INTRODUCTION Computer-assisted preoperative simulation surgery is employed to plan and interact with the 3D images during the orthognathic procedure. It is useful for positioning and fixation of maxilla by a plate. We report a case of maxillary retrusion by a bilateral cleft lip and palate, in which a 2-stage orthognathic procedure (maxillary advancement by distraction technique and mandibular ...

Preoperative planning combined with image-guidance has shown promise towards increasing the accuracy of liver resection procedures. The purpose of this study was to validate one such preoperative planning tool for four patients undergoing hepatic resection. Preoperative computed tomography (CT) images acquired before surgery were used to identify tumor margins and to plan the surgical approach ...

INTRODUCTION Accurate and confident treatment planning is an essential part of endodontic practice. Periapical radiographs have been used to aid in the diagnosis of pathology and to help establish an appropriate treatment strategy. Recently, a new imaging modality, cone-beam volumetric tomographic (CBVT) imaging, has been shown to be a useful tool in a number of endodontic applications. The aim...

  The present review classifies and describes the multifactorial causes of anterior cruciate ligament (ACL) surgery failure, concentrating on preventing and resolving such situations. The article particularly focuses on those causes that require ACL revision due to recurrent instability, without neglecting those that affect function or produce persistent pain. Although primary ACL reconstructio...

BACKGROUND AND PURPOSE The role of diffusion tensor imaging (DTI) in neurosurgical planning and follow-up is currently being defined and needs clinical validation. To that end, we sought correlations between preoperative and postoperative DTI and clinical motor deficits in patients with space-occupying lesions involving the corticospinal tract (CST). METHODS DTI findings in four patients with...

conclusions the findings of this survey showed that shortening the duration of pre-adenotonsillectomy fasting period and hydration of patients several hours prior to the operation might be effective in decreasing postoperative pain and facilitating postoperative oral feeding initiation. nevertheless this method does not seem to prevent postoperative nausea and vomiting. results the amount of ac...

background: the routine use of preoperative appropriate paraclinic testing is useful in patients scheduled to undergo elective surgery. the purpose of this study was to assess the prevalence of unnecessary preoperative evaluation performed for patients undergoing elective surgeries.methods: this descriptive analytic study was performed to assess the patterns of preoperative evaluation tests on ...

BACKGROUND Computed tomographies (CTs) and magnetic resonance imagings (MRIs) have been traditionally used to evaluate cochlear implant (CI) candidates. The utility of preoperative imaging in pediatric CI candidates is well documented because anatomic abnormalities can alter surgical planning in up to 20% of cases. However, the utility of preoperative imaging is yet to be determined in adult CI...
