ABSTRACT
BACKGROUND: This study compares dural hitching to surgicel and tisseel overlay graft following craniocervical decompression and C1 laminectomy with simple durotomy for Chiari I malformation. Outcome measures were syrinx decompression, headache resolution and complication rates. METHODS: A retrospective analysis of case notes was conducted. Patients who had undergone craniocervical decompression (CCD) were grouped by method of dural closure. Outcomes compared were rates of syrinx decompression, headache resolution, and post-operative complications. Statistical analysis was conducted using SPSS v20. RESULTS: We identified 32 adult patients for inclusion in this study. 53.1% (n = 17) had asyrinx, and 78.1% (n = 25) had a pre-operative headache. All were treated with suboccipital craniectomy, C1 laminectomy (with or without C2 laminectomy), and durotomy. The dura was either left open by dural hitching (n = 23) or closed with surgicel and tisseel overlay graft (n = 9). We found a statistically significant association between the method of dural closure and the rate of syrinx resolution. Resolution occurred in 91.7% (n = 11) of the hitching group, compared to 20.0% (n = 1) of the overlay graft group: Χ2(1) = 5.6, p = .018. There were no statistically significant differences between the two groups in the rates of headache resolution or other complications. CONCLUSIONS: In patients with symptomatic Chiari I malformation and associated syringomyelia, syrinx resolution is more likely if the dura is hitched open rather than closed bysurgicel and tisseel overlay graft after durotomy.

The aim of this study was to determine predictors of functional outcome and survival in a retrospective cohort of spinal cord ependymomas treated at a single institution. Twenty-six patients who underwent treatment of spinal cord ependymoma at a single institution were retrospectively analysed. The clinicopathological features were reviewed and correlated with functional outcome (measured using the Frankel grade), recurrence (clinical or radiological), progression-free survival (PFS) and overall survival (OS). Seventy-nine percent of patients with complete excision had maintained or improved functional outcome, compared to 75% in the incomplete resection plus radiotherapy group. Patients with a good pre-operative Frankel grade tended to maintain their functional status, though this did not reach statistical significance (Fisher's Exact test, P = 0.090). Univariate analysis revealed that longer symptom duration prior to treatment was associated with poorer functional outcome (P = 0.006). Extent of resection and the use of adjuvant radiotherapy did not influence PFS or OS; however, early diagnosis and treatment are paramount in the management of spinal ependymoma if a good functional outcome is to be achieved.

This 80-year-old woman presented with acute breathing difficulty during neck flexion when cyanosis also developed. The only potential causes were detected on cervical magnetic resonance imaging: two large anterior cervical osteophytes compressing the retropharyngeal space. Excision of these osteophytes resulted in resolution of the symptoms.
