  • Simplified description (AI rewritten)
  • Technical description (Original)

Study Purpose: We are exploring a way to better understand if damage to a nerve in the throat, called the recurrent laryngeal nerve, can heal after an injury. This can help doctors understand more about voice and swallowing problems that happen after trauma.

Study Details: Participants will receive a single dose of an investigational medication designed to help see if there is still a connection in the nerve after injury. This will be done in a safe, controlled setting.

  • Duration: This study involves just one visit.
  • Age Criteria: Participants must be adults aged 18 or older.
  • Condition: Suitable for those with potential nerve damage in the throat from a recent injury.

Key Considerations: The study requires only one visit, and there will be no ongoing treatment or follow-up needed. Participants need to have experienced a specific type of throat nerve injury recently. It's important to discuss with your doctor if this study might be right for you, especially if you have ongoing throat or voice issues after an injury.
