RESUMEN
Similar to other developing countries, the elderly population has increased in Türkiye in the last 30 years. Due to this increase, there has been a rise in the number of elderly patients suffering from maxillofacial injuries. This retrospective study aimed to evaluate the data of patients with geriatric facial trauma treated in our trauma center between 2010 and 2022 and the leading types of injuries, their causes, accompanying findings, and preferred treatment methods according to sex and age. In the study, the demographic characteristics, including age, sex, comorbidities, causes and sites of injury, treatment options, accompanying injuries, and facial injury severity scores of 292 patients were analyzed. Among more than 4000 patients undergoing treatment for maxillofacial injuries screened from January 2010 to August 2022, 292 (166 males, 56%; age range, 65-98 years) fulfilled the eligibility criteria for the study, of whom 60 had a surgical operation. Falls were the most typical cause of injury (70.20%), followed by motor vehicle accidents (18.15%) and assaults (7.87%). Zygomaticomaxillary complex fractures were the most frequently encountered fracture type (n=126, 29.92%), followed by nose fractures (n=122), orbital fractures (n=85), and mandible fractures (n=72). It was observed that the fractures were managed by surgical intervention or conservative measures and that conservative treatment was mostly preferred at an increasing rate with advancing age. As the elderly population increases, so does the incidence of geriatric facial trauma. Due to increased age, deterioration of health, and increase in the number of comorbidities, surgical interventions are less preferred.

OBJECTIVE: One of the most important factors that adversely affects the outcome of peripheral nerve surgery is the formation of epineural and extraneural scar tissue after surgery. Many surgical methods and pharmacological and chemical agents have been used to prevent the formation of epineural scar tissue, but satisfactory results have not been achieved in clinical applications. The purpose of this study was to investigate the combined effect of fat graft and platelet-rich fibrin on the formation of epineural scar tissue and on nerve healing in the mature rat model. METHODS: A total of 24 female Sprague-Dawley rats were used. A circumferential segment of epineurium was excised from both bilateral sciatic nerves. The epineurectomized right nerve segment was wrapped with a combination of fat graft and platelet-rich fibrin (experimental group), while the left nerve segment did not receive any surgical procedure other than the epineurectomy (sham group). Notably, 12 randomly selected rats were sacrificed in the fourth week for histopathological examination of early results. The other 12 rats were sacrificed in the eighth week for late results. RESULTS: The formation of fibrosis, inflammation, and myelin degeneration were less common in the experimental group, while nerve regeneration was found to be higher at both 4 and 8 weeks. CONCLUSION: The intraoperative application of a combination of fat graft and platelet-rich fibrin appears to be effective on nerve healing after surgery at both the early and late periods.

RESUMEN
BACKGROUND: The postoperative development of epineural and extraneural scar tissue adversely affects peripheral nerve surgery outcomes. Although several surgical methods, pharmacological agents, and chemical materials have been used to prevent epineural scar formation in both clinical and experimental models, the results are still unsatisfactory. The purpose of this study was to investigate the efficacy of buccal mucosa graft (BMG) wrapping on epineural scarring in an adult rat model. METHODS: Bilateral sciatic nerves were carefully exposed in 24 adult Sprague-Dawley rats, and a circumferential segment of epineurium (0.5 cm) was excised from both nerves. The epineurectomised left nerve segment was wrapped with a BMG (experimental side), while the right nerve segment did not receive any surgical procedure other than the epineurectomy, and served as the control side. To perform gross and histopathological examinations, 12 randomly selected rats were euthanised at 4 weeks postoperatively, and the remaining rats were euthanised at 8 weeks. RESULTS: The left sciatic nerve that was wrapped with a BMG following epineurectomy showed significantly less nerve adhesion at 8 weeks (p = .018), and less epineural scar tissue at both 4 (p = .014) and 8 weeks (p = .025). Inflammation of the BMG-wrapped nerves was increased at 4 weeks (p = .029), but not at 8 weeks. CONCLUSION: BMG wrapping decreases postoperative adhesion and scar tissue formation of epineurectomised healthy nerves, despite the presence of increased inflammation in the early postoperative period.

BACKGROUND: The aim of this study was to demonstrate a new, easy and safe technique, which has not been defined in the literature previously, that enables the gradual primary closure of fasciotomy wounds using barbed sutures. METHODS: The technique was performed on five patients who presented with fasciotomy wounds on both upper and lower extremities, varying in size, observed after compartment syndrome due to different causes. The average width of the defects for which primary closure was planned was 8.8 cm. Following the fasciotomy incision, absorbable barbed sutures were inserted through the dermal tissue around the wound similar to that of a subcuticular closure, but left loose, after which closed dressing was applied. During the clinical follow-up, with the decrease in tissue edema and tightness around the wound, the barbed suture was tightened at bedside every 48-72 hours. RESULTS: At the end of this gradual closure, all the fasciotomy defects were primarily closed within an average of 8.6 days. All the patients had complete and uncomplicated primary closure with the exception of one with high-voltage electrical burn injury, who developed necrosis in the distal part of the defect, and was treated by secondary healing. CONCLUSION: The gradual fasciotomy closure technique with barbed suture seems to be an easy, rapid and effective method.

Temporomandibular joint dislocation is defined as the movement of condyle out of the fossa and the advancement of the posterior surface of the condyle in front of the articular eminence. If this condition becomes chronic, surgical treatment is the only option. The goal of surgical treatment is to reposition the condyle and prevent further recurrences. In this study, a retrospective analysis is presented examining 73 patients and 83 joints that were treated with hook-shaped miniplates and miniscrews fixed to otolog bone grafts. Records were obtained from archives of the Uludag University Medical Faculty, Plastic, Reconstructive and Aesthetic Surgery Department. The duration of postoperative follow-up was 3-30 months. In one case, the miniplate was fractured, and in two cases, abscesses existed. This study aims to emphasize that using miniplates and otolog bone grafts is more cost effective.
RESUMEN
BACKGROUND: The aim of this study was to investigate the efficacy of three injections of hyaluronic acid (HA) versus placebo (saline) over a two-week period on functional outcomes after zone-II flexor tendon repairs. METHODS: Twenty-two patients with isolated zone-II flexor tendon injury of the index fingers were included in this study. Before tenorrhaphy, fingers were randomly divided into two groups; 11 were treated with three injections of HA around the tenorrhaphy site and 11 served as a placebo group and were treated with saline in the same way. The first dose was given at the time of tenorrhaphy and two additional doses were given at one-week intervals. A Kleinert rehabilitation protocol was employed postoperatively. Range of motion was assessed with total active and passive movement evaluation systems at 3 weeks, 3 months and long-term. Functional outcome was evaluated using the Strickland classification. RESULTS: There were no differences between the two groups in terms of range of motion at 3 weeks. However, at 3 months and long-term, a significant improvement was observed in fingers treated with HA compared to placebo. CONCLUSION: This preliminary placebo-controlled study suggests that repetitive injections of HA can improve clinical outcomes presumably due to the effect on decreasing adhesions in primary tendon repairs.

BACKGROUND: The purpose of this study was to review tractor-related childhood hand injuries. METHODS: Seventy children (53 males, 17 females; range 1 to 11 years) were admitted to our unit. Patients were analyzed according to sex, age, pattern of injury, type of treatment and functional results. The first step of the treatment included extensive debridement and irrigation. Patients with complex tissue defects were treated with multi-stage reconstruction procedures. Patients with amputations or partial amputations were treated with amputation of the devascularized digits. RESULTS: The most common injuries were amputations and complex tissue defects. Other types of injuries were fractures, partial amputations and skin defects. In 20 cases, skin defects were covered with split-thickness skin grafts and the functional results were good. In 40 cases with complex soft tissue injuries, skin defects were covered with flaps. The functional results were good in 30 and fair in 10. In 50 digits with complete amputations, attempts at revascularization immediately after injury failed in all patients. The functional results were good in 40, fair in 5 and poor in 5. All fractures healed in 6 weeks and no complications related with bone healing were observed. CONCLUSION: The concepts of aggressive debridement, fracture reduction, and early soft tissue coverage are central to the care of these hand injuries.

Since the electrosurgical instruments are commonly used in a wide variety of surgical specialties, understanding of the properties of these instruments is very important to prevent the potential complications. We report the case of a patient who sustained a third-degree dermal burn caused by contact with the ground plate of the electrosurgical system. This burn healed with surgical treatment. Since electrosurgery causes serious complications, surgeon and operating suite personnel should pay attention to the electrosurgical system during the operation. Additionally, patients must be informed about these complications.

After the chondrogenic potential of free grafts of perichondrium was shown in several experimental studies, perichondrium has been used to reconstruct cartilage tissue in various clinical situations. This study investigates the effects of human amniotic fluid on neochondrogenesis from free perichondrial grafts in a rabbit model. Since this fluid contains high concentrations of hyaluronic acid, hyaluronic acid-stimulating activator, growth factors, and extracellular matrix precursors during the second trimester, it may have a stimulating effect on neochondrogenesis. Perichondrial grafts, measuring 20 x 20 mm2 were obtained from the ears of 144 New Zealand young rabbits and were sutured over the paravertebral muscles. The rabbits were randomly divided into three groups with 48 rabbits per group. In group 1, 0.3 ml human amniotic fluid, and in group 2, 0.3 ml saline were injected underneath the perichondrial grafts. Group 3 formed the control group in which no treatment was given. Histologically, neochondrogenesis was evaluated in terms of cellular form and graft thickness at 2, 4, 6, and 8 weeks after surgery. In group 1, the mature cartilage was generated quickly and the cartilage plate in this group was significantly thick and extensive when compared with groups 2 and 3 at 8 weeks ( p<0.05 ANOVA). In conclusion, our study shows that human amniotic fluid enhances neochondrogenesis from free perichondrial grafts. The rich content of hyaluronic acid and growth factors possibly participate in this result.

BACKGROUND: We retrospectively evaluated patients who underwent treatment for necrotizing fasciitis within a five-year period. METHODS: Thirty patients (4 females, 26 males; mean age 55 years; range 19 to 78 years) with necrotizing fasciitis were evaluated with respect to age, sex, etiology, predisposing factors, localization of infections, culture results, and treatment methods and results. RESULTS: The most common etiologic and predisposing factors were anorectal lesions (36.7%) and diabetes (53.3%), respectively. Wound cultures yielded Pseudomonas aeruginosa in 50% of the patients. Two strains of aerobic bacteria were isolated in three patients. All patients underwent extensive surgical debridement and received antibiotic therapy. Twenty-nine patients (96.6%) required more than one debridement, with a mean of 4.5 debridements. The ensuing skin defects following debridement were reconstructed with grafts or local flaps. No complications were encountered in the postoperative period. CONCLUSION: Early diagnosis and treatment result in decreased morbidity and prevent mortality in necrotizing fasciitis.

This study was designed to evaluate the epidemiology and outcome of burn injuries due to paint thinner in a local burn center. During a 10-year period, 32 patients were admitted to our Burn Unit for paint thinner thermal burn. Patients were reviewed regarding the age, sex, etiologic factors, extent and localization of burn, treatment methods, length of hospitalization, and results. There were 30 males and 2 females. The mean age of patients was 25.9 +/- 11 years. The most common etiologic factor was kindling a fire with paint thinner. The mean extent of burn was 33.6 +/- 24% of the total body surface area. All patients sustained burn injury on the face, arms, and hands and five patients among them had extended burn areas on the trunk and/or lower extremity. The mean length of hospitalization for the survivors was 34.5 +/- 21.6 days. Twenty-eight patients were treated by early excision and split-thickness skin grafting. In four patients, burn wounds were healed by conservative management. Five patients with burn size of over 75% of the total body surface area died. In conclusion, paint thinner may be the cause of a catastrophic thermal injury and should not be used for the purpose of kindling fire.

The purpose of this study was to investigate the effects of combined application of human amniotic membrane wrapping and hyaluronic acid injection on peripheral nerve scarring in an adult rat model. After circumferential epineurectomies of right sciatic nerves were performed in each of 72 rats, nerves were randomly divided into three groups: (1) nothing was done additional to epineurectomy; (2) the epineurectomized segment was wrapped with human amniotic membrane; and (3) the epineurectomized segment was wrapped with human amniotic membrane and hyaluronic acid was injected inside. The extent of adhesions and perineurial scar thickness was macroscopically and histologically evaluated at 4 and 12 weeks. The least adhesion and perineurial scar tissue were observed in nerves treated with human amniotic membrane wrapping and hyaluronic acid injection. This combination appears to be safe and effective in preventing perineurial scar formation after peripheral nerve surgery in rats.

BACKGROUND: We retrospectively reviewed patients who were treated and followed-up for mandibular fractures within a 10-year period. METHODS: A total of 204 patients (158 males, 46 females; mean age 22.4 years; range 5 to 72 years) were retrospectively evaluated with respect to age groups, sex, etiology, associated injuries, localization and type of the fractures, treatment methods, and early and late complications. The follow-up period ranged from four months to 10 years. RESULTS: The most common cause of injury was traffic accidents (44.1%), followed by falling (31.8%), and violence (17.1%). The highest incidence occurred at ages 21 to 30 years. Of 283 fractures detected, the most common fracture sites were the parasymphysis (83 fractures, 29.3%) and the angulus (52 fractures, 18.4%). Forty-eight patients (24%) had associated injuries. The type of the fractures was simple in 80 patients (39.2%), and complex in 62 patients (30.4%). Treatment included open reduction with titanium mini-plates and screws in 130 patients, and intermaxillary fixation in the remaining patients. The fractures recovered without any complications in 167 patients (81.8%). No occlusion-related complications occurred in the late follow-ups. Complications were encountered in 37 patients (18.1%), being in the early (malocclusion in 5.9%, infections in 2.5%, inferior alveolar nerve injuries in 2.5%) or late (plate-screw exposition in 4.4%, ankylosis of the temporomandibular joint in 2%, and orocutaneous fistula in 1%) postoperative periods. CONCLUSION: Rigid fixation should be the first choice of treatment in mandibular fractures.

OBJECT: Peripheral nerve repair surgery is still replete with challenges. Despite technical improvements in microsurgery, classic methods of nerve repair have failed to provide satisfactory results. The purpose of this study was to investigate the effects of amniotic fluid from humans on peripheral nerve scarring and regeneration in rats. METHODS: Forty adult Sprague-Dawley rats were used in this study. After the right sciatic nerve in each rat was transected and repaired using an epineural suture procedure, the nerves were divided into two groups according to the solution applied around the repair site: experimental group, 0.3 ml human amniotic fluid (HAF); and control group, 0.3 ml saline. Macroscopic and histological evaluations of peripheral nerve scarring were performed 4 weeks postsurgery. Nerves treated with HAF demonstrated a significant reduction in the amount of scar tissue surrounding the repair site (p < 0.05). No evidence of a reaction against HAF was noted. Functional nerve regeneration was measured once every 2 weeks by using a sciatic function index until 12 weeks postsurgery. Functional recovery in nerves treated with amniotic fluid occurred significantly faster than that in nerves treated with saline (p < 0.05). Peripheral nerve regeneration was evaluated histomorphologically at 12 weeks postsurgery. Nerves treated with amniotic fluid showed significant improvement with respect to the indices of fiber maturation (p < 0.05). CONCLUSIONS: Preliminary data show that HAF enhances peripheral nerve regeneration. The preventive effect of HAF on epineural scarring and the rich content of neurotrophic and neurite-promoting factors possibly contribute to this result.

The purpose of this experimental study was to investigate the effects of topical applications of hyaluronic acid on peripheral nerve scarring and regeneration in an adult rat model. After the right sciatic nerves of 48 rats were transected and immediately repaired, nerves were randomly divided into two groups. Nerves to which were applied hyaluronic acid comprised the experimental group, and nerves to which were applied saline comprised the control group. Perineural scarring was evaluated at 4 and 12 weeks macroscopically and histologically. Nerves treated with hyaluronic acid demonstrated significant reduction in perineural scar thickness (P < 0.05, Student's t-test). Histomorphologic nerve analysis, electrophysiologic studies, muscle mass evaluation, and serial functional walking-track analysis were performed for evaluation of peripheral nerve regeneration at 12 weeks. The results showed better conduction velocities, increased axon-fiber diameter, and faster functional recovery in hyaluronic acid-treated nerves (P < 0.05, Student's t-test). In conclusion, hyaluronic acid appears to be effective in preventing perineural scar formation, resulting in enhancement of peripheral nerve regeneration.
