A novel silicone catheter with an inflatable balloon served as a temporary stent for dacryocystorhinostomy. This method effectively maintained lacrimal sac patency during healing, allowing for simple removal.

Area of Science:

  • Ophthalmology
  • Otorhinolaryngology
  • Biomedical Engineering

Background:

  • Dacryocystorhinostomy (DCR) aims to restore lacrimal drainage.
  • Maintaining patency of the lacrimal sac-nasal fistula is crucial for successful DCR outcomes.
  • Traditional stenting methods can have associated complications.

Purpose of the Study:

  • To evaluate the efficacy of a silicone catheter with an inflatable balloon as a temporary stent in dacryocystorhinostomy.
  • To assess the device's ability to maintain lacrimal sac patency during the healing phase.
  • To determine the ease of postoperative removal.

Main Methods:

  • A silicone catheter featuring an inflatable balloon was utilized.
  • The balloon was inflated within the lacrimal sac, with the catheter positioned in the nasal fossa.

  • The stent remained in place throughout the healing period.

    • Main Results:

    • The inflatable balloon stent successfully maintained an open communication between the lacrimal sac and nasal mucosa.
    • The device facilitated the healing process post-dacryocystorhinostomy.
    • Postoperative removal involved simple balloon deflation and catheter extraction.

    Conclusions:

    • The silicone catheter with an inflatable balloon is an effective temporary stent for dacryocystorhinostomy.
    • This stenting technique ensures adequate patency and simplifies postoperative management.
    • Further studies may explore long-term outcomes and patient comfort.
