At present, presurgical functional mapping is the most prevalent clinical application of functional magnetic resonance imaging (fMRI). Signal dropouts and distortions caused by susceptibility effects in the current standard echo planar imaging (EPI)-based fMRI images are well-known problems and pose a major hurdle for the application of fMRI in several brain regions, many of which are related to language mapping in presurgical planning. Such artifacts are particularly problematic in patients with previous surgical resection cavities, craniotomy hardware, hemorrhage, and vascular malformation...

Neoadjuvant Targeted Molecular Therapy in the setting of localized and locally advanced renal cell carcinoma has emerged as a strategy to render primary renal tumors amenable to planned surgical resection in settings where radical resection or nephron-sparing surgery was not thought to be safe or feasible. Presurgical tumor reduction has been demonstrated in a number of studies including a recently published randomized double-blind placebo-controlled study, and an expanding body of literature suggests benefit in select patients...

Hyun Ho Han, Daiwon Jun, Goo Hyun Mun, Suk-Ho Moon
In spite of thorough presurgical planning, emergency situations requiring longer pedicle length may arise during anterolateral thigh (ALT) free flap surgeries. While performing vessel graft for pedicle lengthening, discrepancy may occur because of a certain genetic predisposition or vascular variation at the anastomosis site of the graft vessel and the flap pedicle. A 76-year-old male patient with neurofibromatosis type I had a 15 x 10 cm defect, which was caused by radical excision of a malignant peripheral nerve sheath tumor on his back...

A 49-year-old patient reported for immediate replacement of missing maxillary anterior teeth with implant-retained prosthesis. Elevation of flap alters the mucosal level, causes discomfort, and delays the restorative procedure. To maintain the esthetics, flapless surgery was planned. Since placement of an implant is pre-planned in a predetermined site, fabrication of the prostheses before commencement of the surgery, especially when replacing the teeth in the anterior region, could be a viable option. This case report explains the method of fabrication of the provisional restoration for flapless surgery in the presurgical phase...

BACKGROUND: Computer-guided 3D virtual planning and customized templates are novel and effective methods aiding maxillary reconstruction, particularly during osteocutaneous free tissue transfer of complex defects. However, virtual planning and modelling is often expensive. METHODS: We present a new method to reconstruct complex defects with a surgical stent designed from presurgical casts. We present 2 patients who underwent this technique. Reconstruction in both cases was aided by a surgical stent fashioned preoperatively to approximate the anatomic dimensions of the defect, guiding the shape and orientation of the flap during inset to aid in dental rehabilitation...

Endometriosis is a common gynecological disorder defined by the presence of endometrial tissue outside the uterus. It is the most common cause of chronic pelvic pain and typically affects the ovaries, uterine ligaments, peritoneum, tubes, rectovaginal septum and bladder. It may, however, be found at various extrapelvic sites, including the perineum, liver, pancreas, lung or even the central nervous system, and in such cases, diagnosis may be quite challenging. Even though definitive diagnosis requires laparoscopy, preoperative identification of endometriosis is important not only to differentiate it from other diseases with similar clinical presentations but also, for accurate presurgical mapping, since complete removal of all endometriotic foci is critical for the effective treatment of the patient's symptoms...

In the surgical management of epilepsy, the resection of cortex exhibiting interictal fast ripples (250-500Hz) on electrocorticography has been linked to postoperative seizure-freedom. Although fast ripples appear to accurately identify the epileptogenic zone-the minimum tissue that must be removed at surgery to achieve seizure-freedom-it has not been established that fast ripples are a superior biomarker in comparison with multimodal presurgical neuroimaging and other electrocorticography abnormalities. Hence, in the prediction of postoperative seizure-freedom, we compared the value of fast ripples with other intraoperative electocorticography abnormalities including focal slowing, paroxysmal fast activity, intermittent spike discharges, continuous epileptiform discharges, focal attenuation, and intraoperative seizures, as well as complete resection of the lesion defined by MRI and other neuroimaging...

INTRODUCTION: Mandibular incisor axis correction can be challenging in non-extraction orthodontic treatment planning. Mandibular anterior segmental subapical osteotomy (MASSO) is a surgical approach, which can be used to reposition incisor axis, improve occlusal function and enhance the soft tissue profile. METHODS: Twenty-eight patients, mean age 22.6 years (16-39, SD=6.69), were treated for MASSO for correction of Class II dentoskeletal deformity, in addition to other orthognathic procedures...
