Fibrolipomatous hamartoma of the median nerve in a child with carpal tunnel syndrome: imaging findings and literature review.

Fibrolipomatous hamartoma of the median nerve is an uncommon benign tumour of the childhood, which usually manifests in adolescents or adulthood with signs of compressive neuropathy at wrist. Symptomatic tumour is unusual in children below 5 years age and can be underdiagnosed. Magnetic resonance imaging provides pathognomonic features for the diagnosis, obviating the need for biopsy. Although standard ultrasonography is frequently the first-line imaging approach in the evaluation of soft-tissue masses, sonographic findings of this lesion are less frequently reported and have to be kept in mind by radiologist. We report the unusual case of carpal tunnel syndrome secondary to fibrolipomatous hamartoma of the median nerve in a 4-year-old child successfully treated with surgical carpal tunnel release.

The clinical effectiveness of an integrated multidisciplinary evidence-based program to prevent intraoperative pressure injuries in high-risk children undergoing long-duration surgical procedures: A quality improvement study.

The prevention of hospital-acquired pressure injuries (HAPIs) in children undergoing long-duration surgical procedures is of critical importance due to the potential for catastrophic sequelae of these generally preventable injuries for the child and their family. Long-duration surgical procedures in children have the potential to result in high rates of HAPI due to physiological factors and the difficulty or impossibility of repositioning these patients intraoperatively. We developed and implemented a multi-modal, multi-disciplinary translational HAPI prevention quality improvement program at a large European Paediatric University Teaching Hospital. The intervention comprised the establishment of wound prevention teams, modified HAPI risk assessment tools, specific education, and the use of prophylactic dressings and fluidized positioners during long-duration surgical procedures. As part of the evaluation of the effectiveness of the program in reducing intraoperative HAPI, we conducted a prospective cohort study of 200 children undergoing long-duration surgical procedures and compared their outcomes with a matched historical cohort of 200 children who had undergone similar surgery the previous year. The findings demonstrated a reduction in HAPI in the intervention cohort of 80% (p < 0.01) compared to the comparator group when controlling for age, pathology, comorbidity, and surgical duration. We believe that the findings demonstrate that it is possible to significantly decrease HAPI incidence in these highly vulnerable children by using an evidence-based, multi-modal, multidisciplinary HAPI prevention strategy.

Use of acellular intact fish skin grafts in treating acute paediatric wounds during the COVID-19 pandemic: a case series.

OBJECTIVE: More specific strategies are needed to support children requiring skin grafting. Our goal was to identify procedures that reduce operating times, post-operative complications, pain and length of hospital stay. Patient safety, optimal wound bed support and quick micro-debridement with locoregional anaesthesia were prioritised. Ultimately, a novel acellular fish skin graft (FSG) derived from north Atlantic cod was selected for use. METHOD: We admitted consecutive paediatric patients with various lesions requiring skin grafting for definitive wound closure. All FSGs were applied and bolstered in the operating room following debridement. RESULTS: In a cohort of 15 patients, the average age was 8 years and 9 months (4 years 1 month-13 years 5 months). Negative pressure wound therapy (NPWT) was given to 12 patients. Rapid wound healing was observed in all patients, with a wound area coverage of 100% and complete healing in 95% of wounds. Time until engraftment in patients receiving NPWT was reduced by about a half (to an average 12 days) from our standard experience of 21 days. Ten patients received locoregional anaesthesia and were discharged after day surgery. The operating time was <60 minutes, and no complications or allergic reactions were reported. Excellent pliability of the healed wound was achieved in all patients, without signs of itching and scratching in the postoperative period. This case series is the first and largest using FSG to treat paediatric patients with different wound aetiologies. We attribute the rapid transition to acute wound status and the good pliability of the new epidermal-dermal complex to the preserved molecular components of the FSG, including omega-3. CONCLUSION: FSG represents an innovative and sustainable solution for paediatric wound care that results in shorter surgery time and reduced hospital stays, with accelerated wound healing times.

Case report of anesthesia for free fibula flap reconstruction in Ewing sarcoma: Safety and efficacy of continuous popliteal sciatic nerve block and very low doses of intravenous heparin.

A child with a maxillary Ewing sarcoma was operated for tumor asportation and reconstruction with free fibula flap. Adequate anticoagulation was achieved with lower doses of heparin and monitored with multiple ACT values. We used NIRS monitoring to avoid hypoperfusion. Post-operative pain relief was guarantited by local anestethic continous infusion.

The Versatility of the Free Vastus Lateralis Muscle Flap: Orbital Reconstruction After Removal of Complex Vascular Malformation in a Pediatric Patient.

Introduction: Vascular orbital lesions in pediatric population represent a demanding therapeutic challenge which requires a multidisciplinary team. In severe cases, orbital enucleation can be considered. Surgical management of enucleated orbital region in children, differently from the adults, represents a challenging procedure owing to the intrinsic relation between volume replacement and normal orbital growth. Many reconstructive options have been proposed, and many donor sites have been utilized for this purpose but each one have demonstrated potential disadvantages. Despite its well-known versatility, no report of the vastus lateralis free flap in children requiring orbital reconstruction exists in literature. Herein, we propose this surgical strategy as a valid option for the reconstruction of an extended orbital defect in a pediatric patient suffering from a mixed type of vascular malformation. Material and Methods: A patient was referred from a foreign country with an unclear medical history, presenting exorbitism and exophthalmos, proptosis of the eyeball, visus 4/10, and limited ocular motility. We made clinical-instrumental investigations with a diagnosis of complex vascular malformation. It expanded in intraorbital and retrorbital space with bulb anterior dislocation and optic nerve involvement. We performed an emptying of the orbital content via transconjunctival and via coronal incision with eyelid preservation. A free vastus lateralis muscle flap was used for reconstruction, filling the orbital cavity. We anastomosed the flap on the superficial temporal artery. An ocular conformator was then positioned. Results: We report the result at 12 months, showing a good orbital rehabilitation with an adequate prosthetic cavity, a good recovery of volume and facial symmetry, guaranteeing balanced orbital and periorbital growth. There were no major or minor complications associated with the procedure. Discussion: The reconstruction of the orbit remains a "surgical challenge" both in adults, whose goal is the restoration of volume, adequate symmetry and facial esthetics, and children, in which correcting the asymmetry has the additional objective to balance orbital growth. Many reconstructive techniques have been proposed, including the use of free flaps. The versatility of the free vastus lateralis muscle flap is well-known. It offers adequate amount of tissue with minimal morbidity to the donor site, provides a long pedicle, gives the possibility of simultaneous work in a double team, and has a constant anatomy and a safe and rapid dissection. There are no descriptions of its use for pediatric orbital reconstructions. Conclusions: In our opinion, the free vastus lateralis flap should be included as one of the best option for orbital pediatric reconstruction after enucleation.

Anterior retrograde approach to the myofascial temporalis muscle for orbital reconstruction: series of 9 consecutive cases.

BACKGROUND: Among the reconstructive options after orbital exenteration, the temporalis myofascial flap (TMF) has been widely recognized as the one of the best available solutions. We think that the hemicoronal approach to harvest the TMF represents a disadvantage so we adopted a modified approach that we named the anterior retrograde approach to the TMF. METHODS: Nine patients with malignant orbital tumors underwent orbital exenteration and primary reconstruction with TMF harvested with the anterior retrograde approach. The temporalis muscle was widely exposed through the anterior incision used to perform the orbital exenteration. The harvested flap was then rotated and insetted to fill the orbital cavity. RESULTS: Neither cases of total/partial flap failure nor local/regional recurrence of tumor were recorded. The technique showed a significant reduction of morbidity, surgical time, and blood loss compared with the traditional technique. CONCLUSIONS: We think that the anterior retrograde approach should be considered as a valid alternative to the traditional hemicoronal approach.

Equine pericardium membrane to prevent dorsal irregularities in rhinoplasty.

Even after a well-executed rhinoplasty, small dorsal irregularities are not uncommon. Many materials have been used for camouflage, including autologous, homologous, and alloplastic materials. We used an equine pericardium membrane in 33 postrhinoplasty patients to prevent or correct nasal dorsal irregularities. The membrane promotes a local fibrous reaction, which leaves a uniform connective layer. In our hands, equine pericardium membrane seems to be a useful material for rhinoplasty refinements.

Autologous fat transplantation for the temporalis muscle flap donor site: our experience with 45 cases.

BACKGROUND: Temporal depression after temporalis muscle flap transposition is characterized by a concavity of the soft tissue and associated with the relief of the orbital rim and zygomatic arch. The purpose of this study was to describe the use of autologous fat grafting for the treatment of postsurgical temporal contour deformities. METHODS: Between March 2008 and April 2011, 45 patients were treated with lipofilling. A virtual 3-dimensional preoperative assessment was used to objectively quantify the loss of volume of the affected side. Two different methods were used to evaluate the surgical outcomes. RESULTS: A noticeable soft tissue augmentation of the temporal region was noted in all cases. In 35 patients, a second procedure was required and in 1 patient, a third procedure was required. The final result was assessed as fully satisfactory by 39 patients (86.6%), as satisfactory by 5 patients (11.1%), and as unsatisfactory by 1 patient (2.2%). CONCLUSION: We believe that structural fat grafting at the temporalis muscle flap donor site is an effective technique that provides a high satisfaction rate and only a few complications.

Giant neglected desmoplastic ameloblastoma: reconstruction with free fibula flap.

The desmoplastic ameloblastoma (DA) is a rare variant of the conventional ameloblastoma. It accounts for only 4% to 13% of all ameloblastomas. In this article, we describe the case of a young child affected by a giant neglected DA of the jaw. Preoperative biopsy demonstrated the extremely rare osteoplastic variant of DA. The patient was submitted to segmental mandibulectomy and immediate reconstruction with a free fibula osseous flap. The postoperative period was uneventful. The patient was very satisfied with the functional and aesthetic results of the procedure. In case of such rare variants of ameloblastoma, it is mandatory to preoperatively recognize them to allow the adequate treatment modality to be provided.

Retrobulbar lipofilling to correct the enophthalmos.

In this article, we describe an alternative procedure to restore the retrobulbar volume in enophthalmic patients. We report the case of a patient with a late enophthalmos we submitted to retrobulbar lipofilling to correct the defect. The preoperative assessment and the surgical technique are described in detail. The volume of fat injected was 3.2 mL, with a satisfying increase in exophthalmometry measurements. The procedure was well tolerated without complications. Retrobulbar lipofilling for enophthalmos appears to be a safe alternative technique for orbital volume enhancement. It avoids the use of alloplastic materials and allows to obtain good cosmetic results with an easy technique and minimal donor-site morbidity.
