Evaluating the efficacy of recombinant human growth factors in scar remodelling for patients with facial soft tissue injuries.

Facial soft tissue injuries, often resulting in scarring, pose a challenge in reconstructive and aesthetic surgery due to the need for functional and aesthetic restoration. This study evaluates the efficacy of recombinant human growth factors (rhGFs) in scar remodelling for such injuries. A retrospective evaluation was conducted from January 2020 to January 2023, involving 100 patients with facial soft tissue injuries. Participants were divided equally into a control group, receiving standard cosmetic surgical repair, and an observation group, treated with rhGFs supplemented cosmetic surgery. The study assessed scar characteristics (pigmentation, pliability, vascularity, height), hospital stay duration, tissue healing time, complication rates and patient satisfaction. The observation group demonstrated significant improvements in all scar characteristics, with notably better pigmentation, pliability, vascularity and height compared with the control group. The rhGF treatment also resulted in reduced hospital stay duration and faster tissue healing. Notably, the total complication rate was significantly lower in the observation group (10%) compared with the control group (34%). Additionally, patient satisfaction levels were higher in the observation group, with 98% combined satisfaction compared with 76% in the control group. The application of rhGFs in treating facial soft tissue injuries significantly enhances scar remodelling, expedites healing, reduces complications and improves patient satisfaction. These findings establish rhGFs as a valuable tool in the management of facial soft tissue injuries, highlighting their potential in improving both functional and aesthetic outcomes.

Invasive Cutaneous Facial Mucormycosis in a Trauma Patient.

Mucormycosis, also known as zygomycosis, is an aggressive infection caused by a ubiquitous group of molds known as mucormycetes and is often associated with immune suppression or trauma among immunocompetent populations. We present the case of a 19-year-old woman who was involved in a motor vehicle accident in whom rapidly progressive invasive cutaneous facial mucormycosis subsequently developed. The diagnosis, treatment options, and incidence of this disease process are discussed in the context of trauma.

O2C Laser Doppler and Digital Photo Analysis for Treatment Evaluation of Beta-Glucan versus Provitamin Pantothenic Acid of Facial Burns.

Various creams are available for superficial second-degree burns (SSDB) of the face. We evaluated provitamin pantothenic acid versus ß-glucan for SSDB of the face using the O2C laser Doppler system and digital photo analysis. Out of 20 patients (January to December 2012) with facial burns, 7 with SSDB of both cheeks were included to our study. Burned cheek wounds were treated using pantothenic acid or ß-glucan. Digital photos of marked regions were taken daily from predefined distances. Microcirculation was measured at marked regions for 7 days at scheduled time points using the O2C laser Doppler. Data were evaluated using the SPSS program (SPSS Inc., Chicago, IL). Wounds treated with ß-glucan showed faster reepithelialization. O2C laser Doppler measurements showed faster increase in SO2, microvascular perfusion, hemoglobin content, and blood flow. This correlated good with clinical Vancouver Scar Scale results. Although not statistically significant, ß-glucan cream therapy of SSDB results in aesthetically superior outcome and faster reepithelialization.

Contemporary update on the treatment of dog bite: injuries to the oral and maxillofacial region.

PURPOSE: The purpose of the present retrospective record review was to evaluate the patient demographics, treatment rendered, and long-term outcomes of patients injured in dog bite attacks to the oral and maxillofacial region. MATERIALS AND METHODS: In the present study, a retrospective medical record review was conducted of patients treated by the oral and maxillofacial surgery department at the University of Tennessee Medical Center who had presented with injuries to the head, neck, and face region from dog bite attacks from February 1, 2006 to October 31, 2013. Each patient included had to have had at least 1 follow-up visit. The data obtained from the patients' medical records included patient demographics, event details, injuries sustained, and treatment rendered and analyzed. RESULTS: The medical records from 20 patients were included and reviewed. More than one half (60%) of the patients were younger than 12 years old. The dog was owned by the patient or a relative in 58% of the cases. The children sustained injuries requiring hospital admission and repair in an operating room setting more often than did the adults. Pit bulls were more frequently associated with injuries than other breeds (9 of 20). CONCLUSIONS: Our patients required a total of 28 hospital inpatient days, 29 total procedures, and follow-up treatment for up to 2 years. Our review has shown the complexity of soft tissue injury treatment and the significant financial impact associated with dog bite injuries owing to the multiple hospital admissions, surgical revisions, and lengthy follow-up period required.

The effect of memantine on functional recovery of the facial nerve after crush injury.

The objective of this study is to establish whether memantine is an alternative and effective treatment on facial nerve recovery after crush injury, and also to analyze the effective doses of this promising agent. This is a randomized controlled animal study. 40 rats underwent crush injury to left main trunk of the facial nerve, and divided into 4 groups; (1) control (saline treated), (2) 5-mg/kg memantine, (3) 10-mg/kg memantine, and (4) 20-mg/kg memantine group. Facial nerve functions were evaluated by eye reflex, and whisker movement compared to the unaffected side. They were scored on a 3-point scale. On day 28, the rats were sacrificed, and the facial nerves were dissected. The paraffin sections were studied with caspase-3 immunostaining. According to statistical data, the recovery in Group 4 began significantly earlier than the other groups on the basis of restoring eye blink reflexes and whisker movement. Groups 2 and 3 showed faster recovery than Group 1 on the basis of whisker movement. The caspase-3 positive staining was rarely detected in all groups. The Kruskal­Wallis test revealed that Group 4 showed fewer apoptotic cells than other groups; this was statistically significant. However, the Mann­Whitney U test with the Bonferroni correction did not reveal any significant difference between the groups. In conclusion, this study revealed that memantine acted to restore facial nerve functions, and accelerate recovery after facial nerve injury by inhibiting apoptosis.

Facial skin breakdown in patients with non-invasive ventilation devices: report of two cases and indications for treatment and prevention.

Non-invasive ventilation (NIV) provides an effective ventilatory support in patients with respiratory failure without endotracheal intubation. However, there are potential problems with its clinical application and the development of pressure ulcers represents a common complication. Often several intensive care units treat facial skin breakdown related to NIV. In this article, we report our experience in treatment and prevention of these lesions, emphasising the higher risk of certain age groups to develop them, such as preterm infants and elderly patients with comorbidities. We performed daily disinfection of the lesions followed by application of topical cream containing hyaluronic acid (HA) sodium salt. In addition, in order to prevent worsening of injury, we applied a cushion made of gauze pad containing HA sodium salt between the skin and the masks, so as to reduce friction between the NIV devices and the skin. Local medical treatment allowed complete reepithelialisation of the injured skin areas. Systematic monitoring of patients' faces is essential to detect early damages and to intervene with appropriate therapy, especially in preterm infants and elderly. Moreover, refining the devices with the proposed protective cushion can reduce pressure ulcers and increase comfort for the patients.

Coadjuvant treatment with surgery and pirfenidone in severe facial trauma due to dog bite.

BACKGROUND: This case report assesses the effectiveness of surgery plus pirfenidone (PFD) as a concomitant therapy in the management of facial trauma after severe dog bite. METHODS: A 16-month-old female patient who suffered a severe attack by a big-sized dog (Rottweiler) in the midface area was managed with surgery/PFD combination and followed up for 20 months to evaluate the efficacy to control, prevent, and improve injury sequels. RESULTS: Surgery/PFD combination offered a good complementary therapy downregulating inflammatory activity, improving blood supply, and activating cytokine modulation and collagen synthesis/biosynthesis (scar control). No side effects were reported in this case report. CONCLUSIONS: Surgery/PFD management for severe facial dog bites represents a safe and effective therapeutic option to protect and improve a patient's quality of life, minimizing long-time sequels.

Primary repair of facial dog bite injuries in children.

OBJECTIVES: The management of dog bite wounds is controversial, and current data on risk of infection are variable and inconsistent. Furthermore, the use of prophylactic or empiric antibiotics for the treatment of these wounds is debatable. We investigate the rate of wound infections and other complications after primary repair of pediatric facial dog bite injuries. METHODS: We reviewed 87 consecutive patients aged 18 years or younger who had facial dog bite injuries from January 2003 to December 2008. Variables examined were age, sex, setting of repair, number of sutures used for repair, whether surgical drains were used, and antibiotic administration. End points measured were incidence of wound infection, need for scar revision, and any wound complications. RESULTS: The mean age of patients was 6.8 years, and the majority were women (53%). All facial injuries were primarily repaired at the time of presentation either in the emergency department (ED; 46%), operating room (OR; 51%), or an outpatient setting (3%). All patients received an antibiotic course, none of the patients developed wound infection, and no subsequent scar revisions were performed. Three patients repaired in the OR underwent placement of a total of 4 closed-suction drains. The mean (SD) age of patients repaired in the OR was significantly younger than those repaired in the ED (5.7 [3.9] vs 8.0 [4.5] years, respectively; P < 0.01). The number of sutures used were greater for patients repaired in the OR than in the ED (66.4 [39.6] vs 21.7 [12.5], respectively; P < 0.01). CONCLUSIONS: Intuitively, younger patients and patients with greater severity injuries are more likely to undergo repair in the OR, and this was supported by our data. Overall, we found that primary repair of pediatric facial dog bite injuries, including complex soft-tissue injuries, is safe when performed in conjunction with antibiotic administration; however, further cross-specialty studies are needed to fully characterize these end points in a larger population.

Extensive facial trauma caused by dog bites in woman suffering from systemic fluconazole-resistant Candida infection.

INTRODUCTION: Dog bites present a complex problem. Extensive facial trauma is a challenging problem to treat with priority for functional outcome. This paper describes the conservative treatment in a very difficult case of facial trauma with unusual infections due to the bites. CASE REPORT: A 45 year-old woman was admitted in hypovolaemic shock with amputation of nose, upper and lower lips, left cheek and chin caused by dog bites. After vital parameters and volaemy were stabilized, wound toilet was performed, followed by skin and mucosal rotation flaps and anterior nasal tamponade; the lesion has then been covered with a collagen/oxidized regenerated cellulose dressing and sterile gauzes. Culture test highlighted coagulase-negative Staphylococcus and Candida albicans. However after few days, the patient developed septic-undulant hyperpyrexia, retinitis, renal candidiasis, folliculitis. Systemic Candida infection resistant to fluconazole was diagnosed. Amphotericin B was given to the patient and the facial wound was managed conservatively with an active medication because of inoperability conditions. The outcome of the use of active medications was an immediate response with excessive granulation tissue followed by a rapid re-epithelization. CONCLUSION: As our case has shown, conservative treatment can be a valid alternative therapy in the treatment of large wounds with invasive candidosis and candidaemia or other major contraindications to surgery. In fact, in cases where surgical reconstruction is not a feasible option, conservative treatment can allow a rapid repair of the skin barrier.

Trends in opioid prescription for craniomaxillofacial trauma in the United States: An 11-year retrospective study of emergency room and office visits.

BACKGROUND: Facial trauma is associated with significant long-term morbidity and pain. These patients are routinely prescribed opioid medication and are at risk for opioid dependence. Rates and trends in opioid prescription in the ambulatory setting for management of craniofacial trauma are unknown. METHODS: The National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey data were analyzed from 2006 to 2016. Using International Classification of Diseases codes, 7,997,454 visits for craniomaxillofacial trauma were identified. Trends in opioid and nonopioid prescriptions were studied, with variables of interest including demographics, geographic region, expected source of payment, and injury location. RESULTS: Over the study period, trends in both opioid and nonopioid prescriptions remained stable, with about 13.4% of all visits receiving opioid prescriptions. Patients aged 18 to 44 (P < .001) and lower face trauma (P = .047) were associated with increased rates, while Medicare and charity payers (P < .001) were associated with lower rates of opioid prescriptions. There was no significant difference in prescription rates across geographical regions, by ethnicity, or sex. CONCLUSION: Opioid medication forms the cornerstone for ambulatory management of craniofacial trauma. Despite increased awareness and emphasis on multimodal pain management, opioid prescription trends have remained relatively stable over time.

Explosive nasofacial cryptococosis.

Cryptococcal skin infection in persons with AIDS has been demonstrated. We describe a patient with nasal and facial infection with cryptococci after traumatic injury with battery acid.

[Injury following sodium hypochlorite irrigation during endodontic treatment]. / Letsel na irrigatie met natriumhypochloriet tijdens een endodontische behandeling.

A 58-year-old woman was referred by her dentist to a maxillofacial surgeon because of a rapidly increasing facial swelling. The swelling developed after sodium hypochlorite irrigation during the endodontic treatment of tooth 25. A mechanical heart valve, a heart rhythm disorder, and antithrombotic therapy were complicating medical conditions. Treatment consisted of 12 mg dexamethason administered once intravenously, augmentin administered thrice daily intravenously, and oral analgetics. Damage following sodium hypochlorite irrigation during endodontic treatment is a rare disorder which is associated with a severe reaction in the surrounding tissue. Damage can be permanent.

Facing the facts on prophylactic antibiotics for facial fractures: 1 day or less.

BACKGROUND: To evaluate the role of initial prophylactic antibiotics on facial fractures, outcomes were compared between a short course (≤24 hours) of antibiotics to those who received an extended course (>24 hours). METHODS: Adults admitted (2010-2015) to a Level I trauma center intensive care unit with at least one facial bone fracture and major injuries isolated to the head and neck were included. Our primary analysis compared infectious complications of the head or neck (H/N infection) between patients given short or extended courses of antibiotic prophylaxis. Multivariate logistic regression and analysis of propensity score matched pairs were performed. RESULTS: A total of 403 patients were included, 85.6% had blunt injuries and 72.7% had their facial fracture managed nonoperatively. The H/N infection rate was 11.2%. Two hundred eighty patients received a short course of antibiotics and 123 patients received an extended course. Median Injury Severity Score was 14 in both groups (p = 0.78). Patients receiving an extended course of antibiotics had higher rates of H/N infection (20.3% vs. 7.1%, p < 0.001). Factors associated with development of H/N infection included younger age, penetrating injury, open fracture, upper face or mandible fracture, fractures in multiple facial thirds, vascular injury, hypertension, and extended antibiotic course. Multivariate logistic regression identified younger age (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.96-1.00; p = 0.02), multiple facial third fractures (OR, 4.9; 95% CI, 2.4-10.2; p < 0.001), and penetrating mechanism (OR, 3.1; 95% CI, 1.5-6.4; p = 0.003) as independent predictors of H/N infection, but not antibiotic duration. Propensity score-matched analysis found no differences in H/N infection between short and extended antibiotic courses (11.4% vs. 12.5%; p = 1.0). Subgroup analyses demonstrated no differences in H/N infection between short or extended antibiotic courses by injury pattern, mechanism, or treatment (operative or nonoperative). CONCLUSION: These results lead us to believe that we should limit antibiotics to 24 hours or less upon admission for facial fractures. LEVEL OF EVIDENCE: Therapeutic/care management, level IV.

Botulinum toxin to improve facial wound healing: A prospective, blinded, placebo-controlled study.

OBJECTIVE: To test whether botulinum toxin-induced immobillzation of facial lacerations enhances wound healing and results in less noticeable scars. PATIENTS AND METHODS: In this blinded, prospective, randomized clinical trial, patients were randomized from February 1, 2002, until January 1, 2004, to botullnum toxin vs placebo injection into the musculature adjacent to the wound within 24 hours after wound closure. Blinded assessment of standardized photographs by experienced facial plastic surgeons using a 10-cm visual analog scale served as the main outcome measure. RESULTS: Thirty-one patients presenting with traumatic forehead lacerations or undergoing elective excisions of forehead masses were included in the study. The overall median visual analog scale score for the botulinum toxin-treated group was 8.9 compared with 7.2 for the placebo group (P=.003), indicating enhanced healing and Improved cosmesis of the experimentally immobilized scars. CONCLUSIONS: Botullnum toxin-induced Immobilization of forehead wounds enhances healing and is suggested for use in selected patients to improve the eventual appearance of the scar.

Ocular and facial injuries associated with the use of immersion heaters in an inmate population.

PURPOSE: To report ocular and facial injuries caused by the use of electric immersion heaters in an inmate population. DESIGN: Prospective observational case series. METHODS: Data were recorded over a six-month period on age, gender, mechanism of injury, examination, and treatment of Dallas County inmates who experienced ophthalmic injuries from immersion heaters and were referred to a tertiary-care center. RESULTS: Eight male inmates were treated for thermal ocular injuries, which occurred within jail cells as a result of cooking explosions from electric immersion heaters, known by inmates as "stingers." All patients had thermal eyelid burns, either first- or second-degree facial burns, and corneal abrasions with corneal edema. Corneal metallic foreign bodies were removed in one patient, and three patients underwent debridement for corneal sloughing. CONCLUSIONS: Immersion heater-related accidents may cause thermal injuries within the inmate population. Physicians evaluating incarcerated patients with ocular trauma should be aware of immersion heaters as a common cause.

Severe tissue damage and neurological deficit following extravasation of sodium hypochlorite solution during routine endodontic treatment.

Endodontic therapy is a routinely practised clinical procedure with few reported complications. Sodium hypochlorite is often used as an irrigant during this procedure, but severe complications may occur if this solution extravasates beyond the root apex. We present a case demonstrating some of the severe sequelae that can occur following the misuse of sodium hypochlorite during endodontic treatment of an upper lateral incisor, which also resulted in the previously unreported complication of isolated facial nerve weakness.

Management of partial thickness facial burns (comparison of topical antibiotics and bio-engineered skin substitutes).

This study compared the effect of standard topical antibiotic management versus a biological skin substitute wound closure for mid-partial thickness burns of the face. Adult patients with mid-dermal facial burns produced by flash flames or flame exposure were studied using a randomized prospective study design. Total daily burn care time, pain (0-10 scale) and healing time were monitored. Immediately after partial thickness debridement, the entire face burn, including ears, was closed with a bioengineered skin substitute coated with fibronectin (TransCyte) or treated by the open technique using bacitracin ointment applied 2-3 times daily. 21 patients were studied, with 10 patients in the skin substitute group. We found a significant decrease in wound care time 0.35 +/- 0.1 versus 1.9 +/- 0.5 h, decrease in pain of 2 +/- 1 versus 4 +/- 2 and re-epithelialization time 7 +/- 2 versus 13 +/- 4 days in the skin substitute group compared to topical antibiotics. We can conclude that a bioengineered skin substitute significantly improves the management and healing rate of partial thickness facial burns, compared to the standard open topical ointment technique.

A thermal burn to a prolapsed uterus.

Burns to the concealed area of the perineum, are relatively rare and usually associated with massive burns and a high mortality rate. A rare case of a thermal burn to a prolapsed uterus is described. The victim was a 72-year-old Bedouin woman, with a 70 per cent total body surface area deep burn from an open fire. In addition to the conventional treatment dictated by such a burn, two unique problems must be considered: (1) the common pathogens of the uterus, Neisseria gonorrhoeae, Chlamydia trachomatis and mycoplasma, are different from those of the skin; (2) the lymphatics of the uterus drain directly into the abdominal cavity and the risk of peritonitis and generalized infection is potentially higher. Intravenous, prophylactic, broad-spectrum antibiotics were therefore initiated immediately following admission. These included: cefoxitin, gentamicin and metronidazole a combination that covers both the potential pathogens of the uterus and the common pathogens of the skin. In addition, and for the same reason, Betadine substituted Flamazine for the local treatment of the exposed uterus. Our patient did not survive the burn, but in a similar, unusual case, the local and systematic remedies must protect against uterine pathogens that are not commonly seen in a burn victim.
