1/64. A complication of intraoperative facial nerve monitoring: facial skin burns.OBJECTIVE: To report on three cases of severe facial skin burns resulting from intraoperative facial nerve monitoring in patients undergoing parotidectomies. STUDY DESIGN: This study is a retrospective case review. SETTING: A tertiary referral center. patients: This study includes three patients who underwent parotidectomies with concurrent facial nerve monitoring. RESULTS: Facial skin burns were proven to result from a technical defect of the intraoperative facial nerve monitoring device. burns were sustained at electrode insertion sites and their extent was related to the duration of monitoring. The most probable explanation of these burns is electrolysis. CONCLUSIONS: Successful retracing of technical defaults with biomedical engineers at the device manufacturer have led to the upgrade of the facial nerve monitor apparatus. The benefits of facial nerve monitoring largely outweigh the fortuitous occurrence of skin burns reported in this study. Therefore, this complication should not represent a drawback to the use of facial nerve monitoring.- - - - - - - - - - ranking = 1keywords = back (Clic here for more details about this article) |
2/64. skin and soft tissue artifacts due to postmortem damage caused by rodents.Five cases of postmortem bite-injuries inflicted by rodents are presented (five males between 41 and 89 years; three cases caused by mice, one case by rats, one case of possible mixed rodent activity by rats and mice). The study presents a spectrum of phenomenological aspects of postmortem artifacts due to rodent activity to fresh skin and soft tissue: the majority of the injuries have a circular appearance. The wound margins are finely serrated with irregular edges and circumscribed 1-2 mm intervals within, partly showing protruding indentations up to 5 mm. Distinct parallel cutaneous lacerations deriving from the biting action of the upper and lower pairs of the rodents incisors are diagnostic for tooth marks of rodent origin but cannot always be found. No claw-induced damage can be found in the skin beyond the wound margins. Areas involved in the present study were: exposed and unprotected parts of the body, such as eyelids, nose and mouth (representing moist parts of the face); and the back of the hands. Postmortem rodent activity may occasionally be expected on clothed and therefore protected parts of the body. The phenomenon of postmortem rodent activity to human bodies can be found indoors especially under circumstances of low socioeconomic settings; outdoors this finding is particularly observed among fatalities among homeless people.- - - - - - - - - - ranking = 27.644257494751keywords = upper, back (Clic here for more details about this article) |
3/64. 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 = 26.644257494751keywords = upper (Clic here for more details about this article) |
4/64. Traumatic pneumomediastinum caused by isolated blunt facial trauma: a case report.Traumatic pneumomediastinum is most often identified as an incidental finding in the setting of blunt or penetrating neck, chest, or abdominal trauma. There are only a few cases in the medical literature of a pneumomediastinum following isolated facial trauma. We present a patient who sustained fractures of the lateral and anterior walls of the right maxillary sinus, floor of the right orbit, and right zygomatic arch. subcutaneous emphysema overlaid the right facial region and extended to the left side of the neck and into the mediastinum. We describe this unusual complication with respect to the anatomic relations of the facial and cervical fascial planes and spaces with the mediastinum.- - - - - - - - - - ranking = 4.8387172861648keywords = chest (Clic here for more details about this article) |
5/64. The use of pedicled expanded flaps for aesthetic resurfacing of the burned face.Reconstruction of extensive, deep burns of the face is a challenging problem in plastic surgery. The authors report the use of tissue expanders placed in the upper chest for facial resurfacing after burn injuries in 4 patients. The expanders are hyperinflated. The flap is then advanced upward to resurface an aesthetic unit of the face with the pedicle intact. The pedicle is divided 2 weeks later. The method of reconstruction allows a large area of facial resurfacing to be performed without fear of flap loss or flap retraction impairing the cosmetic result. This technique has the disadvantage of being a staged procedure and cannot be performed in those with burns of the upper chest.- - - - - - - - - - ranking = 62.965949561832keywords = upper, chest (Clic here for more details about this article) |
6/64. Botulinum toxin to minimize facial scarring.Botulinum toxin injection has been used for a variety of indications in humans, including blepharospasm and hyperfunctional facial lines. This article describes a novel formulation of botulinum toxin, which supplies immediate feedback to the injecting physician. Additionally, recent findings are described that indicate the immediate injection of botulinum toxin into the muscles underlying a wound can improve the cosmetic outcome of the facial cutaneous scar. Future applications of these findings are discussed.- - - - - - - - - - ranking = 1keywords = back (Clic here for more details about this article) |
7/64. Craniofacial trauma in children.Craniofacial trauma is relatively uncommon in children, but the potential involvement of the structures at the base of the skull and the intracranial space makes it important for physicians to understand the potential dangers presented by such injuries. This report delineates the different types of injury that can damage the upper facial skeleton and the brain of a child. The author reviews initial management and diagnosis of such injuries and examines the approach to definitive reconstructive surgery using three case studies as examples for discussion.- - - - - - - - - - ranking = 26.644257494751keywords = upper (Clic here for more details about this article) |
8/64. The bicoronal flap approach in craniofacial trauma.The utilization of the bicoronal scalp flap in craniofacial trauma has proved indispensable in the management of severe craniofacial injuries. It provides vast exposure of such critical structures as the cranium, frontal sinus, orbit and upper midface, compared with that for previous techniques of facial fracture reduction. Although the flap has great utility, severe complications, such as facial nerve injury, diplopia, telecanthus, and scalp necrosis, can occur. This article reviews the surgical anatomy, technique, and indications for the safe utilization of the bicoronal scalp flap approach in the management of craniofacial trauma.- - - - - - - - - - ranking = 26.644257494751keywords = upper (Clic here for more details about this article) |
9/64. Fatal bacteria granuloma after trauma: a new entity.In the past 20 years, more than 20 cases of a type of granulomatous disease have been noticed by dermatologists in different areas of china. The patients had these features in common: (i) the lesions followed a slight trauma to the face; (ii) they were spreading dark-red plaques without pus or ulceration; (iii) new lesions appeared near to or far from the original lesion; (iv) histopathology showed histiocytic granuloma; (v) the patients had severe headache and clouding of consciousness during the later stages of the disease; (vi) all patients died within 1.5-4 years; (vii) treatment with prednisone led to some healing of the lesions but accelerated death; and (viii) all patients were from rural areas. We examined the tissues from two similar patients by electron microscopy and identified two kinds of bacteria as a possible cause of the disease. One was an anaerobic actinomycete, the other was staphylococcus capitis. The anaerobic actinomycete was sensitive to lincomycin (a forerunner of clindamycin). After a 5-month therapy with lincomycin, one patient survived. We infer that the cause of death is the unknown anaerobic actinomycete. Because the disease is very severe, we suggest the name 'fatal bacteria granuloma after trauma' to draw attention.- - - - - - - - - - ranking = 12.372754974543keywords = headache (Clic here for more details about this article) |
10/64. Prefabricated galeal flap based on superficial temporal and posterior auricular vessels.scalp layers are widely used in reconstructive procedures. The authors used prefabricated galeal flaps based on the superficial temporal or postauricular vessels for ear, cheek, mandible, and cranium reconstructions in three cases. In case 1, synchronous beard and ear reconstructions were accomplished by using the temporoparietal and retroauricular flaps. In case 2, a buccomandibular defect was reconstructed by transposing the supra-auricular and retroauricular galea with prefabricated bone and skin. In case 3, an epidural hematoma in the left frontoparietal area was evacuated after a circular craniectomy. The harvested bone was not put back on the defect area but buried between the periosteal and galeal layers because of brain edema. These layers were raised as an osteogaleoperiosteal flap and transposed onto the defect area after 7 weeks. When used with a prefabrication method, scalp layers offer versatile options for repairing composite defects of the head region. A galeal flap based on the posterior auricular vessels is practical and reliable in reconstructive procedures. The authors suggest that this flap is an option in cases in which the temporoparietal fascia artery or the superficial temporal artery is not available. Prefabrication of the harvested cranial bone inside the adjacent tissues offers several advantages in that a viable bone is provided at the end of the procedure, intervention at a distant area is avoided, the graft is placed on osteogenic tissue (periosteum) that is also transposed onto the defect, and sophisticated procedures such as microsurgical techniques are not needed.- - - - - - - - - - ranking = 1keywords = back (Clic here for more details about this article) |
