A Surprise in the Lacrimal Sac

To present a case with recurrent dacryocystitis as an unusual complication of medial orbital wall fracture repair with cartilage tissue graft. A 20-year-old male had facial trauma and underwent surgery to reconstruct right medial orbital wall fracture. During follow-up, he presented with continuous epiphora, mucopurulent discharge from the right eye. A thorough history taking indicated that medial orbital fracture was reconstructed with postauricular cartilage. We planned a standard external dacryocystorhinostomy (DCR). During the creation of lacrimal sac flaps, hard tissue was noted in the lacrimal sac. This tissue was excised and sent for pathological examination. The pathological examination revealed cartilage tissue. There were no further ipsilateral symptoms or complications after DCR. In patients with lacrimal system injury related to orbital wall fracture, iatrogenic foreign bodies in the lacrimal sac should be considered in patients with recurrent dacryocystitis who had reconstructive surgery for facial and orbital trauma.
