Abstract: OBJECTIVES: To analyse the radiological features of the bony nasolacrimal duct before and after functional endoscopic sinus surgery, and document the incidence of surgically induced dehiscence. METHODS: A retrospective case series analysis was conducted of 63 consecutive patients who underwent uncinectomy as a part of 118 functional endoscopic sinus surgical procedures. All patients underwent pre- and post-operative computed tomography scans. Axial computed tomography images at the level of maxillary sinus were evaluated for the presence of bony nasolacrimal duct dehiscence, osteitis and completeness of uncinectomy. RESULTS: The rate of nasolacrimal duct dehiscence prior to surgery was 6.8 per cent (8 out of 118 cases). Nasolacrimal duct dehiscence as a consequence of surgery was observed in 3.3 per cent of cases (4 out of 118), with a further 4.2 per cent (5 out of 118) showing post-operative reactive bony change of the nasolacrimal duct in the absence of dehiscence. CONCLUSION: The incidence of nasolacrimal duct injury observed was much lower than that previously reported in the literature.
