Bone regeneration after pedicled periosteal dorsal metacarpal flap. Reconstructive technique.

The dorsal metacarpal artery (DMCA) flap is considered as one of the working horses to cover exposed extensor tendon or bone of dorsal digits. The periosteal composite DMCA reverse flap (pcDMCAr flap) is described as a fast and safe solution to manage this kind of trauma. A 35-year-old male had a trauma to his left hand from a circular saw. The resultant injury was localized to the proximal middle finger with a dorsal bone loss. A vascularized composite flap, including 3th metacarpal periosteum, was elected as the most appropriate option. Postoperative follow-up at 6 months confirmed bony regeneration. There are no documented cases to the best of our knowledge demonstrating the use of pcDMCAr flap to treat fractures with bone loss in the proximal digits. This report suggests that technique may be employed as regenerative bone flap in reconstructive surgery for proximal fingers trauma with bone loss and open fracture. KEY WORDS: Bone regeneration, Dorsal metacarpal flap, Periosteum.

Inveterated Facial Palsy Correction with Endoscopically Assisted Multiple Muscle Transposition and Lifts: The EMTL Procedure.

Introduction The aim of the present analysis was to study the safety and efficacy associated with reanimation in facial nerve palsy by the endoscopically assisted multiple muscle transposition and lifts (EMTL). Patients and Methods The study sample included all patients who had undergone a facial reanimation by EMTL procedure from September 2015 to May 2019. The patients were analyzed retrospectively, with more than 1 year of follow-up, and were evaluated in terms of functional-aesthetic results and postoperative complications. The outcome was evaluated with the Sunnybrook scale. Results Fourteen patients were included in the present study. They were all inveterate palsies with minimum 4 years from the initial injury. The preoperative Sunnybrook score ranged from 0 to 5 and the postoperative ranged from 30 to 65. Spontaneous smile achievement was obtained in 10 patients and only mild restoration in one patient. The scar and static correction were satisfactory in all patients. Eye protection was improved in all cases with some form of active blinking in six cases. Conclusion This study showed that facial palsy correction with EMTL procedure offers a promising alternative treatment for patients with facial palsy not suitable for microsurgical muscle transposition.

An unusual case of neurothekeoma of the arm in an adult.

Neurothekeomas are uncommon benign neoplasms with a peripheral nerve sheath origin. This tumor usually involves dermis and is described as a small, solitary, slow growing and reddish to flesh-colored nodule or papule. Neurothekeoma preferentially affects the central aspect of the face, the arms or shoulders of women in the second and third decades of life. This is the first case report of neurothekeoma involving the wrist developing from synovial tissue and with uncertain clinical behavior in an adult female. The tumor was completely excised under brachial plexus block. Histopathologically, the examination of the microscopic slides revealed the presence of a 20-mm diameter, well-circumscribed and multilobulated tumor composed of abundant myxoid stroma with cellular elements; with immunohistochemistry there was positivity to vimentin but S100-protein, epithelial membrane antigen, cytokeratin AE1-3, CD99 and CD34 were all negative. This pattern suggested a myxoid tumor form of neurothekeoma, mixed subtype. The patient had an atypical local recurrence and was re-operated after 3 months. After 12 months there was no evidence of clinical recurrences confirmed by magnetic resonance evaluation. Basically, our case report adds an important element in the correct clinical management of neurotecheomas: faced with a histological diagnosis with an unusual localization and mixed or hypercellular type, clinicians must consider the possibility of an early local recurrence, suggesting a close clinical and radiological follow-up.
