BACKGROUND: Occipital-cervical fusion (OCF) and ventral decompression (VD) may be used in the treatment of pediatric Chiari-1 malformation (CM-1) with syringomyelia (SM) as adjuncts to posterior fossa decompression (PFD) for complex craniovertebral junction pathology. OBJECTIVE: To examine factors influencing the use of OCF and OCF/VD in a multicenter cohort of pediatric CM-1 and SM subjects treated with PFD. METHODS: The Park-Reeves Syringomyelia Research Consortium registry was used to examine 637 subjects with cerebellar tonsillar ectopia ≥ 5 mm, syrinx diameter ≥ 3 mm, and at least 1 yr of follow-up after their index PFD. Comparisons were made between subjects who received PFD alone and those with PFD + OCF or PFD + OCF/VD. RESULTS: All 637 patients underwent PFD, 505 (79.2%) with and 132 (20.8%) without duraplasty. A total of 12 subjects went on to have OCF at some point in their management (PFD + OCF), whereas 4 had OCF and VD (PFD + OCF/VD). Of those with complete data, a history of platybasia (3/10, P = .011), Klippel-Feil (2/10, P = .015), and basilar invagination (3/12, P

Objective Rathke cleft cysts (RCCs) are cystic epithelial lesions in the sellar and suprasellar regions that are often discovered incidentally. They require surgical fenestration and drainage in a small proportion of patients who develop symptoms or demonstrate progressive enlargement. Our aim was to review our experience with pediatric patients treated surgically for RCCs. Methods A retrospective review was conducted of all patients treated surgically for RCCs at Childrens Hospital Los Angeles between 1999 and 2007 after approval by the institutional review board. Clinical notes, operative reports, radiological studies, and pathology reports were reviewed. The median follow-up period was 34 months. Results Ten patients undergoing surgical treatment of an RCC were identified, making up 20% of the 51 patients with RCCs followed clinically over the same time period. The mean age was 13 years (age range, 2-17 years). There were 6 females and 4 males. Patients requiring surgery presented with the following clinical symptoms: headache (8 patients, 80%), endocrine insufficiency (6 patients, 60%), meningitis followed by visual loss (1 patient, 10%), and incidental finding (1 patient, 10%). The mean cyst diameter was 13.6 mm (range, 8-18 mm). Four patients had strictly sellar lesions, 4 patients had suprasellar extension of an RCC, and 2 patients had primarily suprasellar RCCs. Nine of 10 patients underwent transsphenoidal surgery, and 1 patient underwent a pterional craniotomy. Complete cyst drainage on radiography was noted in 9 of 10 patients (90%), all of whom underwent transsphenoidal surgery. One patient experienced a symptomatic recurrence 6 years after complete surgical drainage. Headaches improved in 7 of 8 patients after surgery. Two patients had complete resolution of a hormonal axis deficit, whereas 3 patients developed new anterior pituitary axis deficits. Two patients developed persistent diabetes insipidus after surgery. Conclusion RCCs are an infrequent cause of symptoms in pediatric patients. The transsphenoidal approach offers an effective means of achieving complete cyst drainage for lesions requiring surgery. Fenestration and aspiration of the cyst are usually sufficient to achieve total resolution of symptoms and signs caused by RCCs. Clinical symptoms such as headaches improved in the majority of patients, whereas hormonal disturbances typically persisted. Patient selection remains of paramount importance when considering surgery for pediatric patients with RCCs.

INTRODUCTION:The first choice for distal end location of a cerebrospinal fluid-diverting device is the abdomen. However, for patients in whom the peritoneal cavity is not suitable, a ventriculopleural shunt (VPl) is an alternative.METHODS:With institutional review board approval we performed a retro

Patients with nonsyndromic sagittal craniosynostosis (SC) were previously thought to have normal neurocognitive development; however, a pattern of mild delays has been described in these patients. We reviewed our patients with SC to identify potential perinatal risk factors that serve as indicators for subsequent developmental delay.Nonsyndromic patients with SC (n = 66) completed preoperative Bayley Scales of Infant and Toddler Development (III) with a single examiner between August 2009 and April 2015. Patients were classified as having no delays (n = 52; 79%) or having delays (n = 14; 21%) below the ninth percentile in one or more area(s) of development. Mean differences were compared using Multivariate Analyses of Variance.Participants were mostly male (79%) and aged 2 to 12 months at testing. There were no group differences in sociodemographic categories. Prenatally, patients in the group with delays vs the group with no delays had lower gestational age in weeks (36.9 vs 39.2, P
