This study presents a novel transoral surgical technique using a Deaver retractor for safe pharyngeal access via the vallecula. This method is especially beneficial for total laryngectomy procedures.

Area of Science:

  • Otolaryngology
  • Surgical Techniques
  • Head and Neck Surgery

Background:

  • Pharyngeal access is crucial for various head and neck surgical procedures.
  • Current methods may pose risks to surrounding structures.
  • A need exists for a minimally invasive and safe approach to the pharynx via the vallecula.

Purpose of the Study:

  • To describe a novel transoral technique for accessing the pharynx through the vallecula.
  • To highlight the utility of a Deaver retractor in guiding surgical entry.
  • To demonstrate the safety and applicability of this technique in specific surgical contexts.

Main Methods:

  • Transoral insertion of a small Deaver retractor beyond the tongue base into the vallecula.
  • Utilizing the retractor tip to guide pharyngeal entry and access.

Related Experiment Videos

  • Application of the technique during total laryngectomy with or without pharyngectomy.

    • Main Results:

    • The Deaver retractor effectively directs the surgeon to the pharyngotomy site.
    • The technique allows for pharyngeal entry and access without damaging adjacent structures.
    • Successful application in total laryngectomy procedures was demonstrated.

    Conclusions:

    • This transoral Deaver retractor technique provides safe and effective pharyngeal access via the vallecula.
    • It is particularly advantageous in total laryngectomy and related procedures.
    • The method offers a valuable alternative when vallecula entry to the pharynx is indicated.
