Abstract

A 74-year-old male patient presented to the outpatient department with left-sided epiphora and chronic dacryocystitis, without any history of head trauma or previous nasal or paranasal sinuses surgery. No abnormalities were noted at the time with the use of nasal endoscopy. The computed tomography scan however revealed an osteoma of the medial wall of the left maxillary sinus. An endonasal endoscopic dacryocystorhinostomy (DCR) with osteoma removal by using a drill with temporary silicone stenting of the nasolacrimal duct system was performed. Due to a granuloma formation at the DCR-window site 2 months postoperatively a revision-DCR was performed and the new window remained patent at control 6 months after surgery.

Histological examination (analysis X2,5) of this slow-growing, bone-forming tumor revealed the presence of dense, compact mature bone in paucicellular fibrous stroma. Large trabeculae of mature, lamellar bone can be seen: mature bone (big arrow) and fibrous stroma (small arrow).
