Endoscopic ultrasonic dacryocystorhinostomy for recurrent dacryocystitis following rhinoplasty.

UNLABELLED The lacrimal sac is the structure most vulnerable to injury when performing rhinoplastic osteotomies. When performed in a low lateral position or along the frontal process of the frontal-maxillary suture, osteotomies can potentially tear the medial canthal tendon and injure the underlying lacrimal sac, possibly resulting in dacryocystitis. In this case report, the authors discuss a case of dacryocystitis following primary rhinoplasty; this injury was repaired with endoscopic dacryocystorhinostomy (DCR) using a Sonopet ultrasonic bone aspirator (Stryker, Kalamazoo, Michigan) at a single institution. This method achieved nasolacrimal duct patency, and the patient continued to be symptom-free at an 18-month follow-up. This is the first reported case of recurrent dacryocystitis following rhinoplasty as treated by endoscopic DCR. LEVEL OF EVIDENCE 5.
