Abstract :
Background: In this study we have evaluated the clinical presentations, diagnosis, intraoperative findings and clinical outcome in patients with Chiari I malformations undergoing posterior cranial fossa decompression Materials and Methods: Outcome was assessed by Thirty patients with different age groups with Chiari I malformations who underwent suboccipital craniectomy and wide duroplasty .The clinical evaluation of postoperative signs and symptoms and magnetic resonance imaging of the cranioverteal junction were analyzed. Results: Headache in 24(80%) patients and neck pain in18 (54%) were the most common symptoms. Syringomyelia was present in 21 patients (21%).scoliosis in 4 patients (12%), basilar invagination in 2 patients (6%). Female predominance of the malformation was observed, with a female: male ratio of 3:2.The mean age of onset was 27 years and 7 months. No reported positive family history. All patients had descent of cerebellar tonsils. The cerebellar tonsils were found to lie at C1 and C2 in 24 and 6 patients respectively. All patients underwent suboccipital decompresssion and autologous duroplasty using fascia lata in 18 patients and G patch (prolene) in 12 patients. The immediate postoperative period,24(91 %) of patients showed improved symptomatology and post operative magnetic resonance imaging revealed favourable findings comprising syrinx collapse or reduction of syrinx diameter in 85 % of patients. The mean follow–up period was 3 years and 4months. There was no mortality associated with the procedure. Cereospinal fluid leak (CSF) and meningitis was present in 7(21%) cases using G patch for duroplasty and 2 cases(6%) using fascia lata for duroplasty. Conclusions: The ACM type I can vary in presentation throughout in different age groups, Suboccipital decompression and duroplasty in selected cases are effective treatment for most patients with Chiari I malformations.
