Purpose:
|
To assess the computed tomography (CT) findings in patients with primary acquired nasolacrimal duct obstruction (PANDO) who were scheduled for endonasal dacryocystorhinostomy (DCR).
|
|
Methods:
|
PANDO was diagnosed based upon clinical examination, dye disappearance , and diagnostic irrigation test. Coronal and axial CT scan of the orbit and para-nasal sinuses were performed before DCR procedure in patients without prior nasal, sinus or lacrimal system surgery.
|
|
Results:
|
There were 42 patients (12 males, 32 females). Mean age was 58.6 years old (range, 25 to 85 years). CT analysis showed septal deviation to the side of nasolacrimal duct obstruction in 17 patients (40.4%) and to the opposite site of obstruction in 18 patients (42.8%). Inferior turbinate hypertrophy was found on the contralateral side of the deviation in 13 patients (30.9%). Small and large Aggar nasi cell was observed in 18 and 16 patients, respectively. Osteomeatal complex disease was found in 5 (11.9%) and Concha bullosa in 10 (23.8%) patients.
|
|
Conclusion:
|
Different nasal pathologies were found in the majority of this series with PANDO. Nasal deviation was to the opposite side of PANDO in 31% of patients who showed an inferior turbinate hypertrophy on the side of PANDO.
