The New Transverse-Facial Artery Musculomucosal Flap for Intraoral Reconstructions

Head/neck cancer resections often require reconstruction to restore form and function. Small-to-medium size intraoral defects can be successfully reconstructed by local pedicled flaps, such as the facial artery musculomucosal (FAMM) flap,1 which encompasses different layers: cheek mucosa and submucosa, the underlying layer of the buccinator muscle, a portion of the orbicularis oris close to the labial commissure, and the facial artery.2 The flap is usually outlined longitudinally over the facial artery course, and average size is 5 × 2.5 cm. We describe here an innovative flap design and dissection, apt to treat larger defects than the usual ones. Go to: METHODS In a 50-year-old patient with squamous carcinoma of the soft palate involving also surrounding oral soft tissue, after oncological resection, we designed on the cheek mucosa an 8 × 3 cm flap with a squamous carcinoma orientation. The flap axis was crossing about 90 degrees the projection of the facial vessels. Dissection was carried out in anteroposterior direction and the facial artery skeletonized in continuity 3.5 cm superiorly and inferiorly the flap entrance (Fig. ​(Fig.1).1). Once the vascular pedicles had been mobilized and the labial artery ligated, the transverse (t)-FAMM flap was transposed superoposteriorly and sutured to the residual mucosa of the hard palate. A contralateral t-FAMM flap was harvested and transposed. The whole soft palate was then reconstructed by suturing the 2 flaps together

Tattooing of the nipple-areola complex: What not to do. A case series

Introduction: Reconstruction of the nipple areola complex (NAC) is the final and easier step of breast reconstruction. However, surgeons, especially if trainees, typically have not developed tattoo skills during their training. The aim of this report is to share advice developed in our clinical practice that would minimize patient complaints and complications while performing NAC tattoos. Methods: From January 2016 to May 2018, reconstruction of NAC was performed in 48 consecutive patients. Nipple reconstruction was performed initially using skin flaps and this was followed three to eight months later by NAC tattooing. We analyzed medical reports at 12 months follow-up where we usually record patient satisfaction (very satisfied, satisfied, dissatisfied) and every patient's complaint or complication. Results: Thirty-two patients (67%) were very satisfied of NAC tattooing, twelve patients (25%) satisfied, while four patients (8%) dissatisfied. Patients complained for not having involved in choosing color, areas without sufficient pigment, extreme darkness of the tattooed NAC and artificial look. Conclusion: Tattooing is a simple and safe procedure, with a high satisfaction rate. Based on our experience, despite some technical aspects have to be considered, it is a procedure that can be safely performed by plastic surgical trainees

Nilotinib: a novel encouraging therapeutic option for chronic myeloid leukemia patients with imatinib resistance or intolerance

Although high rates of complete hematologic and cytogenetic remission have been observed in patients with chronic phase chronic myeloid leukemia (CML) treated with imatinib, a short duration of response with eventual emergence of imatinib resistance has also been reported in a subset of CML patients. The most frequent clinically relevant mechanisms that change imatinib sensitivity in BCR-ABL-transformed cells are mutations within the Abl kinase domain, affecting several of its properties. Crystal structure analysis of the Abl-imatinib complex has proven helpful in identifying potential critical residues that hinder interactions of imatinib with mutated Abl. This has led to the development of a second generation of targeted therapies such as nilotinib and dasatinib, already in phase II clinical trials or SKI-606 and MK-0457 in phase I trials. In this review, we discuss the activity of nilotinib, developed by Novartis using a rational drug design strategy in which imatinib served as the lead compound. Preliminary studies demonstrated that nilotinib has more efficacy than imatinib in inhibiting proliferation of BCR-ABL-dependent cells, a relatively safety profile and clinical efficacy in all phases of CML

Combined Double-breasted Full-thickness Abdominal Flap Plication and Acellular Dermal Matrix in Prune-belly Syndrome Reconstruction

Background: Reconstruction of the abdominal wall in patients with prune-belly syndrome (PBS) following previous intra-abdominal procedures is a challenging problem with a high incidence of revision due to persistent bulging or herniation. The abdominal wall flaccidity not only produces a severe psychological and aesthetic discomfort for the patient but often determines functional disabilities, including inability to cough properly, impaired bowel and bladder function, and delay in posture and balance. Methods: The authors describe three cases of reconstruction of abdominal wall using a modified double-breasted abdominoplasty fascial plication with additional acellular dermal matrix interposition and review the literature for innovations in the use of abdominal repair for reconstruction of these difficult cases. Results: Three children with PBS at a mean age of 7.3 years achieved successful reconstruction of the abdominal wall, using the modified double-breasted abdominoplasty fascial plication with acellular dermal matrix interposition. Patients underwent previous procedures, including orchiopexy in two patients and bilateral nephrectomy in one patient. No postoperative complications have been found, apart from superficial skin dehiscence along the abdominal incision treated conservatively in one child. At mean follow-up of 42 months (range 28–56 months), no patient presented incisional hernia, persistent or recurrent fascial laxity with abdominal bulging. All patients achieved significant aesthetic and functional improvements, including children’s ability to cough, spontaneous gain of abdominal tonus, balance, and ambulation. Conclusion: Modification of the original vertical, two-layer plications of the deficient abdominal interposing biological mesh has the purpose of improving strength, aesthetics, and function of the abdominal wall in pediatric patients with PBS

Necrobiosis Lipoidica Affecting the Leg: What Is the Best Treatment in a Patient with Very High Aesthetic Demand?

Summary: Necrobiosis Lipoidica (NL) is a rare necrotising disorder of the skin characterized by collagen degeneration, thickening of blood vessels, and granulomatous inflammatory process. Its main clinical features are brownish-red papules and yellowish plaques with atrophic central areas. NL affects 0.3% -1.2% of the diabetic population, mostly women (female/male ratio is 3:1). Management of NL is challenging, especially for large lesions refractory to medical therapy, thus requiring surgical excision as an alternative option. Due to the rare occurrence of this condition no treatment guidelines exist and individualized treatment mostly depends on the severity of the lesion, location and patient's expectations. A case of a 30-year-old diabetic woman with very high aesthetic expectations was succesfully treated with staged resections of a giant NL to the leg and reconstruction with dermal template and full thickness skin grafts. Grafts were taken from the groin region bilaterally and from the lower abdomen after a cosmetic mini-abdominoplasty procedure. This approach allowed for a stable and very satisfactory aesthetic result with no donor site exposed scars

Obturator nerve split for gracilis free-flap double reinnervation in facial paralysis

The use of a double-powered free muscle transfer for facial reanimation has been reported by several authors with different types of nerve coaptation. A new nerve coaptation strategy is presented herein. We performed a 1-stage double-powered free gracilis muscle flap transfer in a patient with long-standing facial paralysis by splitting the obturator nerve and anastomosing the 2 free ends to the contralateral facial nerve (through a sural graft) and to the masseteric nerve. Voluntary movement of the transferred muscle with teeth clenching was observed at 6 months after the operation and a symmetric smile with bilateral elevation of the mouth angle at 10 months. Our limited experience suggests that in case of a large cross-section of the obturator nerve, the latter can be split and sutured to the ipsilateral masseteric nerve and to the contralateral facial nerve with a sural graft by double end-to-end anastomosis
