1/211. Growing skull fracture of the orbital roof. Case report.Growing skull fractures are rare complications of head trauma and very rarely arise in the skull base. The clinical and radiological finding and treatment of a growing fracture of the orbital roof in a 5-year-old boy are reported, and the relevant literature is reviewed. The clinical picture was eyelid swelling. Computed tomography (CT) scan was excellent for demonstrating the bony defect in the orbital roof. Frontobasal brain injury seems to play an important role in the pathogenesis of the fracture growth. Growing skull fracture of the orbital roof should be considered in the differential diagnosis in cases of persistent ocular symptoms. craniotomy with excision of gliotic brain and granulation tissue, dural repair and cranioplasty is the treatment of choice.- - - - - - - - - - ranking = 1keywords = injury, brain injury, trauma, brain (Clic here for more details about this article) |
2/211. Acute orbital compartment syndrome after lateral blow-out fracture effectively relieved by lateral cantholysis.PURPOSE: To report the observation of an acute traumatic orbital compartment syndrome in an 80-year-old man. methods: Lateral canthotomy and cantholysis. Computed x-ray tomography. RESULTS: Unilateral proptosis, blindness, a frozen globe and a dilated pupil developed within one hour after a blunt trauma to the left orbital region. Surgery two hours later resulted in normal orbital tension and near-complete recovery of functions. An orbital hematoma was found overlying a lateral blow-out fracture. CONCLUSION: Under favorable conditions, the orbital compartment syndrome can be effectively relieved by lateral canthotomy and cantholysis. The present and previous reports suggest that two hours of orbital ischemia is near the critical time limit for recovery of full visual function.- - - - - - - - - - ranking = 0.16529395530379keywords = trauma (Clic here for more details about this article) |
3/211. Less common orbital fracture patterns: the role of computed tomography in the management of depression of the inferior oblique origin and lateral rectus involvement in blow-in fractures.During the past decade, advances in radiographic imaging have made it possible for the surgeon managing orbital fractures to adopt a rational therapeutic strategy based on a knowledge of alterations in surgical anatomy secondary to traumatic injury. To illustrate the value of computed tomography in the surgeon's armamentarium for management of orbital fractures, cases are presented in which imaging proved decisive in planning a course of therapy. Two patients presented with two types of isolated lateral blow-in fracture, an uncommon fracture pattern. The other cases underscore the value of defining involvement of the inferior oblique origin and lateral rectus muscles in imaging complex orbital fractures, issues not emphasized in earlier literature. Although diplopia alone does not always warrant surgical intervention, diplopia in the context of computed tomography-defined muscle entrapment or muscle origin displacement justifies operative therapy. These cases demonstrate the value of computed tomography in directing surgical therapy with resolution of diplopia and prevention and correction of enophthalmos.- - - - - - - - - - ranking = 0.53229019173159keywords = injury, trauma (Clic here for more details about this article) |
4/211. CSF orbitorrhoea with tension pneumocephalus.A seventy eight year old man sustained penetrating injury to right orbit about 15 years ago. Later he developed right orbital infection leading to phthisis bulbi. Two months before admission he developed CSF leak from the right orbit, tension pneumocephalous and meningitis. A rare case of CSF orbitorrhoea is reported here along with the discussion on mechanisms and management.- - - - - - - - - - ranking = 0.4496432140797keywords = injury (Clic here for more details about this article) |
5/211. Long-term sequelae after surgery for orbital floor fractures.A surgical technique involving exact repositioning and rigid fixation is required for the reduction of fractures of the orbital floor. Even then, sequelae may be present long after the trauma. The aim of this study was to establish the frequency and type of sequelae after surgery for orbital floor fractures and to investigate the extent to which the method of surgery had any impact on the severity of the sequelae. A questionnaire was sent to all 107 patients (response rate 77%) 1 to 5 years after the injury. Further clinical data were obtained from the patients' charts. Eighty-three percent of the patients were affected by some kind of permanent sequelae in terms of sensibility, vision, and/or physical appearance. A high frequency of diplopia (36%) was related to the reconstruction of the orbital floor with a temporary "supporting" antral packing in the maxillary sinus, a technique which has now been abandoned at our department in favor of orbital restoration with sheets of porous polyethylene. Our conclusion is that, because long-term sequelae are common, the surgical technique must be subjected to continuous quality control to minimize future problems for this group of patients.- - - - - - - - - - ranking = 0.53229019173159keywords = injury, trauma (Clic here for more details about this article) |
6/211. Repair of orbital floor fractures with hydroxyapatite block scaffolding.PURPOSE: To determine the efficacy of using a scaffold of hydroxyapatite blocks within the maxillary sinus to treat patients with large orbital floor fractures and secondary vertical globe dystopia. methods: Case series of five patients. Hydroxyapatite blocks were stacked within the maxillary antrum to support the reconstructed orbital floor. RESULTS: All patients had good results, though mild residual enophthalmos persisted in three patients. The orbital floor implants and globe positions remained stable during follow-up intervals ranging from 46 to 65 months. No adverse postoperative complications, such as sinusitis, developed. CONCLUSIONS: Hydroxyapatite block scaffolding is a useful alternative to metallic floor implants and autologous bone grafts in the reconstruction of large traumatic orbital floor defects associated with vertical globe dystopia.- - - - - - - - - - ranking = 0.082646977651894keywords = trauma (Clic here for more details about this article) |
7/211. Management of traumatic luxation of the globe. A case report.PURPOSE: To report the management of a patient who had LeFort type III fractures and traumatic luxation of the globe with avulsion of the optic nerve and all extraocular muscles except for the medial rectus. methods: Eight hours after the trauma, the detached and retracted superior and lateral recti muscles could be found and sutured to their original insertions. The inferior rectus could not be retrieved. RESULTS: Although the left eye had no light perception, most of its motility was restored resulting in an unblemished cosmesis. CONCLUSION: Avoiding primary enucleation helped to alleviate the psychological burden of the trauma on the patient. In case of the eventual development of phthisis bulbi, the patient will have a chance to be fitted with a prosthesis over his own eye with a resulting better motility.- - - - - - - - - - ranking = 0.57852884356326keywords = trauma (Clic here for more details about this article) |
8/211. Bilateral simultaneous optic nerve dysfunction after periorbital trauma: recovery of vision in association with with chiropractic spinal manipulation therapy.OBJECTIVE: To discuss the recovery of optic nerve function after chiropractic spinal manipulation in a patient with loss of vision as a result of facial fracture from a fall. CLINICAL FEATURES: In a fall down a stairwell, a 53-year-old woman with migraines fractured her right zygomatic arch, which was later treated surgically. Approximately 3 weeks after the accident, vision in her contralateral eye became reduced to light perception. Electrophysiologic studies revealed that the function of both optic nerves was diminished, the right significantly more than the left. Single photon emission tomography showed pancerebral ischemic foci. INTERVENTION AND OUTCOME: chiropractic spinal manipulation was used to aid recovery of vision to normal over a course of 20 treatment sessions. At times, significant improvement in vision occurred immediately after spinal manipulation. Progressive recovery of vision was monitored by serial visual field tests and by electrophysiologic studies. Unfortunately, the patient refused a further single photon emission tomographic study when visual recovery was complete. CONCLUSION: This case report adds to previous accounts of progressive and expeditious recovery of optic nerve function in association with spinal manipulation therapy.- - - - - - - - - - ranking = 0.33058791060757keywords = trauma (Clic here for more details about this article) |
9/211. Traumatic optic neuropathy. A case report.A case of visual loss following cranio-maxillofacial trauma is reported. The patient had a sudden partial blindness associated with a fracture of the roof, medial and lateral orbital walls. Access to the orbit was achieved through a transethmoidal approach using the Howarth-Lynch medial incision and resecting the bone fragments which impinged on the optic nerve. The patient had total return of visual acuity, without surgical complications. The role of orbital and optic decompression in the management of patients with traumatic optic neuropathy is discussed. Its indications are controversial and the procedure should be considered only within the context of the specific needs of the individual patient.- - - - - - - - - - ranking = 0.16529395530379keywords = trauma (Clic here for more details about this article) |
10/211. Missed orbital wall blow-out fracture as a cause of post-enucleation socket syndrome.BACKGROUND: Post-enucleation socket syndrome (PESS: deep upper lid sulcus, ptosis or upper lid retraction, enophthalmos and lower lid laxity) is a well-recognised complication of a volume-deficient anophthalmic socket. A patient requiring enucleation following severe ocular trauma may have an underlying orbital wall blow-out fracture which if overlooked can cause severe volume deficit with poor cosmesis and limited prosthesis motility. PURPOSE: To establish the prevalence of an undiagnosed blow-out fracture in patients with PESS and a history of relevant trauma. methods: medical records and orbital computed tomography (CT) scans were reviewed for all patients presenting with PESS and a history of relevant trauma. RESULTS: Undiagnosed blow-out fractures were found in 15 (33%) of 45 patients presenting between August 1993 and December 1996. These were significant enough to warrant surgical repair in 13 (29%) patients. CONCLUSIONS: We suggest that any patient presenting with PESS and a history of relevant trauma should be considered to have an orbital wall blow-out fracture until proven otherwise by CT scanning of the orbit. Similarly any patient requiring enucleation following severe ocular trauma should undergo CT scanning to rule out a coexisting blow-out fracture which could be repaired at the time of enucleation.- - - - - - - - - - ranking = 0.41323488825947keywords = trauma (Clic here for more details about this article) |
