• A silicone catheter with an inflatable balloon was used as a temporary stent for dacryocystorhinostomy. The inflated balloon was positioned in the patient's lacrimal sac, and the catheter remained in the nasal fossa. This device maintained an open lacrimal sac—nasal mucosa communication during the healing period. Postoperative removal was performed by deflating the balloon and gently pulling the catheter through the patient's nostril.
