufficient bone length to achieve a tough, sensate stump and functional knee joint.

Silicone Migration From Breast Implants: A Case of Ocular Siliconoma and Literature Review.

BACKGROUND: Breast augmentation with implants is one of the most popular cosmetic surgery operations performed worldwide. Complications of breast implants are well recognized, and include capsular contracture, implant rupture, and infrequently distant migration of silicone, resulting in siliconoma. Distant migration of silicone can present many years after implantation with a wide variety of signs and symptoms. OBJECTIVES: The aim of this study was to describe the authors' experience of orbital silicone migration and to review the literature describing documented cases of distant silicon migration from breast implants, both ocular and nonocular. METHODS: In January 2022, a case of breast implant augmentation presented with silicone migration into the right orbit. This rare case was monitored and diagnosed with ocular muscle palsy and diplopia. Here, the authors present the patient's presenting complaint, symptomatology, working investigations, and outcomes. A comprehensive report of all available cases of distant silicone migration is presented along with their associated complications and more specifically ocular silicone migration. RESULTS: Systemic migration of silicone from breast implants to the orbital region is extremely rare: a total of 4 previous cases of ocular silicone migration from breast implants have been described previously; the authors describe the fifth case herein. CONCLUSIONS: Silicone implant rupture can present with a wide variety of clinical symptoms that may mimic different clinical pathologies. In every patient with a history of breast augmentation with silicone implants, the possibility of silicone migration should be always taken into consideration during the differential diagnosis process.

Anatomical Variations of the Pectoralis Muscle and Its Importance for Breast Implant Surgery.

In breast augmentation, during submuscular or dual plane dissection, anatomical variations of the inferior and costal origin of the pectoralis major muscle (PMM) play a key role to ensure optimal implant coverage. Especially, a short and narrow muscle or surgical release along the sternum increases the risk of irregularities and animation deformities of the implant. Methods: In 84 consecutive aesthetic breast augmentations intraoperatively, measurement of PMM dimensions was performed bilaterally. These PMM measurements were then correlated with the preoperative breast width, the inframammary fold, and the placement of the implant's lower pole. Results: One hundred sixty-eight PMMs of 84 patients were dissected with a dual plane II or III technique for primary aesthetic breast augmentation. In 88% of breasts, the calculated implants' lower pole was below the inferiomedial origin of the pectoralis muscle. In 10% of patients, a separation (more than 1 cm wide and 2 cm wide) in the inferior-medial origin of the PMM was noted. An asymmetry more than 0.5 cm in length between the left and right pectoralis major was noted in 36% of patients. Conclusions: In this series, the anatomy of the PMM demonstrates a substantial variability in width and length and a considerable asymmetry in its dimensions. These findings emphasize the importance of good access and visualization of the origin of the PMM fibers before its division.

The tale of the "unlucky" 13 errors in the "journey" towards an outstanding end -product in microvascular anastomosis training.

In microsurgery training, where the first steps occur in a safe simulated environment, we believe there is a lack of emphasis on well reflected commonly occurring mistakes; education manuals provide stepwise instructions on performing tasks but do not list common mistakes and ways to avoid them. It is well acknowledged that the majority of vascular anastomotic complications are attributed to technical errors, however the validated global rating scales that are used to assess microsurgical competency do not address errors and how to avoid making them - potentially preventing devastating failures. Our aim is to improve and streamline constructive feedback in microsurgical education by use of an error-based learning resource. By referring to our '13 errors' graphic, teachers and students can refer to specific errors they have made, and quickly revise these with error-specific feedback, with and without supervision. The '13 errors' table enables identification errors, explanation as to why these may have occurred, and constructive feedback in order to rectify the mistake.

The Role of Measurement of Pedicle Length for DIEP Flap Transferring in Breast Reconstruction: A Single-Center, Open-Label, Randomized Controlled Trial.

BACKGROUND: Intraoperative venous congestion is a main complication in deep inferior epigastric artery perforator (DIEP) flap for breast reconstruction. We present a pedicle measuring technique to precisely predict the length of pedicle needed in DIEP free flap, to improve the outcome, and to reduce the risk of donor site morbidity and complications. MATERIALS AND METHODS: A single-center, open-label, prospective, randomized study was carried out to access efficacy and safety of a pedicle measuring technique in 389 patients. Each patient received a delayed breast reconstruction using free unipedicled DIEP flap, and internal mammary vessels were chosen as recipient vessels. During the surgery, the conventional DIEP flap technique was used in the control group, in which the course of the pedicle was fully dissected. In the measuring group, the flap in setting way was decided preoperatively, the distance (A) between the internal mammary vessels (a) and the point of DIEP perforator into the subcutaneous tissue (b) was measured, and then the length (B) of the perforator (c) and the main trunk (d) is measured and dissected to achieve 1 cm longer than A. RESULTS: There are 180 and 209 patients enrolled in the control and measuring group, respectively. Venous congestion occurred in 15 patients (8.3%) in the control group, and 1 patient (0.5%) in the measuring group ( P < 0.001). All the 16 patients were found venous thrombosis. Then successful free flap salvage surgeries were performed in 10 patients. Six patients (3.3%) had total flap necrosis due to recurrent venous thromboembolisms. Fat necrosis occurred in 16 patients (8.9%) in the control group, and 5 patients (2.4%) in the measuring group ( P = 0.006). Partial flap necrosis was found in 12 patients (6.7%) in the control group, and in 3 patients (1.4%) in the measuring group ( P = 0.008). Total flap necrosis occurred in 6 patients (3.3%) in the control group, but no (0%) patient in the measuring group ( P = 0.009). CONCLUSIONS: Measurement of pedicle length for DIEP flap transferring in breast reconstruction is a reliable technique that could secure the DIEP free flap, reduce operative invasiveness, and lower the risk of complications considerably.

The "Domino Flaps" Concept: Functional Composite Reconstruction for Traumatic Transmetacarpal Thumb Amputation.

Complex transmetacarpal thumb amputation remains a challenging reconstructive injury. Optimal reconstructive options aim to achieve a neo-thumb with optimal length, sensitivity, stability, and an aesthetically functional result. In cases when immediate replantation of the amputated digit is not possible, a temporary ectopic replantation with staged reconstruction can be deployed. We report our experience of a complex transmetacarpal thumb amputation managed with a staged "domino flap" concept. The first stage involved an ectopic replantation of the amputated digit with a second stage replantation 3 weeks later. Domino flap refers to the requirement of a further reconstruction due to the defect at the donor sites. In this case, the replant is accompanied by 2 domino flap reconstructions with the dorsalis pedis composite free flap to reconstruct the first metatarsal and an anterior tibial artery propeller perforator flap to reconstruct the composite flap donor site.

Microtools: A systematic review of validated assessment tools in microsurgery.

BACKGROUND: Microsurgery is a technically demanding aspect of surgery that is integral to a variety of sub-specialties. Microsurgery is required in high-risk cases where time is limited and pressure is high, so there is increasing demand for skills acquisition beforehand. The aim of this review was to analyse the available literature on validated microsurgical assessment tools. METHODS: Covidence was used to screen papers for inclusion. Keywords included 'microsurgery', 'simulation', 'end-product assessment' and 'competence'. Inclusion criteria specified simulation models which demonstrate training and assessment of skill acquisition simultaneously. Tools which were used for training independently of technical assessment were excluded and so were tools which did not include a microvascular anastomosis. Each assessment tool was evaluated for validity, bias, complexity and fidelity and reliability using PRISMA and SWiM guidelines. RESULTS: Thirteen distinct tools were validated for use in microsurgical assessment. These can be divided into overall assessment and end-product assessment. Ten tools assessed the 'journey' of the operation, and three tools were specifically end-product assessments. All tools achieved construct validity. Criterion validity was only assessed for the UWOMSA1 and GRS.2 Interrater reliability was demonstrated for each tool except the ISSLA3 and SAMS.4 Four of the tools addressed demonstrate predictive validity.4-7 CONCLUSION: Thirteen assessment tools achieve variable validity for use in microsurgery. Interrater reliability is demonstrated for 11 of the 13 tools. The GRS and UWOMSA achieve intrarater reliability. The End Product Intimal Assessment tool and the Imperial College of Surgical Assessment device were valid tools for objective assessment of microsurgical skill.

Single-stage buried autologous breast reconstruction (BABR).

BACKGROUND: Breast reconstructive standards are increasingly high oncologically, aesthetically, and practically. Autologous breast reconstruction remains the gold standard which, buried, after nipple-sparing mastectomy (where oncologically safe) or wise pattern reduction for large or ptotic patients, with contralateral symmetrisation where required, enables single-stage reconstruction. However, previous series report prohibitively high revision rates. This series prospectively compares a series of buried and non-buried free flaps for breast reconstruction. METHODS: All breast reconstructions with free autologous tissue transfer, buried or with a cutaneous paddle, conducted over 8 years by a single surgeon were included. Demographic, oncologic and reconstructive details, immediate complications and revision surgeries were recorded and compared between the two groups. RESULTS: A total of 182 free flaps were performed on 156 patients, 69 buried and 113 with cutaneous paddles. There were no significant demographic or complication differences between the two groups. Of the buried group, 51% did not require further surgery compared to 29% of the paddle group. CONCLUSIONS: Buried autologous breast reconstruction is a safe and aesthetic option for breast reconstruction, and potentially single stage. This is particularly true where it is combined with nipple-sparing mastectomy (where oncologically safe) or breast reduction mastectomy, and contralateral symmetrisation, where required. Further research could include patient reported outcome measures and cost analysis.

The impact of parity in primary breast augmentation: A clinical and cost-effective case control study.

INTRODUCTION: Breast augmentation is one of the most commonly performed aesthetic procedures in women. Despite the structural changes which occur during pregnancy and lactation have been extensively studied, there is no clarity in terms of the time required for the parenchymal angiogenic changes to regress or if these neovessels are preserved even years after the last lactating period. This study investigated whether these post-pregnancy structural changes on the breasts may influence the surgical efficiency, affect the rates of complications and have an impact on cost-effectiveness in primary breast augmentation. METHODS: This study encompasses a retrospective review of all patients who underwent implant-based bilateral primary breast augmentation, through inframammary fold (IMF) incision under general anaesthetic, by a single surgeon. The age, height, weight and parity (nulliparous or multiparous status), characteristics of implants used and clinical outcomes after a minimum of 6-month post-operative follow-up were recorded. A further prospective comparative trial investigated the effects of parity in the surgical efficiency and cost-effectiveness in primary breast augmentation. The surgical efficiency (total operative time) and the immediate complications of 85 consecutive cohort of patients were recorded by an independent observer. Statistical correlation investigated the relevance of parity as predictors of surgical efficiency and cost-effectiveness. RESULTS: A total of 894 patients were included with a minimum of 6-month follow-up following implants-based primary breast augmentation. There were 445 (49.8%) nulliparous and 449 (50.2%) patients had at least one child at the time of surgery. The average parity index was calculated to be 1.05. The average body mass index (BMI) was 20.8 kg/m2 (15.9-30.8). The mean implant volume used was 314 ml. Fifteen percent (n = 134) presented with post-operative complications, with an average follow-up period of 12.8 (6-116) months. The differences between parity and incidence of complications were not statistically significant (p = 0.82). Surgical efficiency parameters from 85 women (54 multiparous and 31 nulliparous) demonstrated total operative time difference; 35 ± 6.3 min for multiparous and 30.2 ± 5 min for nulliparous. There was a clinical average difference of 4.8 min, with a maximum difference of 16.1 min. These statistically significant difference account for an average increase of 13.7% in the operating time in multiparous versus nulliparous (p-value=0.0004, 95% CI = 2.2-7.4 min). CONCLUSION: Primary breast augmentation in parous women faces parenchymal and vascular histological breast tissue transformations which may not fully revert to the pre-pregnant state. These changes encountered during pocket dissection seem to have an impact on the operating time, cost-effectiveness and can therefore affect negatively surgical efficiency. Nevertheless, when surgical technique is based on sharp, precise dissection and proactive haemostasis, parity does not show to have an impact on the rates of complications, despite longer operation times.

Multi-pedicled long fasciocutaneous free flaps in complex lower extremity reconstruction.

Fasciocutaneous free tissue transfer is an established limb salvage modality in lower extremity reconstruction. In severe cases, defect coverage is challenging due to the size and extent of the injury which may surpass the dimensions of most commonly utilized fasciocutaneous donor sites. This is further complicated by the considerable length between the recipient pedicle and most distal segment of the defect requiring coverage. Available donor sites that are able to provide free fasciocutaneous flaps extended length (>40 cm) are combinations between the lateral thoracic, lower abdomen/groin and lateral thigh regions. Advantages of this include a single donor site that can be closed primarily, the ability to utilize healthy vessels outside the zone of trauma/injury for microvascular anastomosis and single stage reconstruction. In addition, from a logistical perspective, single flap harvest would theoretically be more efficient and less resource intensive than harvesting two separate flaps or performing large skin grafts. Herein, we present current available donor sites that allow harvest of long fasciocutaneous free flaps incorporating multiple pedicles with a single skin paddle for lower extremity reconstruction.

Bilateral Anterolateral Thigh Myocutaneous Flaps for Giant Complex Chest Wall Reconstruction.

BACKGROUND: Extensive reconstruction of complex full-thickness chest wall oncological defects is challenging. Bilateral free anterolateral thigh (ALT) myocutaneous flap transfer for the complex reconstruction of a large area of the chest wall is discussed. MATERIALS AND METHODS: We reported a single unit's experience in 1-staged multilayered reconstruction of large full-thickness chest wall defects in 22 patients (16 primary chest wall tumor cases, 5 locally advanced breast cancer cases, and 1 osteoradionecrosis case) treated between 2011 and 2018. Bilateral ALT myocutaneous flaps together with traditional cement implant or unmovable/movable joint conformable titanium struts were used for chest wall reconstruction. The anatomical characteristics of pedicle origin and pattern of the venae comitantes of the ALT myocutaneous flap, recipient vessels, and anastomosis patterns were described. RESULTS: Bilateral ALT myocutaneous flaps were used for soft tissue reconstruction in 22 cases. Different methods of flap harvesting and vascular anastomosis were selected as needed. No vein grafts or arteriovenous loops were required. We observed 3 vascular patterns of the flap pedicle, including 1 oblique branch and descending branch (59.1%, n = 26), 2 single descending branch (9.1%, n = 4), and 3 double branches of the descending branch (31.8%, n = 14). The flap was harvested pedicled with solely the oblique branch in 7 (15.9%) cases, solely the descending branch in 28 (63.6%) cases to minimize the donor site morbidity, and pedicled with the oblique and descending branch in 9 (20.5%) cases to achieve multiple vascular anastomosis choices. Stable skeletal reconstructions were achieved using traditional cement implant (13.6%, n = 3) or conformable titanium struts (86.4%, n = 19), with good fixation strength. Complication risk was low. An algorithmic approach to management is presented and recommended. CONCLUSION: Various forms of bilateral ALT myocutaneous flap transfer with different skeletal reconstruction presents as a reliable treatment for patients with large full-thickness chest wall defects. Anatomical variations in the pedicle and pattern of venae comitantes of the ALT myocutaneous flap are reported. In some challenging cases, finding the vessels in the recipient area is difficult. The clinical significance of each vascular pattern is delineated, and surgical technical considerations are discussed on the basis of the recipient area requirements and types of a flap's vascular anatomy.

The effect of implant surface on the recurrence rates of capsular contracture following revision breast surgery: Early results from a single surgeon retrospective comparative study.

INTRODUCTION: This retrospective comparative study aimed to evaluate the effect of implant surface in two cohorts of consecutive patients who underwent revision surgery following capsular contracture (Baker III-IV) after primary breast augmentation with textured implants. METHODS: All patients underwent the same surgical procedure (capsulectomy - pocket plane change - implant exchange) and the only difference was that two different types of implants were used during the implant exchange: textured(Group A - biocell) or nanotextured(Group B - silksurface). A comparative analysis was performed using the following parameters: patients' demographics, age, the time between the primary breast augmentation and the revision surgery, the surgical and follow-up outcomes; and the incidence, timing, and capsular contracture recurrence. RESULTS: Eighty consecutive females were included, Group A(textured): age of 35(19-65) years and time between primary and secondary surgery of 59(6-209) months; and Group B(nanotextured): age of 39(26-58) years and time between primary and secondary surgery of 65(7-218) months. For both groups, at a mean follow-up of 25(21-36) months for Group A(textured), and at a mean follow-up of 24(21-34) months for Group B(nanotextured); capsular contracture reoccurred in 3 cases (7.5%), at 7, 10, and 14 months in Group A and in 3 cases (7,5%), at 9, 10, and 16 months in Group B, post revision surgery. Students' t-test demonstrated no statistically significant differences between the recurrences of the two implant surfaces (p-value>0.05). CONCLUSION: In capsular contracture revision surgery, the type of implant surface (textured or nanotextured) does not appear to influence recurrence rates. Further studies are required to identify the clinical impact on the implant surface in long-term outcomes of capsular contracture breast surgery.
