Active clinical trials for "Glossopharyngeal Nerve Diseases"

This study is an open-label study to determine the feasibility of Motor Cortex Stimulation (MCS) in the treatment of patients with chronic pain of the face or upper extremity. MCS will be delivered by use of an electrode and pulse generator, which are FDA approved for spinal cord stimulation but are not approved for MCS. The study has as a single-arm design with the subject at baseline serving as a control for the response to MCS.

The investigators will treat patients (targeting enrollment of n=20) who suffer from trigeminal or glossopharyngeal nerve pain in the context of painful small fiber neuropathy. The primary pain-related objective is reduction of pain and reduced use of rescue and other anti-pain medications. Another goal is to monitor and confirm the safety profile established in the migraine population, during previous Phase 3 trials.

The blockade of the superior cervical ganglion (GCS) of the sympathetic trunk is a very special form of therapy. The transoral blocking technique, also known as GLOA (ganglionic local opioid analgesia), is very suitable for achieving GCS. A total of 5 μg of sufentanil in 2 ml of sodium chlorid are applied. Since no imaging evidence of the injected substances has been published for a GLOA in a living person, it is planned to carry out an MRI examination immediately after the ganglionic local opioid analgesia in order to show the spread and distribution pattern of the injected substance. It is also planed to show a correlation of the spread of the injected substance with the efficacy of the intervention. To determine the interrater reliability, the GLOA is carried out alternately by 2 different examiners and the existing MRI images of the GLOA are assessed by an radiologist and anatomist in a blinded manner. In a follow-up after 1 and 3 months, the questionnaires and pain scores are evaluated again.

This is a mono center , observational study carried out within otorhinolaryngology department in CH Valence. This is a descriptive and exploratory study in healthy volunteers. Based on the hypothesis that Metallic taste is imperfectly assessed, this study will provide a better understanding of the Metallic Taste.
