1/152. microstomia following facial burns.Deep burns to the face and lips often lead to the formation of scar tissue and contracture of the perioral tissues with marked reduction of the ability of the patient to open his mouth. The mouth tends to be turned into a wrinkled, rigid, unyielding structure, resembling the semi-rigid mouth of the fish. Such burns are most frequently caused by electricity or flames, and less frequently by chemical substances. The deformity caused by microstomia is painful both to the patient and to his family. Additionally, there is serious functional loss, it is practically impossible to smile, speech becomes difficult, and the movement of the mandible is limited. In severe cases feeding has to be performed with a straw. oral hygiene is compromised and access for the administration of dental care is impossible, hence limited to extractions. Techniques to prevent or, if not prevented, surgically correct the resultant microstomia are described, followed by a case report on a pediatric patient, whose microstomia was surgically corrected several years following the injury.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
2/152. Some missile injuries due to civil unrest in northern ireland.Some missile injuries are reviewed after nearly 8 years of continuous warfare. A feature of many of these injuries is the early admission to hospital which has had a profound effect on the survival rate and the recovery period. Some examples are given of injuries inflicted by rubber bullets. The effects of wounding by low and high velocity missiles are described and examples given. An injury caused by a missile incorporated in a bomb is also shown.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
3/152. death due to concussion and alcohol.We encountered 5 deaths following blunt trauma to the face and head in which the injuries were predominantly soft tissue in nature with absence of skull fractures, intracranial bleeding, or detectable injury to the brain. All individuals were intoxicated, with blood ethanol levels ranging from 0.22 to 0.33 g/dl. We feel that in these deaths, ethanol augmentation of the effects of concussive brain injury, with resultant posttraumatic apnea, was the mechanism of death.- - - - - - - - - - ranking = 2keywords = injury (Clic here for more details about this article) |
4/152. Extensive facial damage caused by a blast injury arising from a 6 volt lead accumulator.Low-voltage electrical injuries are relatively uncommon. Injury caused by flow of heavy current due to short-circuiting a low-voltage battery has not been described in the English literature. A 9-year-old boy connected two thin household electrical wires to the two terminals of a 6 volt (lead accumulator) battery and pressed the other two ends between his teeth. This resulted in a blast causing a compound comminuted fracture of the mandible and extensive tissue damage in the oral cavity. The low internal resistance of a lead accumulator (approximately 0.03 ohms) permits the flow of a heavy current (approximately 200 amps) when short-circuited. This instantaneously vaporises a minuscule portion of wire at approximately 2000 K resulting in a sudden rise of intraoral pressure to 30 kg cm-2 leading to tissue damage.- - - - - - - - - - ranking = 4keywords = injury (Clic here for more details about this article) |
5/152. Chain saw injury of the mandibulofacial region.Use of chain saws is hazardous. Public understanding of the hazards and of modern types of chain saws will eventually help in preventing these injuries. An injury of the mandibulofacial region resulting from a chain saw has been described with special emphasis on preoperative, intraoperative, and postoperative management.- - - - - - - - - - ranking = 5keywords = injury (Clic here for more details about this article) |
6/152. Experience with regional flaps in the comprehensive treatment of maxillofacial soft-tissue injuries in war victims.This article presents our experience with regional flaps in the treatment of facial soft-tissue defects and deformities in 33 patients with various facial injuries from warfare during the period from 1986 to 1999. Thirty-two males and 1 female aged between 8 and 53 years (mean 24.18 years) were treated with facial soft-tissue injuries from high velocity projectiles and varying degrees of associated hard-tissue injuries. Bullets were the most common cause (70%), followed by injuries from shrapnel (21%), land mines (6%), and breech blocks (3%). The perioral region was involved in 15 cases (45%), the midface and cheeks were involved in 13 cases (39%), and the periorbital area was involved in 5 cases (15%). All soft-tissue injuries were treated primarily by debridement and primary closure and by combining, modifying, and tailoring standard regional flap techniques to fit the location of the injury and compensate for the extent of tissue loss. These procedures consisted basically of local-advancement or rotation-advancement flaps, used in conjunction with pedicled fat or subcutaneous supporting flaps, nasolabial, cheek, cervical, Dieffenbach, and Abbe-type flaps. Scar revision, tissue repositioning, and lengthening procedures, such as W, V-Y, Z, or multiple Z-plasty techniques were also used both primarily and secondarily. Revisions and secondary operations were done in 48% of the patients. Initial healing of the flaps was favourable in 76% of the patients. Postoperative discharge from the suture sites was seen in 24% of the patients, but this usually resolved within several weeks using daily irrigation, and these cases underwent scar revision subsequently. None of the soft-tissue flaps sloughed or developed necrosis. Form and function of the soft-tissue reconstructed regions usually recovered within one year postoperatively. The aesthetic results obtained were favourable. None required facial nerve grafting as only the terminal branches were injured in our cases and functional recovery was acceptable. Application of local tissue transfer procedures in our series of facial warfare injuries yielded acceptable tissue form, texture, and colour match, especially when these procedures were used in combination, and tailored to surgically fit the individual case. Moreover, application of these procedures is relatively easy and postoperative morbidity is limited, provided the general condition of the patient is stable, and the surgical techniques used have good indications and flap principles.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
7/152. Unusual parotid gland foreign body.A foreign body in the parotid gland whether from the oral cavity or through the skin is extremely uncommon. A case is described of the tip of a golden-colored pencil accidentally piercing the deep lobe after a fall. Emergency surgical removal was performed, and the diagnosis of the foreign body was quite easy. In contrast, determination of the location in the gland had to be done by a microscope, with fluoroscopy during the operation and was quite difficult. During removal, great attention was paid to avoiding facial nerve injury. This was done by identifying the facial trunk at the pointer using a microscope. The dissolved material including copper and zinc metal powder, paste, and clay, was found in the deep lobe associated with the surrounding abscess. Although these materials are assumed to be harmless to human tissues, the complete and immediate removal is to prevent salivary fistule resulting from inflammation.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
8/152. Total eyelid reconstruction with free dorsalis pedis flap after deep facial burn.A case of severe facial and corneal burns with complete loss of upper and lower eyelids is reported together with the acute management and surgical options for total eyelid defects secondary to thermal injury. An acutely burned man with 78 percent total burn surface area presented with complete exposure of the left cornea. Because of the severe thermal injury, no facial tissues were available as donor sources for reconstructing the eyelid. A free dorsalis pedis flap was used to cover the exposed cornea after bilateral conjunctival advancement flaps, with septal cartilage graft for structural support. A conjunctivodacryocystorhinostomy was performed at the time of the coverage. The patient was unable to perform an exact visual acuity test; however, his gross vision was intact.- - - - - - - - - - ranking = 2keywords = injury (Clic here for more details about this article) |
9/152. Sevoflurane mask anesthesia for urgent tracheostomy in an uncooperative trauma patient with a difficult airway.PURPOSE: Proper care of the trauma patient often includes tracheal intubation to insure adequate ventilation and oxygenation, protect the airway from aspiration, and facilitate surgery. airway management can be particularly complex when there are facial bone fractures, head injury and cervical spine instability. CLINICAL FEATURES: A 29-yr-old intoxicated woman suffered a motor vehicle accident. Injuries consisted of multiple abrasions to her head, forehead, and face, right temporal lobe hemorrhage, and complex mandibular fractures with displacement. mouth opening was <10 mm. blood pressure was 106/71 mm Hg, pulse 109, respirations 18, temperature 37.3 degrees C, SpO2 100%. Chest and pelvic radiographs were normal and the there was increased anterior angulation of C4-C5 on the cervical spine film. Drug screen was positive for cocaine and alcohol. The initial plan was to perform awake tracheostomy with local anesthesia. However, the patient was uncooperative despite sedation and infiltration of local anesthesia. Sevoflurane, 1%, inspired in oxygen 100%, was administered via face mask. The concentration of sevoflurane was gradually increased to 4%, and loss of consciousness occurred within one minute. The patient breathed spontaneously and required gentle chin lift and jaw thrust. A cuffed tracheostomy tube was surgically inserted without complication. Blood gas showed pH 7.40, PCO2 35 mm Hg, PO2 396 mm Hg, hematocrit 33.6%. Diagnostic peritoneal lavage was negative. Pulmonary aspiration did not occur. Oxygenation and ventilation were maintained throughout the procedure. CONCLUSION: Continuous mask ventilation with sevoflurane is an appropriate technique when confronted with an uncooperative trauma patient with a difficult airway.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
10/152. 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 = 6keywords = injury (Clic here for more details about this article) |
