BACKGROUND: Crooked nose deformity is one of the most difficult issues to correct by rhinoplasty, as it can result in undesired late sequelae. Revision rates are often high, and numerous operational techniques have been tested. This study describes a crooked nose rhinoplasty technique that reduces the need for a double osteotomy in the long nasal bone. METHODS: This study included 26 patients with an I-shaped crooked nose deformity. In the surgical correction of the crooked nose deformity, previously defined techniques were applied to the cartilage identically...

REVIEW
I David Kaye, Alan S Hilibrand
PURPOSE OF REVIEW: The precise etiology of adjacent segment disease following cervical spine surgery is controversial. Theories for development include inevitable changes secondary to the natural progression of the degenerative cascade and changes secondary to altered biomechanics of the fused cervical spine. Motion preserving techniques, such as cervical disc arthroplasties (CDA), have been introduced with the hopes of reducing the rates of adjacent segment pathology. Recently, 7-year data from the investigational device exemption (IDE) studies have been published...

While abnormal loading is widely believed to cause cervical spine disc diseases, in-vivo cervical disc deformation during dynamic neck motion has not been well delineated. This study investigated the range of cervical disc deformation during an in-vivo functional flexion-extension of the neck. Ten asymptomatic human subjects were tested using a combined dual fluoroscopic imaging system and MRI based 3D modeling technique. Overall disc deformation was determined using the changes of the space geometry between upper and lower endplates of each intervertebral segment (C3/4, C4/5, C5/6 and C6/7)...

BACKGROUND: Traumatic C2-3 dislocation has been often described in the antero-posterior plane but is extremely rare in the lateral plane. Such dislocations have been described in thoraco-lumbar and C1-2. The need to study the imaging in multiple planes has been highlighted to plan proper realignment. METHODS: A young male presented with neck pain alone following a train accident. The imaging showed a fracture of C3 splaying it. The C2-3 showed lateral dislocation in the lateral plane with locked C2-3 facets on one side and C3-4 facets on the other...

STUDY DESIGN: Retrospective analysis of 16 patients. SUMMARY OF BACKGROUND DATA: The lumbar split fracture-dislocation is a rare but severe injury, which is type C1.2.1 fracture in the Association for the Study of Internal Fixation spine fracture classification. The axial compressive and torsional force shattered the vertebral body into 2 halves and displaced them rotationally. This kind of fracture is so highly unstable that the treatment is very challenging. PURPOSE: The purpose of this study was to report and compare on clinical outcome and complications of patients with lumbar split fracture-dislocation which had been treated either short-segment or long-segment posterior fixation and anterior fusion...

Objectives/Hypotheses Functioning pituitary adenomas may produce endocrinopathies such as acromegaly and Cushing syndrome. Both conditions lead to characteristic anatomic variations as a result of hormonally induced abnormal soft tissue deposition. We evaluate the anatomic differences between acromegalics and Cushing disease patients and compare these dimensions to controls. Design Radiographic review of preoperative magnetic resonance images (MRI) of the pituitary gland. Setting Tertiary academic medical center...

STUDY DESIGN: A retrospective study. PURPOSE: To explore the risk factors for reintubation after airway obstruction following anterior cervical surgery. STUDY BACKGROUND: Anterior cervical surgery is an effective surgical therapy for cervical spine disorders. As the anterior approach is adopted more frequently, some rare postoperative complications come under the spotlight, among which, airway obstruction is extremely detrimental. However, the risk factors and the pathogenesis of the airway obstruction still remain unknown...

OBJECTIVE Cervical disc arthroplasty (CDA) has been demonstrated to be as safe and effective as anterior cervical discectomy and fusion (ACDF) in the management of 1- and 2-level degenerative disc disease (DDD). However, there has been a lack of data to address the fundamental discrepancy between the two surgeries (CDA vs ACDF), and preservation versus elimination of motion, in the management of cervical myelopathy associated with congenital cervical stenosis (CCS). Although younger patients tend to benefit more from motion preservation, it is uncertain if CCS caused by multilevel DDD can be treated safely with CDA...

OBJECTIVE Improvements in imaging technology have steadily advanced surgical approaches. Within the field of spine surgery, assistance from the O-arm Multidimensional Surgical Imaging System has been established to yield superior accuracy of pedicle screw insertion compared with freehand and fluoroscopic approaches. Despite this evidence, no studies have investigated the clinical relevance associated with increased accuracy. Accordingly, the objective of this study was to investigate the clinical outcomes following thoracolumbar spinal fusion associated with O-arm-assisted navigation...

Lower extremity avulsion fractures are uncommon in the pediatric population and can be misdiagnosed without proper imaging and/or clinical suspicion for these injuries. The most common locations of avulsion injuries are the ischial tuberosity, anterior superior iliac spine, and anterior inferior iliac spine. Less often, avulsion fractures occur in the tibial tubercle, calcaneus, and greater and lesser trochanters. When treated properly with rest and altered weight bearing, most of these injuries heal without complication...

INTRODUCTION: The restoration of normal jaw function, optimal facial aesthetics and long term stability are the goals of any orthognathic surgical procedures. During the last two decades, several cephalometric investigations have been reported on the skeletal changes following maxillary surgical procedures. The stability following LeFort I osteotomy and maxillary superior repositioning of the maxilla has not been studied extensively. AIM: This study was aimed at determining the surgical changes brought about by superior repositioning of the maxilla by Le Fort I osteotomy and evaluate the stability of the surgical procedure one year following surgery...

Postoperative pain after bariatric surgery can be significant and yet difficult to manage. These patients frequently have associated obstructive sleep apnea and are at risk of respiratory depression with opioid analgesia. Abdominal wall blocks such as the subcostal transversus abdominis plane block are not of significant benefit, probably in part because they provide only somatic analgesia. The ultrasound-guided erector spinae plane (ESP) block is a recently described regional anesthetic technique for providing thoracic analgesia when performed at the level of the T5 transverse process...
