introduction: first branchial cleft anomalies manifest with duplication of the external auditory canal.   case report: this report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. external auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...

Degeneration of the intervertebral disc results in initial relative instability, hypermobility, and hypertrophy of the facet joints, particularly at the superior articular process. This finally leads to a reduction of the spinal canal dimensions and compression of the neural elements, which can result in neurogenic intermittent claudication caused by venous congestion and arterial hypertension ...

STUDY DESIGN Retrospective cross-sectional study. OBJECTIVE This study aimed to elucidate the relationship among facet orientation, kinematics of a spinal unit, and change in lumbar spine canal diameter by using kinetic magnetic resonance imaging. SUMMARY OF BACKGROUND DATA Some studies have suggested an association between increased sagittally oriented facet angles and degenerative lumbar ...

BACKGROUND Senile systemic amyloidosis (SSA) derived from wild-type transthyretin is a fairly common condition of old individuals, particularly men. The main presentation is by cardiac involvement, which can lead to severe restrictive cardiomyopathy. SSA is, however, a systemic disease, and amyloid deposits may appear in many other tissues but are thought to be without clinical symptoms outside...

PURPOSE Percutaneous epidural neuroplasty (PEN) is a minimally invasive treatment. The efficacy of PEN has been relatively well investigated; however, the relationship between the clinical effectiveness of PEN and the severity of spinal canal stenosis by disc material has not yet been established. The purpose of this study was to compare clinical outcomes of PEN according to the dural sac cross...

The aim of this retrospective study was to compare the short-term (4 weeks) surgical complications after unilateral laminotomy for bilateral decompression (ULBD) in patients with lumbar spinal stenosis, below and above age 65. Twenty-nine consecutive patients operated upon in 2011 were included: 12 below age 65, and 17 above age 65. Five complications (17.1%) were observed, all in the older age...

A variety of implant-related short and long-term complications after lumbar fusion surgery are recognized. Mid to long-term complications due to cage migration and/or cage subsidence are less frequently reported. Here, we report a patient with a complete cage migration into the superior adjacent vertebral body almost 20 years after the initial posterior lumbar interbody fusion procedure. In thi...

1. Ciol – J Am Geriatr Soc 1996 OVERVIEW Lumbar spinal stenosis (LSS) is the most common reason for spine surgery in people over the age of 65 in the United States.1 This program will cover the clinical issues around LSS: clinical presentation, diagnosis, and treatments. The various treatment options for the symptoms of LSS that will be presented include: non-operative care, surgical interventi...
