Large mediastinal masses are rare, and encompass a wide variety of diseases. Regardless of the diagnosis, all large mediastinal masses may cause compression or invasion of vital structures, resulting in respiratory insufficiency or hemodynamic decompensation. Detailed preoperative preparation is a prerequisite for favorable surgical outcomes and should include preoperative multimodality imaging...

This article provides a concise description of common complications of rhinoplasty, recommendations for avoidance, and corrective techniques. The surgeon must have a comprehensive understanding of nasal anatomy and effects of surgical maneuvers to help avoid complications. Meticulous history, physical examination, and standardized photographic documentation are central to preoperative evaluatio...

This article summarizes the key features and clinical considerations related to preoperative management and planning for the care of patients of common endocrine disorders (diabetes mellitus, adrenal insufficiency, thyroid disease), a less common disorder but one that has significant perioperative implications (acromegaly), and 2 disorders for which preoperative management is essential to good ...

In pediatric living-related liver transplantation, preoperative evaluation of the recipient is important for surgical planning, while the accurate diagnosis of postoperative complications is essential for graft salvage. Multiplanar and three-dimensional imaging using multi-slice spiral CT can be used for preoperative vascular imaging, as well as for evaluating postoperative complications. In th...

BACKGROUND/AIM To investigate the effect of positron emission tomography-computed tomography (PET/CT)-based contouring on dosimetric parameters in rectal cancer patients undergoing preoperative intensity-modulated radiation therapy (IMRT). MATERIALS AND METHODS Preoperative radiation therapy plans with conformal radiotherapy (CRT) or IMRT were created and examined according to the CT- and PET...

A 14-year-old boy presented with symptomatic high-grade dysplastic type spondylolisthesis, with a presence of spina bifida occulta, not diagnosed by plain radiographs, but confirmed on preoperative CT and MR. Circumferential fusion with partial reduction of L5/S1 was performed. Awareness of the coexistence of spondylolisthesis and spina bifida by an accurate preoperative planning is paramount t...

For genu recurvatum deformity after tibial fracture, precise correction osteotomy is necessary to acquire a good clinical outcome. No report on genu recurvatum has evaluated precise preoperative planning with image-processing software for three-dimensional (3D) design and modeling. We herein report a case of osseous genu recurvatum treated by anterior opening wedge osteotomy according to precis...

Towards the last years we can observe a strong trend towards preoperative planning and integration of rapid prototyp-ing methods into computer assisted surgery workflows. In this lecture we summarize the current state of development in the field of interactive teleplanning and present recent clinical results of navigation guided insertion of individualized 3D facial implants, manufactured accor...

BACKGROUND To study the diagnostic accuracy of physical examination (PE), ultrasonography (US), contrastenhanced computed tomography (CT) and in preoperative detection of macroscopic nodal metastasis in primary/recurrent papillary thyroid carcinoma (PTC) patients to determine if the routine addition of CT would be beneficial in accurate preoperative lymph-node surgery planning. METHODS In a t...

the aim of this study was to evaluate the morbidity and mortality in patients with operable stage ii and iii rectal cancers within one or two months after surgery, who has been treated pre-operatively with short course radiotherapy. twenty-eight patients with rectal adenocarcinoma, consecutively referred to the cancer institute of imam khomeini hospital from march 2009 to march 2010, were selec...
