An abnormal maxillomandibular ridge relationship frequently hinders oral implant treatment in patients with jaw deformities. Here, we describe a patient who was experiencing difficulty using dentures due to multiple maxillary tooth loss and mandibular prognathism. Treatment comprising sagittal splitting ramus osteotomy and alveolar ridge augmentation using bone grafts harvested from the mandibular ramus followed by implant treatment yielded good outcomes. The patient was a 47-year-old woman presenting with an unstable upper partial denture...

Image matching is an outstanding issue because of the existing of geometric and radiometric distortion in stereo remote sensing images. Weighted α-shape (WαSH) local invariant features are tolerant to image rotation, scale change, affine deformation, illumination change, and blurring. However, since the number of WαSH features is small, it is difficult to get enough matches to estimate the satisfactory homography matrix or fundamental matrix. In addition, the WαSH detector is extremely sensitive to image noise because it is built on sampled edges...

INTRODUCTION: We describe our experience performing bladder augmentation revision without additional bowel harvest for certain suboptimal cystoplasty configurations. METHODS: We identified patients with prior bladder augmentation who underwent augmentation revision without additional bowel harvest at our institution. These patients were identified to have either "hourglass" deformity or non-detubularized augment previously. Revision was performed using an open technique by detaching the prior augment and performing detubularization and/or completion cystotomy as needed...

As data acquisition for retinal imaging with optical coherence tomography (OCT) becomes faster, efficient collection of photons becomes more important to maintain image quality. One approach is to use a larger aperture at the eye's pupil to collect more photons that have been reflected from the retina. A 2.8-mm beam diameter system with only 7 reflecting surfaces was developed for low-loss retinal imaging. The larger beam size requires defocus and astigmatism correction, which was done in a closed loop adaptive optics method using a Shack-Hartmann wavefront sensor and a deformable mirror with 140 actuators and a +/-2...

Transverse clefts of the oral cavity have significant impacts on both appearance and function. Many methods of repair have been described, but there is no consensus on optimal approach. In addition, dissatisfaction with scars, distortion of appearance, and recurrent deformity have led to complex surgical designs that are difficult to understand and reproduce. We describe a simple approach to repair that is based upon anatomic approximation of lip components and accurate repair of the muscle. Twenty patients underwent repair by the senior author, who devised the approach, and the corresponding author, who adopted it...

Cervical kyphosis is a rare condition that can cause significant functional disability and myelopathy. Deciding the appropriate treatment for such deformities is challenging for the surgeon. Patients often present with axial neck pain, and it is not uncommon to find coexisting radiculopathy or myelopathy. The optimal approach for addressing this complex issue remains controversial. A comprehensive surgical plan based on knowledge of the pathology and biomechanics is important for kyphosis correction. Here we reviewed diagnoses of the cervical spine along with the literature pertaining to various approaches and management of cervical spine...

Severe chest wall deformities are considered a contraindication for lung transplantation. A 38-year-old male with idiopathic pulmonary fibrosis and severe pectus excavatum with a Haller-Index of 4.3 was considered eligible and listed for lung transplantation. Bilateral sequential transplantation and simultaneous correction of the pectus excavatum was performed via anterolateral thoracotomies and Nuss-bar insertion with peripheral femoro-femoral veno-arterial ECMO support. TLC increased from 4.1l preoperative to 5...

Background: Increased implant number is thought to provide better control on the scoliotic spine, but there is limited scientific evidence of improved deformity correction and surgical outcomes with high-density constructs. The objective is to assess key anchor points used by experienced spinal deformity surgeons and to evaluate the effect of implant density pattern on correction techniques. Methods: Seventeen experienced spine surgeons reviewed five Lenke 1 adolescent idiopathic scoliosis cases and provided their preferred posterior correction technique (implant pattern, correction maneuvers, and implants used for their execution) and an alternative technique with the minimal implant density they felt would be acceptable (170 surgical plans total)...

The nonsurgical treatment of valley-type tear trough (TT) deformity with diffuse depression in preseptal segment aims a more effective and safer treatment alternative to present padding techniques through the use of hyaluronic acid fillers to the preseptal space. 22G 50-mm cannula was inserted into the preseptal space, 2 cm inferolateral to the lateral canthus, and a low concentration of monophasic hyaluronic acid filler was applied. TT deformity was treated through the elimination of the contrasting subcutaneous fat tissue quality and quantity both above and below the TT, which contributes to the accentuation of the TT deformity...

In 2009, the American Society of Plastic Surgeons Task Force on Autologous Fat Grafting (AFG) determined that autologous fat grafting was a safe procedure with a relatively low rate of complications. This consensus opinion unleashed a wave of popularity as plastic surgeons discovered the procedures' efficacy in a wide variety of cosmetic and reconstructive indications. Frequently reported cosmetic applications include soft-tissue augmentation of breast, buttocks, hips, face, and hands, whereas reconstructive applications include adjunct for breast reconstruction contour problems, plantar fat pad improvement, and correction of various posttraumatic and surgical contour deformities...
