Arnold Chiari Malformation Surgery. The most common surgery to treat chiari malformation is posterior fossa decompression. Spinal laminectomy is another type of surgery to correct the malformation.
Spinal laminectomy is another type of surgery to correct the malformation. You will lie on the operating table and be given anesthesia. The surgery involves making an incision at the back of the head and removing a small portion of the bone at the bottom of the skull craniectomy.
Surgery for chiari in adults is common and carries a definitive risk profile including rates of readmission and reoperation higher than other common neurosurgical procedures.
A part of the spine is also removed at times. Chiari decompression surgery removes bone at the back of the skull to widen the foramen magnum and create space for the brain. In this chiari malformation surgery an incision is made at the head s rear. It creates more space for the cerebellum and relieves pressure on the spinal cord.
