"DO ONE, GET TWO": dual venous drainage of the radial forearm free flap by a single venous anastomosis.

PURPOSE: The radial forearm free flap (RFFF) remains a workhorse in microsurgical reconstruction. Its failure is primarily due to problems with venous drainage; for this reason, controversy on venous anastomosis patterns still exists. This manuscript describes our experience in using a communicating vein to overcome the complications of venous drainage of the RFFF. METHODS: Following a review of the vascular anatomy of the RFFF, we retrospectively review the use of the communicating vein and report our results, with the aim of overcoming the dichotomy "superficial versus deep venous system" and "single versus double anastomosis" and discussing the evidence of advantages in using a single microanastomosis with a communicating vein. RESULTS: Our retrospective review included a total of 123 patients in which a RFFF was performed to reconstruct intraoral defects, performed with a single venous anastomosis using the communicating vein. Four patients (3.25%) required a return to theatre for revision of the venous anastomosis and one case resulted in flap failure due to arterial insufficiency (0.81%). CONCLUSIONS: Our series highlights the constant presence of the communicating vein, although with variations of origin and course that did not preclude the possibility to correctly perform the anastomosis. Advantages of a single microanastomosis with the communicating vein include ease, speed, reliability and versatility in planning the anastomosis. Based on our results, the use of the communicating vein showed comparable and, in some cases, more favourable results when compared to venous anastomotic complications reported in the literature.

Outcomes of a Mini External Fixator System for the Treatment of Unstable Periphyseal Hand Fractures.

Background: Most unstable hand fractures in children are treated by closed methods. If osteosynthesis is required, Kirschner (K)-wires are commonly used, though they carry a risk of injury to the physis. We have been using a mini external fixator system (MEFS) for the treatment of unstable periphyseal fractures of the hand. The aim of this study is to describe the application and report the outcomes of MEFS for the treatment of periphyseal fractures of the hand. Methods: We retrospectively reviewed all the patients with periphyseal fracture of the hand treated with MEFS from March 2010 to December 2019. Data with regard to age, sex, hand dominance, digit and bone injured, mechanism of injury, medical records and related radiographs were collected. Salter-Harris classification was used to classify epiphyseal fractures and the Al-Qattan classification for categorising neck fractures. Range of motion and residual deformity of the affected fingers were evaluated during follow-up and at 3 months postoperatively. Results: Fourteen periphyseal unstable fractures were treated using closed reduction and MEFS. Only one patient with a fracture of the neck of the proximal phalanx of the little finger required revision surgery. No patient had pin site infection or pin loosening and the device was well tolerated by all patients. All fractures united and all the patients recovered a full range of motion at final follow-up. Conclusions: The MEFS is a reasonable alternative for unstable periphyseal fractures with good outcomes and avoids the risk of iatrogenic physeal injury from K-wire fixation. Level of Evidence: Level IV (Therapeutic).

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.

Role of systematic scalp expansion before cranioplasty in patients with craniectomy defects.

PURPOSE: Scalp management is challenging in all types of cranioplasties, particularly following decompression or in case of resorption of a repositioned bone flap. In these cases, reduction of brain volume is constantly associated with tightening of the skin cover. MATERIAL AND METHODS: A retrospective analysis of 36 cranioplasties was performed. All patients showed cranial decompression or a large craniectomy. In all cases, cranioplasty was preceded by a preliminary scalp expansion. RESULTS: Two patients had expander exposure. One of them underwent re-intervention, to reposition the implant. Complications of the cranioplasty phase were one case of extradural hematoma, five cases of swelling due to liquorrea, four cases of temporary forehead edema, and one case of temporal bulging due to the implant. Cranial decompression and other craniectomy procedures often produce a tightening of the scalp, which makes the cranioplasty problematic. The preliminary systematic scalp expansion performed in all patients resulted in a convenient skin excess that allowed a tension-less closure, preventing the scalp suture from falling right on the edge of the cranioplasty implant. CONCLUSION: A systematic preliminary scalp expansion allows one to minimize cranioplasty complications in patients with craniectomies, to anticipate possible necrotic scalp complications in the expansion phase rather than in the cranioplasty phase, and thereby avoid implant loss.

Surgical management of digital calcinosis in CREST syndrome.

As a limited form of sclerodermy, CREST syndrome is characterized by calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia, which determine the acronym CREST. Calcinosis is a particularly difficult entity to treat given the paucity of effective options described in the literature. Treatment of finger calcinosis has a wide range of possibilities depending on the extent of calcifications and the involvement of deep structures. From a surgical point of view, whereas simple removal is adequate in minor outpatient cases, a radical debridement in the major and more painful cases seems required. A cover flap is needed particularly in the thumb due to its great functional importance, also if the fingertip is not involved. The authors recommend the kite flap for the dimensions, the tissue quality, and the possibility of giving sensation to the reconstructed area. With this surgical option, the transferred skin is soft, sensate, and the right fit. Usually, no further operations are needed for flap remodeling. The time required for sensory integration is about 2 years, often related to the age of the patient. Debridement and flap reconstruction usually give total resolution of pain, with complete recovery of thumb motion and the thumb-index finger grip.
