Pre- and Post-Surgical Dysphagia in Adults with Tumors of the Posterior Fossa: A Prospective Blinded Study.

Background: While swallowing disorders are frequent sequela following posterior fossa tumor (PFT) surgery in children, data on dysphagia frequency, severity, and outcome in adults are lacking. The aim of this study was to investigate dysphagia before and after surgical removal of PFT. Additionally, we tried to identify clinical predictors for postsurgical swallowing disorders.

Effect of thalamic deep brain stimulation on swallowing in patients with essential tremor.

Objective: Deep brain stimulation (DBS) of the ventral intermediate nucleus (VIM) is a mainstay treatment for severe and drug-refractory essential tremor (ET). Although stimulation-induced dysarthria has been extensively described, possible impairment of swallowing has not been systematically investigated yet.

Methods: Twelve patients with ET and bilateral VIM-DBS with self-reported dysphagia after VIM-DBS were included.
