11/166. zinc burns: a rare burn injury.A patient was presented with significant burns resulting from a workplace accident in a zinc production unit. This occurred as a result of the spontaneous combustion of zinc bleed under high pressure. The patient sustained burns to the face, body, and hands and suffered significant injury to the left cornea. Computed imaging revealed solid particles in the ethmoid sinus and also in the right nasal fossa, dissecting the right lacrimal duct. Photographic documentation is presented. This injury was potentially preventable and resulted from poor observance of safety procedures.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
12/166. Bizarre paediatric facial burns.child abuse and neglect account for a significant number of paediatric burn injuries. It is of great importance because of the high mortality, high frequency of repeated abuse, as well as the physical, psychological and social sequelae that it causes. Burn abuse is often under-recognized and under-reported because it is difficult to define non-accidental injury. On the other hand, false accusation of burn abuse is extremely damaging to the family. Bizarre and unusual burn injuries can be caused by accident and should not automatically be assumed to be deliberate injury. Three boys of age 1-7 years with bizarre facial burns were admitted to the burns Unit at the Prince of wales Hospital between February 1995 and July 1999. One was burned by his baby-sitter with hot water steam and the other two were burned by their mothers with hot boiled eggs. The unusual causes of their burns raised the suspicion of child abuse and formal investigations were carried out by the Social Services Department. Detail assessment including a developmental history of the child and the psychosocial assessment of the family revealed that these three boys were burned because of poor medical advice and innocent cultural belief.- - - - - - - - - - ranking = 0.33333333333333keywords = injury (Clic here for more details about this article) |
13/166. Partial dislocation of laser in situ keratomileusis flap by air bag injury.PURPOSE: A patient developed significant corneal complications from air bag deployment, 17 months after laser in situ keratomileusis (LASIK). methods: Case report, slit-lamp microscopy, and review of the medical literature. RESULTS: A 37-year-old woman underwent bilateral LASIK with resultant 20/20 uncorrected visual acuity. Seventeen months later, she sustained facial and ocular injuries from air bag deployment during a motor vehicle accident. Examination revealed bilateral corneal abrasions, partial dislocation of the right corneal LASIK flap, and a hyphema in the right eye. The LASIK flap was realigned, but recovery was complicated by a slowly healing epithelial defect and flap edema. One month following the injury, epithelial ingrowth beneath the LASIK flap was noted. Surgical elevation of the flap and removal of the epithelial ingrowth was performed. Eight months later, epithelial ingrowth was absent and the visual acuity was 20/40. Residual irregular astigmatism necessitated rigid gas permeable contact lens fitting to achieve 20/20 visual acuity. CONCLUSIONS: air bags may cause significant ocular trauma. The wound healing response of LASIK allows corneal flap separation from its stromal bed for an indeterminate time after surgery. Discussion of the possible risk of corneal trauma as part of informed consent prior to LASIK may be appropriate.- - - - - - - - - - ranking = 0.83333333333333keywords = injury (Clic here for more details about this article) |
14/166. Healing of untidy traumatic skin defect of the face by secondary intention.BACKGROUND: Untidy facial skin defects manifest extensive soft tissue injury and contamination. Since modern surgical principles emphasize immediate wound closure, most surgeons should learn to convert an untidy wound to a tidy one and to reconstruct defects immediately if possible with the use of grafts and flaps. However, in some situations, healing by secondary intention remains advantageous. The purpose of this study is to reevaluate this traditional approach. methods: Twenty patients with untidy facial skin defects were treated conservatively over a 4-year period. The defects ranged from 2 x 2 cm2 to 6 x 4 cm2 in size. The depths of wounds were classified into partial-thickness in 9 patients, full-thickness in 7 patients, and deep defects in 4 patients. Each patient was instructed on wound care, which included daily cleaning with normal saline, followed by application of hydrocolloid occlusive dressing. Prophylactic antibiotics were not used. RESULTS: The mean follow-up period was 17 months. All wounds healed within 3 to 5 weeks. There was no wound infection. One patient developed a hypertrophic scar over the cheek, and received excision of the scar and resurfacing with full-thickness skin graft. Two patients had residual traumatic tattooing which was resolved by laser therapy. Two patients had hypopigmentation/hyperpigmentation problems. Most patients (18/20) were satisfied with both functional and cosmetic results. CONCLUSION: Conservative wound care with hydrocolloid occlusive dressing allows good healing by secondary intention for traumatic facial defects in selected patients.- - - - - - - - - - ranking = 0.16666666666667keywords = injury (Clic here for more details about this article) |
15/166. Temporoparietal fascial flap in orbital reconstruction.OBJECTIVE: To evaluate the success of the temporoparietal fascial flap (TPFF) in the primary or secondary reconstruction of difficult orbital defects and to review the surgical techniques. DESIGN: Retrospective analysis. SETTING: Tertiary medical center. patients: Nine patients with diverse orbital cavity or periorbital soft tissue and bony defects due to trauma, benign or malignant neoplasms, and radiation treatment. INTERVENTIONS: Temporoparietal fascial flap anatomy and techniques of harvest and inset are reviewed in detail. Four cases are presented to illustrate possible variables in orbital reconstruction. Variables examined include the location of defects, the success of flap survival in orbital cavities after primary or secondary reconstruction, the effects of prior irradiation on flap survival, and the possibility of concurrent osteointegrated implant placement with TPFF reconstruction. MAIN OUTCOME MEASURES: Functional and aesthetic outcomes were determined by physical examination and preoperative and postoperative photographs. RESULTS: All patients had successful transfer of TPFF grafts without flap compromise. Temporoparietal fascial flap was a viable option for subtle orbital and malar contour defects. In chronically inflamed wounds such as with osteoradionecrosis and orbitoantral fistula, TPFF successfully restored vascularity, obliterated the defects, and enabled the placement of osteointegrated implants. The TPFF also supported the concurrent placement of a free calvarial bone graft. Finally, split-thickness skin grafted onto a pedicled TPFF showed 100% survival. CONCLUSIONS: The TPFF is one of the most reliable and versatile regional flaps in the head and neck for orbital reconstruction. This study presents the use of TPFF in a variety of orbital defects, from lateral bony rim defects to total exenteration. Timing of repair in this study spans from immediate reconstruction to reconstruction delayed more than 50 years after the initial injury. In all cases, reconstruction with TPFF resulted in improved bony and soft tissue contours, and incurred minimal morbidity.- - - - - - - - - - ranking = 0.16666666666667keywords = injury (Clic here for more details about this article) |
16/166. Matching tire tracks on the head using forensic photogrammetry.In the field of the documentation of forensics-relevant injuries, from the reconstructive point of view, the forensic, CAD-supported photogrammetry plays an important role; particularly so when a detailed 3-D reconstruction is vital. This is demonstrated with a soft-tissue injury to the face caused by being run over by a car tire. Since the objects (injury and surface of the tire) to be investigated will be evaluated in virtual space, they must be series photographed. These photo sequences are then evaluated with the RolleiMetric multi-image evaluation system. This system measures and calculates the spatial location of points shown in the photo sequences, and creates 3-D data models of the objects.In a 3-D CAD program, the model of the injury is then compared against the model of the possible injury-causing instrument.The validation of the forensic, CAD-supported photogrammetry, as shown by the perfect 3-D match between the tire tread and the facial injury, demonstrates how greatly this 3-D method surpasses the classic 2-D overlay method (one-to-one photography).- - - - - - - - - - ranking = 0.83333333333333keywords = injury (Clic here for more details about this article) |
17/166. Intubating LMA guided awake fibreoptic intubation in severe maxillo-facial injury.PURPOSE: To describe control of the airway in a patient with severe maxillo-facial injury using intubating laryngeal mask guided awake fibreoptic intubation. CLINICAL FEATURES: A 110 kg man presented with a severe facial injury due to a horse kick. Local examination showed a large transverse gaping laceration just beneath the nose, exposing the lower nasal cavities through to the posterior nasopharynx. It was planned to perform a surgical tracheostomy before surgical fixation of the maxilla and nasal bones. Considering the patient's weight, short neck and difficulty in lying flat, surgical tracheostomy under general anesthesia was considered the best option. Under topical anesthesia, an intubating laryngeal mask was introduced followed by a fibreoptic bronchscope. The endotracheal tube was threaded over the bronchoscope and airway control achieved. CONCLUSIONS: The use of an intubating laryngeal mask avoids the need for manipulation of the head and neck and acts as a 'shield' for the fibreoptic bronchoscope from surrounding blood in patients with maxillo-facial injury. The use of the fibreoptic bronchoscope ensures intubation under vision.- - - - - - - - - - ranking = 1.1705455850194keywords = injury, laceration (Clic here for more details about this article) |
18/166. death caused by a letter bomb.A 48-year-old man was killed by the explosion of a letter bomb after receiving severe injuries to his face and left hand. The autopsy ascertained that the right eye and orbit had been completely destroyed by a large piece of metal from a tin can that had entered the cranial cavity through the right eye and caused fatal brain damage. The victim had also sustained a severe injury to his left hand. Reconstruction of the metal and plastic fragments showed that the victim had received a padded envelope with a video cassette in which a simple explosive device was hidden in a flat tin. The explosive charge consisted of a mixture (ca. 60 g) of sodium chlorate, sodium chloride and sucrose. The charge was detonated by a nylon cord attached to the inside of the envelope which was stretched when the video cassette was pulled out of the envelope. This removed a piece of plastic from between two contacts, and the explosion was set off immediately by a battery which activated two flash bulbs placed within the charge.- - - - - - - - - - ranking = 0.16673167009664keywords = injury, brain (Clic here for more details about this article) |
19/166. Effect of facial pressure garments for burn injury in adult patients after orthodontic treatment.pressure garments are commonly used to prevent and control hypertrophic scar tissue. Complications are unusual, though in children with facial burns, pressure garments may lead to skeletal and dental deformities. Studies in adolescents and adults are sparse. We describe a 24-year-old woman who sustained facial burns. Prior to injury, the patient had undergone premolar extraction in preparation for orthodontic treatment. Her post-burn care consisted of application of a Jobst pressure garment. After 2 months treatment, severe deformation of the dental-alveolar structure was observed. This reports suggests that adults after dental extraction are at a high risk of dental-alveolar deformities from pressure garments and might benefit from the use of occlusal wafers.- - - - - - - - - - ranking = 0.83333333333333keywords = injury (Clic here for more details about this article) |
20/166. Walk-through injuries: glass door facial injuries.During 1998, 13 patients were treated in the Tel-Aviv Sourasky Medical Center for complex facial soft-tissue injuries caused by passing through large, clear glass doors. All epidemiological details were gathered and analyzed. Of 1,100 soft-tissue facial injury admissions in 1 year, 13 patients had a substantial soft-tissue facial injury after passing through a glass barrier. Nine were injured during leisure time activity, five in a shopping mall, and four in their residence. Interestingly, the authors found a common pattern of facial injuries in all patients. It consisted of large, irregular, composite skin and soft-tissue flaps as well as large, tom, irregular skin lacerations. The nose was injured predominantly, and the injury was particularly complex. Their recommended management of these injuries is a thorough and careful evaluation of flap viability. Surgical management of avulsed, viable flaps includes margin debridement and repositioning. If the flap is narrow enough, it can be debrided and the margins adapted primarily. If viability of part of the flap is in doubt, that part should be debrided and used as a composite graft. When this graft dies, a full-thickness graft is taken from another facial site. The cosmesis of such a graft is better than using the debrided, thin segment as a skin graft that is too thin. The authors emphasize that there is a need to encourage authorities to reinforce regulations relating to injury prevention from architectural glass. The first is to use special glazing, either tempered glass, laminated glass, or both. The other method of improving safety is by indicating glass using decorations or warning stickers, or by making it partly translucent. Unless these regulations are obeyed, fatal or complex trauma may occur.- - - - - - - - - - ranking = 0.67054558501944keywords = injury, laceration (Clic here for more details about this article) |
