Barotraumatic blowout fracture of the orbit after sneezing: Cone beam CT demonstration.
2018
A 40-year-old man with no history of trauma or previous sinus surgery complained sudden right diplopia after vigorous sneezing. The patient was submitted elsewhere to a MRI study for persisting diplopia, with inconclusive findings. One week later the patient was submitted to a maxillofacial cone beam CT (CBCT) in our Institution. A blowout fracture of the right orbital floor and lateral orbital wall with an intact orbital rim and a ipsilateral maxillary sinus effusion with an air liquid level, were detected at the CBCT study. Our conclusion, confirmed by the clinician, was the patient had a barotraumatic, isolated, pure blowout fracture of the right orbit consequence of the episode of vigor…
Three-dimensional distribution of trabecular bone density and cortical thickness in the distal humerus
2008
One major barrier to osteosynthesis in distal humeral fractures is poor bone quality. This study was an attempt to measure the bone quality in the distal humerus.We measured the distribution of total bone mineral density (BMD), trabecular BMD (tBMD), and cortical thickness (CTh) in the distal humerus using peripheral quantitive computed tomography. Four slices in the infracondylar, supracondylar, and distal disphyseal regions of 25 human cadaver humeri were investigated.Total BMD decreased continuously from the distal diaphysis to the trochlea. Within the infracondylar region, the capitellum was the region of lowest tBMD and CTh (P.001). Measurements in anterior regions were higher than in …
Optic nerve decompression in trauma and tumor patients
1999
Optic nerve decompression is a procedure that is now receiving increasing clinical attention. However, there are currently no standardized treatment protocols in the therapy of traumatic or pressure insults to the nerve. The present retrospective study was designed to report our experience with microscopic endonasal transethmoid-sphenoid optic nerve decompression in 24 unilateral trauma cases and 11 unilateral skull base tumor patients. In general preoperative visual acuities in the trauma patients were worse than in the tumor patients. Following surgery, 9 of 11 tumor patients (82%) had at least some improvement of their vision, including 5 complete recoveries. In the group with traumatic …
A novel minimally invasive, dorsolateral, tubular partial odontoidectomy and autologous bone augmentation to treat dens pseudarthrosis: cadaveric, 3D…
2017
OBJECTIVE The goal of this study was to demonstrate the clinical and technical nuances of a minimally invasive, dorsolateral, tubular approach for partial odontoidectomy, autologous bone augmentation, and temporary C1–2 fixation to treat dens pseudarthrosis. METHODS A cadaveric feasibility study, a 3D virtual reality reconstruction study, and the subsequent application of this approach in 2 clinical cases are reported. Eight procedures were completed in 4 human cadavers. A minimally invasive, dorsolateral, tubular approach for odontoidectomy was performed with the aid of a tubular retraction system, using a posterolateral incision and an oblique approach angle. Fluoroscopy and postprocedur…
Changes in anatomic position of root canal orifices in pluriradicular teeth following re-location during endodontic treatment
2017
Abstract Direct access to the root canals in posterior teeth for endodontic treatment is most frequently facilitated by the straightening of the coronal parts of the root canals, having as a consequence the relocation of the canal orifices on the map of the floor of the pulp chamber ( Christie and Thompson, 1994 ). This procedure intentionally moves the coronal aspect of a canal away from the center of the chamber, while simultaneously removing internal dentin from the pulp chamber walls. The aim of this study was to evaluate the displacement resulting from the relocation of root canal orifices during the initial phase of rotary root canal treatment in molars using the dental operating micr…
Immediate Implant Placement in Fresh Mandibular Molar Extraction Socket: 8-Year Results. A Case Report
2010
Abstract Recently, successful implant placement in fresh extraction sockets has been reported. In this case report, we present the results of an immediate implant placement in a fresh extraction socket of a mandibular molar with simultaneous bone regeneration using a nonresorbable membrane and no other graft materials. Clinical and radiographic findings acquired 8 years after implant placement demonstrated a stable peri-implant situation and confirmed a satisfactory treatment result.
Biangular fractures of the mandible
2013
Summary Introduction Bifocal fractures of the mandible often associate the angle and condyle or symphysis. Little data is available on biangular fractures. The authors had for aim to study their characteristics and to suggest an adapted management. Material and methods We retrospectively reviewed the records of patients operated on for a biangular fracture from January 2005 to December 2009. The impact of a third molar was evaluated using Pell and Gregory's and Shiller's classifications. Results Six hundred and forty patients underwent surgery for a mandibular fracture, seven of whom (1.1%) for biangular fractures. The patients’ mean age was 27.6 years. Patients were predominantly men (85.7…
Pathological mandibular fracture after simple molar extraction in a patient with osteogenesis imperfecta treated with alendronate
2009
Osteogenesis imperfecta (OI), is a heterogeneous group of inherited disorders of connective tissue characterized by bone fragility. Patients with this disease frequently suffer fractures, over 80% of the extremities due to the more intensive mechanical load. Fractures of the facial bones occur very infrequently. Several studies have proved that bisphosphonate therapy may be effective in reducing fracture risk in OI patients. We report here an unusual case of pathological mandibular fracture following simple molar extraction in an adult patient with OI type I and oral alendronic acid treatment. Extraction was atraumatical and without bone removal . Fracture was treated by internal fixation b…
FiberWire tension band for patellar fractures.
2015
Background Symptomatic hardware represents the most frequent complication reported following surgical treatment of patellar fracture. For this reason, some authors suggested using nonabsorbable sutures to fix the fracture with various techniques. The aim of this study was to evaluate clinical and radiological results of patients treated following a modified Pyriford technique using a FiberWire suture (Arthrex, Naples, FL, USA). Materials and methods We retrospectively evaluated a case series of seventeen patients with displaced patellar fractures treated by open reduction and internal fixation with a modified tension band using FiberWire sutures. Clinical and radiological outcome were eval…
Maxillofacial fracture epidemiology and treatment plans in the Northeast of Iran: A retrospective study
2017
Background: The epidemiology of facial injuries varies based on lifestyle, cultural background and socioeconomic status in different countries and geographic zones. This study evaluated the epidemiology of maxillofacial fractures and treatment plans in hospitalized patients in Northeast of Iran (2015-2016). Material and Methods: In this retrospective study, the medical records of 502 hospitalized patients were evaluated in the Department of Maxillofacial Surgery in Kamyab Hospital in Mashhad, Iran. The type and cause of fractures and treatment plans were recorded in a checklist. Data were analyzed with Mann–Whitney test, chi-squared test and Fisher’s exact test, using SPSS 21. Results: The …
