Background:
This study aimed to investigate the lacrimal flow in patients affected by septal deviations and turbinate hypertrophy and
to evaluate changes after rhinoseptoplasty with dacryocystography (DCT) and computed tomographic dacryocystography (CT-DCT).
Methods:
The study prospectively recruited patients having septal deviations with or without turbinate hypertrophy who underwent surgical
evaluation for correction of their respiratory symptoms and were not referred for epiphora. Patients were excluded if they
had undergone surgery for cranial vault defects or had experienced septal deviations after traumatic accidents. All patients
were studied with DCT and CT-DCT preoperatively and postoperatively.
Results:
A total of 24 patients (10 men and 14 women) were recruited for the study. Of these patients, 11 (45.8%) had a reduced flow
of the medium contrast due to a partial obstruction at the level of the internal ostium. All 11 patients had septal deviations
and turbinate hypertrophy, whereas 8 patients had a unilateral obstruction (72.7%), and 3 patients had a bilateral obstruction
(27.3%). All flows were corrected after surgery.
Conclusions:
The safe and well-tolerated radiologic techniques performed in this study provided detailed imaging of the lacrimal outflow
system. A high incidence of partial obstruction to the internal ostium was found in patients with septal deviations, turbinate
hypertrophy, and no lacrimal symptoms, suggesting a frequent presymptomatic condition.
