This study presents a new technique for creating custom interlocking tracheostoma vents for patients with complex airway issues. These vents facilitate phonation and maintain airway patency, simplifying patient care.

Area of Science:

  • Medical Devices
  • Otolaryngology
  • Biomedical Engineering

Background:

  • Tracheostenosis can lead to complex tracheostoma anatomy, including bidirectional tracheostomas or fistulas.
  • Existing tracheostoma vents may not be suitable for these complex anatomies, hindering phonation and airway maintenance.
  • Customizable solutions are needed to address the challenges of managing tracheostomas secondary to stenosis.

Purpose of the Study:

  • To describe a novel technique for fabricating interlocking custom tracheostoma vents.
  • To provide a solution for patients with bidirectional tracheostomas or tracheostoma fistulas.
  • To enable phonation and maintain tracheostoma patency in challenging cases.

Main Methods:

  • Fabrication of dual interlocking custom tracheostoma vents using a combination of rigid acrylic resin and resilient materials.

  • Incorporation of a 5 x 10-mm opening in the inferior prosthesis to allow for phonation.
  • Design focused on ease of placement, removal, and patient comfort.

    • Main Results:

    • The interlocking design ensures secure placement and easy removal, overcoming limitations of single vents.
    • The integrated opening facilitates phonation for patients with intact vocal cords.
    • The materials used maintain tracheostoma patency while minimizing peristomal irritation.

    Conclusions:

    • The described fabrication technique is simple and does not require specialized laboratory equipment.
    • Interlocking custom tracheostoma vents offer a viable and effective solution for managing complex tracheostoma anatomies.
    • This innovation improves patient quality of life by enabling phonation and ensuring airway patency.
