Nail bed reconstruction is crucial after fingertip trauma, impacting both function and aesthetics. In this article, the authors describe a case of partial distal phalanx amputation of the index finger with laceration of the nail bed's remaining part. A traumatically elevated skin-fat flap covered the exposed bone on the fingertip, preserving finger length and sensitivity on the radial side. A full-thickness skin graft from the forearm closed a secondary defect on the finger pulp. Nail bed suturing prevented scarring and nail deformity, and a temporary artificial plastic nail replacement maintained the nail bed's shape. Temporary artificial nail replacements protect the regenerating fingertip bed, promote healing, and prevent nail deformities. Proper adaptation of lacerated nail bed edges, supported by either the patient's own nail or a temporary artificial nail, is crucial for optimal fingertip restoration, including proper nail shape.

Introduction: Pedicled flaps are prioritized in the free flap era for reconstruction only in institutions without sufficient microsurgical support. They are reliable for reconstruction, but with a lot of advantage, including cost, operating and hospitalization time, easy learning curve and better management of older and polymorbid patients, not suitable for the free flap reconstruction. The experience from two institutions with various types of pedicled flaps are presented in this retrospective study.

Material and methods: A total of 62 patients were enrolled in this study. With 63 flaps harvested, 1 patient underwent two reconstructions. Operations were performed in two centers. Evaluation of parameters, like age and gender of patients, indication for reconstruction, type and extent of the primary surgery, type of the pedicled flap, the primary or salvage reconstruction, complications of reconstruction and survival of flaps, was included.

Results: The median age of this cohort was 64 years (range 30-82 years) with male predominance (53 male to 9 female patients). Five groups of flaps were designed: myocutaneous, myofascial, myomucosal, fasciocutaneous and muscular flaps. Thirteen types of pedicled flaps were utilized. The most frequent flap was the infrahyoid myocutaneous flap (IHMF) in 26 patients, followed by the pectoralis major myocutaneous flap (PMMC) in 14 patients, including 15 flaps. In 1 patient, the second reconstruction was required with harvesting PMMC from the other side. Indications for reconstruction were defects after either primary or salvage surgery in 30 and 32 patients respectively. Reconstructions of the mobile tongue (13 patients) and floor of the mouth (13 patients) with IHMF predominated after primary resection in this area, followed by PMMC (three patients). In a group of defects after salvage surgery, the most frequent reconstructed area was the neck, where PMMC was preferred in 5 patients. PMMC was otherwise the most frequent type of flap utilized in salvage reconstruction (14 flaps in 13 patients). The overall cumulative flap survival was 96.8% with total flap loss in 2 patients.

Conclusion: Various flaps are favored according to institutions, however, the alternative flaps should be considered, if necessary. Pedicled flaps are still valuable options in the most of minor reconstructive centers even in well developed countries and should be reserved for reconstruction in major centers, primarily utilizing free flaps, for indicated patients, not suitable for a microsurgical reconstruction.

Successful engraftment of skin grafts highly depends on the quality of the wound bed. Good quality of blood vessels near the surface is critical to support the viability of the graft. Ischemic, irradiated scar tissue, bone and tendons will not have the sufficient blood supply. In such situations flaps are to be resorted. However, the flaps also need to have good vascularity over the limbs. The introduction of dermal substitutes has provided a novel method for repairing various severe skin defects. These substitutes act as dermal regenerative templates, which facilitate dermal reconstruction and regeneration. This study was done to ascertain the effectiveness of these substitutes in the treatment of complex wounds. Between January 2022 and June 2023, 20 patients who had complex wounds, which could not be treated with simple skin grafting and who were treated with collagen and elastin matrix and split skin grafting (SSG) were retrospectively studied. The percentage of SSG take as per the records was noted at a 10-day post-operative period. Patient characteristics, comorbidities, duration and outcomes of the treatment were noted. Twenty patients were included in the study. The minimum size of the ulcer was 5 × 4 cm (area of 20 cm2) and the maximum size of the ulcer was 15 × 15 cm (225 cm2). Average take of skin graft was 93.7% at 10th post-operative day. Recurrence at 6 months was nil. The scar quality was assessed by patient and observer at 3 months and 6 months post-operatively. The lower-limb ulcers with compromised surrounding tissue are complex. The major goal in these cases is to do simple surgery and prevent recurrence. The collagen and elastin matrices provide structural support for cellular infiltration, which helps maximize a SSG take and a stable long-term scar.

Nowadays, median nerve entrapment is a frequent issue. Many physicians are familiar with the most common median entrapment, which is the carpal tunnel syndrome (CTS). By contrast, less frequent entrapments, historically called "pronator syndrome" are still misdiagnosed as overuse syndrome, flexor tendinitis or other conditions. This article is meant to introduce proximal median nerve entrapments, followed by a case report of the rarest example - anterior interosseous nerve syndrome (AIN syndrome).

Nowadays, techniques and the use of patient specific implants seem to be the recent high technology standard in reconstructive surgery. Surgery planning is as old as the surgery procedures themselves. Any good surgeon, before entering the operating theatre, has a plan for how to proceed. It is based on knowledge and experience in combination of evaluation of all case relevant information. In fact, virtual surgery planning and CAD/CAM reflects the technological "state of the art" into the medical daily practice. Recently, 3D printing technologies became easy and accessible for everyone. Virtual 3D images substituted the plaster models, the film profile analysis switched to digital, 3D printed bone models of the case helped to understand the morphology of the deformity and prepare the osteotomies with "hands on the bone". The authors' own 20 years of experience on surgical planning, the development of digital technologies in oral and maxillofacial surgery is traced and comments on case examples are presented.

Background: Scalp arteriovenous malformations (SAVM) are extremely uncommon vascular malformations, with only ~200 cases published in the English language in the past years. The objective of the present study was to describe the experience of a single reference service in neurosurgery.

Methods: This is a descriptive and retrospective study conducted at our institution, which included cases of SAVM treated between 2001 and 2022. All information were extracted from the medical records of our institution. Patient confidentiality was preserved. Furthermore, an illustrative case has been described in detail.

Results: Seven patients were included. The male-to-female ratio was 2.5: 1 and the mean age was 23.3 (3-42) years. Most cases (56.4%) were spontaneous and the lesions were located in the frontal (28.7%) and parietal (28.7%) regions. All lesions were supplied by more than one feeder, with the superficial temporal and occipital arteries being the most commonly involved (71.5%). Six patients underwent preoperative embolization, and 56.4% patients had scalp necrosis. Five patients underwent surgical resection, all without recurrence and with good postoperative evolution.

Conclusions: More than one artery was involved in all cases, and the properties of the involved vessel influences the approach strategy. Surgical treatment is curative, and preoperative embolization helps reduce bleeding during the surgery. Complete resection of the lesions prevents associated complications, such as bleeding or recurrence. Scalp necrosis is a frequent complication in the treatment of these lesions, and a multidisciplinary approach involving reconstructive plastic surgery should always be considered.

Ischemic limb necrosis due to high dose of norepinephrine (NE) in a patient with septic shock is uncommon. Unfortunately, amputation of necrotic parts is the only available treatment. Reconstruction with skin autografts for defects resulting from the amputation of the lower limbs is challenging. Herein we report a case of digit necrosis in the upper and lower limbs after administration of a high dose of NE > 1 μcg/kg/min in a patient with septic shock. The source of infection that led to septic shock was not detected. Surgical amputation was performed as it was impossible to repair impaired vasculature and patients' life was endangered. Large defects were covered with skin autografts from the patient's thighs. The included figures demonstrate the extremities' appearance before, after amputation, during and after skin graft transplantation.

Lymph node transfer has recently become one of the popular techniques for surgical treatment of lymphedema. We aimed to evaluate postoperative donor site numbness and other complications in patients who underwent supraclavicular lymph node flap transfer to treat lymphedema with preservation of the supraclavicular nerve. From 2004 to 2020, 44 cases of supraclavicular lymph node flap were reviewed retrospectively. In the donor area, sensorial evaluation was clinically done with the postoperative controls. Among them 26 had no numbness at all, 13 had short-term numbness, two had numbness for > 1 year and three had numbness for > 2 years. We suggest that careful preservation of the supraclavicular nerve branches can avoid the major complication of numbness around the clavicle.

Introduction: It is often questioned whether to perform replantation or revision amputation for amputation injuries in elderly patients and smokers. According to the current indication criteria, neither old age nor smoking in the absence of other risk factors are considered to be risk factors for replantation failure. However, many microsurgeons still may make the decision not to perform digital replantation based solely on these factors.

Material and methods: In order to evaluate the influence of both factors, we provided univariate and multivariate analyses of patients who underwent replantation at our centre during a 10-year period. We divided patients in two groups according to age (< and ≥ 60 years) and smoking status.

Results: In the univariate analysis, there were no differences in immediate results between the two age groups. In the multivariate analysis, no statistical difference was found in neither long-term nor short-term results between the two age groups and between smokers and non-smokers.

Conclusion: Smoking and age should not be considered the only risk factors when deciding whether to perform digital replantation.

Background: Eagle's syndrome (ES) is a term describing a group of symptoms associated with the elongation of the styloid process (SP) of the temporal bone or with ossification of the stylohyoid ligament. Clinically, it manifests through pain in the orofacial and pharyngeal regions, similar to that experienced by patients with temporomandibular joint disease. The presented paper aims to assess the evaluation of the success of surgical treatment and the complications associated with such treatment.

Methods: Our retrospective study includes nine patients with ES treated in our Department Oral and Maxillofacial Surgery in years 2019-2023 (median age of 47 years) - all patients affected with this disease out of 2,716 patients examined at our department due to a temporomandibular joint disease. Eight of these patients underwent a surgical resection of the SP. The success and complications in these patients are evaluated in this study.

Results: In seven patients, the problems disappeared or at least diminished, which is consistent with data from the literature. Postoperative complications such as deficit of the marginal branch of the facial nerve (n. VII), limited sticking the tongue out (n. XII), and velopharyngeal insufficiency (n. IX) occurred in three patients.

Conclusion: The wide spectrum of clinical manifestations makes ES a condition that should be considered in the differential diagnosis of temporomandibular joint disorders, post-traumatic conditions, or complicated eruption of wisdom teeth or their extraction. ES can be treated conservatively or (mostly) surgically. Surgical treatment can be relatively successful and effective, but it is necessary to respect the anatomical placement of the SP, which can be associated with the development of complications, especially in cases with extremely long SP.
