Comparative Study
Predicting potential of rapid tumor growth in small to medium vestibular schwannomas on the basis of sway assessed using posturography.
The relationship between quantitative posturography results and growth of vestibular schwannomas (VSs) during conservative management has not been studied. We aimed to clarify the relationship between the presence of disequilibrium based on posturographic measurement and VS growth. ⋯ We demonstrated a positive correlation between SV with eyes open and future tumor growth. Posturographic data are objective and quantitative; thus, SV may be a potential predictor of future growth of VSs.

The purpose of this study was to compare clinical results of microendoscopic laminectomy (MEL) with those of unilateral biportal endoscopic laminectomy (UBEL) in patients with single-level lumbar spinal canal stenosis. ⋯ The UBEL method is a more useful technique than the MEL method as it requires a smaller bone resection area and produces fewer complications.

Intrasellar cephalocele is very rare and is often overlooked because of its atypical clinical demonstration. A 2-year, 10-month-old girl was referred to our hospital with short stature. Magnetic resonance imaging revealed an extension of the anterior third ventricle, which protruded into the pituitary fossa, but not into the craniopharyngeal canal, sphenoid bone, or sphenoid sinus. ⋯ Thus the patient was clinically diagnosed with intrasellar cephalocele, which is considered as a rare subtype of transsphenoidal cephalocele. Instead of surgical intervention, the patient was given growth hormone replacement therapy. After 1-year follow-up, the patient had significant increase in height.

For patients with multilevel degenerative cervical myelopathy, laminectomy and fusion are widely accepted techniques for ameliorating the disorder. However, the idea of whether one should bridge the cervicothoracic junction to prevent instrument failure or adjacent segment disease has been a subject of controversial discussion. In the present study, we compared the incidence of these complications and the revision rates in multilevel fusions extending to C7 or T1-T3. ⋯ We found that fewer revisions were necessary if the fusion had extended to the thoracic spine. Thus, we recommend bridging the cervicothoracic junction when fusion starts at C0-C3.

A paucity of literature is available discussing the associated risk factors, treatment options (including the use of minimally invasive surgery), and outcomes related to lumbar disc herniation (LDH) in children. We have discussed the risk factors for disc disease among pediatric patients and evaluated the efficacy of the minimally invasive approach. ⋯ Risk factors similar to those for adult LDH, such as an elevated body mass index, can be seen in the pediatric population. However, some unique risk factors such as post-traumatic LDH were found in the pediatric age group. Minimally invasive techniques are demonstrably safe and useful in this patient population.
