Filter by:Smell/taste disorders are common conditions with a significant impact on quality of life. In September 2021, a specific consultation for patients with smell and taste disorders was initiated at the ENT-HNS (ear, nose, and throat, head and neck surgery) department of UZ Leuven, partly in light of post-COVID-19 related smell disorders. With this observational ambidirectional study, we aim to better map smell/taste disorders in the Belgian/Flemish population. Using standard-of-care diagnostic tests and structured questionnaires, we strive to gain more insight into the severity, impact, and progression/prognosis of smell/taste disorders.
Patients diagnosed with head and neck cancer who receive radiation therapy with and without chemotherapy develop altered sense of taste due to treatment effect, which typically arises in the second week of radiation therapy and progresses throughout the course of treatment. While some symptoms such as pain, mucositis, and xerostomia can be managed with pain medications and saliva replacements, taste alteration has an earlier onset and is a more difficult symptom to readily address and intervene upon. There are no effective established interventions for taste, although this is a major issue in the patient experience. The investigator will be examining they hypothesis that a miracle fruit cube would yield the greatest benefit to improve taste dysfunction in the beginning half of radiation treatment when taste function is decreased but not absent.
Patients admitted for the otosclerosis operation are included in the study. The Narrow Band Imaging (NBI) of their taste buds is performed before the operation. The sensory function of the anterior 2/3 of the tongue is tested with the two point discrimination discs, the taste is tested with taste strips and the SF-36 questionnaire is applied. During the operation in local anesthesia the threshold for the tongue sensation (by the stimulation of the chorda tympani nerve) of the first 2/3 of the tongue at the beginning of the operation (when we first encounter the chorda tympani nerve) and at the end of the operation is measured.One month and six months after the operation the tests are being repeated (NBI, two-point discrimination and SF-36 questionnaire). The study has the National Ethical Committee approval.
This study evaluates the influence of the taste sensitivity, of food preferences and of the reward system on the energetic balance before and after liver transplantation in cirrhotic patients and after kidney transplantation in renal failure patients
This randomized controlled trial aims to investigate hypoglossal acupuncture in comparison to sham acupuncture and standard medical treatment (dietary recommendations) in the treatment of dysgeusia in cancer patients undergoing chemotherapy.
Objectives To evaluate the impact of taste disturbance in different types of chronic middle ear diseases and after middle ear surgery. Hypothesis That patients with chronic otitis media and cholesteatoma has taste disturbance already before surgery due to the disease itself, of course depending on degree of the disease. That patients with otosclerosis, has a normal nerve function before surgery. That patients with normal taste before surgery are more likely to notices a taste disturbance. That nerve in continuity after surgery, even if it is maltreated, gives less taste disturbance than a divided nerve. Methods A clinical study has been launched that measures taste function with two different methods for taste measurements, electrogustometry (EGM) and the filter paper disc method (FPD) before and after middle ear surgery in patients operated with middle ear surgery because of otosclerosis, chronic otitis media and cholesteatoma. The investigators plan to include 120 patients in this study. A parallel study of the patients own experience of the symptom has also been launched were the patients answer a questionary and a quality of life document. The investigators plan to include 300 patients in this study. A histological study where specimens of CTN from healthy ears and from ears with chronic disease will be investigated with electron microscopy has also started.
Oral burning can have a multitude of reasons. Recent neurophysiologic study results suggest that a primary burning mouth disorder (BMD) may be a peripheral and/or a central neuropathic disorder. The aim of this study is to first identify patients with a primary burning mouth disorder by excluding other possible causes for oral burning. By means of qualitative and quantitative sensory testing and a gustatory examination in the individual patient the investigators want to find out whether neurosensory differences exist between patients with a primary BMD and controls and whether gustatory and neurosensory deficits always coexist in BMD-patients.
