Stitch guide technique for bicanalicular nasal intubation in single canalicular laceration reconstruction.

Various surgical techniques for canalicular laceration reconstruction have been described in previous study. But there are still two difficult points which may take time in the operation even with the assistance of magnification. We present a simple and effective way to achieve the bicanalicular nasal intubation for the single canalicular laceration. From Jan 2005 to Dec 2015, 20 patients (21 eyes) with upper or lower canalicular laceration were treated with the Crawford lacrimal intubation set by this stitch guide method. We used the eye pigtail probe and the steel probe of the intubation set to dispose a 4-0 Nylon suture as a guide to pull down the silicone tube to the nostril. The functional and anatomic success rates in the 20 eyes are 90% (18/20) and 85% (17/20) respectively. The average time for bicanalicular nasal intubation by this method is 6.87 ± 1.83 min. The result of stitch guide technique to achieve bicanalicular nasal intubation in single canalicular laceration reconstruction is almost the same as the traditional method. Our anatomic and functional success rates are 85% and 90% respectively which are comparable to the previous studies. But this new method takes less time to complete the intubation with little variation. The magnification with microscopy could be omitted and no new instrument is needed. The stitch guide technique for bicanalicular nasal intubation with Crawford intubation system is a reliable and easy way to perform in single canalicular laceration reconstruction.
