    Area of Science:

    • Rhinology and Plastic Surgery
    • Biomedical Engineering
    • Medical Device Technology

    Background:

    • Scar tissue and grafts can obstruct nasal passages, hindering airflow and requiring surgical intervention.
    • Maintaining nasal patency after surgery or trauma is crucial for respiratory function.
    • Existing methods for nasal stenting may have limitations in addressing significant tissue contraction.

    Purpose of the Study:

    • To describe a novel technique for nasal stenting using custom acrylic resin implants.
    • To evaluate the efficacy of intranasal acrylic resin stents with integrated mechanical expanders.
    • To address the challenge of maintaining nasal airway patency in the presence of scar tissue or grafts.

    Main Methods:

    • Fabrication of intranasal acrylic resin stents incorporating finger springs and/or orthodontic jackscrew expanders.
    • Surgical placement of the stents to initiate and maintain nasal opening.
    • Monitoring of stent performance and nasal patency over time.

    Main Results:

    • The described technique successfully initiated and maintained the desired nasal opening.
    • The acrylic resin stents with mechanical expanders proved effective in counteracting scar tissue formation and graft contraction.
    • No significant complications were reported during the study period.

    Conclusions:

    • Intranasal acrylic resin stents with finger springs and/or orthodontic jackscrew expanders offer a viable solution for managing nasal obstruction.
    • This technique provides a method for achieving and sustaining nasal patency in challenging clinical scenarios.
    • Further research may explore long-term outcomes and patient-reported benefits.
