    A novel conjunctivorhinostomy technique avoids bone perforation, creating a more vertical tear drainage tube. This minimally invasive procedure offers improved flow and can be done quickly in an office setting.

    Area of Science:

    • Ophthalmology
    • Otorhinolaryngology
    • Surgical Innovation

    Background:

    • Traditional conjunctivorhinostomy necessitates perforating the maxillary bone, leading to complex procedures and suboptimal tear drainage.
    • Existing methods often result in horizontal conduits with poor flow, impacting patient outcomes.
    • The need for a less invasive and more effective tear drainage solution is evident.

    Purpose of the Study:

    • To introduce a new conjunctivorhinostomy technique that bypasses the need for bone perforation.
    • To describe a method for creating a more vertically aligned tear drainage conduit.
    • To evaluate the efficacy and feasibility of this novel surgical approach.

    Main Methods:

    • A new conjunctivorhinostomy technique involves passing a tube (≤2 mm diameter) beneath facial soft tissues, superficial to the maxillary bone.

  • The tube is positioned between the lacrimal lake and the nasal atrium, avoiding osseous perforation.
  • The procedure is designed for rapid execution under local anesthesia in an office setting.

    • Main Results:

    • The novel technique creates an almost vertical conduit for tear drainage.
    • Placement within the nasal atrium ensures drainage in an area of maximal respiratory flow, improving tear flow.
    • The procedure is minimally invasive, quick, and can be performed with local anesthesia.

    Conclusions:

    • This innovative conjunctivorhinostomy technique offers a simpler, more effective alternative to traditional methods.
    • The improved conduit geometry and placement lead to better tear drainage.
    • The procedure's efficiency and minimal invasiveness make it suitable for office-based surgical practice.
