Removal of Deep Orbital Tumor through Small Incision Approach

PURPOSE: We report on the effectiveness of the small incision anterior approach for the deep orbital tumor. METHODS: The authors operated on 5 patients with deep orbital tumor using the small incision anterior approach. RESULTS: Five cases , 2 neurilemmomas, 1 orbital dermoid cyst, 1 angiofibroma, and 1 osteoma, were treated surgically with the small incision anterior approach and had good cosmetic result, early recovery, and showed no serious complications. CONCLUSIONS: The small incision anterior approach for the deep orbital tumor has a number of advantages over lateral orbitotomy, including shorter operation time, early recovery and good cosmetic results. Nevertheless, this technique requires a precise preoperative diagnosis.

The Results of Endoscopic Canaliculocystodacryorhinostomy with Two Sets of Silicone Tube Intubation in Canalicular Obstruction

PURPOSE: This study evaluated the effectiveness of endoscopic canaliculodacryocystorhinostomy with two sets of silicone tube intubation in the distal part of canalicular obstruction. METHODS: Endoscopic canaliculodacryocystorhinostomy with double silicone tube intubation was done in 26 patients with canalicular obstruction from January 2002 to December 2002. Probing or trephination was used for recanaliculization of obstructed canaliculi. The silicone tube was left in place for 6 months. RESULTS: The success rate was 76.9% (20 of 26 patients) two months after tube removal. The level of canalicular obstruction or method of bougienage did not affect the success rates. Complications includes granuloma formation (12), synechia of ostium (1), prolepses of tube (2), and acute dacryocystitis(1). CONCLUSIONS: Endoscopic canaliculodacryocystorhinostomy with double silicone tube intubation showed a relatively high success rate and was more effective and convenient than conjunctivodacryocystorhinostomy with Jones tube.
