Left-handedness should not be overrated as a risk factor for postoperative speech impairment in children after posterior fossa tumour surgery: a prospective European multicentre study.

Purpose: Cerebellar mutism syndrome (CMS) is a severe neurological complication of posterior fossa tumour surgery in children, and postoperative speech impairment (POSI) is the main component. Left-handedness was previously suggested as a strong risk factor for POSI. The aim of this study was to investigate the relationship between handedness and the risk of POSI.

Postoperative speech impairment and surgical approach to posterior fossa tumours in children: a prospective European multicentre cohort study.

Background: Brain tumours are the most common solid tumours in childhood. Half of these tumours occur in the posterior fossa, where surgical removal is complicated by the risk of cerebellar mutism syndrome, of which postoperative speech impairment (POSI) is a cardinal symptom, in up to 25% of patients. The surgical approach to midline tumours, mostly undertaken by transvermian or telovelar routes, has been proposed to influence the risk of POSI.

Living with the cerebellar mutism syndrome: long-term challenges of the diagnosis.

Background: After posterior fossa tumour surgery, up to 39% of children experience postoperative cerebellar mutism syndrome (CMS) characterized by mutism and other motor and cognitive impairments. There is a lack of knowledge on the patient-reported challenges and long-term needs. Consequently, no specific recommendations exist for rehabilitative and supportive interventions for patients with CMS.

The supplementary motor area syndrome and the cerebellar mutism syndrome: a pathoanatomical relationship?

Purpose: The supplementary motor area (SMA) syndrome affects adults after tumour resection in SMA neighbouring motor cortex. Cerebellar mutism syndrome (CMS) affects children after tumour resection in the posterior fossa. Both syndromes include disturbances in speech and motor function.

Cerebellar Mutism Syndrome and Other Complications After Surgery in the Posterior Fossa in Adults: A Prospective Study.

Background: Cerebellar mutism syndrome (CMS) is rarely described in adults; however, data on self-assessed linguistic complications after posterior fossa surgery do not exist.

Methods: Through a prospective single-center study, data on 59 tumor operations in the posterior fossa were collected preoperatively as well as 1 week and 1 month postoperatively. Data on self-assessed problems in 5 CMS-related domains, CMS scores, and neurology as well as surgical procedure and complications were obtained.

Cerebellar mutism syndrome in children with brain tumours of the posterior fossa.

Background: Central nervous system tumours constitute 25% of all childhood cancers; more than half are located in the posterior fossa and surgery is usually part of therapy. One of the most disabling late effects of posterior fossa tumour surgery is the cerebellar mutism syndrome (CMS) which has been reported in up to 39% of the patients but the exact incidence is uncertain since milder cases may be unrecognized. Recovery is usually incomplete.

Osmolality of Cerebrospinal Fluid from Patients with Idiopathic Intracranial Hypertension (IIH).

Introduction: Idiopathic intracranial hypertension (IIH) is a disorder of increased intracranial fluid pressure (ICP) of unknown etiology. This study aims to investigate osmolality of cerebrospinal fluid (CSF) from patients with IIH.

Methods: We prospectively collected CSF from individuals referred on suspicion of IIH from 2011-2013.
