Abstract
To determine whether simultaneous silicone intubation of the osteotomy and the nasolacrimal duct is advantageous in some dacryocystorhinostomy procedures. Silicone tubing was placed through both the osteotomy and the nasolacrimal duct in two patients who underwent dacryocystorhinostomy for dacryolithiasis. Postoperatively, signs and symptoms of nasolacrimal obstruction were relieved, and lacrimal irrigation confirmed anatomic patency of the tear drainage canals in both cases. Simultaneous intubation of the osteotomy and the nasolacrimal duct prevents prolapse of the silicone stent and may decrease the frequency of postoperative scarring.
