“…Dacryocystography (DCT) and computed tomographic DCT (CT-DCT) are important radiologic tools for evaluating the lacrimal duct anatomy and pathology [2][3][4]. These techniques have been used to study the effect of lateral osteotomies, external and endoscopic paranasal sinus surgery, and dacryocystorhinostomy on the lacrimal apparatus [5][6][7][8][9].…”

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.The anatomic proximity of the lacrimal system to the nose renders possible its involvement during rhinoseptoplasty and can result in postoperative transient or permanent obstructions to the lacrimal flow [1]. In contrast, correction of septal deviations and reduction of turbinate hypertrophy usually reduce the lacrimal engorgement at the level of the internal inferior nasal meatus, ordinarily resulting in an amelioration of the epiphora.Dacryocystography (DCT) and computed tomographic DCT (CT-DCT) are important radiologic tools for evaluating the lacrimal duct anatomy and pathology [2][3][4]. These techniques have been used to study the effect of lateral osteotomies, external and endoscopic paranasal sinus surgery, and dacryocystorhinostomy on the lacrimal apparatus [5][6][7][8][9]. In the current study, we used these techniques to evaluate the incidence of outflow alterations among patients who had septal deviations with or without turbinate hypertrophy but asymptomatic for epiphora and postoperative changes occurring after corrective rhinoseptoplasty. Materials and MethodsWe prospectively recruited patients having septal deviations with or without turbinate hypertrophy who underwent

A large number of different neoplastic, infective and autoimmunologic diseases can affect the lacrimal gland. Thorough imaging examinations can help to characterize lesions to narrow down possible differential diagnoses. Diseases of the lacrimal drainage system, especially obstructions with constant epiphora are often very irritating for the patients. Imaging examinations can assist in selecting the adequate therapy in interdisciplinary consensus. Moreover, interventional-radiological therapy (e. g. balloon-dacryocystoplasty) is an attractive minimally-invasive treatment alternative.
