AbstractCerebrospinal fluid (CSF) pathway studies have revealed that the CSF secreted from the choroid plexus of the ventricles after egressing from the fourth ventricle reaches the basal suprasellar cistern and ultimately the sylvian cisterns. From the sylvian cistern, the CSF travels over the cerebral convexity subarachnoid space to reach the superior sagittal sinus and enters the bloodstream. Diverting CSF from the lateral ventricle with a shunt catheter to the sylvian cistern can be an option to treat obstructive hydrocephalus. An adult patient with posttraumatic hydrocephalus with contraindications to ventriculoperitoneal and ventriculoatrial shunt placement underwent this procedure of diverting CSF from the lateral ventricle to the sylvian cistern successfully, and he had immediate relief of symptoms of raised intracranial pressure. Although preliminary results seem logical and promising, more cases and longer follow-up is required to consider this shunt operation an option in the treatment of obstructive hydrocephalus.

Force Data

Knowledge of positional and force properties of surgical dissection in neurosurgery is essential in developing simulation platforms for neurosurgical training such that realistic motion and perception can be conveyed to the trainee during practice. Most proposed models in literature utilize computational techniques to formulate required parameters. However, these models are not realistic enough compared to data obtained from experiments on real brain. Therefore, developing a setup to measure the position, orientation, and interaction forces will help researchers formulate realistic parameters. This paper presents the development of such a setup for quantification of displacements and tool-tissue interaction forces during performance of microsurgical tasks. A bipolar forceps is equipped with a set of force sensing elements to measure the tool-tissue interaction force components. The position and orientation of the forceps tips are measured by attaching a tracker to the bipolar forceps. To show proof-of-concept, an experienced surgeon and one assistant surgeon performed 35 neurosurgical tasks (320 trials) on a cadaver brain (previously-frozen) using the instrumented setup. Positional and force data of the bipolar forceps were recorded during surgical dissection of different brain structures. This paper reports results collected from two microsurgical tasks over 40 trials: dissection of sylvian cistern arachnoid (SCA) and dissection of middle cerebral artery (MCA). Results showed that the mean values of interaction forces during dissection of MCA were smaller than dissecting SCA. The maximum forces observed were 1.94 N and 1.75 N for SCA and MCA, respectively. The application of quantifying such parameters using the developed setup will be in training neurosurgery residents using surgical simulators in which the knowledge of brain tissue parameters is required to formulate the tissue model.

Abstract OBJECTIVE: We introduce the lateral transsulcal approach to asymptomatic trigonal meningiomas. METHODS: The approach was studied in two cadaver brains and three asymptomatic patients with trigonal meningiomas. The posterior part of the sylvian fissure, or superior temporal sulcus, is opened to the bottom. Through a small horizontal cortical incision, the trigone of the lateral ventricle is exposed in the shortest distance. The trigonal meningiomas are detached from the choroid plexus and removed. RESULTS: In patients with meningiomas on the nondominant side, the transsylvian approach was adopted. In patients with meningiomas on the dominant side, the transsylvian approach was adopted for patients with a wide sylvian cistern, and the approach through the superior temporal sulcus was adopted for patients with a narrow sylvian cistern. The transverse gyrus of Heschl was a good anatomic landmark in the operative field of the transsylvian approach. Patients with meningiomas on the dominant side exhibited transient amnestic aphasia and dyscalculia, but the symptoms disappeared in a few days or weeks. These patients were discharged without any neurological deficits. Although there are potential risks of damaging association fibers, optic radiation, the transverse gyrus of Heschl, and the parietal lobe, a thorough understanding of the topographical anatomy and careful dissection techniques can avoid morbidity. Wide opening of the sylvian fissure and debulking of the tumor are other important factors to reduce the retraction of the parietal and temporal lobes. CONCLUSION: The lateral transsulcal approach is applicable for small asymptomatic trigonal meningiomas with an acceptable risk of morbidity, even in the dominant hemisphere.
