Research on Hearing, Balance, Taste, Smell, Voice, Speech, and Language Disorders

This observational study aims to collect health information and samples from people with hearing, balance, taste, smell, voice, speech, language, and other ear, nose, and throat (ENT) disorders. The goal is to gather data for future research and to identify individuals who might be suitable for other research studies. You could be eligible if you are 2 years or older and have a history of, or currently have, one of these conditions. The study is ongoing, meaning data collection is happening continuously. No specific treatments or interventions are being tested in this study; its purpose is purely for data collection and evaluation for future research.

Study design
This is an observational study with a planned enrollment of 600 participants. It is not testing any specific interventions.
What's involved
Participants will have their clinical data and specimens collected during diagnosis and treatment. Some participants may also undergo brief sensory testing using food-grade tannic acid solutions.
Compensation
Not stated in the trial record.
Follow-up
Clinical data collection and evaluation for clinical studies are measured as ongoing, suggesting continuous follow-up.
