Redo Posterior Fossa Decompression with Duraplasty for the Treatment of Chiari Type I Malformation
Chiari decompression is a common neurosurgical procedure. Chiari malformations present with a number of symptoms including Valsalva-induced headaches, swallowing dysfunction, and sleep apnea. Chiari malformations can also cause syringomyelia and syringobulbia. Surgical procedures used for the treatment of Chiari malformation include bone-only decompression (posterior fossa craniectomy +/- cervical laminectomy), craniectomy/laminectomy with duraplasty, and craniectomy/laminectomy/duraplasty with shrinkage or resection of the cerebellar tonsils. The procedure used depends on the specifics of the patient’s condition and the preference of the surgeon.
The patient presented here had undergone a prior Chiari decompression at the age of 20 months. This was bone-only with posterior fossa craniectomy and C1-2 laminectomy. The dura was not opened due to the presence of a venous lake. He initially had improvement in his symptoms. However, his headaches and snoring recurred, balance worsened, and dysphagia never improved. Therefore, a repeat Chiari decompression at the age of 28 months was performed as presented here.
Excision of Macrocystic Lymphatic Malformation
Lymphatic malformations (LM) are composed of dilated, abnormal lymphatic vessels classified as macrocystic (single or multiple cysts >2 cm3), microcystic (<2 cm3), or mixed. This patient is a 5-month-old with a right neck mass consistent with macrocystic lymphatic malformation on MRI. This low-flow vascular malformation required surgical intervention. Methods The site was marked in a natural skin crease. Subplatysmal flaps were raised and malformation was immediately encountered. Blunt soft tissue dissection was performed immediately adjacent to the mass to reflect tissue off the fluid-filled lesion. Neurovascular structures were preserved in this process. Mass was removed in total and Penrose drain and neck dressing were placed. Results A complete resection was performed. LM was confirmed on pathology. Patient is doing well with no deficits noted. The drain was removed after 1 week. One-month follow-up showed no recurrence. Conclusion Macrocystic lymphatic malformations are amenable to surgical resection at low risk and without recurrence.
