Simultaneous silicone intubation through the osteotomy and the nasolacrimal duct during dacryocystorhinostomy
1Department of Ophthalmology, Mayo Clinic, Rochester, MN 55905, USA.
Purpose:
To determine whether simultaneous silicone intubation of the osteotomy and the nasolacrimal duct is advantageous in some dacryocystorhinostomy procedures.
Methods:
Silicone tubing was placed through both the osteotomy and the nasolacrimal duct in two patients who underwent dacryocystorhinostomy for dacryolithiasis.
Results:
Postoperatively, signs and symptoms of nasolacrimal obstruction were relieved, and lacrimal irrigation confirmed anatomic patency of the tear drainage canals in both cases.
Conclusions:
Simultaneous intubation of the osteotomy and the nasolacrimal duct prevents prolapse of the silicone stent and may decrease the frequency of postoperative scarring.
